Your car might take a while to warm up on its own, but at least you can accelerate your own comfort with the COMFIER Massage Seat Cushion with Heat, which looks to live up to its name. With three heating pads and two heat level settings, it promises to start warming you up within a minute, helping to ease the frigid feeling of getting into a half-frozen vehicle.

And that’s not all. Thanks to 10 vibrating motors dispersed throughout the back and seat of the pad, you’ll also get a nice massaging feeling while you warm up and drive.

It has three built-in heating pads that cover the back and seat, with optional auto shut-off timers.

Meanwhile, the six vibration motors provide a massaging feeling to your upper and lower back, hips, and thighs, with five different massage mode settings and four intensity settings.

AmazonBasics 500-Watt Ceramic Small Space Personal Mini Heater


What We Like
  • Great value

  • Compact size

What We Don't Like
  • Modest heating power

Amazon’s AmazonBasics line delivers simple, common electronics typically at a lower price than rival brands, and that’s true with the AmazonBasics 500-Watt Ceramic Small Space Personal Mini Heater. While not packed with a lot of power, this portable electric heater is great for warming up your surroundings in a pinch.

Ideal for use in an RV, this six-inch tall heater can be placed on a table or countertop to provide warmth to any small space. It has tip-over protection to automatically shut off if knocked over, and Amazon sells it in four different colors. For occasional heating needs in your RV, it’s a very affordable device to keep handy.

Best Defrosting

FERRYONE Portable Car Heater

FERRYONE Portable Car Heater


What We Like
  • Defrosts windshield

  • Compact design

  • 360-degree swivel mount

What We Don't Like
  • Not much power

A frosty windshield is one of the worst parts of coming back to a half-frozen car. Even if you can tolerate the frigid feeling inside your car, you might not be able to get moving for a while until the frost clears. Luckily, that’s where the FERRYONE Portable Car Heater comes in handy. This dash-mountable heater is designed to help clear your view in a hurry.

It plugs into a 12V lighter port and rapidly defrosts your windshield with a blast of hot air. At 150W, it’s not going to provide a ton of heat to warm up the inside of your car in a hurry, but this little device should be very handy for its intended task.

Best Shiatsu Heat Massager

Zyllion Shiatsu Back and Neck Massager with Heat

Zyllion Shiatsu Back and Neck Massager


What We Like
  • Strong shiatsu massage

  • Heats while it massages

  • Both car + home adapters

What We Don't Like
  • Could feel bulky in car seat

While those other massaging cushions stick with vibrating pulses to deliver relief, the Zyllion Shiatsu Back and Neck Massager has heavy-duty rotating balls that rotate as they work into your muscles. All the while, the balls optionally heat up, delivering warmth and comfort. It’s perfect for a long drive in the winter, warming you up while keeping you cozy and comfy.

Zyllion’s massager is a versatile option that can be used for the upper and lower back, plus it comes with both car and home plugs for use anywhere. It’s compact and affordable—a very helpful companion for your winter aches and pains.

What We Like
  • Massages and heats

  • Car and home adapters

What We Don't Like
  • Could be distracting for some

Here’s another shiatsu heat massaging option, albeit more targeted towards the upper back and heck. The Naipo Shiatsu Back and Neck Massager drapes around your neck, delivering relief as the heated shiatsu balls push and prod your muscles.

While a bit less versatile than the Zyllion massager, given its shape, it still delivers a lot of comfort as it both massages and heats you up in the process. Naipo includes both car and home power adapters so that you can use it anywhere, and it’s a good way to start winding down on a cold drive home—or get warmed up in a cool car in the morning.

Final Verdict

COMFIER’s Massage Seat Cushion with Heat is our pick for the best option for most car drivers, as it can warm you up safely and with little hassle, with the added benefit of vibration-based massaging as well. However, if you drive an RV or you’re looking for a small heater to defrost your windshield, we recommend the Caframo Heater. It provides up to 1500W and has overheating protection.

What to Look for in a Portable Electric Car Heater

Functionality - What do you need the heat for? Are you trying to keep an RV warm in the winter, warm your body with a heated cushion, or melt the frost on your windshield so that you can get going? There are heaters designed for each need.

Compatibility - Make sure your car can handle the 12V lighter port plug that many of these heaters use, otherwise you’ll need a car power inverter to plug in a traditional two-prong plug and draw power from your vehicle.

Price - Ultimately, a heater has to fit within your budget, so consider your needs and whether you want to shell out for something significant or just want something affordable. We have included a wide range of options on this list.

  • Do portable car heaters really work?

    As our article explains, while a portable car heater powered by the cigarette lighter outlet can't stand-in for the full heating system of your vehicle, a 12-volt heater wired directly to the battery with an inline fuse is much more capable. A universal heater that relies on coolant rather than an electric heating element is an even more powerful alternative, but they're expensive and difficult to install.

  • Can you run a propane heater in your car?

    No. Using a propane heater in your car, particularly with the windows closed, is a bad idea. Propane heaters not only produce propane exhaust but also generate a lot of water vapor/moisture; without proper ventilation, the available oxygen can be quickly exhausted. They also present a risk of fire.

  • Are portable car heaters safe?

    Used properly, the heaters on our list are extremely safe; many 12V heaters, for instance, have an inline fuse for safety. That said, most residential heaters, even portable ones, aren't designed for or safe to use in your vehicle.
