I have read what others have posted about this charger and I can agree with their gripes:
-short usb cable
-questionable quality of plastic (borderline "cheap" feeling), especially for paying almost $40
-connector swivels and can be annoying or required getting used to

But let's talk about what this is... a portable charger for the iPhone.. and for this I think it's excellent. Why?
1. has indicators for how much power remains
2. provided me with at least 2 charges (not 100% charges but at least 50-60%)
3. can act as a stand/dock OR hand held battery (while talking on the phone)
4. holds charge for several days without use or topping off

Could the connector be more definitive? Yes, it could have been designed to click into various angles instead of swinging freely.

Could it be a better fit and finish? Yes, it could feel a bit more substantial without getting heavier. I have owned similar products that felt like better quality.

Could the usb cable be longer and/or fit into itself better? Probably yes, but it's not a deal breaker for me.

I found it to be a little on the expensive side but since it functions well I am still happy.

Knowing how much power is left in your "backup" battery is key! Otherwise you carry a backup which might be dead, really wasting your time!

Having a battery that doubles as a stand/dock is really nice. Additionally its not awkward to have the battery connected and talk on the phone. Multi use is a bonus.

I have owned smaller batteries which indicated how much charge was left when it is plugged into the phone or is charging, but not where you can press a button and find out quickly like this one. Plus, the other batteries which were smaller didn't hold much charge, barely enough for 3/4 of a charge.

I hope this review helps you.

This could be a great product but it has all the making of a product designed over a lunch. The connect swivels so it's difficult to fit into the iPod as it keeps moving. The support leans back but the connector won't allow the iPod to lean back so it sits bolt upright. The on-board USB cable is so short it's useless so now I have to carry a USB extension. The documentation....What documentation? If you want to use it as a charge stand it would be nice if they gave you some specs re the power supply (the one they should have included for this price) as it must be capable of charging both the on-board battery and the iPod/iPhone simultaneously - the first power supply I tried didn't work. It's also cheap plastic that probably won't survive a drop.
I estimate this should sell for about $10. It's not worth any more than that.

This is a neat little stand for the iPhone that folds up very compactly and includes a battery backup. It's made of cheap plastic and the USB cable is absurdly short. If you are looking for a travel stand for your phone, to use it as an alarm clock or other similar use, this might be worth considering, for the battery backup there are certainly better options that are more user-friendly and provide a lot more power. The $30+ price currently for this seems excessive for the quality, but it might be worth considering for half that.

I was videotaping the event the other day and before the last performance I run out of the power. Then, I remembered I had Kensington Backup Battery!

It worked very well and I successfully recorded the last performance. I could use the stand on the table and the video turned out to be better than the one I was using my hands.

It's also great to be able to read Kindle for iPhone hands-free. I love this battery.

I use this with a 2G iTouch and a 5G Video iPod so its main purpose is to be a convenient portable battery backup if an electrical outlet isn't available. It fully charges in about 45 minutes. The self-contained cable is only 3 inches so it will sit very close to the computer unless you are using a hub or extension. I charged it and then it sat in my bag for about a month before I needed to use it and found it still fully charged. Checking the charge is simple, press a button and blue LEDs light 1 up to 4 for a full charge.

If you use FaceTime you would like the convenience of the stand feature of this dock. Unfortunately it does block the headphone jack on the iTouch so you can't listen to music and charge the battery at the same time.
It is small and lightweight but I do wish it came with a pouch. The connector folds against the unit but still exposed and vulnerable to debris and damage.

Wow. Bought a PowerLift last June. Tried it out big-time today. I was caring for a deathly-ill elder cat last night--she went into a coma. I stayed with her and wanted to play non-stop low-volume soothing music (barely audible to humans) on my iPod for her. The iPod's battery pooped out after merely two hours. It was not the time to look for a cord and outlet to plug the iPod into. I attached this diminutive PowerLift battery, and my iPod has been playing music for 11 hours straight. And it's still going. I'm impressed. The music helped; my cat pulled through.

When I went flying on an airplane, the iPod pooped out on me early in the flight. I was not amused. I had to go music-less for the rest of the trip. Now I'll take this elegant battery with me.

The PowerLift is well-designed, functioning as a stand. For during phone calls, it folds in front, out of the way. This little device is priced well too. It's a great BACKUP battery. I'm going to buy a second one for my hubbie. I like when companies put out well thought-out products. So much stuff is created with no other vision than to make a fast buck. I recommend the PowerLift highly.
