Hoco J100A-20000 (392420001)

An inexpensive portable battery that allows you to connect two gadgets at the same time and share accumulated energy reserves with them. To do this, the power bank was equipped with a pair of USB A connectors with standard output voltage and current parameters of 5 V / 2.1 A (10.5 W). But the model does not support fast charging. The lithium-polymer battery “under the hood” of the model is supposed to be charged via microUSB or USB type C ports.

Its “certificate” capacity reaches 20,000 mAh, but in fact the battery is capable of delivering about 11,800 mAh of real capacity to connected devices. This difference is caused by capacity losses when converting the operating voltage from 3.7 W at the battery terminals to 5 V on the USB bus. To roughly assess the remaining battery charge level, the Hoco J100A-20000 has four indicator lights. In general, the model is assembled in a plastic case with a thickness of 27 mm and a weight of about 400 g. The power bank is resistant to mechanical damage and temperature changes.
