Powerbank case from AliExpress. Let's build a powerful power bank from 18650 batteries.
I ordered a power bank case from AliExpress in China. In today's video, we'll build a powerful power bank from used 18650 batteries. I'll also show you how to test them upon receipt. Overall, I got a very powerful power bank for a low price.
