Rechargeable USB Emergency Power Backup Pack 2400mAh

Pros: This is a very useful item. I've been playing with it to power my random USB toys. It works great with the USB fan and USB 3 led light from here.

Cons: None, great device for a great price

Other: Great item for a great price, well worth it for a backup or for a fun all around toy.

Pros: I can charge my N95 when its low on battery.

Cons: LED is quite bright, see picture. no led when finished charging, confusing.

Other: get it at this price. not bad, and better than buying internal batteries for phones, knowing they might explode if not original

Pros: After some testing: - Real or very near 2400mah capacity - Small size and shape, good to carry in a pocket - Nice solid box

Cons: Not really, perhaps it should have some way of telling aprox remaining capacity (adjusting bright of led or something cheap like that)

Other: If you dont already have something like this, and you have some equipment that charges by usb (and I bet you do), then just get it. It really does the job.

Pros: This is a great little device offering a large capacity in a slender package. Can be charged either via USB socket or via pin socket. Good 5V regulated output.

Works well with my iPod and other USB gadgets.

Cons: None, although USB cables are a little loose in the sockets, making it feel a little cheap. However, in practise this does nothing to affect operation of the unit.

Other: For recharging USB devices and for powering my laser this item is perfect. I'd recommend it to anyone!

Pros: Works Great Inexpensive for its capacity

Cons: The accompanying USB cable does NOT fit inside the battery pack to charge it (the same one pictured). You MUST use the slide-out USB input connector to charge it but it may not fit in certain USB hubs or a computer's USB ports considering if there is insufficient space or objects such as a sliding door, etc., cover the USB port.

Other: Still worth it in the end.

Pros: Nice and small, easy to carry with me on a trip (which is why I bought it). Re-charged a Bluetooth headset for my phone and charged my Zune with it....worked great!

Cons: Instructions are lacking - apparently you have to have the switch in the on position to charge it. Would be nice to have a locking mechanism for the USB re-charge slider. Maybe having extra cables would help when slider doesn't fit in the USB port (which would be a problem for some).

Other: Great buy! Small and lightweight .... perfect for travelers!

Pros: - Great product - Hard plastic - Good capacity

Cons: - It overheating my products the usb charger of my nokia n95 gets very hot!!!!!!

- My usb battery from moixo gets very hot also! it even almost explode its that i discoverd it on time 8-)

- Think the output is to high the backup power thingy will always give a output of 450mA not what the device ask's at all :(

- Manual on back of package is not good english at all

Other: - Works when you need it and give's power when you just need it.

Pros: -Small and discreet -High capacity -Cheap price

Cons: -The USB cable I use heats up a little, but nothing too serious.
-Annoying text on the front.
-You have to switch it to 'on' in order to charge. Not a biggie though.
-Does not come with adapters

Other: You don't have to use this just for USB powered items. Just get an adapter from EBay or even from this site and you can use it for almost everything, as long a the input for it is 450mAh. I will be using it to power my external harddrive as well as my n810.

Pros: A USB universal backup battery, charges my DS and phone and my MP3 player Can be used on other USB devices, like USB fans and lights Handy led tells you when the battery is full Why carry around, or buy other batteries when you can just use this one

Cons: Plastic feels a bit cheap, but is still solid for me

Other: A great charger / power source via USB, good for laptops or the forgetful people like me who forget to charge our stuff before we leave.

Get one today! Now!

Pros: -cheap -easy to use -compact -lightweight

Cons: -does not work with everything
-usb power input is hard to get plugged into computer unless you use the cables provided

Other: Good for the money but won't work with everything, possibly because it's only 450mah output? I'd get something a little better though if I had to buy again.
