Q9: What are resistive load appliances?                            
A9: Resistive load appliances include devices like smartphones, computers, LCD TVs, incandescent lamps, fans, video broadcasting equipment, small printers, electric mahjong tables, and rice cookers. Our power inverters can effectively operate these devices.

Q10: What are inductive load appliances?
A10: Inductive load appliances are high-power devices that operate based on electromagnetic induction. Examples include motors, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These appliances typically need much more power at startup, about 3-7 times their rated power. Only pure sine wave inverters can reliably power these devices.
