Several questions but have to ask separately due to character limits! Can you charge a device or devices from the USB ports while the battery pack is charging?

I use it to charge my iphone from the 1.0A port all the time and it works fine, but it probably wouldn't work as well with the 2.1A port since charging input is only 1.0A

You can charge up to 2 devices while charging the battery pack. The charger uses a microusb port on the side (microusb cable and charger to electrical outlet not included) whereas the 2 standard usb ports on the top are for charging different devices. I used a iPad charger with microusb and didnt have any issues charging 2 iPhones 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.

Yes you can. It takes awhile to charge unit but charges others 5x before unit needs charge.

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

Hi Peter Yes, you are quite right. I hadn't tried that but my unit will not do both at the same time. In practice I have a dual USB charger so the need has never arisen. Regards Richard Allan.

I just tried out both methods, and neither of them were able to charge any of my usb devices. This is mainly to create more usb ports for your computer

yes you can, but I have only done it on USB 2.0 or a usb wall charger of at least 1.0 amps.

No, the USB cable is use for data purposes only and is not directly connected to the battery so it can't charge it.

Yes you can. the USB charger also acts as a connection for the device. You could also look into a USB Blootooth Adapter. Hope this answers your question.

I charge it with the usb. It doesn't last long. I am going to return it. Doesn't really work good if needed while out.

Besides the two USB ports you have a micro-usb port. Use that to plug into a power source to charge your battery pack.

yes, you can use USB to charge. I suggest checking the manual for best guidance

No. You can't use it while charging the battery... you need to put the headset in the dock to charge.

I haven't tried a battery pack, but I've plugged it into my laptop (via USB) and a wall outlet (via USB / wall adapter) and it charges just fine. I'm sure a battery pack will work too.

I'm actually using a spare one for that function now. HOWEVER, it will only charge items at the USB limit of 500mA per port. Most true chargers are capable of 700mA to 1000mA depending on the device.

Thank you so much for the explanation! I was worried that the USB is only for file transfer but not for charging battery, but this answered my questions!

If there is, it's by no means accessible to the average consumer. The clear answer is no.You can charge this through its micro usb port and then have it ready to power an electronic off the (full-size) usb slot when needed on the go. If it dies, you get a new one. If that's a concern then get a better, more expensive one.

Yes, You can charge this device via USB port from your laptop/desktop. First time takes 3 hours for full charge.

The way it comes out of the box you halve to charge with the USB. You can buy a charging adapter from Amazon. I had a suitable charger that has the same wattage, so I didn't buy one. Either way of charging works great.
