Amazon has this Lenmar 5V 3.8 Wh AnyWhere charger for only $6 (with free shipping if you’re an Amazon Prime member – as you should be). This charger is strictly for emergency use. Re-charge it via your USB port (expect this to be an overnight process) and it will give you an added re-charge when you most need it. The tips included claim to power iPhone/Touch and BlackBerry. I haven’t tested this particular brand so YMMV on how it works in the field. The Amazon comments are a little mixed with most saying it takes a long time to re-charge the battery and a short time to discharge when connected to your phone.
I can however recommend a better solution that will cost a few bucks more from Amstron which I’m currently testing and love (larger variety of charger tips included, a wall charger, plus I can verify the Amstron charges the iPhone 3G and iPod Touch as well as BlackBerry). For $6 – this Lenmar may be a worthwhile deal. Buy it and charge it overnight before a trip away from a power source. Looks like Lenmar also offers a $35 version with a few more accessories and larger capacity.
