DIY 8×18650 Battery Power Bank Case with Type-C

Delivery is fast. The product is in working condition. I ordered two pieces because there are a lot of cans at home from a broken power tool. When I inserted the batteries into the power bank, I managed to insert one battery the wrong way and the negative contact spring immediately burned out. I replaced the spring and it had no effect on its functionality. but be careful! The device cover closes with great difficulty and seems to be stuck permanently. It is most likely not possible to open it without causing damage. The charge level shows an approximate value, but I wasn't expecting anything more. Overall, I am very satisfied with the product.

The device is good and useful. For that price, it's quite good. But... When you open it again, the plastic locks break instantly. You need to think of something to prevent it from falling apart. That is, you put the batteries in once and forget about it until one of them dies and you need to replace it.

Works great, waiting for batteries. There were 2 pieces, checked them, everything is good. The only downside is that the case has snap closures, as many as 14 pieces. I liked the case, it's beautiful, but it arrived half closed. These closures won't last long.

interesting product, you won't be able to check without losing the functionality of the product, you'll have to trust the video.
