Are there any heaters that run on batteries?

Yes, battery-operated heaters exist. They aren’t as popular as electric and gas heaters, which is why you’re perhaps bamboozled. Also, these heaters aren’t very powerful, which partly explains why they aren’t common.

However, for emergencies, the portability of a battery-powered heater could be just what you need. They don’t need to be plugged into an electrical outlet or the natural gas line neither do you need to refill a gas tank every few weeks. All you need is a fresh pair of batteries, and you’re ready to go.

This guide highlights some of the best battery powered heaters that run on batteries based on factors such as cost, heating capacity, and other features. We later also discuss what to look for in a non-electric heater.

Top 10 Heaters That Run On Batteries Comparison Table

How Battery Powered Heaters Work?

Battery-operated heaters are essentially hand and body heaters designed to keep you (as a single individual) warm. Many can keep your body at 100°F for up to 8 hours or even longer. A good number are also car heaters that you turn on to keep the can interiors warm for a given period.

Car and body/hand battery-powered heaters are resistance heaters. They use electric current to generate heat. The current passes through a resistance wire. The resulting resistance to electrical flow creates heat. 

However, it’s very little heat. While a standard electrical heater can produce an equivalent of 40,000 BTU or higher, a small car battery heater only generates about 500 BTU at 12 volts/20amp.

For reference, you need about 40BTU per square foot. It means that a battery-powered car heater is only effective over about 10 sq ft. or a 3 x 3-foot space. 

Combination battery-gas heaters, however, burn fuels to produce heat. These are gas heaters that use batteries for a few functions. 

Types of Battery-Operated Heaters

There are several categories of battery-operated heaters. The following are some of the most notable categories;

Battery-Operated Car Heaters

Battery-operated car heaters are small, portable units used in cars. They are technically the biggest battery-operated heaters you’ll find. 

The units plug directly into the vehicle’s cigarette lighter or 12v outlet and run straight off the car’s battery. As a result, you don’t need to buy a new battery. This makes the heaters even lighter and incredibly lightweight.

Indeed, most are made of plastic and weigh only a few ounces. Depending on the build quality, heat output, and other features, it can cost anywhere between $30 and $50, with others costing as much as $100+. 

These heaters can prove incredibly useful on a cold morning. Aside from adding a few BTUs worth of warmth to your car, they can also help defrost the windscreen. Above all, they’re a worthwhile option if you can’t afford a car heating system.

Battery-Operated Hand and Body Warmers

Battery-operated hand and body warmers have been around slightly longer than the car-warming models. Many hunters, fishers, and other people who spend a significant amount of time in the outside cold have long taken advantage of the warmers to keep warm.

Unlike the car heaters, they don’t use car batteries. Instead, they use smaller batteries ranging from AAA to 9-volt types to generate just enough heat to keep your hands and feet warm. It’s worth noting that you need multiple such heaters to keep the various parts of the body warm. The majority tuck easily into socks and hand gloves. 

Most of these heaters can continue producing heat for five or more hours on just one battery, making them incredibly effective and affordable. What’s better – some models are chargeable via USB! This means that you can charge the unit and only carry a few batteries along for emergencies. 

Combination Battery-Gas Heaters

The most common “battery-operated” heaters, combination battery heaters aren’t really battery operated. They depend on a small battery that powers the ignition and fan. The heat, however, comes from a different fuel source, usually gas, mostly propane. 

The use of gas allows these heaters to produce a lot more heat. The majority can put out as much as 1,500 watts, equivalent to about 5,200 BTU. Most of the products reviewed in this guide belong in this category.

Factors to Consider when Shopping for a Battery Powered Heater

Since battery-powered heaters aren’t very common, you may be tempted to pick any that comes your way. That’s not a very good idea. We recommend that you consider the following five factors;

  • Average heating duration: This applies to models that work on dedicated batteries. How long does the battery last? If it’s a rechargeable model, how long does the battery last on a full charge? Some of the best models last up to 13 hours of continuous use. 
  • Temperature settings: Can you change temperature settings? A great battery-operated heater allows you to adjust the heat/temperature settings as you wish. Additionally, consider the number of heat settings available. 
  • Multi-function capabilities: The best battery-operated heaters are designed for multi-function. Many car-battery-operated heaters, for instance, also function as car fans and even support phone charging. A few hand warmers also support phone charging.
  • Built-in safety measures: This is very important. For one, the heat coming from the heater shouldn’t be too much. Otherwise, it creates a burn risk. Many of the units implement auto-shutoff in case of overheating for safety reasons. 
  • Warranty/return policy: Finally, a few considerate manufacturers offer warranties and even allow returns in mechanical failure. It’s another thing you want to consider seriously. 

Summary 

Though not very common, battery-operated heaters are a great heating option for people who spend a lot of time outdoors, even in the freezing winter weather. These small devices, some handheld and others installable inside the case deliver enough heat to keep you warm for hours. They are also inexpensive, so you don’t need to worry about the budget. 

If you feel you’d benefit from a little extra heat out there in the cold, buying one of these should be a no-brainer.
