10 Best Camping Tent Heaters 2025 in the United States

The Mr. Heater Portable Buddy Heater MH9BX is a versatile propane heater ideal for camping tents, workshops, patios, and more. It offers adjustable heat output ranging from 4,000 to 9,000 BTUs, capable of effectively warming spaces up to 225 square feet. One of its key strengths is its advanced infrared technology, which provides direct, sun-like warmth to people and objects, making it very efficient in its heating capacity.

The heater is equipped with a reliable Piezo igniter, making it easy to start without the need for matches or lighters. Additionally, it has a fold-down handle, which enhances its portability, and a swivel regulator for easy connection to propane cylinders. It can run for up to 6 hours on the low setting with a 1 lb. cylinder, making it fairly fuel-efficient for its size and heat output. Safety is a top priority with this heater, as it includes a tip-over safety switch and a low-oxygen shut-off system, which ensures it shuts down in unsafe conditions.

Its weight of 8.53 pounds and compact dimensions make it easy to carry and use in various settings. However, one downside might be the limited runtime on the high setting, lasting only 3 hours on a 1 lb. propane cylinder, which may require frequent refueling during extended use. Additionally, while the heater is designed for quiet operation, some users might find the noise level noticeable in very quiet environments. Nevertheless, it stands out as a reliable and efficient choice for those needing portable heat in small to medium-sized spaces.

The Amazon Basics Ceramic Space Heater is a compact and lightweight option designed primarily for indoor use, such as in your home or office. Measuring 5.8 x 3.4 x 6 inches and weighing only 1.4 lbs, it is easy to transport and can be placed on tables or desks without taking up much space. This heater uses ceramic coils to provide fast and efficient heating at 500 watts, making it suitable for quickly warming up small areas. It includes safety features like Tip-Over Protection, which automatically shuts the heater off if it gets knocked over, enhancing its safety for use around children or pets.

However, it's important to note that the heater is designed for indoor use only, which may limit its effectiveness in a camping tent setting where outdoor conditions can be more variable. Additionally, with a heat output of 500 watts, it may not provide sufficient warmth in very cold temperatures or larger spaces typically associated with camping. The heater operates quietly, which is a plus for maintaining a peaceful environment. It is powered by electricity, meaning you will need access to a power source. This could be a drawback if you are camping in an area without reliable electricity.

The Amazon Basics Ceramic Space Heater offers portability, quick heating, and essential safety features, but its indoor-specific design and reliance on electricity might not fully meet the needs of all camping scenarios.

One of its standout features is the automatic low oxygen shut-off system, which ensures safety by turning off the heater when oxygen levels are low. Additionally, it has a tip-over switch that automatically shuts off the heater if it is accidentally knocked over, adding an extra layer of safety.

The heater is easy to operate with simple on/off buttons and works with a 1-pound disposable propane cylinder, though the cylinder is not included. Its continuous odor-free heating angle of 45 degrees is beneficial for consistent warmth distribution. Portability is a strong suit due to its lightweight design, weighing only 1 pound, making it easy to transport and set up. However, users must ensure adequate ventilation while using it, as the heater requires a minimum vent area of 4 square inches for safe operation.

The fuel efficiency is moderate, with a runtime of up to 5.6 hours at maximum BTU, which is reasonable for a camping trip or emergency use. On the downside, it is not suitable for use in moving vehicles or golf carts, limiting its versatility. Additionally, users should be cautious about using non-authorized accessories to avoid voiding the warranty. It is a reliable option for those needing a safe and portable heating solution for small spaces during camping or other outdoor activities.
