USB Tester for Voltage and Current
Test the USB output off any device with a USB port
Small, simple and extremely easy to use. Just plug the USB tester in to any USB a port and receive a real time voltage readout. Connect a device to the USB tester output to help monitor the voltage and current flowing out of the socket. The single LED segmented read out will switch between the voltage out and the current out every 5 seconds, eliminating any need to manually switch between either factor being tested.
Great for an array of products, from USB outputs off a PC, laptop, power supply, home charger, car charger and mobile battery banks to monitor the consumption of a smartphone, tablet, PC perpherials or any USB powered or rechargeable device.
Also great for projects and prototyping to ensure all things power out of a USB socket is what it should be, before connecting to any important device.
Voltage Input/Ouput: 3.5-7V (+/-1%)
