Can I use both ports to charge devices, or I have to use one or the other one at a time?

You have to use one port per time, those two ports are for different speed.

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

the way i see it if you only use one port at a time you get full power. 1/2-power when both in use.

Hello Tim. The USB ports can be used for charging one 2.1Amps device or two 1Amp devices.

Should work just fine... plus you can charge your usb devices at the same time.

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

You can use either one, also the 2nd one can be used to extend power to another device.

The charger has two usb ports, a usb2 and a usb. I see no reason you should not be able to charge two at once though I have an iPhone 4. That charges quite quickly.

You need to plug both in because one transfers data and the other supplies power. If you can only connect one then you need a usb splitter.

Two devices can be plugged in at once. One in the 1A port (like a phone, camera, etc) and one in the 2A port (like a tablet, or other device). Tablets will not charge off of the 1A port, but phones and other low-draw devices can charge off of both ports.

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

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

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.

Yes in fact you can use it as a charging port for your devices. I went on a road trip and used it to charge multiple devices simultaneously. It does not matter if the devices are Apple or not, they their own charger but the other end is a regular usb plug.

Yes.....you can use both outlets when the 4 ports is plugged....really good product.

As long as both have USB cords that can plug into the connector, than yes, you can charge both.

No, the most you get from each individual port is 2.4 amps. Or the 4.2 amps using both at the same time.

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