Travel Technology - DC inverter for in-air use (AA cigar lighter type)

Does anyone have any recommendations on DC inverters for use with laptop that will work with the plugs on AA?

Thanks

depends. some laptops require too much power to use inverters on the plane. if yours has a low power requirement, look at the specs on your laptop power supply and head to radio shack to find one that exceeds those specs by a bit...

AA power take offs are rated 75 watts. You need a cigarette lighter (auto) tip plugin. Many newer laptops (eg ThinkPads)are 90. Even with invertor you may have to power down to get it to work. If you trip the circuit- wait 20 seconds and replug.

Skymall has it for 49 i think but you can get it cheaper elsewhere ( i got min at fry's for 27.99). I have tried several but this is the smallest i know of with a fan and a usb port. excellent value.

Given the previous discussion in this thread, could you tell us why you recommend a 120watt power supply?

I have an HP with a large 17 inch so it sucks up a lot of energy. I use an IGO 130 that works well on all AA planes despite the 75 watt limitation discussed here earlier.

Keep in mind that adding an inverter to your existing power supply (a) is a lot bulkier than, (b) is a lot heaiver than, and (c) may use more power than (and thus if your laptop is at the margin of working with AA power, be more likely to cause problems than) a replacement "universal" power supply that works on either AC or airplane power (the latter either AA-type cigarette lighter, or the EmPower type that some other ailrines, including some of AA's partners, use), such as the ones from IGo (available at Amazon among other places; a lot cheaper some places than others). And some of them can even double as your cell phone charger, minimzing weight and clutter even more.

Absolutely positively right. You're taking 12v DC, stepping it up to 120v and then rectifying it and stepping it back down to whatever voltage the laptop takes. There's quite a lot of inefficiency involved. Much better to have a power supply that does it all.
