Compact size.  The eight inch cord is just long enough for most of my needs of changing on the go.

It is very compact, and it works very well.  I could get rid of the extra cable that was not really needed for my use.

It's perfect size and powered by USB port (don't need to plug into outlet like hard drives that get to be this size).  It's worked great and the size is just perfect. Cord is short that plugs into computer, so get an extension or longer cord if you want distance between the item you are plugging it into.

ok, a small rubber little doo dad.  But serves its purpose.  Others are correct that it does not have snough room for a whole earbuds cord

Compact size. Works but slowly. Cord that it came with it too short to reach any wall plug. And the phone has to be positioned in the exact center to start taking a charge.

Love these mini cables! I was looking for something short to attach a portable charger to my phone in my purse. Longer cords take up way too much space and these are the perfect size.

The cord could be longer but it does fit securely into the power socket.  The blue light on the plug is nice.

This is a small compact unit which is very light and has a rubbery casing. It's dimensions are 11/2" by 3 1/2" - easily fits in the palm of your hand. It has a port for charging, earplugs and on/off switch on the bottom edge and a simple dial for controls. Navigate the unit by using the outer dial for scrolling through various options within a program and the inner button is to 'set' or 'confirm' your choice. Quite straightforward, especially for those already familiar with mp3 players. So far working fine for me.

Small and compact. I keep it in my camera bag . Can take awhile to get a full charge. Wouldn't leave home without it.

Great price, compact size, decent charging speed. Took a Note 8 from 50% to full in 30 minutes. I haven't tested it to see how how many charges I'd get out of it before recharging the charger. But it does what I need, tops off my phone until I'm home when I'm out using it all day. It is about the size of a large lipstick tube. The color is as pictured.

This is very small, at 3.4 x 2.7 x 0.7", and has a wrap-around USB cord that makes it convenient to use.  Too bad the internal 1.8" hard drive isn't accessible/upgradable, but that might make it bigger.

It looks like there will be some competition for this thing in the near future from Plextor, with devices that are thinner (0.5" or 12mm) but otherwise a similar size, though without the wraparound keyboard.

Flexible cord, easy to install. Good size.

Its small but that makes it more portable, its more for close like about 4 feet.

This shorter length extension cord is just what I needed for a specific space.  The angled plug is also helpful.

It was more compact than I expected and the cord accessories made it a good buy!

Power cord is long enough to reach those hard to access outlets.
