Hi everyone.I want to get a used car battery and wire it up to a 12v socket.Essentially, I have several gadgets that are supposed to plug into the cigarette lighter socket in a car, a tyre pump, a vacuum cleaner, a pump to pressurize water for car washing and a 240v converter (for laptop power)...... but I don't want the engine running while using these gadgets (gas is expensive).I want to charge the car battery at home and hook up these gadgets when I need them to this external power source.Would this idea work? Any advice for me? via /r/DIY https://ift.tt/2ygEaTv
