Pros: good product. You have a nice and portable battery wich you can charge with a usb plug and wich has also as output an usb plug
Cons: I am wondering if the capacity is right. Also I have the idea that the battery drains out if you let the switch in the "on" possition
Other Thoughts: an friend of mine also bought this product but het got one with a red led...... the mine has a green led.....we didn't find out if that is the only difference or that one of us really has a newer version
Bottomline: just buy it! It is maybe not as great as it looks but it is very usefull at vacation!

Pros: - Very cheap, it does indeed charge my various devices, it has saved me several times.
-The small size is nice.
Cons: - Doesn't fully charge my Nokia N800, but you can't expect that much at this cheap price.
- The green LED is very bright, I don't see the point to it.
- The battery has broken twice, it isn't held together very well, so be careful with it.
Other Thoughts: If you need to fully charge something big (like my internet tablet that has a 1500 mAh battery) you might want to look at a more expensive battery.
If you need to charge iPod touch/iPhone and know some electronics, google 'DIY iPhone charger' this is at your own risk of course.
Bottomline: This will give you a fair amount of extra power to your stuff, but might not fully charge some more power hungry devices.
great product

Pros: I am using this to power a hand held GPS instead of the two AA disposable batteries held within the unit. The GPS unit will not work properly with rechargeable batteries so it was becoming very expensive to use. This Pack powers the GPS for many hours of use so it will pay back my small investment quickly.
Cons: The pack has no Cons at all. The Instructions included are quite confusing.
Other Thoughts: When the Pack is powering something the green LED will be on. The LED will go off with switch on if nothing is plugged into it and drawing power from it. When recharging the switch must be on and the LED will be on while charging is in progress. When the Pack is fully charged it will automatically shutdown recharging protecting it's self from overcharging and the LED will go out so you know when charging is finished.
Bottomline: This battery pack is just the thing for any device that can be powered via a USB cable. This is well worth the price. Order several as everyone in your family will want one of there own!

Pros: Very useful, construction good
Cons: Mine shows the capacity on the label as only 1000 mAh, not 2400mAh as quoted and shown in the illustrations. Maybe the led should indicate whenever the unit is switched on, even if not connected to anything. Also maybe some form of state of charge indication.
Other Thoughts: Maybe supply with a range of USB adaptors for powering and/or charging mp3 players, cellphones etc
Bottomline: Would need to do tests to confirm actual capacity, but if it is only 1000mAh then its use for me is not so good, I'm hoping the label is just a misprint.
