Excellent USB measuring tool. Can measure voltage (V), current (A), power (W), energy (mAh, mWh), temperature (degrees C/F). Can even detect if USB can do fast charging! Came in a high quality plastic case, with padding inside to protect it (see attached photos). Highly recommended product. Very fast delivery to Greece, using Priority Direct Mail (PDM). Thank you very much, Banggood!

This is an improved version of the classical power meter for USB. It gives you mA resolution, in the previous versions you oly cansee tenths of miliamperes Also there is an OLED display with 4 colors, more visibility. Also it gives volts, mAh, temperature.... Very useful device ...
