Can I charge it while it is charging other devices?

No it's best to charge it overnight before attaching devices to it to charge. Charges phone with no battery in an hour.

Yes, I regularly charge two devices simultaneously. Great little device, turns two wall plugs into three, plus the two USB ports as well, all active at the same time.

From what i can tell, no. you could however, use the attached charger on other devices that are compatible.

Yes. The device can not do two functions as the same time. It can either charge or be charged.

I can use mine while charging. The charge time varies depending on whether you are using it or not. It should be the same as your original charger.

Yes, you can. Unfortunately you can't close it while it's charging though. The screen is visible when charging.

I'm sure you can. I use it for all sorts of different devices. I have noticed that it may take longer to charge certain items than their own plugs may but I haven't found anything that didn't charge at all.

I've used it while it's charging. The cord is a pain while it's plugged in. But yes you can.

No, it can't. I tried, it keeps charging itself, but won't output anything while charging.

Sure. You can charge both of them at the same time. Or the pair of two other devices.

You probably can if you have the cords for the input and both outputs, but charging the battery pack is slower than charging a device from it. I charge my battery pack at night and then use it to recharge my devices when I am on the go or away from the house.

Yes, the names above the ports are just suggestions. You can charge whatever device you want in any slot. However the higher the number above the slot the faster it charges.

If your devices supports charging via USB port then sure you can charge all four at the same time.Charging time would be uneven though because current rating is different for two ports.

No, this charges it just as plugging it into your computer or wall/car adapter would. It will most likely charge faster if it's off, but you can definitely use it while charging.

Yes, it can charge both devices at the same time. I don't have any information, though, about charging rates in that situation.

As far as I can tell, you can charge anything that uses a USB charger. I have charges an iPad on it with no problem.

You can use it while charging, but it will slow the process. You may use more power to run the device than is going into the battery to recharge it.
