It might just be me, but I have so many gadgets, purchased over time, that as I move on to other devices and scenarios in my life, I sometimes forget I have some really useful tools still available.

Case in point. With the improvement in battery life of the current crop of phones, not getting thru a day on one charge has been minimized. My HTC Tilt 2 so rarely threatens needing to be plugged in before bed time, I have stopped thinking about when it might. I keep a great external battery in my car for emergencies, the really sweet Tekkeon Power-All, but it is just big enough that I don’t relish carrying it unnecessarily. Yesterday, after a rare day of much Wi-fi, Bluetooth and extended call usage, and my car was elsewhere, I was on an important call and got the dreaded “low battery” warning. I really needed to be able to finish this call. It dawned on me, like one of those “well duh!”, I also have the Proporta USB Turbo Charger 3400 in my bag. I plugged it in an had enough juice to save my bacon and get me home. This little gem is so convenient to carry, I forgot why I do AND how valuable it is.

So if you are looking for convenience and inter-device support in the charging arena, I’d recommend checking out the Proporta 3400. Here’s some specs and features:

This ridiculously handy product allows you to recharge your mobile devices on the move again and again. Simply plug any USB/micro USB powered gadget (including your Apple iPhone 3G/3G S, Apple iPod, BlackBerry, most digital cameras, GPS units and mobile phones) into the USB TurboCharger’s standard USB port and it’ll keep even the most power hungry device juiced up and ready to go. An LED display shows the level of charge, and this lightweight and stylish battery is so small that you’ll hardly even notice you’ve got it with you.
