you know if you're out and need a little juice for your battery, do they make portable chargers that you can carry with you? ones that ere battery operated or you power up before use, etc.
thanks
The Brookstone model is $20 and comes with a battery. So you can buy immediate backup power at an airport in a pinch. One single use might justify the cost. But I agree with you. It feels like wasted money until you need it, so I've looked at them, but never bought.

I do a lot of outdoors stuff, and use one of these, which has adaptors for most kit. Has a solar panel as a backup as well. Very useful when camping etc.
I use one when battery is down.
The initial cost sounds good.......plus batteries (and the el-cheepos dont work for very long) increases the price 10-fold.... really it is handy but carrying a spare charged battery is more economical.
