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.

Subject: CDN Tire Inverter questions

Beginning this Saturday CDN Tire is selling a 300W inverter for 1/2
price = CDN$24.99 (Lighter
plug or direct to battery).

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
