Can the device charge itself and at least one other device through its USB output ports simultaneously?

I have to disagree with the posts here. Yes, you can but only under certain conditions. If you are hooked into your computer USB port to charge the battery pack, then no, it won't. However, if you are plugged into a higher amperage charger ( I use my 2.1 amp Samsung tablet charger) then yes, it will power both ports and charge. I have run my tablet and my Galaxy 3 phone off of it while having the battery pack plugged into my tablet charger and it worked just fine. Started at 43% charge on the battery pack, charged both the tablet and phone to 100% and unplugged at 63%. I'm sure it would have continued to go up if I had left it on but I was at work and had to move to another department. I have to disagree with the posts here.

I tried this and it did not work. I'm not sure what "smart" charging means, but this device charged my phone for a while and then turned off (or the phone turned itself off). The result is that if I leave it connected, I end up with a discharged phone. Not good.

I am able to charge my phone and tablet from this device when it is plugged into an outlet. However, it charges itself very slowly and never reached full charge, so my copy may be a dud.

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

Short answer, no it can't. Even the other brands of similar devices are unable to do this effectively. It may be because the charge rates for these products themselves is only rated at 1A.

My RAVPower will NOT charge while it is also being charged. I had to make a special cable to test this when I noticed it. The output voltage drops from 5V to 4V, and the output current goes to zero, or very low. Because a voltage is still present many devices think they are still being charged, but in fact they are not.

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

I tried charging two at once and it didn't work. I think what was really intended is the one mini/micro whatever it is connection on the face is the only charging connection... On the positives, its a neat little device and I do mean little, the power adapter is much bigger than the hub.. I would still recommend buying it just based off its overall size and portability, I just kind of like the thing... Sorry no I dont think its capable of charging two devices at once.

Not when the pocket port is completely dead but once it has at least 1 bar of power then yes you can charge both at the same time.

This device can be used to charge 2 phones at the same time. It states that it can charge a phone and an iPad at the same time to describe the amount of output the device has but 2 phones will charge just fine.

No, it only has a single qi charging coil, so you can only charge one device at a time.

I have been able to charge two android devices simultaneously. If course, the rate of charge decreases with two devices.

I believe you can. The USB hub splits the power and therefore it will probably take longer to charge both devices simultaneously. However, it should work. My opinion is based on powering a printer and a external disc drive using the Hub with no noticeable loss of function.

Unfortunately you already answered this question. Yes, it will require two separate ports to power this device.

It has a usb port for charging devices, but cannot itself be charged through that port.

yes it does - comes with one USB port and another input that includes a cord to convert it to usb - so it can charge two devices at once. :)

Yes, with two USB cords you can charge both devices. I personally wouldn't expect to get to 100% charge for both, though.

It charges itself by a mini USB and charges other devices the same way. You might be able to find an adaptor if you need something else. I have not been impressed by its capacity.

Hello, yes you can charge 2 devices simultaneously. If you only use the blue 2.1A output, then the output current is 2.1A; and if you only use the 1A output, then the output current is 1A; if you charge 2 devices simultaneously, the total output is 2.1A.

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.

The specs provide the information you are asking. It provides 2.1A per port simultaneously which is enough to charge two ipads at the same time as quickly as if you were using two individual ipad chargers. In practice, it seems to work as advertised although I don't have any way of measuring the output while both units are charging.

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

This is what this device is designed for - 2 USB ports give extra power to 1 device.
