Laptop adapter?

Question

I am wanting to buy an adapter for my vehicle, the kind that will allow me to use my computer in my vehicle instead of using the battery. I have a 19" Sony Vaio laptop (very big and powerful) so I am wondering what to look for? Will I need a particular voltage, or wattage, or whatever? Obviously I am not up on this sort of thing, so all help is appreciated! I just don't want to ruin my computer, or overload the outlet port, or wharever... thank you!!

Answer 2

You might consider an inverter - converts 12vDC to 110vAC
Then plug your existing laptop ac adapter into the inverter.

The upside is that an inverter is probably cheaper than a mfr's DC-DC adapter, AND you can use it for other devices (never use low-end inverters for high-wattage devices like toasters, blenders, hair-dryers, etc...)

I use an inverter to power my portable office (Laptop + wireless router + VOIP router + all-in-one printer + 5.8ghz cordless phone) - people sure look at me funny when I'm sitting in a coffee shop (w/ internet access) talking on a home phone sipping coffee (little do they know that the phone charges are virtually free).

If you do opt for an inverter, get one with a 400-500 watt peak output (should cost less than $75US). The AC-DC adapter you have probably only draws 90-130watts (but check the bottom of the unit). Peak output is 2x the standard, suggested draw. So a 400watt unit can be safely run drawing 200watts for an extended duration.

Best of success.

Answer 3

look at the voltage and current rating on your AC adapter.

Match that.

You could always buy an adapter of Sony. They probably know which one you need.
