Can I use a standard car battery to power my inverter?
I bought a 400 watt power inverter that comes with 2 different leads. The first one has a 12v car lighter adapter and pushes up to 100 watts. It also comes with alligator clips that connect directly to the battery to push the full 400 watts, but I can t use it while the engine is running, so I was thinking of buying a separate battery, charging it with a battery charger and using that in the trunk of my car with the inverter hooked up for the sub I have.
Would there be any reason why this wouldn t work properly? I ve tested the inverter hooked up to my car battery with the key in the Accessory position. The sub gets nice and loud and it doesn t reach anywhere near 400 watts, so I have plenty of juice to power it.
What do you think? Can I safely use the inverter on a car battery until it dies, and recharge it overnight whenever I want to use it? Because if this won t work, I can still use the inverter on the 100w car plug. I just need some boom in the back; I don t necessarily need to be a full powered rolling bass machine lol.
Remember, I'm going to be using this inverter on a separate car battery which will be placed in the trunk. The inverter is going to be the only thing connected to the battery, while the battery that's already under the hood in my car will stay untouched. So will it be safe to use the inverter on that separate battery, and can I safely use it until the battery runs out of juice?
