Buying A Refurbished iPhone – The Advantages And What To Look For

Refurbished iPhones are loved because they are cheaper and therefore much more affordable compared to their brand new counterparts. These are phones that have had previous owners, but they have been maintained afresh by the manufacturer improving their quality and making them ready for the market again. Apart from the fact that the refurbished iPhones save money because of their affordable prices, they have a number of other advantages that make them popular.

· The refurbished iPhones come with fresh components considering that their problem areas have been looked at as well as worked on. Faulty parts are also replaced and better ones installed so that the phone functions as well as a new one.

· The software of refurbished phones is reliable. The developers handle all previous glitches making sure that every area is addressed hence you get more reliable software and hardware too.

· Because the refurbished Apple iPhones are made available from approved sellers, they tend to be more reliable and trustworthy compared to buying a used phone from a friend. The approved sellers are in close contact with the manufacturer so they are better in control as well as accountability. Your purchase is much safer when you buy refurbished compared to buying used.

Without doubt, refurbished phones do have a number of advantages and you can consider getting one, especially if you have lost your old phone or it became faulty and you do not have the cash to buy a new phone which can be expensive. But even when buying refurbished, there are critical phone areas that you ought to pay attention to.

Battery life – Even though iPhones come with an impressive battery life that can handle more than 7 hours talk time when they are new, continued use weakens the battery. Find out how many hours of use the phone has gone through and consider whether the battery has been replaced. A refurbished phone whose battery has been replaced is a much better choice because it will easily meet your needs.

Screen damage – Also important to look out for is any visible screen damage. The iPhones have extremely hard glass screens, but if the phone had no screen protector, then it is very possible for the screen to have fine scratches. Important to remember is that such scratches can interfere with proper screen reading and they can also have an effect on the responsiveness of touch screen applications. It is most advisable that you choose a refurbished phone that has a new screen or a screen whose visibility and overall performance you can rely on.

Memory capacity – Earlier versions of the iPhone have little memory and this makes it very important for you to find out the memory size of the phone before you buy. The memory should be large enough so that you can perform all tasks and also have an easy time storing applications you are interested in. Evaluate your needs and relate to the memory size before you finally make your purchase.

The Advantages of Portable Solar Generators

Portable solar generators are used when regular electrical power is unavailable, such as during a power outage or on a camping trip. These units collect energy from the sun's rays and convert it to electrical current, which is then stored for future use on a 12-volt battery. This power may be used to run small appliances like a laptop, fan, or refrigerator. Some solar generators are used to recharge batteries for use in flashlights, cell phones, or any other piece of battery-operated equipment. These generators are invaluable during emergency situations or whenever you find yourself away from an electrical outlet.

Solar generators are preferred to gas generators for their safety, accessibility, and convenience. One major drawback of gas generators is that they can be extremely noisy. In addition, they require the user to keep gas on hand, which can present a danger from fire or fumes. A solar generator requires no fuel source other than what is supplied freely by the sun. This means it can be set outside or near a window to safely charge its battery, and when you need to use it the solar generator will provide you with a clean, quiet, source of energy that you can rely on no matter the situation. Generators, whether gas or solar, typically are used when regular power is out or when one is some distance away from regular power sources. In either case, gas may be difficult to get as gas stations typically depending on electricity to keep their pumps running. No electricity therefore will mean no gas. Being able to produce your own electricity with your generator is an intense advantage during times of crisis.

A portable solar generator is perfect for camping trips with the family or for use on a boat or RV. These units are reliably light and are easy to transport from home to wherever you are traveling to. The size of generator you need is going to depend on the activity you intend to use it for. If you are looking for a generator to keep your laptop or phone charged when on the road, a 15-30 watt generator should provide ample power. If you need a unit that will power multiple appliances for you and your family during a prolonged power-outage you will want to opt for a generator that will produce at least 1500 watts of power.

In short, portable solar generators are an excellent option for ensuring one's electrical equipment will continue functioning during outages or on trips off the grid. They supply clean, reliable energy, and are worth considering for anyone interested in solar energy.

The Advantages of Trolling Motor

Trolling or angling is a fishing method that uses baited fishing lines. These fishing lines are drawn through the water while being attached to the rear part of a moving boat. To keep this boat moving, some sort of a special motor must be used. It should be the one that creates little noise so as not to disturb the fishes and spoil the whole fishing experience. This is where the trolling motor comes in.

What really is a trolling, anyway?

