    The product is easy to use and clear at a glance.
    Packed in a package with zip fastener. On the back is a brief description of the functions. Put on charging smart shows 1 time per sec current measurements (voltage, current, temperature of the device itself, and counters: time after switching on, passed through it power, in watts, watt-hours, milliampere-hours) by pressing reset-reset all the counters and starts again.

    I like the timing feature
    A wonderful tester, all the readings are quite accurate and in the subject. The only downside is the weak brightness of the indication, especially in bright light. (when measuring power from the solar panel, this is especially relevant) Otherwise, a useful thing is definitely. I order the second time. Seller thanks!

    The product corresponds to the description for all 100%.
    Very necessary thing. Long wanted to order. Took under testing charge on the phone bought on ali to check quick charge 3.0 or not. In general, a very necessary thing everywhere can be checked how the usb port works (missed or not). Seller thanks details in the photo.

    An unexpected feature
    Going back to read the description, I found it does say "can be powered down to save data".
    What this really means is that you can plug it in between a power bank battery and a device, flatten the battery while charging the device, then plug this meter into a second power source to read the results for how much power was used.
