I just swapped my car battery out and the old one is still in pretty good shape.
In a few weeks I am off on a long weekend away with my mates.
We have enough spare space to take the battery. We also between us have quite a high demand for charging various devices.
We all can't have a set of car keys, and we wouldn't want to run the car battery down anyway (mate's A6).
So how about I bodge up my own accessory socket with some crocodile clips and an accessory outlet? Would that be dangerous? What amps would I get? (- I'm thinking about the likes of Qualcom Quick charging). What could go wrong?
It'd have a lot more capacity than the battery packs I have (albeit less portable), which would be good for all the devices we have between us. Especially as my phone is gobbling battery right now for some reason.
