Does this charge from AC plug or does it require USB connection?

It does require a USB connection, but it comes with a cable that has the audio jack and the USB input, so you can charge it while you download, or , there are A/C chargers and car chargers for USB.

The unit is charged via micro USB from an external source. (PC, AC Wall charger, etc...) I hope this helps to answer your question.

It has a USB port, but I am assuming it is to plug into the computer to charge things. I've only ever used it in a wall outlet.

Mine did not come with an A/C plug as the previous post says. Mine uses a USB cable - one end into the device and the other to a USB port on your computer. Doesn't take too long to charge up.

this is charged by a small USB cable which charges from your computer or a 110 v USB wall connection. I believe the cable comes with the unit to attach to your computer. The USB 110v plug is readily available and cheap

Single USB connection. It does not draw power from the computer. It has a plug for external power. I don't like the external drives that draw their power from the computer.

It's charged with a usb cable that's included. For faster charging you need to purchase usb a/c adapter.

It is powered by a proprietary AC adapter and cable. It is not USB powered, and has no USB ports.

Comes with USB which you can plug into your computer to charge. Otherwise you will have to buy a wall adapter to charge from an outlet

You plug it into the electrical outlet. I've not seen a USB connection on it.

The AC adaptor is not needed, it use the power from the USB3 which is adequate. However, it does have a mini DC plug that use 5 volts if you have to use the adaptor. I do not use this plug at all for this device or any other device that using the USB2 or USB3.

It is not USB powered, it comes with an AC adapter... however, a word of caution; when I purchased this it came with a "travel" AC adapter meant for outlets in Europe and will not work with US outlets. I had to research to find the correct AC adapter to get it to work and they ended up giving me a refund. It does work though, if you find to correct AC adapter which might be too much trouble for most people looking for a simple solution.

You plug it in. You turn it on. Most plugs from what I remember are AC. Strange question.

It only has a USB chords that connect to you laptop. You don't need a ac power coz your laptop feeds the power to the keyboard thru the USB chords.

It appears to work powered by the AC adapter or the USB 3.0 cable alone. My USB 3.0 external hard drive works without the AC adapter. However in order to charge attached devices like my mobile phone, the AC adapter has to be plugged in.

It can only be charged by USB.... AC Charger (with USB plug) is a lot quicker though.. It works great... charges my ipad about 2.5 times
