I Own and Have Reviewed a Lot of USB Battery Banks.
As you can see in the video, the LiPO cells in this 8000mAh battery bank are high quality. The circuit board, soldering and components are of high quality. Even the built-in LED flashlight help to set this product above the competition.
I always recommend that people don’t buy these for the solar charging capability, instead buy it for the battery bank features. There just isn’t enough surface area to fit enough cells for a stand-alone charger. That being said, it does make a nice addition to the feature set. You can leave it topping up on your desk or dash to keep it ready to use. Think of the solar cell as a top-up or battery maintainer feature.
Overall design is higher than I’ve seen in other solar USB chargers. As you can see in the video when I take it apart, the components are all well engineered and fit nicely. Every possible place where water can get in has a sealing mechanism. Based on my testing for the video, I would call the IP rating at 65. Meaning it is dust proof and water resistant. There are just too many places where water can leak in for it to be completely waterproof. If one were so inclined, one could take it apart and silicone the places that don’t seal well to give it a true IP67 rating. Basically, it can take the rain and probably a brief accidental dunk in water, but don’t expect it to hold water-tight underwater.
Testing with a constant current load resistor, I got a battery capacity of over 7800 mAh when correcting for voltage loss conversion (USB mAh reading multiplied byt 1.35). This is better than I have seen with my other battery banks, so the cells are worthy. Make sure you give it a good charge when you first get it and keep it maintained (I.E. let it sit in the sun for a few days every now and then). Max output amps in any combination of the 2 USB ports was 2.3Amps. It will output as many amps as you need on either port. Don’t freak out about one port being 1 amp and the other being 2. Your device will only pull as many amps as it wants (an ipnone is usually around 1amp or less). Both ports output up to the max amps. 2.3 is pretty impressive.
Capacity (Corrected): 7804mAh
Max Amp Output: 2.3amps
IP Rating(Very informal): IP65
I have seen some reviews freaking out about over-charging with the sun… Don’t worry about it! The cell only outputs 120mA. They didn’t add over-charge protection via the solar cell because 120mA is actually good for the battery to keep it maintained. The quality of the charging circuit is top notch and you are getting a well regulated volt and current output. That is what you don’t get in the cheapo battery banks. It will protect itself and whatever is plugged into it.
+ 8000 mAh!!!

The earliest recorded method of water filtration dates back to 2000 BC where hieroglyphics depict methods of boiling water, placing hot metal instruments in water and filtering water through charcoal and sand. These early methods are thought to have been instituted to make water taste better, that, cleaning it. Water filtration was further developed with the advent of the microscope, which made it possible to see foreign particles and contaminants in water that would have otherwise been considered to be pure and clean. Most notably, the microscope was responsible to identify cholera bacteria in drinking water during a disease outbreak in 19th century London. The outbreak was rampart in all areas except those areas where drinking water was filtrated through sand. Chlorine was also discovered to be an effective, chemical disinfectant capable to rid the infectious water of cholera. It was further discovered that the chemical, chlorine, when used in combination with sand filtering, was effective in combating cholera as well the water borne diseases, typhoid and dysentery.
In an effort to achieve drinking water purity, chlorine disinfection and sand filtering became prominent methods of municipal water treatment through Europe, and then, the US. These primitive methods of disinfecting and filtering water to achieve purity have been studied and evaluated with the use of technology. Chlorine, whose history of ridding water of contaminants, is a poison. It has since been found to exhibit side effects that aggravate and inductive respiratory complications, such as asthma. The poisonous chemical vaporizes at a faster rate than water, making it dangerously harmful when inhaled, especially during showering. Fluoride has since been added as an additional chemical disinfecting agent, but also has side effects of dental damage and other health complications in young children. Lead and other chemical contaminants and by-products further compromising drinking water during the piping and delivery of treated water.
Business and industry have been instrumental in the disposal of waste materials into our fresh water supply sources. This inhabitation has directly contaminated the water supply and also upset the balance of water flow and creation established by nature. The US Clean Water Act, legislated in 1972, was intended to restore the physical, chemical and biological balance of water that had been disturbed by contamination. The Act specified that all natural water supplies would, at least, be safe for fishing and swimming by 1985. This specification led to the development of some form of water filtration and disinfection in every US city as well as advanced technological innovations in the filtering of water used in industry. Even so, the severity of past and continued damage has left more than 1/3 of all water supplies still polluted with contaminants.
