I purchased this charger to replace a lost charger for a Coby MID7048 tablet.  When I plugged the charger into the tablet and the wall it began charging.  When I checked the charger a couple of hours later, it was not working.  Found an internal circuit breaker switch and reset it.  It began working again.  Checked a couple of hours later. . . .same problem.  Needed reset.  After resetting, it finally charged the battery and has been working since, as long as you don't let the tablet battery run down too low.  Apparently a very low battery will pull too much current for the charger and cause the internal circuit breaker to trip.  Resetting gets everything going again and once the battery gets enough charge, the charger will keep going until the battery is fully charged.

Worked fine the first time but now it just cuts out and stops after a few minutes. Even after charging for days.
UPDATE - turns out the charging cable was bad so i tried another one and it now charges and works fine.

It detects the qi charger at first and says its charging but when the screen turns off, it stops charging. I have checked the contacts multiple times and they are all touching the contacts on the phone. I am not sure what is wrong with it.

It does not keep charging. In fact, when I've come back in to the room I noticed that even though I didn't move it it didn't charge. It also wouldn't charge my phone with the case on it. Should have went with the Samsung wireless charger.

Fully charged but keeps turning off with no jostling or movement of the battery pack when I have something plugged in.

Do not know why, but just had this item for a month and it already started acting up. Seems like it has a loose connection and one little bump or I move it, it will stop charging.

Mine keeps turning off. Very frustrating. I would return it but I missed the window by the time I went to use it.
Revised review to 5 stars. If yours is turning off try changing the plug. Turned out my charging plug was defaulted not the charger.

I had the same problem as another client. My charger worked for a month and half maybe and then it stopped charging. I returned it and bought another charger through another seller, and now I'm in the same predicament. It's no longer charging either!!

It work just has to be seated perfect before charging starts. Also consider using alternate USB cable instead of the one that comes with purchase

Wireless charging seems to be defective.  I bought this item because it combines a USB hub with wireless charging which I intended for my S6.  The USB hub works fine for charging, but since I started using it several hours ago, the blue light (indicator for wireless charging) turned into a flashing green (or red - colorblind here) light and the wireless charging stops.  Not sure why but this has happened at least three times.  I had to unplug and plug it back in, and it will resume the blue light and wireless charging, only to happen again after a short time.

The attached photo shows the flashing light (trust me, it's flashing) when wireless charging stops.
