How long does it take to charge and should the unit be turned off or on during charging?

I charged it only once, with the unit off, until the light turned green. I have used it for 40, plus, youtube videos, and it is fine. I love it, its so handy, I just hook it to the back of my pocket, and I am good to go.

While charging the charge light changes color. I start the QFX charging the night before I am going to use it the next day. When fully charged, I have had it running all day 7 - 8 hours. I charge it again before I put it away. Interruption in charging should not hurt the QFX; just start charging again.

I think it takes about 3 hours to charge fully... or at least that's what I always do. I use the speaker part sometimes to hook up my mp3 player, and when I do that I have it plugged in. It is not the best quality for this though.

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.

Charge takes quite a long time before it turns on....this unit is as slow as molasses in January. Good luck

Probably around six or so hours. If the battery is not fully discharged it could be less. Will stop blinking when charged. It does not hurt to leave it it the charger like older batteries. If the battery is hot when put into the charger a red light will come on. Will not start charging until the battery cools some

This unit stays powered for approximately 5 hours on an ongoing basis when fully charged. However, it is VERY difficult to tell when it has (finally) fully charged. It takes forever.

How long should it take to charge this unit once it is completely drained?Unit has only been used once. Charging seesm to be taking an abnormally long time. (8 hours?)

It took approx. 1.5hr to fully charge. There is an indicator light that will turn from Red to Green when the battery is fully charged. Hope this helps!

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

Specifically, I don't know how long, but, the cool thing about this charger is it turns off when it's fully charged, that is, the lights don't flash any more. So, plug it in to charge, and lights flash on and off when charging --- when they stop flashing, it's done. Usually about an hour or so when fully dead. Also, leaving it plugged into the wall overnight hasn't affected it in any way. Hope that helps.

The unit does not need to be turned on. When plugged into a device it comes on automatic. You can charge it any time. I wait until its depleted an than charge it.

I think forty minutes would be plenty of time for it to charge enough for use. You can use it while charging it but it will charge faster if it is turned off. I hope you are as pleased with the replacement cord as we were. Our computer was old but still works well and is less complicated than some of the more modern operating systems. The replacement cord worked as well as the original but it didn't light up like the original did.

I get between 3-4 hours on a charge. I tend to charge it when I am at 1/2 charge while I am still on it to keep it ready to go. It works well,I am pleased with it.

It depends on how low the battery level is. If you are charging it from 0 then it will take about 1.5-2 hours.

Mine takes a long time to come to a full charge. Several hours. So as a matter of course, I usually leave it plugged in and charging, until I want to take it somewhere untethered. It does provide a long play time (8-12 hrs). Although that time seems about the same, whether it's playing, or just in standby mode, switched off. Which is why I leave it plugged in/charging.

Depends on how much is left in the battery. I just let it charge overnight, I have never timed the charge, but I would assume at least 4 hours from a full discharge.

Plug it up to charge. You will see the back lit light comes on and the graph that shows it is charging, and it does beep. This unit will stop charging once the charge is complete. Mine took about 26 hrs. to fully charge. Try letting it charge for a few hours, could be that your unit came without any charge.

two hours, depend of charger amp. Red light during charge and turn off when fully charged.

It probably took about two hours for the battery to fully charge. I have used it off-and-on for maybe an hour a night for two weeks. The battery is still going strong. The unit goes to sleep after 15 minutes of non-use to save battery. Hope that helps.
