Has anybody used one of those car-jump starter/battery back-ups to run an oxalic acid vaporizer? It would be nice to have a dual use product (vaporizor power source, emergency jump-starter for the car, and back-up power for phones when I am off on trips).
The ones I am finding are typically 12V, 20000mAh. I am a back-yard beekeeper with only a couple of hives located on my home property; I have no problem recharging between uses.
I am not the best at electrical stuff, perhaps someone else could help?
