7DayShop Smart NiMH Battery Charger – 12v Solar Shed



In this video I show how I use my solar energy to charge AA & AAA cells for use in the house. I use this 7dayshop smart charger which is based on the Technoline BL-700 family of chargers.

This charger allows you to charge, discharge, refresh or determine the capacity of each cell. It can charge at 200, 500, 700 or 1000 mIlliamps depending on how quickly you want your cells.

I also explain and demonstrate the single-end primary-inductor converter (SEPIC) I use to regulate 12volts.

DIY – Solar Battery Charger



Hi Everyone, I am back again with this new video tutorial.
In this tutorial, I am going to show you how to charge a Lithium 18650 Cell using TP4056 chip utilizing the solar energy or simply the SUN.

Wouldn’t it be really cool if you can charge your mobile phone’s battery using the sun instead of a USB charger? You can also use this project as a DIY portable power bank.

The total cost of this project excluding the battery is just under $5. The battery will add up another $4 to $5 bucks. So the total cost of the project is somewhat around $10.

Charging a Car Battery with a Solar Panel and Charge Controller



If you connect a solar panel directly to a car battery, it will eventually overcharge the battery and damage it. That’s why you need to use a solar charge controller. This is my own design using the latest microcontroller and MOSFET circuitry. It consumes less than 1mA (that’s very little) and has a neat little blue LED that tells you the battery voltage. It can also be connected in various different configurations so you can do clever things like charge two batteries from one solar panel. You can get the PWM5 from www.256.co.uk

Solar Battery Charger maintainer for car, rv, and truck



Addition: 11/30/2015 I was talk’n to a guy who owns a number of trucks parked in Idaho, and he uses these solar chargers. He says he hooked them up directly to his battery and he didn’t put the panel in in the windshield. He mounted it on top/outside some how. So anyone wanting to try this might keep this in mind.

This solar battery charger/maintainer is used to keep the batteries maintained during cold weather and while the vehicle is parked for long periods of time without starting. As I reported in one of my previous videos I have been having a problem with my batteries in my Kenworth T 2000. So I went ahead and bought this 2.5 watt solar charger/maintainer to see if it’ll help keep the batteries up. It’s plug into my cigarette lighter. I’ll get back when I can, on how well it works out. I looked around on the net. It was cheaper and faster just go to Autozone. They had the best price and I didn’t have to wait for it to be shipped. The guy at Autozone said he has a friend that uses this charger to keep the batteries up in his rv and it works great. UPDATE: after 1 wk + I can’t yet vouch for the product. After 3 days sitting the truck was hard to start but it did start.

Addition: 3/18/15. I just tried starting my truck after 2 days beyond the last time started. It will not start. I can’t vouch for this product yet.

★★★★☆ Solar Charger Power Bank Review – FLOUREON 10000mAh Solar Battery Charger – Amazon



UPDATE: When not in direct sunlight, it can take forever to charge. Be patient if you buy this. 19 bucks last I checked on Amazon: https://amzn.to/2mFFJS4

✏️ Quick thoughts to supplement my video demonstration.

Exact product I’m reviewing here: https://www.amazon.com/gp/product/B01FH084UK/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B01FH084UK&linkCode=as2&tag=beaureviawes-20&linkId=BCPYFXFJ2CUK5OZF

I use this for survival type situations (e.g. bug out bag) where you’d like to charge a cell phone, but there may be no electricity. I also use this for long work days while commuting around downtown Seattle. Even charges when it’s cloudy!

📍 Bottom line: would I recommend this product to one of my friends?
👍 Yes, but be patient when it’s charging from the sun.

Harbor Freight 1.5 watt Solar Battery Charger



Tests of output volts and amps produced before and after removing the blinking LED. Both overcast sky and bright sunshine. I hook up a DC to DC Buck Converter and explain it a bit. I run a USB charging port, I charge a camera and a cell phone. I use the panel to make a batch of colloidal silver. I test the panel with a simple solar charge controller. I charge a 12v- 3ah lead acid battery. This solar panel is not weather proof because it’s designed to be used on the dash of an enclosed vehicle.

Here’s a link to the product web page: http://www.harborfreight.com/15-watt-solar-battery-charger-68692.html
Be sure to read the reviews to get a more well rounded understanding of this product.
