not sure - but I will tell you I was very disappointed with this device and used it only a short time before I had to buy a different MP3 player...

A few hours. A red light should come on when you plug it in to indicate it's charging and will go off when it's fully charged.

I'll guess a few hours, if you use it a lot. I keep mine sitting in the charger all the time, though.

Same way you charge your phone, from a computer or a standard USB charger. There is a mini usb input port for that and the unit comes with the USB cable. I believe it takes 2 hours for a full charge from empty.

Yes, it does it in about 25-30 min. Charges up to three devices before needing recharge. Love this charger. Works well

At least two weeks. I once charged it fully, unplugged it, put it in my backpack, and did not use it for about two weeks, and it seemed to have maintained its full charge even after that whole time not being used. Just remember not to have anything plugged into the USB port when it's not in use, otherwise it will drain all of its power by itself (keep it unplugged unless you want to charge your device).

Not long, haven't timed it. Plugged in to 12V charging system, it seemed to charge quickly.

depends. I charge mine on airplane mode and it took an hour I've also been using it as it charged as I run my own business and it took a little less than an hour and 45 minutes

Not sure. It was a gift to my grandson, but I've heard no complaints about charging time.My experience in general is that charging thru USB is much slower than conventional AC charging.Doesn't the instruction sheet tell how long it should take to charge?

It doesn't take long... just about as much time as your cell... It is best to turn off any device while charging for faster time. I plug my unit in at night and charge while I'm sleep... since I only use in the mornings! Very neat with great sound... more than you really need in an average crowd.

From zero, takes about 12 hours. When you have about 25% left (which is what I have after a weekend of traveling), 6-8 hours. That is with it hooked up to my PC via USB. Not sure if you plugged it into the wall.

It usually takes around five to ten hours depending on the device that you are trying to charge.

I don't remember how long it took to charge but you can use it while plugged in since it is battery or direct current. I stopped using mine since it did not work properly.

Do you mean how long does it take to charge? But the hours it last is until you unplug it.

As per the instructions you charge it for 12 hours then totally drain the battery 10 to 12 times. Not do it once. It has to do with battery memory. Also use a full 110 wall charger for charging and not a weak USB port to charge.

In my experience it depends on how far it has been discharged. The times I have needed to fully charge it, it usually takes about 2-3 hours.

I actually don't know how long it takes - I usually just plug it in over night and it's charged by morning.
