Inverters are a case of "you get what you pay for." If you only need it to power a laptop, a low-power inverter is sufficient. However, if you plan to use it for other purposes in the future, you'll need to consider a more powerful one. Ideally, you want a pure sine wave inverter, and at the very least, a modified sine wave inverter. Square wave inverters are not suitable. Also, inverters use high-frequency switching tubes, which could interfere with shortwave radio stations, just like car battery chargers.
