[OSM-talk] GPS logger

[OJ W]

The NaviGPS isn't ideal if you're away from a source of power, since
its internal battery lasts about 1 day, and you can't just put spare
batteries into it.

It might be possible to get somewhere with a USB power-pack to
recharge it overnight (that's what I used for a 1-week trek, which
meant constantly feeding batteries into the usb-recharging-gadget to
try and keep the NaviGPS' internal battery charged - not very
efficient)
