How to make a SOLAR POWER BANK Charger for mobile (Dual USB 5V 1A 2 1A)

In this video, I am going to show you how to make a Solar Power Bank Charger with 1000mAh capacity. I am going to use USB 1A 2.1A Mobile Power Bank Battery Charger and 4pcs of 18650 Batteries as major parts for this DIY Project.

Required Materials:

8. 4mm Wood Panels

*I love my new solar **Generater.Systems** . It has the right amount of charging power for my needs and the light weight makes the portability idea.*

You are good at a Power bank device with two solar panels. The good thing about the Power Bank module with the led lcd screen is that it shows the battery level in percentage. I used the same module for your Power Bank as yours with the led lcd screen.

I like the idea, in fact i will replicate most of it. But I have a few concerns. 1. I rather make this a 3S. 2. Can't cross wires. 3. Make a bracker for the first panel so is not touching the batteries and last. No exposed wires!

How did you connect the panels series or perral?

[atulmaheshwari]

nice idea it also shows the battery power left amazing!!!

[rudradeepchatterjee]

Which metal strip you used for spot welding?

[sejalpozzi]

Are you missing a potentiometer from the buck converter? Your component seems to be slightly different in appearance

[ikhlaq]

How long will the solar take to fully charge the bettery if gets good sun. And why did you use 6v solar panels? What the bettery output in volts?

[YogeshKumar-jstx]

How much time it takes to charge fully by solar ?
Nd nice design😎

[pradeepgupta]

Did you connect two solar plate in parallel or series ? Can we use 5v 100ma two solar plates with this step down board

[kiranvirdi]

U r brilliant. Plz make electric mop or diy marble polish machine

Sir,
Which wire i have to connect in micro usb port...?

[Ronit]

Sir...in which point of micro usb i have to connect red n black wire

[immrnoidall]

cells in parallel all need fuses in any size power bank to really be safe. but the scariest thing here is he did not insulate the negative shell of the cells on the positive end by using those little cardboard rings you see on every cell of a pack. Then he heated the metal positive bus bar right on top of the negative part of the positive ends of his pack. then hit the pack with more heat again, when shrink wrapping it. YES the positive end of an 18650, has a positive and a negative surface. the negative surface of the outer shell, in only insulated with the shrink tube. And that melts with low heat. if his bus-bar heats up for whatever reason like unfused damaged cell or board malfunction, and we could be talking about a blow torch type fire. you can get 200 of those tiny cell fuses for $7. THERE IS ALSO FUSE WIRE. Any paper can be used under the bus-bar to protect that negative edge of the cell's positive end. some cells have the paper/cardboard insulation ring under the shrink tube of the cell. look at them closely or just add something anyway.

First nice video, thanks then,
How to soldering latest mobile battery led lights or any other device, old type mobile battery is easy to soldering,

Thanks to your video, I find out when I want to see the current level of charge of a 3.7V battery I need to press and hold the switch, and when I want to turn off I hold the same switch. When you want to turn on the white LED, you have to double-click the switch to light the white LED.

I have the very same pb module but it cutoffs the battery at around 3.2V at discharge. Any fix for this or is the module 'bad' in some way? Btw both usbs give the same 1.45A

[valcesar]

How do you connect the stepdown do the powevank module

[paveljelinek]

Usb tester??? Name??? Brand??? Link??? It's nice and simple looking plus i like it's display alot edit: nooo, man, you're wasting power by connecting that stepdown board to mUSB!!! That way you're transforming power from the FVP 2times! You should use a charger board without mUSB that takes 5-15V input and charges the batteries directly, that way is far more efficient, your FVPs are too weak to afford this efficiency loss! Edit: did you connect those FVPs in series or in parallel? I suggest you go with series, that way you'll be able to bump voltage so even in low light you'll get some juice

Vai 400ma 5v solar energy se keya 8000mah li. Iion battery charge ho paye ga. 100%sheore dhup me 1%vi battery nehi barega..
