2200mAh Rechargeable External Battery for iPhone 4/3GS (Red)

Pros: 4 Blue Led Lighting to check power level. It is not heavy. The matte finish feels good to touch. Design is very nice. Can hold 220% +/- Charges for my Ipod Touch 3rd Gen Means it can charge up from 0% to 100% for 2 times. It is quite cheap for the amount of charges it can hold, i saw a few portable battery online and most reviews said it can only be charged 1 time.

Cons: Not much cons really except that no dust cover and no port cover.

Other: Buy it. You will not regret it!

Pros: Bought 3 units for myself & friends for our iPhone 4 * Charges my iPhone 4 from 20% to 100%, while it's on but not in use * Pretty nice design & feel, sleek red rubber skin * Can be chained with the iPhone and wall-charger to charge both at the same time * 4-LED indicators work well

Cons: * Only works with a "bare" phone, will not attach if there is any back-cover, case, pouch etc. * Also, won't fit when you want to put the iPhone in a car cradle * 3-4mm thicker & wider than the iPhone 4, so kind of a bulky couple during the 2-4 hours it takes to fully charge

Other: Good and handy, fantastic value for money. I've stopped running around with wall & car charges, feeling like I have to "beast-feed" my iPhone 4 every few hours like it was a baby

Pros: The colour is catchy, bright red.. kinda nice. It can charge a hell lot more than the other lower range mAh charger. The rubber feel of the item is great. Price is reasonable.

Cons: There is no cover for the top charger part. The charger appear to be only able to charge on a specific position, if you were to move the charger slightly a bit, it will disconnect from changer.

Other: If you want a reasonable and nice portable charger, this is one nice piece of item to have.

Pros: - Red colour is is very bright. - Velvet look. - The surface has a rubbery texture which is good to feel. - Design is good. - Blue LED indicator is very nice.

Cons: It was only able to charge my Iphone 3GS up to an extra 40%. (Note I have already charge and discharged it for more than 3 cycles as per new rechargeable battery practice.) The Iphone must be naked in order for it to connect properly to charge. In other words, you have to remove any cover that you have on the phone to connect properly.

Other: Not a very good purchase for me. Maybe I got the lemon stock.

Pros: The good thing about this is it's about half the size of the Ipod. It fits nicely in my hand. It's not too heavy, it won't strain your wrist to have it attached. There is a button that can be clicked to show power level. It came charged and got my Ipod up to 90%. I imagine if I charged it up fully it would go all the way. I think the price is alright. It clicks right into the bottom of the Ipod. I'm not sure about other devices but I like the feel of it clicking in. It means it's going to stay in and not fall out.

Cons: Ok so the power button that you click doesn't really click. It's hard to know when you have pressed it fully. Other than that I can't think of anything.

Other: Good product. Well worth the price. Fits snugly into my device. Great for everyday carry.