In an effort to reduce the contaminants in drinking water and also to comply with national efforts to make drinking water safe, water-filtering systems have been developed to filter water within individual homes. Systems exist to filter incoming water for the entire house and systems are also designed to filter water, inline, at various points of water distribution within the house, such as at faucets and refrigerators or in water pitchers. The US based company, Omnipure Filter Company, credits its own with developing the first small, disposable, inline water filter in the world. The Omnipure CL Series of water filters, developed in 1970, were carbon-based, inline filtering systems designed for water coolers and ice machines. This benchmark water filtration system used granular activated carbon (GAC) to create cost effective methods of filtering water inline. Advances in the functionality, using the same basic design, have since led to the development of whole-house filters, faucet filters, countertop filters, pitcher filters, refrigerator filters and portable filters for camping.
In 1996, KX Industries developed and supplied the first refrigerator water filter for ice cube and cold water dispensing. KXI is credited with developing the initial end of tap filter for the Proctor and Gamble / PUR and the Clorox / Brita water filters. The new technology has been adopted and revised to suit a number of refrigerator models, creating a $ 200 million refrigerator water filter market.
Today, http://www.FiltersFast.com , the leading online retailer of refrigerator water filters, carries filters for every major brand of refrigerators tht filter out anything from Chlorine to Lead and pesticides. They recommend that your filter be changed at least every 6 months to keep your water at it's best quality.
With so much information about the contamination of drinking water supplies in the news lately, many people run right out and purchase a home water filter to reduce and remove contaminants of health concern. While we agree, the best way to battle the ever increasing threats to our drinking water is to use a water filter, not all filters are created equal.
Turns out the most popular water purification products DO NOT reduce or remove the most dangerous water contaminants. As consumers, we have a right to know if the products we buy do what they say they will do. For water filtration, we expect the unit purchased will clean our water and make it safe to drink. But, is the filter purchased doing the job? How do we know?
Enter NSF International
NSF International is an independent agency dedicated to public health and safety. NSF does not mean National Science Foundation as some may think. NSF was founded in 1944 as the National Sanitation Foundation, they changed our name to NSF International in 1990 and expanded their services beyond sanitation and into global markets. The letters in the organization’s name do not represent any specific words today.
Manufacturers, regulators and consumers look to NSF International for the development of public health standards and certification programs that help protect the world’s food, water, consumer products and environment. Their mission is to protect and improve global human health. As an independent, accredited organization, they develop standards, and test and certify products and systems. They provide auditing, education and risk management solutions for public health and the environment.
NSF and Water Purification
When making a water filter purchase, it is important to do the research. Look for the NSF seal of approval. Then read the fine print. Products are certified for many aspects by NSF. The seal on some water filter products is actually not for the contaminants it reduces, but rather for the durability of the unity itself. So look at the fine print to see what is actually certified. Or better yet, visit NSF International’s website and look up the brand you are considering. Find out why it is certified.
Here is a good image comparing some popular home water filtration products.
Everyone should use a quality home water purification system to insure that their water is safe to drink. The purchase of a water filter must be taken seriously so the correct filter is purchased. There is a lot of information on the quality of home water treatment products. Make sure you are purchasing the one that will reduce the most contaminants.

Hi all, Bought this Solar Power Bank with 20000 mAh Li-polymer battery with Qi protocol Wireless charging, (three) 3 USB output for Charging and having Led light as backup with 786 lumen and with ip65 rating yes it is water proof too.
If you don’t want to watch entire video or jump to your desire part at given play time.
Weight Measurement at : 00:58
Size Measurement at : 1:20
Wireless charging at : 1:41
Led Light comparison at : 2:23
Water proof test at : 3:55
Watts measurement at : 7:55
Draining the battery to zero at : 9:26
Solar Charging at : 10:25
Watts output measurement at : 11:49
After through test, i like to share my experience, First of all the backup power, this solar power bank comes with 20000 mAh
lithium polymer battery pack, according to my test, it should have the capacity of at least 15000 mAh or more, with an average of 4000 mah for a mobile phone, it can recharge 4 times for sure.
From 100% power, it charged 73% of iPad with battery capacity if 11,560 mAh is = 8438 mAh
GoPro 3 batteries with capacity of 1220 each 1220×3 = 3660 mAh
Samsung Note – 5 charged from 50% full capacity is 3000 mAh = 1500 mAh
Testing led lights, wireless and USB = 2500 mAh
Total mAh transferred = 16098 mAh
# SECOND (output ports) : this solar power bank has THREE USB output with 11 (Eleven) watts max from a single port or three ports combined and 5 watts for wireless charging if used separately, Wireless charging is very helpful while you are driving or traveling, just the keep the phone over it that’s it simple.
