Mr. Heater Portable Buddy Heater MH9BX
This model is a portable radiant propane heater rated 4,000–9,000 BTU and designed for indoor-safe use in well-ventilated spaces. It’s intended for spot heating areas up to about 225 square feet using infrared-style radiant heat to warm objects and people directly rather than heating all the air.
- Powerful Radiant Heat: Adjustable BTU settings for variable heat output.
- Improved Safety Features: Tip-over safety switch and an audible engagement when disturbed.
- Reliable Ignition: Piezo igniter for match-free startup.
Considerations: This heater requires propane cylinders and should be used following manufacturer ventilation guidance. It provides immediate, localized warmth and is a common choice for outages where fuel is available and indoor use is permitted by local codes.
VESTA Self-Powered Camping Indoor/Outdoor Heater & Stove
The VESTA offers a two-in-one design functioning as a compact heater and a stove. It operates without electricity by using canned heat as fuel, intended for indoor use per the product claim and suitable for heating areas up to about 200 square feet.

- No Power Needed: Runs on canned heat canisters — up to three simultaneously for higher output.
- Safe For Indoor Use: Marketed for indoor operation when used according to instructions.
- Multipurpose: Allows cooking and heating from the same compact unit.
Considerations: Fuel supply logistics (storing canned heat safely) and ventilation remain important. This unit is useful where electricity is absent and a small, portable solution for warmth and basic cooking is needed.
Dura Heat EUH1465 Electric Forced Air Heater
The Dura Heat EUH1465 is a 1500W electric forced-air PTC ceramic heater built with a rugged steel body and a pivoting base for directional heating. It suits garages, workshops, or rooms where rapid warm air circulation is desired.
- Powerful Forced Air: 1500W output provides fast warm-up.
- Durable Construction: Rugged steel housing for heavier use.
- Versatile Settings: Heat and fan-only modes for multi-season use.
Considerations: This product requires AC power. For outages, pairing with a suitable inverter-capable power station (pure sine wave) is necessary to run safely and effectively. Evaluate run-time and watt limits when combined with backups.
OUPES Exodus 1200 Portable Power Station
The OUPES Exodus 1200 is a 992Wh Li-ion portable power station with three 1200W pure sine-wave AC outlets (3600W surge), USB-C PD, and multiple ports. It’s positioned for powering high-draw devices during outages, including small electric heaters within its continuous wattage limits.

- High Capacity: 992Wh battery and 1200W continuous AC output.
- Surge Capability: 3600W peak for starting loads.
- Multiple Ports: Charge and run several devices simultaneously.
Considerations: When using to power electric heaters, confirm the heater’s continuous wattage demand. A 1500W heater exceeds the 1200W continuous rating, so select lower-wattage electric heaters or use in conjunction with energy-efficient ceramic or PTC units. Solar recharging options can extend runtime during prolonged outages.
HUGO Battery Backup For Tankless Hot Water Heater & Gas Appliances
The HUGO backup system uses LiFePO4 battery technology in NEMA-rated enclosures to provide dedicated power for tankless hot water systems and gas appliance controls during outages. Models offer different capacities (L30, L50) and include a flow sensor to allocate power only when water use is detected.
- LiFePO4 Battery: Long-life chemistry with high cycle stability.
- Weatherproof Enclosure: NEMA4 / IP54 allows indoor or protected outdoor installation.
- Flow-Activated Output: Conserves battery by supplying power only when water flow is sensed.
Considerations: This product targets maintaining hot water and gas appliance control electronics rather than space heating. It’s a specialized backup for households relying on tankless systems during outages.
Buying Guide: How To Choose A Heater For Power Outages
Selecting the right heater for an outage depends on power availability, home layout, safety requirements, and fuel logistics. The sections below outline key factors and comparison perspectives to aid decision-making.
Power Source And Availability
- Fuel-Based Heaters: Propane, canned heat, or wood stoves function without grid power and are often the most reliable for extended outages. Ensure proper storage and ventilation, and check indoor-safe ratings.
- Electric Heaters With Backup Power: Electric ceramic or infrared heaters require inverters or power stations. Match the heater’s continuous wattage to the power station’s continuous output and allow headroom for safe operation.
- Dedicated Battery Backups: For specific needs (e.g., tankless hot water), purpose-built LiFePO4 systems offer reliable, long-lasting power for designated appliances.
Safety Considerations
- Indoor Use Certification: Verify whether a fuel heater is rated for indoor use and follows CO and ventilation requirements.
- Tip-Over And Overheat Protections: Look for automatic shut-offs and robust safety interlocks to reduce fire hazards.
- Carbon Monoxide Risk: Any combustion appliance demands a CO detector in the living area. Never use outdoor-only units indoors.
Heat Distribution And Coverage
- Radiant vs. Convection: Radiant heaters (infrared, propane radiant) heat objects and people directly and can feel warmer faster in localized spots. Convection and forced-air heaters circulate warm air to heat entire rooms but may take longer.
- Square Footage Matching: Compare heater BTU or watt ratings to the space you need to heat. Manufacturer guidelines for square footage are useful starting points.
Run Time And Fuel Logistics
- Fuel Storage: Plan for safe storage and availability of propane cylinders, canned heat, or other fuels for the expected outage duration.
- Power Station Runtime: Convert heater wattage to amp-hours and compare with battery capacity. For example, a 500W heater running from a 1000Wh station will deplete that station in about two hours not accounting for conversion losses.
- Recharging Options: Solar recharge or generator recharging can extend electric backup runtime; confirm compatibility and recharge rates.
Portability And Installation
- Portable Units: Small propane radiant heaters and canned-heat stoves are easy to move and deploy in emergency refuges or bedrooms.
- Fixed Or Semi-Permanent Backups: Battery backups for tankless systems often require wiring and professional installation; they’re less portable but maintain critical functions.
- Durability: For garage or workshop use, rugged steel electric heaters can tolerate rougher conditions.
Compatibility And Electrical Ratings
- Pure Sine Wave Requirement: When pairing heaters with power stations, choose an inverter that outputs a pure sine wave to protect motors and electronic controls.
- Start-Up Surge: Account for heater surge current at startup. Choose a power station with sufficient surge capability if required.
- Continuous vs. Peak Ratings: Don’t exceed the continuous wattage rating of a power station even if it shows a higher surge rating.
Redundancy And Layered Strategies
- Multiple Options: Combining a fuel-based portable heater for primary heat with battery-powered lights and a power station for essential electric devices gives flexibility.
- Zone Heating: Heat only occupied rooms to conserve fuel and battery resources rather than attempting to heat the entire home.
- Non-Heating Essentials: Maintain lighting (lanterns) and communications (charged phones) as part of the outage plan.
Comparison Perspectives
- Immediate Warmth: Propane radiant heaters and canned-heat stoves provide near-instant, focused warmth for occupants in a room.
- Whole-Room Comfort: Forced-air electric heaters paired with sufficient backup power are better for circulating warm air across a room.
- Specialized Needs: Battery backups for tankless hot water ensure hot water availability, which is a different benefit than space heating but important for comfort and sanitation.
- Long-Term Outages: Fuel availability and recharge options (solar/generator) determine sustainability over extended periods.
Use the above criteria to match a heater or backup system to your home, family size, and outage risk profile. Safety, run-time calculations, and proper ventilation are the most critical factors when deploying any emergency heating solution.
