Charge your batters and see the capactity
Tested it and its very accurate. It clearly shows the voltage and current being supplied to your mobile device or similar when its on charge. See the mAmpHr used to recharge the battery allows you to keep track of the battery condition. Also has 10 storage locations which is useful for your many devices that need to be recharged. Very handy diagnostic tool to tell if your mobile or portable device is actually charging correctly.Tested it and its very accurate.

Good product if you know how to use it.
Good product, but requires a bit of knowledge to interpret the capacity measurements. The device measures the current passing through it at a current voltage (usually 5V for USB). However, most of Li-Ion batteries voltages are 3.6-3.7V. Hence, inside the battery charger controller the voltage is converted from 5V to 3.7V (or a bit more) when charging the battery and the current is increased. When the battery is discharged the opposite conversion takes place: 3.7V is converted to 5V and the output current is decreased. For instance, 1A at 5V is converted to ~1.38A at 3.7V (this figure can be a bit different depending on the efficiency of the converter, battery type, cables etc). The thing is that the number of mAh displayed at the end of the measurement indicates the current at 5V, but it ...

The thing is that the number of mAh displayed at the end of the measurement indicates the current at 5V, but it actually is converted from 3.7V. Therefore, to find out the Li-Ion battery capacity the mAh measurement has to be multiplied by the coefficient 1.38 (or a bit less, but usually not much less than 1.30). It took me a while to figure out how to interpret the results, but once I figured it out the readings are consistent with the nominal capacities of batteries I have.

What a brilliant gadget!
If you’ve ever wondered what current is actually being supplied to your USB devices, you need one of these. It’s small and has a nice clear display. Not only have I recommended it to a like-minded friend, I purchased a second one for him.

Very useful simple tool
Great to be able to check if your device is actually taking the input it's supposed to. I found my Samsung s8 was only taking 2000ma even with a new battery

Recommended, works well and better than most of its competitors
Works well, useful max Ah capacity, even when the display reaches max Ah, it keeps charging (most of the others stop).
