    I had problems with laptop switching power supplies tripping the inverter protection function. Basically, the power supply induces noise into the inverter output that makes it think that the output is shorted, and it shuts the inverter down. Resetting the inverter works for a time, but it eventually happens again. The modified sine wave also induces excessive heat in any switching or 'inverter' power supply that is connected to it. Newer microwave ovens use these inverter type power supplies. The microwave that I had would take 3X as long to cook something when it was running on a modified sine inverter, and it would usually overheat and shut down before the food was hot. Running on a generator or shore power, it worked fine. If I had my laptop and phone charger connected to the modified sine inverter, it would shut down within a few minutes. I could run one or the other for a few hours before it shut down, but both together would shut it down quickly. And they both got VERY hot within a few minutes.

    So, spend a few extra $$ to get the pure sine wave inverter. And you'll save yourself a lot of problems down the road.

    Like I said, never had that problem with laptops. Also ran a tv off one and never a problem.
