Miccus ChargeBlock Mini, External Battery Pack & Charger For iPhone & iPod CBFI-01

Pros: Small, Light & can save you when your iphone battery is low. This was a great buy as a $20 Shell Shocker. When plugged in there is a space between the battery and the phone so you can use the speakers/mic normally and can also use it with many cases. Since it is small it is less clumsy than some other external batteries when plugged in.

Cons: Smaller than the internal iPhone battery so it will not completely charge your iphone if it is too low. Since it attaches to the dock connector you want to be careful how you handle the combination while it charges. I find it clumsy enough to not use it regularly to offload some of the wear from my internal battery. I just user it to charge while I'm on the go.

Pros: Small and easy to charge with battery indicator. The best back up iphone charger I've had so far. Easy to plug to the iphone.

Cons: It doesn't give you much of a fully charged back-up battery that you need. The battery on my Iphone was 13% and when I plugged this thing in it was only able to charge up to 76% and died. I wish it could have longer battery life. The reason why I bought it was because I was hoping it could at least fully recharged my iphone when the phone dies but it doesn't. I like it but I'm also a little disappointed.

Pros: Small, stylish battery back-up a must have for any I-phone users.

Cons: Wish it charged the battery a little more.

Overall Review: I keep mine at work always ready to go, it has saved me countless times.

Pros: Light weight, fast charging, easy to use, and amazingly cheap.

Cons: Needs to be charged separately.

Overall Review: This is an amazing product! Having a secondary battery for my iPhone really takes the headache out of traveling. I always carry one in my bag just in case I forget to charge my phone.

Pros: I end up needing this several times a week. I especially like the charge indicator lights and the fact that it attaches to the phone even with my case on (no cables). I have another charger that connects via cable that I don't end up using anymore.

Cons: None.

Overall Review: Hard for me to get in the habit of keeping something else charged but it's awesome to have a second battery for my iPhone.

Pros: This little guy has saved my keister numerous times. I use it at least 4-5 times a week. I keep it in my bag and when I get the iPhone battery low signal just plug it in. Works fine right through my case and allows me to keep yacking.

Cons: My brother keeps borrowing it for use with his iPod touch

Overall Review: Between work and school, I dont always have time to charge the iPhone the little ChargeBlock keeps me surfing (um I mean listening) during lecture.

Pros: Great for iPod and iPhone users on the go. Charges devices quickly, fits iPhone nicely and travels well. The iPhone can be used while the charger is attached. And, there are no cords to worry about damaging or losing.

Cons: None

Pros: Plugs into the phone and is small enough you can talk on the iphone while it is charging. Will charge your iphone from 20% to over 90% in about an hour.

Cons: None.
