Do you have to do anything special to use it for the first time? After charging 16hrs it won't turn on.

If it's not turning on after 16 hours, chances are it's defective. If it was charging, the handle should be ever so slightly warm, indicating that the battery was charging. If that's the case, then it may be a bad switch. Either way, it needs to be returned & replaced.

You should not have to charge it that long.There must be a proablem with it.2 hrs worked with mine.Try another plug otherwise send it back

No. I did not have any problems. But make sure the brush head is on. If it is not pushed in correctly it will not work.

I think I had the same issue. We used all the charge (drained) then let it fully charge. I believe the first time took approximately 12-16 hours. It does not charge quickly.

Make sure you're using the input USB. Should charge automatically. You only have to turn the power on to use the device for charging purposes.

Charge the unit for a few hours then hit the power button- 1st charge takes some time

all you do is turn it on and hit the button on the side. If that doesn't work, try charging it for a while and if that doesn't work then you may want to call where it was purchased

I'd give it a few hours plugged in time to charge the battery. If that doesn't work, I suppose it's defective.

You have to fully charge it via the USB cable before you use it. Once it's charged the indicator light will come on. If it doesn't. There may be something wrong with the charger

I charged it for 24 hours and it never worked...you have to put one end of the USB into charger and one end into plug then plug it in to an outlet....

Supposedly you plug it in. Mine charged once, then never charged again. Good luck....

I can't find it in the manual but I would charge it for a couple of hours first thingout of the box. That's what I did.

The instructions tell you how long to charge it initially. I've only recharged it once since then.

I used a charger (my iPhone) to charge it the first time, never ever after that, I could've used a computer's USB port too, but that was it for one time, it's hand cranking or Sun light niw

Mine was working immediately after charging. You might need to replace yours.

Make sure the battery is connected properly in the back. Make sure the battery is also charged. And press the button on the battery pack in the back to turn it on

Mine turned on the first time just fine, but after that it had to be plugged into a computer in order to be turned on regardless of charge status. I sent it back because of that.

Did you fully charge it when it arrived? I's call customer service and if they give you the run around I'd return it.
