BLACK+DECKER Portable Space Heater

The BLACK+DECKER Portable Space Heater is a compact electric unit designed for room-to-room portability. The unit weighs about 2.8 lbs. and includes a built-in carry handle for easy movement inside an RV or between living spaces.
Heat settings include Low (750W), High (1500W), and a fan-only mode. The heater measures roughly 7.3″ x 6.3″ x 9.2″ and uses a 6-foot power cord. An adjustable thermostat lets the unit cycle to maintain a selected comfort level.
Electric heaters require a compatible RV electrical supply (shore power or generator) and draw from the RV circuit. For ventilation, electric units do not produce combustion gases, so they do not need venting but should not be obstructed and must be used on stable surfaces with clearances per manufacturer guidance.
Mr. Heater RV Buddy Radiant Heater

The Mr. Heater F232017 MH9BXRV Buddy is a portable propane radiant heater approved for indoor/outdoor RV use. Output ranges from 4,000 to 9,000 BTU, and the manufacturer cites coverage up to about 225 square feet, depending on insulation and ambient temperature.
Key safety features include auto shut-off on tip over, pilot outage, or low-oxygen detection. The unit is described as nearly 100% efficient for radiant heat, meaning it converts fuel to heat with minimal losses. The product notes operation limitations above 7,000 ft altitude where the unit may shut off without adjustment.
Propane heaters require allocated fuel storage, appropriate hookups, and functioning CO/combustible gas monitoring. The radiant nature provides fast localized warmth, but placement and manufacturer clearance recommendations should be followed to avoid surface heat issues.
GiveBest Portable Ceramic Heater

The GiveBest Portable Electric Space Heater is a compact ceramic model with two heat settings (1500W and 750W) and a cool fan mode for summer use. It includes thermostat control and cycles to maintain selected temperatures.
Safety systems listed include flame-retardant materials, overheat shutoff, and tip-over protection that cuts power if the unit is knocked over. The thermostat is described with a range to mimic target temperatures and will cycle automatically.
The unit’s small footprint and built-in carry handle make it suitable for smaller RV living areas where shore power is available. Electric ceramic heaters produce convective heat and are typically quieter than forced-fuel devices, but they draw continuous electrical current at rated wattage.
Dreo PTC Ceramic Space Heater

The Dreo Space Heater uses an advanced PTC ceramic element rated at 1500W. The design emphasizes quicker warm-up and enhanced air circulation through a “heat funnel” concept and a wider temperature control span.
Controls include a digital display, remote control, and a 12-hour timer. Safety features noted are tilt-detection, overheat protection, V0 flame-retardant materials, and an ETL-certified safety plug. Temperature control is described as precise, adjustable from 41–95°F in 1°F increments.
For RV use, the Dreo unit is suited where consistent electrical capacity is available. Digital controls and a timer support automated cycles to reduce runtime while maintaining set points. Confirm RV electrical panel limits before extended use at higher wattage settings.
Mr. Heater Massachusetts/Canada Approved

