I just bought a battery pack from DinoDirect for my iPhone 4 which i find it pretty cool for the reasonable price. It does do it job by double my iPhone 4 battery life. The downside is that it doesn't really have it for iphone 4 although it fit into the battery pack. Which mean there is no front camera support. For iPhone 3G, it fit very nicely and tightly.
Overall is a great products with a reasonable price.

Capacity: 2100mAh
Input: 5V 500mA
Output: 5V 500mA

Charging Time: About 5.5h

Size: 133 x 66 x 18mm / 5.2 x 2.6 x 0.7in (L x W x H)
Features:
This is a non-OEM product
Rechargeable battery pack that doubles as a complete protective case
High capacity rechargeable external battery

Smoothly match the style and design of the iPhone 3G 3GS
Pros:
- On / Off buttons.
- Acceptable capacity with double the battery life.
- Can be used as a normal iPhone while charging with few consequences.
- Good price for what you get.
- Here you can connect any USB power, and the battery pack will make the iPhone accept the power.
Cons:
- As I bought it for iPhone 4, it doesn't really fit onto it as it leave a gap on the side.
- It makes the phone a lot bigger.
- Does not has a batter power indicator to show the battery life.
- Part of the camera on the back is been cover. Could be due to iPhone 4.
