I plan on taking a camera, seriously who wouldn’t be taking a camera on a bike tour? I got myself a spare battery and a 12v charger off ebay for it.
It’s currently (no pun intended) charging up the spare battery off the Goal Zero solar charger.
Have also bought a similar item for the HP Mini laptop which can use the cigarette adaptor of the solar charger. Just waiting for that to arrive here. Both chargers cost about $12 AUD each.
