Description
handy USB current tester from the Keweisi brand and the KWS-V20 type.
You can see, among other things, the voltage and the number of A.
Useful to gain insight into what a USB device consumes, but also whether, for example, you are asking too much of your USB port with an Arduino or ESP8266 (or are getting too little for your relay, for example).
Voltage: 4-20V +/- 1% Load: 0-3A +/- 1%
Dimensions Length: 7.3cm Width: 2.5cm Height: 1.35cm
