can you charge another device through this while it is charging?

Yes! It doesn't charge as fast but you can charge and use with no problems. This was a great purchase for us.

I have and it worked, don't know how it affects the charging of the Poweradd though.

I would suppose you could since the charging is through its own port leaving the two full-sized USB ports open. Haven't had this long - but it is extremely fast - charged my phone in 15 minutes. seems to be a good product and has slick metal case.

You can use both ports ... I have had 2 phones charging before at the same time

most certainly! I have had two devices charging at the same time with no problem. Certainly one item charges faster but all in all the charger is real quick on recharges and you shouldn't have a problem good luck!

Hi PeterYes, 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.

That is an interesting proposal of using a charged battery in the charger to try to charge another device using the attached USB port. I have never tried it. Reviewing the manual, it only talks about using the USB port as a power source from computer to charge the battery in the charger but not the other way round. Do not know the answer. You may call Anker yourself. 1 800 988 7973

Yes, you can charge two USB devices at once. If you have enough cables I do not see why you could not do pass through charging as well.

You could but I charge them together, once the phone is charged the battery on the charger starts charging.

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

Yes. You can charge 2 USB devices and 3 electrical devices at the same time.

Yes you can. So far I've had this device for 3 months now and it's still charging good. I use it for my iPhone 5 and iPads.

I can only think of one reason why you would want to charge this and another device at the same time by using this device. When you do that, it charges very slowly, or not at all, depending on the power absorbed by the other device.

Yes, I can! I even can charge full my ipad 2, and still have some energy to charge any other device. And It doesn't get hot when charging. Hope this result usefull for You... And sorry... I'm just learning english...

Yes, you can. As a matter of fact, you can connect the phone USB end to the charger itself while the other battery is on the charger.

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

No, this will not allow you to do that. The secondary USB connection is wired for power only, and in any case what you are describing is not possible with any cable, because USB communication is bidirectional.

Yes you can. I bought a couple of these chargers. I have an iPhone 5 and the original iPad. I use this to charge them both. The other charger is in the family room where we charge iPads, touches, iPhone4's, pretty much anything that can be charged through a USB. Works great.

Yes it can. I little slower than your traditional charger but yes. That's what I use it for, charging multiple Apple products instead of plugging 2 different chargers.
