Best Portable Battery-Operated Heaters For Home and Car

Lately, I noticed more and more people were searching for portable battery operated heaters to use in their homes and cars.

Unfortunately, there are not many battery operated heaters out there. Trust me, I looked high and low!

It is probably because the power needed to generate heat for larger areas would be intense against a small battery.

In this article I have a couple of small battery operated heaters, as well as a few portable non-battery operated heaters. As new products come along – I will be sure to add them if they seem to be solid choices!

One battery, no matter how powerful it is, does not provide enough energy to heat, even for just a small area in your bedroom or bathroom.

So, a battery-operated heater could be a nice idea, but unfortunately, it would not work for as long as you need it to. Yet, a battery can power smaller heating devices, such as hand warmers. Most of them are also comfortable to take with you on long walks or camping trips because of their little dimensions. The battery-operated heater also makes it easier for you to bring it up anywhere. They are one of the essential supplies that you must have whenever there is no electricity during severe weather.

Choosing The Best Portable Heaters

I checked a few factors before deciding which options to include in this article. Of course there is no way I could test each one, but I did take some time to research what others are saying about these models.

And no, I did not just look at the Amazon reviews. I am smarter than that and know many of those reviews are paid for! I checked forums, Reddit, Quora, and did some super-sleuthing to help you make an informed decision.

Here are some of the most important criteria to be taken into consideration when choosing the top five portable battery-operated heaters:

  • Positive online reviews from customers and experts;
  • Length of heat after a battery charge;
  • Length of time for heater to reach optimal temperature;
  • Heating and temperature level choices;
  • Built-in safety measures;
  • More uses for the heater (fan for car heaters or phone charger for hand warmers, etc.);
  • Manufacturer repair/return policy and customer service;
  • The inclusion of an adapter or cord;
  • User manual or instructions.

While not as important, I did also take a look at whether accessories, such as a pouch or lanyard (to hold the device around your neck), were included. These kinds of features can be a great addition to depending on your specific needs.

5 Best Portable Battery Operated Heaters

Below is the most current list of portable heaters that are battery operated for you to consider. This post will be kept updated annually as products change and new competition comes into the market.

So, let’s start with our first favorite!

Innopaw Battery Operated Hand Warmers

Lot’s of great feedback on these rechargeable hand warmers!

One of the cool things on this product is that you can use them as two separate hand warmers – or connect them together and have one larger warmer.

View On Amazon

Hand warmers are great for outdoor activities, such as hunting, skiing, hiking, or fishing. This particular battery-operated heater features 3 heat settings and can heat as quickly as 3 seconds.

It comes with a 10000 mAH battery and can also be shared with your power bank with the 2 input ports including a Micro and USB C. So not only can it heat your hands, but you can charge your phone!

Some say the shape was a bit uncomfortable for their hands, so that is something to consider – but overwhelmingly people are pretty happy with this product.

Letouch Rechargeable Hand Warmer and Power Bank

No longer available!

This hand warmer is shaped like a pebble and is easy to carry during the coldest days. You can use this device to warm your hands while fishing, hunting, skiing, or camping.

First of all, the Letouch hand warmer offers three temperature levels to provide constant heat to both hands. The three temperatures available: are 104-113 degrees F, 113-122 degrees F, and 122-131 degrees F.

Moreover, the device heats up in three seconds, and shuts off automatically after an hour, to save the battery. Remember that for the 7800mAh option, you need to charge the battery for two to three hours. On the other side, you only have to charge the battery for between 1 and 3 hours for the less powerful option.

The pebble design not only warms your hands, but it helps soothe pain from arthritis, Raynaud’s Disease, and menstruation. Also, the product’s structure has a special safety system that protects it against overcharging, overheating, and short circuits. Not to mention that the battery is manufactured using environmentally friendly polymer, so if you are an eco-lover, this is the option for you.

As a customer’s advice: you should put the hand warmer on a cloth pouch to avoid burns on delicate skin. Also, you should avoid charging and using the heater at the same time.

The Letouch Hand Warmer has a 12-month manufacturer’s warranty. The unit comes with a cloth pouch, USB cable, instruction manual, and lanyard.


  • An outdoor photographer commented that the Letouch hand warmer heats up quickly and will not drop below 120 degrees for four hours.
  • Online buyers returned this product with 29 fewer percentages than they did regarding similar products.


  • Avoid charging and using the heater at the same time.

AmazonBasics 500-Watt Ceramic Mini Electric Space Heater (Not Battery Operated)

Not battery operated, but very portable and easy to use in an emergency situation in your home.

This compact personal space heater is small enough for tables or desktops and features efficient ceramic coils that heat up in seconds. The heater is also available in 4 colors to custom-match your decor.

View on Amazon

Even though it is quite small, when used in close quarters, or even when left in an average-sized bathroom, this 500-watt space heater can leave the air feeling drier and significantly warmer from wall to wall.

Also, AmazonBasics products are not known for being equipped with state-of-the-art technology. Their simplicity is the main source of their extremely budget-friendly price tags. This 500-watt space heater is no different. It does not come with remote control, a thermostat, a built-in timer, oscillation, or overheat protection. This is a straightforward, plug-and-go space heater with a non-heating cord and an on/off switch.


  • Includes tip-over protection for extra safety.
  • Ideal for small spaces, at home or at the office.
  • Last but not least, the heater is eligible for a return, refund, or replacement.


  • The space heater won’t be so effective in a larger room.
  • One thing that’s missing in the AmazonBasics 500-watt Space Heater is a cool-to-the-touch grill. What this means is that the metal grill will become almost as hot as the coils which can become a real fire hazard while standing on its base.

OCOOPA Hand Warmers

With over 27K almost 5 star ratings, these battery operated warmers are worth having on hand for your next emergency.

It is compact, affordable and can keep you warm for roughly 4-8 hours depending on your heat level!

View On Amazon

Three levels of heat that range from 95 degrees – 131 degrees offers a range everyone will be comfortable with. And the 5200mAH lithium battery is rechargeable and offers approximately 4-8 hours of heat time on the lower level.

It will take about 2-3 hours to fully charge so it is important to make sure you keep it charged so you are ready when you need it. It is important to note that the charging station does come seperately and be sure to check if you are ordering the on-pack or two-pack!

  1. For the coming winter season, these heaters seem a great option. I love Energy Fluxe and going to get it for me. I think it’s relatively better when compared to others.
