I can't tell you how much I love this product. I have an iPhone. The normal battery life is ok but not that great. I was at an all day event and needed to check my emails multiple times and be ready for a call from home as I had a sitter there. My phone started to die. A friend loaned me her iGo. I plugged it into my phone for just a little bit (I was worried about using all her spare energy), maybe 20 minutes. I had enough juice in my iPhone for another hour, maybe more, I don't know because after that I put it on my car charger. Anyway, that was my first intro to iGo.
I have a website. I received an iGo charger complimentary to test. Let me say, I NEVER also write Amazon reviews for things I receive in a similar nature. For the sake of disclaimer I have to throw this out there, but let me clarify I live in La Jolla and I can buy my own gadgets. :)
All that aside, I LOVE THIS. I probably would pay 3x the price for it because for my lifestyle, I need the extra charge. We travel a lot overseas. This does not need a voltage converter which for me is huge since we travel to London and Hong Kong a lot where the voltage is different (you'll still need a cheap plug converter, but not an actual voltage converter). It's small and I don't notice it in my purse or diaper bag. My daughter has an iTouch that she plays educational games on and all sorts of other electronic devices. iGo can boost almost all of them. For a long haul flight, this is a necessity for parents and children.
And how awful is it when the battery in your digital camera dies? I am constantly forgetting to monitor the battery life in my camera. I'm a busy mom, I forget. So now I don't have to worry about it since I have an iGo.
My husband is so sold on iGo (we have a Power Smart Tower too) that we're going to buy the Laptop Anywhere Charger and a bunch of the Power Smart Wall plugs as a part of our going green strategy. He's been asking forever to look into products that prevent vampire electrical usage (is that the right term?).
Sorry, don't mean to sound like an iGo commercial but we're just honest fans. Try it, you'll like it. Everyone I know that has one loves it.
