Default looking for car laptop charger?

140 Watt Power Inverter, Power Equipment | Walmart Canada - Save Money. Live Better.

Would this work to charge a laptop in the car? Laptop is a HP G4-1137ca. Any suggestions, I have no clue what brand or quality to look for?
Thanks.

As long as your laptop doesn't have an adapter over 140w. I've only seen intense Alienwares and Clevos, etc, that require that much power though.

Never LEAVE your laptop to charge with the car off, or you'll be stranded with a dead battery and half charged laptop.

I've actually got a 120W (I believe) power inverter for my wife's laptop, it works great other than the fact that it gets rather toasty when in use. Mine doesn't have the built in fan though, although we've had it in the car for 6 hours in operation (paired with a cheap usb gps) and haven't had any issues with it.

Goto Canadian Tire Get a 500-1000w inverter. Hook it directly to the battery with the correct fuse (100a). Then goto costco and buy a 500-1000w UPS back up and plug it into inverter. Then plug the laptop into the UPS. Might wanna put the inverter and ups in the boot though. :P

I would never use a 120w inverter that plugs into a 5amp power point (aka cigarette lighter) It's warm because you are probably pulling 4.5a on a 5a fuse.

It's like running a 12inch sub on telephone wire.

Personally, I would stay away from Car Inverters to charge your laptop. I've never had good luck with them. Odds are eventually you'll forget to unplug your charging laptop when you turn off your vehicle and you'll end up with a dead car battery. Just charge it up before the trip =]
