Verified Purchase
I bought one for my phone at a retail store. Pricing wasn't much different. This is a must for IPHONE travelers. I told my husband he would be jealous. He was. I never had a dead battery with the extra back up options. I couldn't find him one at any store locally. I found it here &ordered it. He loves it! Thanks again for another happy purchase.

It does help me when my G3 iPhone is low on battery power. It take about 45 mins. to add %25 more life. Was hoping for more like %50 to %75. The PowerBlock LED lights drop quickly from 5 to 1 in about 5-10 mins. It takes about 2 hours to charge back up from car or wall adaptor. The PowerBlock design is great and even fits with my bulky 'Contour Clip" protector so I don't have to unpack anything. I like the magnetic way the PowerBlock clicks back into its charger. SO if all this sounds OK I say buy it. [ I've had it for 3 weeks ]

I purchased this product because I use my iPhone 4 constantly for my business and personal use and my battery is usually dead after about 6 hours. I was excited to use the product until I found out that it only boosts your battery power by about 20 percent and that's only if you don't continue using the phone while you have the extra battery in. For an extra fifty bucks, I could have just bought the Mophie Battery charge case and had much better luck. If you use your phone a lot, this product doesn't help much....

The Griffin PowerDuo worked very well for the first five months. Then one day it stopped working entirely. I only had this product for 5 months and used it maybe ten times max. Thus, only one star.
