Thank you for writing in.
Could you please tell us your order ID or the link of the product so that we can ensure which product you are referring to?
It is better that you can tell us more details of your operation, such as input voltage/current, the load, the wiring, the working environment.
If you can, we sincerely hope that you can send us some images to let us check the problem details.
With your help, we can find a solution more quickly.
You can send this information to us by email (service at droking dot com ).
Looking forward to hearing from you.
Best regardsNomad

https://www.amazon.com/gp/product/B01D8GEDQ4/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1I’m charging a Moto E 2nd Gen. phone with a 2390mAh battery.
When charging, voltage stays consistent @ 5.1V and starts @ 1.05A. Of course, as the phone charges the charge current slowly decreases until full charge. It then maintains between about .01mAh and .1mAh trickle charge.
After charging for awhile, when I go to sleep at night the “C” reading shows around 800-900 mAh. When I awake in the morning the “C” reading is 60mAh – 90mAh. This has happened two nights in a row.
I have the DROK USB tester set to switch between displaying Voltage/Current and “C” cumulative charge. Four button pushes to get to that mode I think.
Both the cable and charger are new, purchased last week.
Again, thanks for the reply. Please feel happy to contact me by email if you wish.

I plugged the USB meter into a different port on the charger and there were no problems. The “C” reading did not reset overnight.
So the problem might be with the charger, not with the meter. I’ll post again if the problem occurs again.
Again, thanks for your assistance.

February 13, 2017 at 3:58 pmPost count: 0I have the same LED Dual-display USB 2.0 Digital Multi-meter Voltage Current Capacitance Testing. I bought it either in 2016 or 2015. More than likely, I bough it in the former. It does not move from the Voltage-Ampere setting. I press the testing button and there is no movement in data. I want to keep the meter. Do I have to keep my hand on the button for a specific amount of time. I use is for a Vinsic 22Watt Solar Panel. The panel did not come with a charge controller. I like to know when it is ideal to charge my mobile phone. Thank you.
Sincerely,
Brandon Keith McCormick
