Frequently Asked Questions
What can a 1200 watt inverter run?
A 1200 watt inverter can handle most small household appliances. This includes coffee makers (check wattage), laptops, TVs, gaming consoles, and small power tools like drills. It can also run small microwaves (600-700W output) but may struggle with large hair dryers or toaster ovens.
Do I need a Pure Sine Wave inverter?
Yes, if you plan to run sensitive electronics. Devices with microprocessors (laptops, CPAP machines) or motors (fridges, fans) run cooler and more efficiently on Pure Sine Wave. Modified Sine Wave inverters are cheaper but best reserved for simple resistive loads like heaters or incandescent lights.
What size battery do I need for a 1200W inverter?
To run a 1200W inverter at full load, you are drawing roughly 100-110 Amps from a 12V battery. We recommend at least a 100Ah deep cycle battery (LiFePO4 or AGM) to ensure you have enough capacity to run loads for a reasonable time without damaging the battery voltage.
Conclusion
Choosing the best 1200 watt power inverter comes down to your specific load requirements. For absolute peace of mind and compatibility with all electronics, the Giandel 1200W Pure Sine Wave is our top recommendation for 2026. However, if you are on a strict budget and only need to power tools or lights, the Ampeak 1200W offers unbeatable value.
