Will these work while charging the battery, when it's plugged into USB?

Yes, I have just verified that it does work in wireless mode while plugged in via USB to charge the battery.

You can keep them in the charger when not using them. Or, at least I do and they still work!

Nop! you won't be able to charge them via USB, because the charger it self does not have USB port.

No, it will not work while charging, after it is completely charged, I leave mine plugged in overnight, remove the cord and it should work perfectly.

Yes, most devices can be used while charging. You can also plug in the battery while charging a device and charge both at once.

They will, as long as the power source you are using has the minimum power necessary to feed the battery/charger and the female connector the battery/charger uses is USB 2.0 compatible. The mini plug on the cords is flat on one side and slightly rounded at the edges, not like the older USB mini connectors that have squared-off edges and a "tiered" look (smaller portion on top of the larger one).

You can not use them while they are charging. The charger goes into the phone jack. You cannot monitor them either. They are silent when charging whether they are on or off.

Yes, but they can be slightly discharged. It's best to charge them when they arrive. You won't do any harm because the charger is smart (unlike the old-school chargers, "dumb chargers," that used timed charging methods).

Mine work fine. Since the battery pack is long, they have to be the only thing plugged into the outlet. Hope this helps.

No these don't work that way, they aren't so much like a battery. they only out put power. They work very well even in not so great light. I do suggest getting the highest wattage you can afford. These will keep a phone or tablet charged with no problem, however, the device you are trying to charge need to be off for fastest charging. Hope this helps.

I charged mine for 24 hours before using them. They work great! I have noticed that when they are not plugged in they only stay charged a couple of hours.

Same as C F, after a while of using it while plugged in, the USB port has become a bit lose and it will mess up as you move around with the cable plugged in. So yeah, it will work while charging, but you will losen up your USB port and eventually, you won't be able to use it while charging.

Yes it will work, although I prefer to use a better charger! Just make sure that once the batteries are charged and the light on the USB goes out, disconnect the battery first, then the charger! Also when charging the battery, plug the charger in first, then connect the battery! Your battery will hold a full charge and last longer.

It will charge them. If you charge at same time it will take a little longer if it gets warm don't worry

Yes. Put them in a dumb charger for a few minutes and they will begin to take a charge. You can then put them back into your smart charger and they will charge.This works for most but not all batteries that fail.

Yes it works while charging. Make sure you have connected to the Bluetooth and then it should function without problem.

Works fine while plugged in. However, I'm not sure it is actually charging while working.
