My PI-266 lap top has a deal battery.  I have a 300W inverter and it works
just fine for it.  Have powered a small B+W TV with it too.

If the inverter can give out 300W then you just need to know this
formula.... P = I x V  Where P is power in Watts, I is current in Amps, V is
Volts.

Assuming that the 1.5A is for 115VAC input, it would be P = 1.5 x 115 or P =
172W, as a rule of thumb always leave 10% for the gods, so 190W inverter
would be the minimum needed.

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
