Best Overall: COMFIER Massage Seat Cushion

Buy on Amazon

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 five programmed settings and three intensity levels, so between the heat and the massaging capabilities, it shouldn’t take long before you get comfy for your commute.

Best for RVs: Caframo Limited True North Space Heater

Looking to fill your RV with heat and minimize your reliance on propane? Caframo Limited’s True North Space Heater provides plenty of warmth for your camper, with five heat settings to suit your needs up to a maximum wattage of 1500, plus a dual overheat protection system to avoid dangerous overheating.

Customer reviews point to a powerful blast of heat that circulates quickly through your heater and generates only noise, particularly on the lower settings. It’s still pretty compact at 9.25 x 4.4 x 4.4 inches and just over 5 pounds, with a metal and plastic look that works well in an RV and can be easily mounted to a wall or ceiling.

Runner-Up, Best Heat Massager: Snailax Massage Car Seat Cushion

SNAILAX’s Massage Car Seat Cushion is a less robust massaging option, but it’s also more affordable as well. This massage cushion, which plugs into your car’s lighter port, both heats and massages to get you warmed up and comfortable in a hurry. 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.

Best Budget: AmazonBasics 500-Watt Ceramic Small Space Personal Mini Heater

Buy on Amazon

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

Buy on Amazon

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.

Runner-Up, Best Defrosting: ROYADVE Portable Car Heater

Buy on Amazon

Here’s another option for clearing the frost off of your window in the winter. ROYADVE’s Portable Car Heater is very similar to the one above, as it plugs into a 12V lighter port and provides 150W of heat. With three openings, it disperses the warm air directly to your windshield, quickly clearing the view so that you can get going.

Like the FERRYONE heater, it also can be used in warmer weather to remove fog from your windshield. Given the maximum wattage, the overall impact to your car cabin’s temperature might be minimal, but it should excel at its stated focus.

Best Shiatsu Heat Massager: Zyllion Shiatsu Back and Neck Massager

Buy on Amazon

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.
