valve regulated lead acid battery Portable 20w Solar Charger
I have been charging 18650 rechargeable batteries with a small 12 v battery solar charger for months. No impression of charging speed, spent a whole sunny day, probably only charging a 18650 battery. I decided to take it up to a notch and bought a 20 w 12 v solarpanel from ebay auctions. Now I have to decide to either install the panel outside or plug the wire into the house or turn it into a portable one. I decided on the latter because the 20 w is a bit meager for the roof installation. Studying the charging controller, you can quickly see that the better charging controller is the maximum power point and costs about $100 or more. Maximum power tracking is worth it if you have a roofLoad of solar panels. In this case, only a very basic charging controller is required. This 10 amp unit is basic for just $10. After doing a lot of research online, I believe I 've come up with a nice portable charger that doesn't have much cash.

I used the battery of the computer power backup (UPS) so the cost is zero. Luggage carts, used plywood, etc. Two small pieces 3/8 or 1/2 "plywood is screwed together with 2x2" to increase support. Size is determined by #1: Number of batteries carried on Base #2: spacing of electronic devices fixed on the back panel & #3: size of trolley. I believe I'm using a small frame of the luggage cart. A small bungee rope holds the rear panel to the trolley. The weight of the battery also helps to keep it in place. I used 4 x B. B. Battery HR9-12 valves adjust lead acid (vrla) 12 v 8. The 0 amp hour battery I found on the back of the computer-Start the power supply. These I wired in parallel with 12gw to keep 12 volts & after the design of the ch5 (above), increase the amp hours to 32 hours and the battery pack wiring will be connected to the charging controller. At Home Depot, a roll from the 12 ad hoc working group was selling for nearly $20, so I only purchased a roll of red, hoping that there would be enough black wires around the house that I could use. I don't, so I use the red wire to put a black heat shrink at the end of the negative wire, and some black heat shrink strips are placed every few inches along the length. Place a hard board under 4 batteries that can be lifted together & put into the shoe box that puts them together as a neat package. The 2 wires that connect the battery to the charging controller deliberately leave for a long time to allow the lid of the shoe box to be closed, and the lid creates a small working surface to accommodate items that are being charged. When connected to the charging controller, it is important that the battery is Wired first, followed by solar panels, and finally powered off. Thanks to khaleel123 & the drawing "solar controller wiring" he found on his guided solar panel setup (above), about $100-I was able to wire things up, from solar panels to controllers, with several red and black wires of 14 MB in length. To determine the length I want to be as short as possible. In normal working mode, the aluminum frame of the solar panel will be hooked on the top of the plywood. Not only does this make the solar panel roughly toward the sun, it also keeps all the electronics under it dry, avoiding the occasional rain (I hope! ). Otherwise, the panel only needs to be moved from one side to the other to enter the electronic device. After connecting the pos & neg 14gw from the battery pack to the charging controller, I should add the controller led and I feel like I need some way to understand the state of the battery. In addition to the 3 LEDs on the surface of the charging controller. I bought a 5 digit voltmeter for about 9 dollars. The puppy needs a 9 v rechargeable battery to supply power. To fix this panel on the plywood I useThen, the double sided tape drilled a hole on each side of it & snuggled it back through the zipper. The next step is to connect the wire to the power supply of the charging controller. Connect the barrier wiring plate with screws to the plywood next to the charging controller. I added a 3amp fuse in the main line heading towards it. It's just a guess because I don't know if 3A is enough, so I'll try to figure out the right value in the next few weeks. I think it might be a good idea to include the on/off switch at this time as well. I installed a 4 usb port device on ebay to test the system. It was cloudy outside today, but before the rain forced me to pull things back inside, I definitely noticed some charging. Success! It took me 2 hours to charge my 2100 Nokia phone from 35%. Ordered a 12 v/2x usb/voltmeter from BangGood (as shown above) and I think it fits well here. It has a 12 v power point where I can plug in a power inverter of 300 watts. Does the 300 w Inverter work with 20 w solar panels? I think I will find out. The project is small enough for camping or picnics. It keeps the laptop, phone, flashlight battery charged during the power outage, so it's definitely worth mentioning. I hope you think this is a project worth doing. If you have any questions or ideas for improvement, please pass them on to us! Oh Yeah. I have entered the manufacturing of energy: the United States-Innovation Challenge in MexicoI hope to vote. I believe the button at the top of the right page. I made some changes for the better. I have replaced the 5 v usb charging port with 1 m/2x5 v usb/12 v module. I am very happy, I will explain the reason. Charging my Nexus5 phone or battery using the 5 v usb port I found will never provide me with more power than YMMA. I know my phone is able to accept a higher price and I'm working on this. With a 12 v power point, I tried a different inverter. 300 w, then 90 w, and finally 30 w, which actually works well with this 20 w solar panel. I found that, among other things, I could charge the battery of my grass trimmer. I also tried charging my Nexus5 using the main power cord, but the charging speed is still not improving. My original battery was broken and it was no longer charged. Luckily, a friend donated 3 12 v batteries that were used but still available. I did some research online and found that charging the phone faster, I need a charging cable that can handle more current & a 12 v charging plug that can also handle. I found [Qualcomm certified] Aukey fast charging 2 on Amazon. USB car charger adapter and Anker 0 30 W 2 port®High speed USB 2 with 5 Advanced Micro USB cable packs (3X 3ft, 1X 6ft, 1X 1ft. Using these cables and car charger adapters, I have achieved a charging speed of 1450ma! Of course, this speed is not accurately measured because I don't have a way to measure it, but I know it's close to being accurate because my pnone is charging for less than 1/2 of the time. It is well worth studying if someone wants a faster phone charging time. Thanks to everyone who voted for me in the make energy contest. I got an award that I really value!
