Our Verdict

This heater puts out 12,000 BTU per hour. It warms spaces up to 300 sq ft. That covers a large hunting blind, small cabin, or campsite.

The price is $29.99. Very few heaters offer this BTU output at that cost. The price per square foot comes out to just $0.10.

It runs on propane, so you need fuel on hand. Propane canisters add to your total running cost over time. Electric heaters do not carry this extra expense.

Two safety features protect you during use. A tip-over shutoff cuts the heater off if it falls. A low-oxygen sensor shuts it down if air quality drops too low.

There is no thermostat, timer, or remote control. You adjust heat with a simple Hi-Low knob. This heater is built for rugged outdoor use, not smart home features.

$29.99 purchase price
