FAQ:

Q: Who makes the best inverters?

A: Brand: Renogy Model: RNG-INVT-1000-12V-P2 Wattage rating: 1,000 watts

Q: What is the best power inverter?

A: WindyNation VertaMax Modified 3,000-watt 12-volt Power Inverter AIMS Power 3,000-watt 12 vDC RV Power Inverter Ampeak 2000-watt 12-volt RV Power Inverter Xantrex 81201012 Inverter

Q: What size of inverter do I Need?

A: Size: 7.48*3.93*3.23in Weight: 1.76lb Best for emergency use,charging USB devices in a car

Q: How many amps does a 2500 watt inverter use?

A: • It is the actual load watts, not the inverter rating that counts. So a 1500W inverter with a 500 Watt load would be 50 (25) Amps, not 150 (75) Amps.The same inverter with a 1200 Watt load would draw 120 (60) Amps.
