It does not have to be plugged into a computer or other source of energy to work, right?

Hi Kristin, the bottom area of the battery has a iPhone 30pin plug in for you to charge using your iPhone 30pin USB cable. Anyway, my advise is to look for other options as this aux battery only lasted me like 2 weeks. The quality really sucked! Don't waste your hard earned money on this one. Hope my advise helps....

It seems like it has to be plugged in. I didn't realize it was intended to work without being plugged in

Yes, it is powered.. However, you can obtain a great workout without plugging it in if needed.

No, it needs to be plugged in. However, you can put it on a built in timer so that it is not always using electricity. This is a purchase that holds NO regrets for me. Use it everyday and bought one for our daughters with small children who say that it is invaluable for heating food quickly, warming baby bottles, etc.

yes -- and it works perfectly either way. I have it plugged in at home, but can take it with me also when there will be no electrical outlet

Yes . . . otherwise it will be sourcing power from your PC, and it is designed to you it's own power source.

Ron....no, the hard drive is a plug-n-play, no external power source needed.

No power cord required as it runs off of your USB port directly into your computer.

This device has a battery so you don't have to keep the power plugged in. Still though I wouldn't recommend this product.

It is powered by usb through your computer. No other power supply is needed.

Sure you can. But you will not need to keep it plugged in. It should do the job without a recharge.

You could look at it that way - or like a laptop - it doesn't have to be plugged in and it can go where you are - if there is a plug or not.

No. This device does not need external power. Direct plug and play ( like a thumb drive)

unless you have one of those USB Back up battery for when you don't have electricity. You'd still need to plug it into a power source. Doesn't have a stand alone battery.

It has built in rechargeable battery so does not have to be plugged in all the time.

No, you don't need it. It works with the power suministrated by the usb cable taken from the PC, Laptop, iPad or iPhone.

No. It gets its power supply from the raspberry itself. No need for external power
