Overview

The Portable Buddy is Mr. Heater's smallest radiant propane heater, running off a 1 lb cylinder for camping, tailgating or job site breaks. Two settings give 4,000 or 9,000 BTU/hr, enough for a tent or roughly 225 square feet, indoors or out.

Its main limit is runtime: a 1 lb bottle lasts about 5.4 hours on low and 2.4 hours on high, so anyone heating a space for a full evening will want spare cylinders or the separate hose kit that lets it run off a 20 lb tank. Mr. Heater also restricts warranty coverage to its own accessories.

  • 4,000 or 9,000 BTU/hr radiant heat
  • Heats up to about 225 square feet
  • Runs 2.4-5.4 hours on a 1 lb propane cylinder
  • Low oxygen safety shutoff

Who it's for

Campers, hunters, tailgaters and anyone needing quick radiant heat in a small enclosed space are the target buyer, not anyone heating a garage, basement or living room; those need a larger convection or tank top model.

Pros and cons

Pros
  • Two heat settings for camping or outdoor use
  • Approved for both indoor and outdoor use
  • Runs on cheap, widely stocked 1 lb cylinders
  • Automatic low oxygen shutoff
Cons
  • Small 1 lb bottle only lasts 2.4-5.4 hours
  • 225 sq ft ceiling limits it to small spaces
  • Locked to Mr. Heater's own accessories for warranty coverage

Performance notes

The radiant burner throws heat directly rather than warming air first, so it responds fast in open or ventilated spaces. A built-in low oxygen safety system shuts the unit down before oxygen levels drop too far, and the housing is built from self-extinguishing materials for tip-over safety.

Frequently asked questions

Yes, it is designed and approved for both indoor and outdoor use, with a low oxygen sensor that shuts it off if oxygen levels get low.

About 5.4 hours on the low, 4,000 BTU setting and 2.4 hours on the high, 9,000 BTU setting.

Can it connect to a 20 lb propane tank?

Not out of the box; it ships for 1 lb cylinders and needs a separate Mr. Heater hose accessory to run off a 20 lb tank.
