I am doing the Birdsville races in Aug/Sept with my son and his partner, kicking off the trip with a daytime crossing of Bass Strait, then the Mallee country, up the track to the races, then Lake Eyre, pandas at the Adelaide zoo etc, and all the bits in between. I will be taking my laptop and a portable HD to backup my pics, my problem is, as we will be old style camping all the way (no generator) and I'm guessing my son will always have some device on car battery charge, how in the heck do I keep the lappy battery charged?
I am thinking solar might be the go but don't want to pay mega bucks for what will probably be a one off thing... I found a 24,000Mah 10W solar charger that has a built in battery for under $200, does anyone have any experience with these? how well do they work?
