In all reality the input specs are the ones that are most accurate but in these cases there is little difference between the 2. The difference between the input power and output power is called efficiency.Efficiency of the device means it takes a little more input power to 'make' the output power. Some is wasted as heat but the difference is so minor in this low power stuff it really comes out the same., Most of these devices are around 95% efficient so just give a little extra when you use the output power. The inverter itself is 90- 95% efficient too.

I finally replaced the fuse for the cigarette lighter on my 335DS today (it is right behind the receptacle under the dash. Wow...7.5 amps. No wonder it always blows. That would be a total wattage of 90 watts, including losses from the inverter itself. Forget the 150 watt units...they will just blow your fuses!!!!

I hope you didn't put a bigger fuse in without checking the wiring between the lighter socket and fuse panel. Fuse size has to be calculated to protect the wiring as well as the device on the circuit. 18 gauge wire would normally be rated at 7.5 amps.

If the lighter itself is rated to 15 amps, you need 14 gauge wire to support 15 amps (and a 15 amp fuse) without overheating. Note that even a 15 amp circuit will only power a 175 watt maximum input inverter.

Actually to the contrary. I didn't have a 7.5 and with only 20,15,10 and 5 to choose from, I used the 5!
