there are two main differences between a pure and modified sine-wave inverter: efficiency and cost. Pure sine wave inverters are good at two things: efficiently powering devices that use AC, and powering devices like radios that can suffer from interference. But, they can be expensive. On the other hand, a modified sine wave inverter may produce some interference, resulting in a less-than-pure current, but they are less expensive than their pure-sine counterparts.

If you are in need of an inverter that is going to power sensitive electronics such as: medical devices, computers, anything with a dimmer/variable speed, heater/heating coil, or just needs clean power; buy the pure sine inverter…
On the other hand, if you need temporary power while tail-gating, camping, road-trips or to charge your laptop/two-way radios, power fans, run a blender, power a microwave, etc., the modified sine wave inverter is smart and affordable choice

For Inductive Load : If connecting with inductive loads (e.g. Compressor, Pump, old CRT TV, Refrigerator, Ice conditioner, Air conditioner, Relays,Fluorescent lamp, Vacuum cleaner), please choose inverter whose rate power is 3-7 times higher than the load’s rate power. For example, for a 150w refrigerator, please choose a 1000w inverter or higher; for a 800w air conditioner, please choose 2500w inverter or higher.
For Resistive Load : If connecting with resistive loads (e.g. Computer, LED TV, Fan, Scanner, Fax machine, Duplicator, Sound system, Juice extractor, Heater, Electric cooker, Coffee maker, microwave, crock pot), please choose inverter whose continuous power is a little higher than the load’s rate power. For example, for loads near 700w, it’s better to choose inverter with continuous power more than 800w.