This is a small engine affixed to the bow or stern of an angler’s boat (a fishing boat can range from two to four person pleasure boat) that provides source of power for slowly trolling a lure or natural bait through water where fish are sought, or to allow for precise maneuvering of the boat so that the Angler can cast his bait better to where the fish are located for a more bountiful catch. Trolling motors just make trolling a lot easier and productive that you will never want to go back to your old ways again.

These motors usually are electric powered, with a battery providing its energy source. They are often used as an alternative to larger engines for propelling fishing boats to and from preferred fishing areas because they are quiet and they could only create at most a little disturbance. Their small propellers (The screw-propeller as opposed to paddle-wheels were introduced in the latter half of the 18th century ) can usually be lifted, either manually or via an electronic system, from the water to reduce drag when the larger engine is used for propulsion.

Why use them?

There are a lot of reasons why the trolling motors are good. In addition to the fact that it avoids creating a disturbance while fishing, it virtually meets almost any fishing application and personal tastes and preferences. Each trolling motor also comes with built in features that suits either freshwater or saltwater fishing, depending on the consumer’s preferences. There are also other motors that boast their indestructible composite shaft which is guaranteed not to corrode, rust, or just degrade. Indestructible indeed!

In addition to this, there are companies that also provide a wide range of choices for parts and accessories of every purchased motor. This means that the convenience brought about by the trolling motor itself could still be improved. Now what’s going to be better than that?

The Advantages of Portable Air Compressors

Contractors often use portable air compressors. Since these contractors are responsible for many concrete andaving jobs, portable air compressors are easier to use and to transport. These newer interventions make some jobs a lot easier.

In recent years, the sale of portable air compressors hit a high mark and then gradually decreased. Some experts believe this is due to the fact that they were new contraptions that got a good running start, but over a few years lost their appeal. This is changing as we have advanced the technologies. Another reason that sales are on the upswing is because of the housing boom. With all of the new housing developments and new homes being built across the United States, there is plenty of work in store for portable air compressors.

Portable air compressors have the same functionality as standard, traditional air compressors. They usually have tanks that hold up to eight gallons and have the same safety devices intact. The advantage of these offspring of other air compressors is obvious: the ability to transport them from job-to-job. Portable air compressors have wheels that can roll the compressor and are often more lightweight than industrial models.

When buying a portable air compressor, as with the purchase of a traditional air compressor, look for models that are certified by the American Society of Mechanical Engineers (ASME). These models have been tested for quality and safety and are the only ones available that guarantee quality workmanship. An air compressor certified by the ASME will have a label or sticker located somewhere on the unit; parts and accessories should have this label as well. It is illegal in some states to buy or sell air compressors that are not certified by the ASME. Keep in mind that not all portable air compressors are created equal.

The Lithium Ion Battery Advantages

Li-ion battery or Lithium ion battery is one of several types of rechargeable batteries. During the discharge process, the lithium ions travel from the anode to the cathode and vice versa. Let’s know a bit more about the advantages of lithium-ion batteries.

How do these batteries work?

Different types of li-ion batteries make use of different types of cathodes. The cathodes are made of lithium molecules. Generally, the anodes are made of carbon. As with other types of batteries, the chemical reaction that happen between the cathode, anode and the electrolyte generate electric current. Aside from this, the stuff used for these will affect the cost, capacity, performance and the safety of a certain type of battery.

Li-ion batteries, for instance, that feature a lithium cobalt oxide cathode can give you a bit higher capacity. However, they are more reactive because of the lower thermal capacities. Another great option is the lithium iron phosphate. Their life cycle is 4-5 times longer. Moreover, their power density is around 10 times better.

These batteries are of various classes, but they are commonly used in portable or consumer devices like smartphones and laptops. Aside from this, this type of battery is also popular for use in aerospace, military and other electric automobiles.

Given below are some pros and cons of lithium ion batteries.

Lighter and smaller:

These batteries are lightweight but offer higher capacity than other types of products out there. Therefore, it is commonly used in portable devices where the physical specs like form factor and weight are on the list of important considerations.

Energy Density

Lion batteries feature higher density of energy than other types, which means you can enjoy higher capacity irrespective of the size. That is why these batteries are an ideal choice for power-hungry devices like smartphones and laptops. With the advancements in technology, we will have higher capacities down the road.

Self-discharge

Another great characteristic of a Li-ion battery is that it has only 1.5% self-discharge rate per month, which means that it offers longer-shelf life. The reason is that its discharge rate is lower than most of other rechargeable batteries. Here it’s important to note that the self-discharge rate of a nickel-metal hydride is 20% per month.

