If you appreciate the form factor and style of the Hero Cordless heater but need something a little more powerful, we have just the thing for you.

It has a variable heat control dial on the side that allows you to adjust this unit from 30,000 to 60,000 BTU in seconds. That’s good for areas around 1,350 square feet, which is extremely impressive once you consider the size of this heater.

8. Hero Cordless Heater

As mentioned, cordless systems are rare in the heating world, and the Hero rechargeable heater is one of the only systems to pull off wireless heating with ease.

Quality control appears to be a little spotty on these units, however, and we’re not big fans of the plastic fan. Optional second battery for extended runtime, trickle-charger, and compact design.

• Pros: Truly cordless, compact, optional second battery
• Cons: Quality control issues, plastic fan durability

However, a slight propane smell was noted, requiring ventilation.
The MaxHeat Pro 2025 was tested in a 200 sq. ft. indoor office during a power outage. With its dual 10000mAh batteries, it maintained a comfortable 70¡ãF for 10 hours on the low setting, with silent operation ensuring no disruption during work. The PowerHeat Pro 2025, tested in a 100 sq. ft. garage, warmed the space by 10¡ãF in 20 minutes but required a battery swap after 4 hours on high.
The Ridgid 18-Volt Hybrid Heater excelled in a 1,000 sq. ft. workshop, heating it by 20¡ãF in 45 minutes on its 60,000 BTU setting. Its propane dependency limited cordless operation, but the 18V battery-powered fan ran for 7 hours, making it ideal for large spaces.
