Our Verdict
The Portable Buddy runs on propane fuel, not electricity. It delivers 9,000 BTU with no outlet required. This makes it ideal for garages, job sites, and outdoor spaces.
Two safety features are built in. Tip-over protection and a low oxygen shutoff activate on their own. Both matter most in enclosed spaces with limited airflow.
You get only two heat settings: 4,000 or 9,000 BTU. There is no thermostat to hold a target temperature. You switch settings by hand to adjust heat.
Propane adds ongoing fuel costs over time. For daily indoor use, electric heaters cost less to run. This heater pays off most where no power outlet exists.
At $79.99, it heats up to 225 sq ft. That covers a garage bay or a medium workshop. It is a strong match for cord-free, portable heat needs.

- Two heat settings give you a choice of 4,000 or 9,000 BTU per hour.
What Could Be Better

- Coverage area of 225 sq ft falls below the 300 sq ft category average.
- Propane fuel adds ongoing operating cost beyond the $79.99 purchase price.
