Interesting product. I use it for load testing USB power supplies
when I am selecting the latest and greatest for the Raspberry Pi 2's I sell.
In conjunction with a voltage/current analysis device, its the perfect addition
to determining how well your power supply is performing.
I have also used it in a custom circuit to test the discharge characteristics
of rechargeable batteries, allowing me to select the best at a reasonably price.