Fast charging

This type of battery recharges quickly. Usually, it takes a lot less time to recharge than other types on the market.

Open-circuit voltage

Li-ion batteries offer high open-circuit voltage compared to other batteries like nickel-metal hydride, lead acid and so on.

Lifespan

These batteries last longer than other batteries. Even after hundreds of recharging cycles, it will retain its capacity. For instance, some batteries of this type loss only 30% of their capacity even after 1000 cycles.

So, this was a description of Li-ion batteries and their advantages. If you have been looking for a good battery for your needs, we suggest that you take into account this type first. Due to the number of advantages they offer over other types, your best bet is to go for this type.

The Advantages of Solar Energy for Kids

The amazing energy coming from the Sun has been powering life on Earth for billions of years. Even though sunlight is Earth's primary source of energy, man has recently learned how to harness it in order to use it to his advantage, although plants have been doing that since the dawn of time (capturing the energy of sunlight and converting it to chemical form – photosynthesis). It is vital to pass on this information and technology to our children, so that they can develop it further and slowly eliminate the use of fossil fuels for generating energy.

Teaching children in an early state of their development about the benefits of solar energy will ensure the comfortable lifestyle of our lineage, since in a century or so, mankind will not be able to depend on polluting fossil fuels anymore. This will also implement a responsible, ecologically-aware behavior that we want our children to have in the future. Here, teaching children about the devastating effects fossil fuels have on our environment is a key factor that will insure our survival and well being.

Aside from the fact that children could be taught about the benefits of solar power in schools, they must also see it in action, and what better place to do that than in their own homes? Since young children have a tendency to be very curious about what surrounds them and imitate their parents' behavior and practices, owning a solar panel and explaining this choice to your child will make him learn about sustainable living.

For a young child, learning about solar power and panels may be too complex to forgive, so you can also introduce this technology to your child by buying all sorts of solar-powered toys and experimental or science kits that allows him to experience the different uses of solar power and learn about the principles behind solar energy.

Parents can also help their children build their own solar device from scratch, using the information given on educational websites that include how-to guides to making, for instance, a solar power recharger or home-made hot water system.

Renouncing our habits and changing our mentality by becoming more protective towards our environment and replacing a comfortable but pricey way of obtaining the energy we need to sustain our lifestyle is a process which will take some time, but will bring worldwide benefits. By doing that, we are making a change that our children will only have to improve in the future.

The Advantages and Disadvantages of Transcribing

As a Virtual Assistant, one of the services you may want to consider offering to your clients is transcription. While it sounds easy enough (you listen to an audio tape and just type what you hear), it’s much more involved than that.

There are advantages and disadvantages you should consider before making your decision to offer transcribing services.

According to the Merriam-Webster Online Dictionary, the official definition of transcribe is “to make a written copy of” or “to make a copy of (dictated or recorded matter) in longhand or on a machine (as a typewriter).” Now before you drag out your trusty old typewriter, you will need to make sure you have a few things first. Most importantly, you will need a good computer with a high speed internet connection and both transcription and word processing software installed on it because that old typewriter just isn’t going to do the trick anymore. Some other equipment you will need is a quality headset, a comfortable chair in a quiet room, and if you’re serious about doing transcription, a foot pedal (preferably the USB kind). Depending on the format used (DVD, mp3, cassette, micro-cassette, etc), you may need additional equipment for audio playback. Of course, to be an efficient transcriptionist, you must also have a pretty decent typing speed, good listening, spelling and grammar skills.

Here are some of the points you will want to take into consideration before you decide to offer transcription services:

Advantages:

Pricing is pretty straightforward (by the word, page or audio minute/hour)

Sharpens your listening and typing skills

Opportunity to learn about new and interesting topics

Can turn into a long-term client as transcription can easily lead to other projects (editing, proofreading, article writing or creating an ebook)

Pre-recorded audio gives you the flexibility to transcribe anytime (excellent for those who are trying to juggle a 9-5 job too)

With some additional education, you have the ability to specialize (i.e. medical or legal transcription) and charge a higher specialized rate

Disadvantages:

Some equipment and/or software may need to be purchased (headset, foot pedal, etc.)

You must have a decent typing speed or you are not going to make much of a living doing transcription

Sound quality, multiple speakers, accents, people talking over each other, and audience interaction can significantly slow down the transcription process causing frustration and reducing productivity

Templates provided by client may be difficult to work with

Transcription is not multi-tasking friendly; you will need to concentrate so no telephone calls or tweets

Real-time transcription requires that you and the client are available at the same time. This does not allow time for editing, or breaks

As with any task you perform for your client, you will need to ask some important questions before you get started.

