In Reply to: OT: power invertor for laptop posted by TommyZ on June 07, 04 at 14:55:02:
I purchased a Wagan pure sine wave inverter from safehomeproducts.com.
We use it for laptops, TV, charging various video devices, etc. while on the road.
The pure sine units are a little more $$$, this one was about $100. It's a 150 watt/300 peak watt unit with overload, overheat and low battery shutoff. Any bigger unit would require hardwiring to the battery or an aux terminal. 2 outlets.
The modified sine units are cheaper (around $30) but the dirty waveform can cause interference with some devices and may actually damage some sensitive electronics. Think of a pure sine unit as a combo inverter/line conditioner as the waveform it generates is usually cleaner than the one coming from your wall socket.

: I know this has been discussed before. Have a Dell Inspiron 5100. Would like to power it through an invertor from the second row 12v plug. Dell does not sell an invertor for this specific unit though they do for other laptops that require less juice. The 5100 AC adaptor outputs 90W. Want to use laptop as DVD player for kid while traveling this summer. Those here with technical expertise: does the fact that Dell does not sell an invertor for this unit mean it is not a safe practice for a 5100 even if I find a third party (Radio Shack)invertor that meets the 90W benchmark? Just stay with extra battery? TIA for all comments. Tom in Phx.
