Product Description

The original KEWEISI Voltage, Curent, Power/Energy/Capacity USB Stick

Indispensable in the toolbox. Although it's USB, it can handle up to 9V. Just cobble together a USB breakout cable.

Plug it into a power source (powerbank, mobile phone, USB power supply etc..) and then connect a load to the other end of the Keweisi and it automatically displays voltage, current, elapsed time and power in mAh. All handled by an on-board microcontroller with 24C02S 256 byte EEPROM non-volatile memory

Reset button on the top (RTZ - return to zero).

Easy to adapt a USB cable to connect the Keweisi to non USB devices, but don't exceed the current & voltage limits:
