Battery power question?
I am using my laptop fwhile sitting in y truck via a power inverter, and connecting to the web via a city wifi connection, how long do you think the truck battery will last before I need to start the truck again.
The radio is off and no ancilliary stuff running other than the laptop. Thanks. |
A good power inverter should warn you before the battery gets too low.
|
thanks. i am googeling the question and I need to figure how many amp/h the laptop uses, not sure. May need to hook up a amp metere to find out.
|
Does the adaptor give any figures? Wattage for example?
|
Yes, the laptop adapter indicates 4.9A and 90W, what the calculation for amp hr I'm not sure. Thanks.

Lots of calculators on the web if you're rusty on your physics formulae.

Just keep posting every half hour, deportes. When you stop posting, we'll know the answer. ;)

Ha. Not quite true - he'll still have battery reserve power after that.
