Power Inverter for laptop


Trying to get a power inverter for a friend's laptop. The "official" car charger from dell is here, and 65 Watts:

http://accessories.us.dell.com/sna/p...9&sku=330-0732

Does this mean I have to get a 65 watt inverter, or can I get her a 90 watt inverter, so she can use it for things that my require a bit more power?

Maybe something like this with USB:

Any suggestions?

Thanks.

You can get as big as you want but it needs to be atleast 65 watt.

What, exactly, are you looking for?
The first link is for an AC adapter. This plugs into a wall outlet and provide DC power to the laptop.
The second link is an DC inverter. It converts 12DC to 120 VAC. You would then need an AC Adapter to provide power to the laptop.

Yeah, the inverter is fine. She already has the AC adapter that came with her laptop.

I am thinking the inverter is better, since it'll give her a place to plug other things in as well. Some even have a USB port on them to charge iPods, etc.

I linked the wrong adapter in the first link, I meant to link the car charger.

Do you think getting some no-name brand inverter w/ USB for $12 is a bad idea, or are they one and the same?

You can get an inverter with 90 watts available for $12?
It probably doesn't matter that it is no-name, they're all made in china.

75W won't power much, so if you want something you can use for other uses, I'd get a 500w or so. They are fairly cheap, and very handy to have.

Beware though when get into the higher wattage converters you will most like be wiring them to your vehicles battery as opposed to plugging them into your cigarette lighter outlet. Those outlets can usually only handle 10-15amps of draw.

As long as it works for her laptop and iPod at the same time....that's all I want. I'll probably just go with 100w or so.

I have a 100 watt inverter that plugs into the lighter and I use it to charge my batteries.
Black and Decker, and cost about $20 at HD.
No usb port.

I have had very good experiences with inverters from Tripplite - I have used many to include both their smaller portable units that plug in, to the larger permanent hard-wired units. Quality products, good value, and a solid very experienced company.

The model 150 would work for you - http://www.tripplite.com/en/products...xtModelID=2553