This Mr. Heater MH9BX version is specified as Massachusetts/Canada approved, meeting additional regulatory or certification requirements for those regions. Like the other Mr. Heater models, it provides 4,000–9,000 BTU and is intended for portable indoor and outdoor use.
Features include auto shut-off for tip over, pilot outage, and low oxygen conditions, and the same altitude operational limits over 7,000 ft. Certification differences may affect availability in certain jurisdictions and compliance with local codes or rental park rules.
This model is an option for RV owners in areas where stricter approvals are required, but it still requires adherence to propane handling, ventilation, and carbon monoxide detection standards for safe indoor operation.
Buying Guide: Choosing A Portable Heater For Your RV
Selecting a portable RV heater involves balancing power source, space coverage, safety features, and RV electrical or fuel constraints. The sections below break these considerations into practical comparison points.
Power Source: Propane Versus Electric
- Propane Radiant Heaters (e.g., Mr. Heater models): Provide high BTU output and fast localized warmth. They operate independently of the RV electrical system but require propane supply, proper hookups, and working CO/propane detectors. Many models include oxygen depletion sensors (ODS) and auto shut-off features.
- Electric Ceramic/PTC Heaters (e.g., BLACK+DECKER, GiveBest, Dreo): Draw shore power or generator power. They avoid combustion gases, eliminating the need for venting. Ensure the RV’s electrical system (15A/20A/30A/50A) can supply the heater at rated wattage without tripping breakers or overloading outlets.
Heating Capacity And Coverage
- Compare BTU ratings for propane heaters and wattage for electric units. A 1500W electric unit is typically suitable for small cabins or single RV zones, while 4,000–9,000 BTU propane units reach larger open spaces.
- Actual coverage depends on insulation, ceiling height, and outdoor temperatures. Manufacturers’ square-foot estimates assume average conditions; colder climates or poorly insulated rigs reduce effective coverage.
Safety Features And Certifications
- Look for tip-over protection, overheat shutoff, and an oxygen depletion sensor (ODS) on combustion units.
- Certifications (ETL, CSA, or specific state approvals) indicate compliance with safety standards. Some propane heaters have jurisdiction-specific approvals (e.g., Massachusetts/Canada) — relevant for buyers subject to local codes.
- Install and maintain CO and propane detectors in any RV where combustion heaters are used.
Ventilation, Installation, And Placement
- Combustion heaters need adequate fresh air and, in some installations, venting per manufacturer instructions. Follow clearances and avoid placing near flammable materials.
- Electric heaters should be placed on stable, level surfaces with unobstructed air inlets/outlets. Avoid running extension cords unless rated for the heater load.
- Consider storage and portability: built-in handles, weight, and footprint affect where a heater can be stowed when not in use.
RV Electrical Capacity And Power Management
- Confirm the RV’s available power: a 1500W heater on a 120V circuit draws ~12.5A. On a 15A circuit, that limits other loads. On 30A and 50A systems, balance total load across legs.
- Using a generator or shore power is common; verify generator capacity and runtime if relying on it for heating.
Altitude And Environmental Limits
- Some propane models include altitude-related shutoff or require regulator adjustments above ~7,000 ft. Check manufacturer guidance if camping at high elevations.
- Cold-start performance varies: radiant propane units often heat quickly, while electric convection units provide steady background warmth.
Heat Distribution: Radiant Versus Convective
- Radiant Heat warms objects and people directly; it feels immediate and is efficient for spot heating.
- Convective/Forced-Air Heat warms room air and supports more even distribution; larger RV interiors may benefit from convective circulation or multiple units.
Controls, Thermostat, And Automation
- Digital thermostats, timers, and remote controls improve comfort management and can reduce runtime. Accurate thermostats (1°F increments) support tighter control and potential energy savings.
- Manual two-setting units are simpler but may run longer to reach comfort levels.
Operational Costs And Fuel Availability
- Propane cost and availability vary by location; propane heaters can be economical for off-grid use. Electric heaters’ operating cost depends on shore power or generator fuel consumption.
- Estimate typical run-hours and local energy/fuel rates to compare ongoing costs.
Noise, Maintenance, And Durability
- Ceramic and PTC heaters are typically quieter; some forced-propeller units produce audible airflow. Radiant heaters are often silent except for pilot sounds on certain models.
- Maintenance for propane units includes checking fittings, hoses, and pilot/ignition systems. Electric units require minimal maintenance but should be cleaned of dust and debris periodically.
Regulatory And Park Policies
- Some campgrounds or RV parks have rules about open-flame appliances, indoor combustion heaters, or propane storage. Verify local policies, fire codes, and insurance requirements before using a portable heater indoors.
Comparative Perspectives To Match Needs
- If you need off-grid heating, propane radiant heaters offer independence from shore power and quick spot heat for sleeping areas.
- For shore-powered RV stays with a focus on continuous, even warmth and digital control, electric PTC/ceramic heaters add convenience and no combustion risks.
- If traveling across jurisdictions, confirm certifications and approvals (e.g., Massachusetts/Canada versions) to ensure compliance with regional requirements.
