- I got a good price for this unit, 3.46 USD on flash sale. I chose this device over others because it also measured the capacity, not just volts and amps. It's pretty straight forward: you place this between the two devices where you want to measure the current flow. For measuring capacity, you need to keep this connected the whole time the battery charges (or the powerbank discharges). The little button helps you reset the time and capacity measurement. I have only one concern regarding this device (hence the 4 stars): the display and all the electronics soldered to it rattle inside the casing, because it appears it wasn't fixed in place before the case itself was sealed shut. This may put extra strain on the wires every time I pull out the USB plug and may shorten the lifespan of the entire unit. If the wires going out have a few extra loops inside the casing, then it's all good. Check out my comments section on the youtube video for later updates about how it holds up. This unit had the best price in its range and it is the main reason why I chose it.

- Works excellent for testing capacity of cellphone batteries. Just run your phone totally down then fully charge it through the tester. when fully charged read the mAh on the tester. That is the actual capacity of the battery. As the battery ages this number will fall.The back of my case says KCX_-17 input rating 4-30v/50ma-3000ma This is more than stated in the GB description.A very excellent device!!!Herby Ordered a spare

- Прибор работает, данные показывает. Можно проверить все свои usb зарядки, и не только, на корректность выдаваемой напруги. Корпус хлипкий, плата внутри болтается, не сильно критично, но не приятно.
