🔋 LHIABNN DIY Power Bank: Build Your Own External Battery Pack with 2 Output and 3 Input (Micro, Type C, Lightning) - 18650 Battery Not Included Review

It's great. You have to apply the same voltages if it's a voltage difference let's say you apply 7 3.6v and a 415v, 7 3.6v literally attack the 415 and drain it at very high amps what can lead to a collapse since everything is parallel

So far so good. I use these chargers not only as a power bank, but also as a charger and case for my vape batteries. Had to be modified to make it easier to open. Simply cut the clips at the ends leaving 2 clips on one side and 1 clip on the other. It worked perfectly.

If you like to build your own backpack, this will help. Follow the instructions, especially when inserting the batteries into the case. It is not meant to be opened/reopened. If you put the cover on the case, you will notice that it cannot be opened without effort.

I pulled a bunch of flat top 18650s out of some dead laptop batteries and put them in this case for fun and used as a proof of concept before i built my own. It worked great for a day or two and then stopped working. Either my charger was too powerful or the electronics in this thing had failed.

Remember that it is not intended to remove the batteries once sealed, it is not a box. But for those of you who want really good power delivery without breaking the bank, this is the device.

Received yesterday, opened today. The quality is better than expected, all made of Chinese plastic. The board works, everything looks fine. The clamshell took a bit of fiddling, I'd recommend a small flat head screwdriver to push in the goodies that get stuck. Remember that once reassembled, a few special SlimJim tools are required to disassemble the plastic clamshell. It seems possible to do this, but it will take a lot of effort to do it without breaking. After you have installed all your…

Update: Please don't waste your money on this junk piece of counterfeit device. I have a battery full of 18650s and it doesn't even charge my tablet to 100%. My tablet with a very low battery (i.e. doesn't take long to charge) went down to 60% and battery down to 10%. 90% of the battery charged my dead battery on the tablet to 60%. This is an outrageous and counterfeit device! There is too much loss in the circuit or something. It was also charged for FOREVER and discharged even faster. As. It…
