Watts + volts X Amps. The laptop charger needs 114 to 155 VA or watts. So the 75 watt unit will not do the job. Go for the 300 and plan to install a proper cigarette lighter socket and 10 gauge wire for a 30 amp load. 300 watts / 12 volts = 25 amps.

There is also another 75W inverter for CDN$17.99 (lighter plug only). http://www.canadiantire.ca/registration/shopping_entrance.jsp Search for "inverter". I want to either run my lap top, or re-charge the lap-top battery and I can do this while the engine is running, so I will not worry about draining the Aux battery. My lap top AC to DC converter is rated: Input: 100-240V ~ 1.5A 50-60Hz 114-155VA Output: 19V --- 3.16A How big of an inverter do I need? I will only be running the lap-top. Can anyone tell me what I should be looking out for? I'm NOT very good with electricity, so KISS. Thanks. M __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
