So, having thrown some ideas into a couple of threads about
under seat batteries and
DC-DC charging, I need to actually plan what to do for leisure electrics this season.
When we were thinking about what our devices need when we go camping they are almost exclusively powered or charged by USB. Even when we've taken a booster battery pack camping we've only ever used the AC or DC outlets to run USB lights and an air pump. It didn't last a three night stay, which at 10Ah (usable) is not a surprise.
When we've booked an EHU extension we've used a fan heater, once, otherwise just packed the 4-way with USB chargers or previous to that, a baby monitor base station. We've even taken a 240V - 12V PSU with cigarette lighter socket to run our pump for air beds when we had a EHU and left the booster pack at home.
So could we make a 29.4Ah lithium all-in-one work. Well, it would last the three days of our normal use in tents without any problem.
But could we permanently run the lighting in a conversion from USB? And what about a fridge, one of the real tangible benefits of a camper? A compressor one would work, if we had solar permanently. Could we build a compressor fridge coolbox into a lined drawer by way of insulated jacket and thereby optimise the use of power within those limits. Well, yes, with a solar panel that could deliver 120W+ reliably, completely.
Back to the
@Dellmassive threads to find the panel and coolbox or fixed fridge? Are they more efficient?
