Excellent product, I will use it as a battery charger, but I also tested it to charge my cell phone and with a full charge of the power bank, it went from 0% to 61% on the cell phone. I found it perfect for emergencies.

The 18650 batteries that have been removed from the equipment that is being disposed of can be reused as is. Some knowledge of battery capacity measurement is required, but they are ideal for reusing 18650 batteries in good condition. It's nice that they can be reassembled later.
I havent gotten to use it yet i have to buy batteries for it but it came in perfect condition i hope it works.
I bought these as replacements for similar cases with micro USB. These cases have a type-C connector, which is a big plus.
Excellent case for building a power bank yourself, as can be seen from the images, the published technical data is correct, 5V 2A output and the same for input. As for durability, it's as good as other cases, it's better not to drop it on the ground. Satisfied with the purchase and I recommend it, I had bought others but none had these features. Excellent seller. Delivery in 12 days due to the Easter holidays.
