Portable 4200mAh Rechargeable Power External Battery for iPhone 5 - Black

Pros: really useful gadget. as I use my iphone 5 for work the battery is used a lot. this is the most practical solution i found, and I use it almost every day.

Cons: not to confortable to use, but its still a great gadget. also the time of charge is a bit slow. when I oppened it the charger pin was a bit moved so the phone didnt plug in. I had to move it a bit, and then the phone plug excelent and works great.

Pros: The battery case looks nice. You plug it into the iPhone's regular cable and just slide the phone into it (this is nice because there are other batteries with clumsier setups). It gives the phone 3-4 extra days of juice, which is very useful when using the GPS for long voyages or when watching movies on a plane. The case is designed for easy access to the phone's normal jacks and buttons.

Cons: The kickstand is very flimsy - I didn't try to use it because it looks like it could break any second. The battery level readout is not so reliable - it dropped for me from 50% to 0% in less than 2 hours.

Other: Very handy item - useful to have.

Pros: I'm impressed! In my first test, I used this extended battery to power my iPhone 5 from 0% to 100% battery (phone was used minimally during the charging). When the phone reached 100% capacity, this extended battery showed 75% power remaining. Impressive! Summary: - Will charge the iPhone 5 at least 1.5x (from 0% to 100%). -Excellent fit/finish and amazing capacity. - Great value! - USB charging port on the side (can be used to charge other USB devices - aka universal charger as a bonus). - Accepts standard Apple Lightning cable to charge.

Cons: - Adds some bulk/weight to the phone (but that is expected b/c of the 4200mAh battery). - Recessed audio connector may be troublesome.

Other: If you are tired of running out of power on your iPhone 5, you need this!
