Duracell DC to AC Pocket Power Source Inverter 175 Watt #813-0291-07

Simplicity itself - - it justs works - for powering your laptop from your cigarette lighter or car battery.

I've used it several time, to provide power for my Lanovo laptop, never had a problem. It would be better if an airplane cable is provide.

Power adaptors for 65w notebooks can need more than 150w when the notebook need a lot of energy, e.g. with 100% of processor(s) use.

But this device can offer 135w of constant energy. 175w is just the peak power and really not true.

Do not use with batteries that offer low current levels. As a 12v to 110v transformer, it will need 9 times more current in the 12v input than the device need.

Besides that it is really portable and will power netbooks finely.

Works great to charge a laptop and run most small appliances. Don't expect to run your 52 inch LCD when the power is out on Sunday to watch a local NFL broadcast....I tried it didn't work. Fortunately the power came back on by half-time, but I was able to charge my laptop on it.

Light weight , small takes up very little room , does not generate a lot of heat ...very satisfied ...would recommend it Larry