You should be ready with a checklist of some kind, because finding out certain information ahead of time will save you time and aggravation. Some questions you should ask your client before transcribing:

What will the client ultimately do with the transcription (i.e. create an article or ebook)?

What form is the audio in (DVD, mp3, cassette, micro-cassette, etc)?

How will you receive the audio (mail, email, etc)?

Does the client want a hard copy or just the electronic file?

What form do they want the final product in (Word, PDF, etc)?

Do they want verbatim or do they want umms and other unfinished thoughts edited out?

How many speakers are there?

Do any of the speakers have accents?

Are they just looking to have the words put on the paper or are they looking for something that is proofread, edited, and in the final draft stage?

Does the audio include any confidential information?

o Will the client require a Non-disclosure Agreement in addition to the Virtual Assistance Agreement?

o If it is medical transcription, will there be HIPPA compliance issues involved?

If you do decide to venture into the realm of transcription, make sure you have all the necessary tools in place to make your journey a positive experience. Take your time when creating your proposals and make sure you understand all the details of each transcription project. If you are not sure of the terms of the project, contact the client for clarification.

You don’t want to get in over your head and disappoint your client and yourself.

Consider taking on a couple small “trial” project before officially offering transcription services on your website.

Volunteer to transcribe a meeting or two for a church or civic group to gain some experience. You might even suggest a trade and get a client testimonial for your business! Either way it is an excellent opportunity to try out transcription, and see if it is worth adding to your business.

If you have the typing, spelling, and grammar skills that transcribing requires and you are willing to invest in some equipment to get started, then transcribing may be for you. Transcribing can be frustrating and tedious at times, but it can also be a rewarding, interesting, and flexible service that you can offer to your clients. While it has advantages and disadvantages, always keep in mind transcribing is a perfect springboard to additional services you may want to market to your clients to keep your business flourishing.

What Are the Advantages of Electric Bikes?

"In a systematic energy flow comparison, a grid-charged battery driving an electric motor will provide mechanical energy about ten times more efficiently than a human eating a typical diet. lowest environmental and personal monetary cost, usually without increasing urban travel time "
From Energy, Global Warming, and Electric Bicycles Energy Flow Analysis with an Emphasis on Personal Transportation

1. Hill Climbing
That may sound obvious, but it's the primary advantage. A good electric bike effectively flattens hills, increasing your average speed and eliminating the 'groan' factor when a gradient comes into view. Provided you supply a reasonable amount of effort, you can expect to climb hills of 1 in 10 (10%) on an electric bike with ease, and clear a maximum gradient of 1 in 7 (14%), or much more. In hilly country, the effect is nothing short of miraculous.

2. Safety
It sounds illegally, does not it? But the mathematics is compelling. Think of a steep and busy road, with cars climbing at 30mph. If you previously slogged up the hill at 6mph, but can tackle the same gradient at 12mph with an electric bike, you will see 33% fewer cars, and they will pass you at 18mph rather than 24mph. Or at least, we think that's correct.

Whatever the figures, there's no doubt that an electric bike helps to keep you out of danger. The same general principle applies to road junctions – the faster your acceleration, the sooner you can get out of trouble. And with no need to rush the hills, you will not be tempted to ride downhill at breakneck speed … another useful safety feature.

3. Personal Fitness
Surely a conventional bike will keep you fitter? That, of course, depends how much – if at all – you use it. Research (b) has found that 46% of conventional bikes are used only once or twice a week, with a further 30% being used once a fortnight or even less. By contrast, a recent survey of electric bicycle owners reveal that a third ride their bike at least once a day and 81% use the bike at least once a week (c).

The figures confirm our experience that an electric bike typically gets used at least twice as often as a conventional machine.

Because riding an electric bike is a great deal more enjoyable in hilly country, into strong winds, or when carrying heavy loads, users tend to make better use of them. The motor provides up to half the effort, but more regular use means more exercise for the rider.

4. No Sweat!
Sweat may not be a serious issue when you're out for a leisure ride, but it's more important if you're cycling to work. Although some employers are rather grudgingly providing showers and other facilities for cyclists, the great priority has no intention of doing so. An electric bike eliminates the problem at source. In hot weather, it's possible to maintain a normal schedule by transfering a bit more load to the electric motor. In colder weather – or if you feel in need of exercise – just throttle back, or turn the motor off.