Charging Input is at 5 watts and it is through a micro USB A port ( which would be better if it is a USB-C port and supports a
wireless charging) IT will take one and half day get completely charged from zero percent,
# THIRD (LED light), If you are a traveler or a frequent hiker or like champing in the wild it can light-up the entire tent
having 10×10 square feet for entire night without any worries, even if it dose not have the power to charge other device
# FOURTH (water resistant) : Yes it is a water resistant, can withstand or survive water splash or rain or snow, as it was
mentioned as water proof in another website (a kick stater website) and tested it by putting it under water for FOUR TIMES
inside the breach, It survived all the dips.
NOTE : Water entered the device while submersed but the device is not effected at any manner,Switches worked fine, the output port worked fine, led lights worked fine and wireless charging worked fine.
# FIFTH the last SOLAR charging: I really had a doubt from the very first of having this Solar powerbank, as this small solar
panel can power up or charge those huge 20000 mAh battery. After completely depleting the power to nearly 5% or less, tried it to charge with solar panel, for first few minutes like 30 minutes there was no sign of power in solar indicator bulb, but after 45 minutes it began to light up slowly and after nearly 4 hours under the scorching sun it charged the battery to nearly 25% the first led (25%) started to show up, it is about 5000 mAh or in between 4000 mAh is charged, that is a great you can charge a 3000 mAh battery device.
Note : the SUN light is very strong and high in my place as it is Summer, The temperature of the power bank went up to 60 degree Celsius, where day temperature was at 38 degree Celsius Max, solar charging is working fine, recharging with solar panel is according to the power of Sun light and it will take some time to charge very few percent of Huge 20000 mAh battery
Pros (+) and GOOD points of this Solar Power-bank
# It powers off automatically without draining power still good for the next time. It has 4 blue LED’s to indicate remaining power
# it will easily charge your phone multiple times.
# It is rugged, solid, and feels heavy duty. It has a nylon loop to be attached to backpack or survival gear, comes with 3 outlets and a portable QI wireless charge
#just a bit bulky, but very useful.
#The light lit can lit a whole room or a camping tent
#Excellent power bank for traveling or camping.
Only problem so far found is If you submerge or drop the power bank in Water, Water seeps in to the unit but dose not get damaged.
Tried it for few time (nearly 4 times used its full power backup)
NO ISSUES FOUND…
So far so good

Do your homework and you'll see that the energy efficiency factor makes finding the best tankless hot water heater worth the effort. Energy efficiency is just one way to look at this. Important points given here will guide you in choosing the best tankless hot water heater to fit your needs.
The measure of efficiency
The DOE uses EnergyStar ratings to help consumers find the best tankless hot water heater, or other appliance that will save them money. Electric tankless hot water heaters are rated .99 Energy efficient, while tankless gas heaters are rated at .80. The difference comes from the loss of heat in the combustion process of gas burners. Tank water heaters have an even lower efficiency rating.
If the cost of electricity is competitive in your area, factor in the long-term cost when making your decision. Even so, gas may still be your best choice for a tankless hot water heater. Only gas can produce enough hot water for a large home.
Here are some numbers to give you a rough idea: Electric tankless models produce a flow of only 2-5 gallons per minute of hot water, while gas models can produce 9-13 gallons of hot water per minute. Using multiple units is a way to custom fit tankless models to fit your needs and reduce wasted energy.
For your reference, a shower, with a water saver nozzle uses 1-to to 1-g gallons per minute. A tub or clothes washer uses about 2 to 2-g gallons per minute.
It was once understood that natural gas was the better value, but times change. Do not assum, compare utility rates for your area. A lot has changed in recent years. The cheap price of gas that once made a 65 percent efficiency rating for home heating needs a bargain has changed.
Now with competitive electric power in some areas a 99 percent efficient tankless electric could really be your best tankless hot water heater.
For instance, in the US:
Electric prices vary from $ 0.06 / kwh to $ 0.23 / kwh ($ 1.76 to $ 6.74 a therm) Gas prices vary from $ 10 to $ 19 per 1,000 cu ft of natural gas ($ 1 to $ 1.90 per therm)
In northern latitudes, where ground temperature may drop to near freezing, it takes a lot more energy to heat a gallon of water. This could call for the power of a gas model, depending on your rate of flow needs. It's these two things: Flow Rate and Gallons Per Minute that determine what size heater you need and whether it should be gas or electric.
It pays to do your homework here too. Few contractors are experienced in advising you on choosing the best tankless hot water heater and how to install it. Look for experienced people and get multiple estimates. Gas tankless hot water heaters need to be installed by a knowledgeable technician.
