    The basis is as follows: 3w 4 = 12w plus the maximum loss does not use 15w, so the inverter can be selected to be greater than this straight (about 100W is too small to seem to be sold) The inverter current of the 15w lamp on the battery side is about, plus the total energy consumption of the inverter itself is about 2A, and the battery discharge rate is calculated by multiplying 2A by 4 hours 8AH, then the battery should be more than 12AH (the battery is larger to avoid the trouble of frequent charging).

    100w is enough for the inverter! The battery is 17-20AH 12 volts is enough, of course, you want to be safe, it is recommended that you buy a 35AH car battery.
