Is it possible to charge the power bank and have the USB draw power from it at the same time?

I do not know for certain, but i belive you might be able to do that , but it would most likely keep the power pack on a low battery until you let it charge without draining it at the same time. I hope that helps

Yes. I was just charging the power bank with a USB cord from my wall outlet and then another mini USB connected from the power bank to my Galaxy S3. It worked great. I think the charging time is slower but I did this overnight while I was sleeping so I'm not certain. By the morning both the power bank and my phone were fully charged.

Yes. I have had it plugged into a wall outlet and used the charger at the same time.

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.

No, this is only for usb devices. They make separate power banks for pc's there alot larger though.

yes it can work and charge at same time. charging it requires powered usb port. you can get a usb port for charging that connects to wall outlet if you don't have a nearby powered usb port.

Nope. Looks like the USB ports are not powered while in recharge mode, even though the recharge port is dedicated to recharging.

YES. I specifically bought this so that I could charge while using line-output to speakers. So yes, it will charge and function simultaneously while connected to usb power.

Yes, but you need to have two open usb ports, one of them usb 3.0, with the power being plugged into the usb 3.0. USB 2 doesn't provide enough power.

Yes. I use a charger that works via AC inlet, and I can use it at the same time. Never charged my unit via usb into computer though and tried to use it at the same time.

Yes you can use it while charging, but it can only be charged via USB cord.

Yes. Plug usb into car/computer and other end into power bank to charge. Then to charge phone put usb into power bank and other end into phone

You cannot when charging from a computer (that's all I use, so I assumed....). But from external power source it looks to be a yes. (sorry folks)

I think you might possibly be able to connect then together using a usb hub with multiple alternative usb connectors to get a stronger current, unless they have an in-built system to specifically prevent this.

Yes you can charge them both at the same time but it's very slow. It took over 24 hours to charge my S3 batteries. Also very cheaply made, I broke it before i even got it out of the box. Had to use duct tape. I do not recommend this product at all. UBOC is much better

Yea it comes with a regular usb cable to mini usb. The mini USb side charges the unit. You can't charge your phone on it if that's what you're asking. No 'power bank'

Yes you can. You have 2 USB ports (1) has a 1amp port the (2) has 2.1amp port as you know the 2.1amp will charge faster.

The way I've done it is just plug a USB cord into each of the two ports. One USB is a higher charging power than the other. I've had good luck charging two things at once.
