Can the device charge and discharge at the same time?

No. There is only one USB port used for both input (charging internal batteries) and output (charging external USB device). You press the power button to select who mode it is in: Red for input, Blue for output.

The unit will charge or discharge depending on what it is connected to. If it is connected to a device requiring power, then the batteries supply power to that device. If it is connected to a power source, it will draw power from the source to recharge the batteries (I'm assuming you are using rechargable batteries). For example, I have a portable MP3 player / remote speaker which has its own battery, but its battery lasts only an hour. Using the PortaPower, it will run all night. The MP3 player is not a power source itself despite having its own battery.

The device needs to be charged when it has exhausted its ability to charge. It can be recharged multiple times without any loss of efficiency.

yes you can . but theres a power button next to each one . and you have to make sure you hit it and its going to show a blue light . even while its charging theres a blue light . but the end of the usb part has to be plugged into something so your several devices may all work at the same time .

I can charge one at a time with the attachments provived.But I wonder if you can use a y-connector type device at the larger usb end

Hi James, Thank you for you inquiry! Yes, you can both draw power and recharge the unit at the same time. Please let us know if you have any additional questions. Best regards, Earthtech Products

No. But it is best practice to only charge a phone when it has lees than 20% battery. Yes you can use the device and charge at the same time.

Yes, I keep reading that in a lot of reviews. But I'd still like to know if it is operable while it charges.

A mophie can charge them both at the same time and I heard it's bad to separate the two charging ports and charge separately

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.

Yes you can use it while charging, this is my third one, can't remember the others names but they were pos. This one is the best by far.

I just did a quick test: it can charge and record at the same time, at least with the USB cable mine came with. But, here's the trick: I was only able to get it to do this by flipping the switch first, and then plugging the cable in. The camera will continue recording. Doing the reverse order does not result in a recording.

Yes it charges both at the same time! It's a great docking station & sleek. If you shine a light in the space where the battery goes you can see where it attaches to the battery. I use it everywhere. I haven't had any problems with it. It's a great buy.

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!

it charges both at the same time:) and it will stop charging one once it's full.
