4x18650 Battery Charge Storage Box 5V 2A Dual USB Type C DIY Power Bank Case Charging Case for 4x18650 Li-ion Batteries

Works well but only USB-A is output, has microUSB and typeC but those only charge the device and do not output current. Strange, I though USB typeC would also be able to charge other devices but guess not

Does not contain 18650 batteries The support is smaller!!

The device works, for testing I installed one battery, it charges itself and charges the phone, shows percentages. In general, everything is in order.

At first glance, everything is fine, the LED is lit, the display shows percentages quality, and that's all. !!! Does not charge Does not charge the phone

Inserted batteries, it accepts charge and charges the phone. Shows the charge level. Corresponds to the description.

Only batteries without a "nipple" are suitable. 1 port does not want to charge.

Satisfied with the goods and service. I recommend the seller.
