can I turn on the heat function while charging?

The instructions say no. For safety reasons, the hand warmer function is disabled anytime the external battery is being recharged of charging a device.

Charge it for a while and then try to use it. You can use it while it is plugged up

No. In fact if you plug it in to charge while on, it will shut them off to charge.

mine has gotten quite warm. I don't use it longer than necessary - only in emergencies, not as a substitute for a regular charge. I'd be careful where you place it while charging.

You can, but its a slower charger so you would need to leave it on all the time but it will work

You can turn the video screen off on the charger. Once you hear a noise, you can quickly switch it back on.

Should not be problem. There is a switch to turn the heat on/off. If that is what you are referring to.

No, there is no On/Off button. The red button when pressed causes the lights to display charge status.

Nah, it is just drawing the amprage needed to charge. It shouldn't get much hotter than that... If it starts to Burn to the touch there may be a defect in the product. But hot to the touch just don't lay on it for long periods of time or anything.

Didn't try that myself, but it worked when I plugged it in. Use it while it charges...

You can do this manually from the touch screen. Might also be able to program one of the periods to just fan without heat or cool but have not tried.

Yes, you can use it while it is charging. This is important if you forget to plug it in so it still works.

Have you tried pushing the heat switch on the back of the unit to the "on" position?

Yes. It automatically turns on once plugged in, but can be shut off while charging.

It does warm up a little when a device is charging, but nothing significant

If you plug it into a computer that is on, not in sleep mode, it should start charging right away. No tricks.

I have four different wireless chargers, including this one. The phone/tablet gets slightly (and equally) warm on all of them. However, if you allow the phone/tablet to "daydream" (display clock or other graphic of choice) while wireless charging the phone/tablet gets very warm, even hot. I find this to be equal on all chargers as well. I always push the power button after the phone/tablet starts charging. This stops the dream mode. Also you can disable dream mode in the display settings. I like this particular charger because it's easy to line up the coils and the green/red/blue light is visible from top, end and sides. Bottom line is if your phone/tablet is active while charging, it will get hot. The charger itself doesn't cause the heat.
