Buy Sima STP-325 325-Watt Power Inverter Now

I got mine in 2004 while trucking. Used it for everything from camping to travel. I have overloaded it, blown fuses, melted the plastic around the lighter socket adapter tip, used it in the rain with only a plastic shopping bag protecting it.... Probably not so great for ventilation. Yes looking back on it now "young and stupid" comes to mind. This thing survived life on the road running my (year 2000) desktop PC with the big old monitor until I could afford to buy a laptop. It survived the worst I could throw at it and the built in protections have done their job. Get some heavy duty wires for it and it will serve you well.

This power inverter works great powering my laptop and charging my cell on road trips. It never overheats and the fan makes very little noise.

This inverter has ridden around in my family van for about two years now. We originally got it for a New York to Florida family road trip. Our van has an auxiliary video input for the rear-seat DVD screen, so with AC power available on the inverter, the kids could use their game console as well, and that was a big hit with them. The inverter had no trouble powering any combination of two devices in the two outlets: Game cube and laptop... game cube and cell phone charger... cell phone and laptop... I still use it occasionally for my laptop when in the passenger seat.

The inverter will trip off -requiring a reset by turning the power switch off and on -if it thinks there is an overload, and also every time the car is started, which is annoying but predictable. (Only a few rare times has the unit clicked off with a normal load that it is really capable of handling, but this never happened enough times to become an issue.) It also has an audible alarm if the input voltage from your car battery dips too low, to prevent draining it. This feature saved me once when I was waiting in a parking lot one night, working on my laptop, and I had forgotten my headlights were still on.

The only real con I could mention is that the cooling fan is quite loud, even noticeable over road noise. I usually stuff the unit under a seat, or under some other items in the car (while keeping the fan ports unblocked, important!) to minimize the annoyance.

The inverter comes with battery cables and a lighter plug, but I have never used the battery cables. Overall, I would recommend this unit to others.