5. Clean & Green

Electric bikes obviously consume energy, where a conventional bikes does not (provided we ignore the environmental cost of growing and processing food – see below). However, the amount of energy used is very small compared to a moped, motorcycle or car. Beside fuel, the only consumables are the batteries, and these can normally be recycled when life-expired. As for energy use, electric bikes typically consume fuel at an average rate of 100 to 150 watts of electrical energy, against 15,000 or so for a car (admittedly traveling much faster). In terms of fuel consumption, an electric bike achieves about 800-2,000mpg (290 – 700 liters / kilometer) (d). No other commercially available vehicle can match figures of this kind.

If it's hard to place these numbers in your own lifestyle, think of a 100 watt electric light bulb burning for an evening – that's enough energy to propel an electrically-assisted bike for 20 to 40 miles …

6. Genuinely Sustainable
There's a lot of nonsense talked about sustainability in transport, but an electric bicycle can be made genuinely sustainable. Purchase electricity from a 'green' supplier, or generate your own with a roof-mounted windmill or solar panel array (see Solar Power facts), and the vehicles' fossil fuel consumption will be zero. Surely a conventional bike does that already? Only if you grow the food you consume whilst driving it. Unfortunately, most modern food production and distribution is so fuel-intensive that the consumption of a typical cyclist is not terribly good.

7. Faster travel
In theory a car can average a high speed, but in practice speed often falls below 10mph in cities. The problem is congestion – motorcycles get around this to some extent, but they're still bound to the road network. An electric bike can maintain a higher average speed than a bicycle but take advantage of the same network of cycle facilities, giving access to routes that cars and motorcycles can not reach. The result is often a faster door-to-door journey time than any other mode. And by taking advantage of the uncongested cycle network, but eliminating hills and headwinds, electric bikes are often the most consistent mode of travel.

8. High Resale Value
Electric bikes are new technology, and it's early days yet, but the evidence points to a much better resale value than a conventional bike. True, a typical electric bike costs more to buy, at £ 400- £ 1,000, but it seems you'll get most of that back if you sell the machine on.

9. Motorized, Without The Red Tape!
You know how it is … MOT due, log book missing, insurance costs rising year on year. Electric bikes are treated just like ordinary bicycles for legislative purposes, so there's absolutely no registration or legislation to worry about. You are of course free to insure the machine if you wish, but there's no compulsion to do anything but enjoy yourself!

Advantages and Disadvantages of Cable TV

Cable TV has been facing increasing competition from other communications types like satellite television and even such computer sites as Netflix. With all of these options now available, it is a good opportunity to look at the pros and cons of cable television. In this article, I will examine three positive and three negative points about cable television, to help you make an informed decision.

Advantage #1: Stability

Cable television is especially stable in its service. Both traditional air-wave broadcasts and modern satellite television can and will cut out on you during any serious storm (and often during some not-so-serious storms). Cable, on the other hand, will only go out if there is some flaw in the overall system, like a broken cable or router. This will happen far less often than rainstorms, so cable television will provide far more consistent service.

Advantage #2: Bundling

Often specials are available by bundling your cable television with other services in a single package, usually internet and phone, but sometimes services like cellular phones. These bundles can actually save you quite a bit of money, especially if you bundle all three typical services together. It also provides the convenience of having a single bill.

Advantage #3: Price

Cable television can actually be fairly inexpensive, if you don’t add too many options. The initial hardware costs are fairly inexpensive when compared to satellite, and the FCC requires that all cable companies provide a basic cable package consisting of broadcast channels and a few local channels. As a result, cable television can be the cheapest form of television aside from buying an antenna.

Disadvantage #1: Annoying Monopolies

Many areas only have a single cable television provider, and this creates a monopoly. While the competition from satellite is increasing, the corporate culture of these monopolies is especially poor. Customer service can be terrible, if not non-existent in many cases, and consumer satisfaction with cable TV companies is consistently some of the worst among any companies in the United States.

Disadvantage #2: Confusing Price Packages

Many cable companies are very confusing when it comes to how much their service will actually cost in the long run. Many require you to sign up for two years in order to get a one-year introductory deal. However, you have to really dig on their websites to find out how much the second year will cost. In other cases, there are hidden fees, rental charges and taxes.

Disadvantage #3: Privacy

If you are bundling your cable television with your internet (and many people do), you will have less privacy on the internet. Cable internet works with a stable IP address that doesn’t change, so people will be able to easily track your visits to their sites. Compare this with DSL, where you can easily reset your IP by turning your modem on and off.

With these advantages and disadvantages in mind, you will be in a better position to make a decision about whether to choose cable television.