If you are comfortable with your handyman skills, consider installing an electric tankless, if you are on a low budget. These are much easier to install. A good how-to book and the manufacturer's manual should be help enough.
HHO gas car conversions have been seen in the news. Why are these conversions gaining in popularity? It is because they are increasing gas mileage by 20-50%. Some are seeing these vehicles as a water hybrid car by supplementing HHO gas with you gasoline or diesel fuel you could save money at the pump.
HHO gas kits do not come cheap. Even ones found on popular auction sites sell for hundreds of dollars. If you have a few vehicles you would like to convert this could add up.
How this gas works is that it is generated in a cell full of water and a catalyst such as backing soda is contained in that cell alone with a few or many plates usually stainless steel that is similar to a battery. The designs can vary. The cell is hooked to your cars battery to help with the process of electrolysis to generate a gas. The gas is introduced into the intake manifold of your car or truck using the assistance of your vehicles vacuum. By using this gas it should increase the efficiency of your engine so resulting in better gas mileage. Larger engines may require 2-6 cells but that is not usually an issue a typical cell is about the size of a quart jar.
You may have seen reference to these HHO gas cells online or in forums as hydrogen on demand or even hydrogen cell. This is not exactly pure hydrogen it produces but the effect is similar.
The parts to build a home HHU gas conversion can easily be found around town. A really savvy shopper can build a cell for around $ 60 and anyone who uses their hands or likes to build stuff should have not problem constructing a home conversion kit. When the conversion is made to the motor very little modification is needed to the vehicle.
HHO gas technology is still considered experimental but it is a supplemental fuel additive of sorts that could help you increase mileage, increase horsepower, reduce emissions while providing a quitter and cleaner engine. So why not convert your car to burn water?
The life of refrigerator water filters is dependent upon the volume of contaminants in the water as well as the amount of use of the filter. Well water is more likely to contain contaminants not found in publicly treated water and may need more frequent filter changes. As a rule of thumb, the filter should be changed as specified by the manufacturer or at least every six months.
Carbon is the primary substance used in water filtration methods because carbon has the potential to absorb many of the chemicals found in water. Most refrigerator water filters, which meet NSF / ANSI 42 certification standards, use granular activated carbon (GAC) to attract chemicals and impurities responsible for bad taste and odor, such as those that are a by-product of chlorine. These filters are not capable, however, to rid water of more dangerous, health-threatening contaminants. The method by which water is channeled through GAC filters does not allow sufficient time to complete the absorption of such substances. Various bacteria are formed, trapped and allowed to multiply, which further contaminates water processed by the filters. Carbon is not capable to absorb heavy metals, such as lead. GAC filters may trap some heavy metals and sediments, but allow others to filter through to the output water. Failure to change the water filter, every six months, allows unabsorbed water contaminants and newly formed bacteria to saturate the filter, forcing the filter to leak contaminants back into processed water. The water output may contain more contaminants than the filter was intended to remove in the first place.
Technology has lead to the development of more absorbent carbon-based filters, solid carbon block filters. These filters include solid blocks of carbon to absorb contaminants from water. Water takes longer to strain through carbon blocks than it does carbon granules, so that carbon blocks provide sufficient time for the absorption of more health-reducing containments. While carbon block filters are capable to absorb toxins, pesticides, TTHM's and other contaminants, they can not absorb heavy metals or contaminants that are by-products of agricultural fertilization, such as nitrates or sulfides. The composition of carbon blocks allows them to restrain heavy metals and bacteria away from output water, however, nitrates and sulfides are not filtered. Even so, carbon block filters are sufficient to meet NSF / ANSI 53 certification standards. Failure to change carbon block filters, every six months, allows contaminants to saturate the filter, forcing the filter to leak contaminants into the processed water. When sediments are not removed from water, those sediments buildup and corrode filter fittings and water fixtures, causing them to leak. This type of damage to filters and fixtures may cause the output water to contain more contaminants than the water input to the filter. Failure to change the filters may also reduce the water pressure, within the filtering system, forcing it to be ineffective.
Some refrigerator water filters may include fiber water filters. These filters are made of tightly wrapped fibers of rayon or spun cellulose, which trap rust, lead and other sediments found in water. When used alone, these filters are ineffective in reducing any chemical or health-reducing contaminants. Fiber filters are best suited for use with other types of filters to reduce the concentration of sediments. They should be replaced, every six months, to avoid a build-up of sediments that would force the filter to leak the contaminants back into the processed water.
