Excellent product. I like the switch-ability and ease of use. This device allows me to test my battery packs and charging devices so easily. Very happy and will be ordering another one soon.

superb product. works well for testing these kinds of readouts. combine switches to get different loads!

The bigger version of USB load tester. It is good for testing chargers with qc2.0 protocol. 9V and 12V.

These puppies get quite hot. Will be adding a fan. Fan Connector is provided . Good Deal.
