Sojoy 12V Heated Smart Multifunctional Travel Electric Blanket

Sojoy 12v Heated Smart Blanket

Buy from Amazon

If you’re looking for a low priced 12V heated blanket for your RV this winter, this model by Sojoy has all the features you need.

At 60 by 40 inches, this heated blanket is a good size, large enough for two persons. Made from a cozy polyester fleece it will also help to keep you warm even when it is not switched on, perfect as an extra layer of insulation.

For ease of use and improved energy efficiency, this model has a thermostat and three levels of heat control. Capable of reaching temperatures up to 110 degrees Fahrenheit, this 12V electric blanket draws just 3 amps on its lowest setting, or 3.7 on high. It is also equipped with a timer that can be set at 30, 45 or 60 minutes to ensure that you won’t drain your vehicle battery, especially helpful if you fall asleep cozy and warm without turning it off.

The 73-inch cord is a decent length for use in your RV cab while on the road and you can use standard conversion leads with your deep cycle batteries or generator power. You could also just use an extension to reach from your dash to your sleeping area. Fast to heat up and secure (thanks to its auto shut off) this 12V electric blanket makes a great choice to take the chill off those cold winter nights so you can RV in comfort all year round.

Stalwart Electric Heated 12 Volt Fleece Blanket

Stalwart Heated Automotive Blanket

Buy from Amazon

Warm up on your next RV road trip with the Stalwart Electric Heated 12V Fleece Blanket.

Its longer-than-average 96-inch power cord makes it a good choice for warming your cab or tow vehicle seats and provides extra distance when using it with other power sources or a 12V extension to reach your sleeping quarters. It’s also a lightweight, warm choice that comes complete with its own storage case for summer.

Soft and fleecy, this polyester blanket will help keep you cozy even when it’s not plugged in. At 59 by 43 inches, it’s a decent size and it gives out a reasonable amount of heat. Just bear in mind that there is no high or low option to adjust the heat level with this particular blanket, that draws around four amps.

The main disadvantage of this model is that it has no timer, which could be what you’re looking for if you want a heated blanket that stays on all night. To stop it, you have to unplug it as it doesn’t have any controls, which means you’ll have to get out of bed.

However, it is available at a low price and is ideal for warming up your cab seats as it heats up really fast. It also makes a great piece of emergency kit to have on standby, but we would rate it as less suitable for regular bedtime use.

Roadpro 12-Volt Polar Fleece Heated Travel Blanket

Roadpro 12 Volt Polar Fleece

Buy from Amazon

First off, this 12V electric heated blanket by Roadpro is a good size at 58 by 42.5 inches. So, if you’re part of a couple, a family or simply prefer a large blanket, then this model could be the one for you.

Its warm fleece fabric will help you and your passengers to stay cozy even when it’s not plugged in. But in chilly conditions, you can switch it on to enjoy the temperature range of 70-104 degrees Fahrenheit.

While there are more energy-efficient models available, with its 4.6 Amp draw (55 watts), it shouldn’t run down your battery too much when used sparingly. However, the main disadvantage of this particular model is that it has no control panel or auto shut off. While this may be preferable for some people, it means you’ll have to unplug it in order to switch it off. Therefore, if you don’t wake up and get out from under the covers into the cold, you could risk having a flat RV battery in the morning.

This blanket is a good overall choice and will keep you warm on the road, but if you are specifically looking for an electric blanket for sleeping in your RV, we recommend taking a look at some of our other 12V travel blanket recommendations that come with timer functions.

Otherwise, if you are looking for a heated blanket you can leave on for as long as you like, this could be your ideal choice.

Car Cozy 2 – 12-Volt Heated Blanket

Car Cozy 12 Volt Heated Travel Blanket

Buy from Amazon

The Car Cozy 2 12-Volt Heated Blanket is made from soft-to-the-touch polyester fleece for extra warmth and comfort whether you are using it plugged in or not. It warms up in just minutes and at 58 by 42 inches, it’s large enough for two people.

One of the main advantages of this particular 12V heated blanket is its patented safety timer, so you won’t have to worry about dozing off with it plugged in. Simply set the timer to 30 or 45 minutes and it will automatically cut off when the time is up, reducing the chances of you inadvertently using up all of your battery power. Alongside its reset button and automatic temperature control, you can also check it is definitely on thanks to its handy LED power light.

With a fairly average draw of four Amps (48 watts) and an 84-inch power cord, this electric blanket is on a par with other top contenders. It heats up quickly, and thanks to its automatic cut out, provides a safe way to rapidly warm up your RV sleeping quarters.

While the Cozy Car 2 is a little more expensive than some of its competitors, its safety features provide added peace of mind, making it well worth the few extra dollars.

Maxsa Innovations Large Heated Blanket

Maxsa Large Heated In-Vehicle Blanket

Buy from Amazon

This 12V heated blanket by Maxsa Innovations is made from a warm polyester fleece material. Measuring 41 by 57 inches, it’s a fairly standard size, suitable for up to two persons.

Thanks to its automatic timer, you won’t have to worry about accidentally leaving this blanket on overnight and draining your battery. Choose from 30 or 45 minutes, once you press the power button the timer starts counting down and powers off automatically. This blanket also has a built-in 10 amp fuse to ensure that it won’t draw too much current and overheat – of utmost importance as RVs tend to incorporate a higher concentration of flammable materials than regular brick and mortar homes.

Drawing approximately 4 amps (48 Watts), this heated blanket shouldn’t deplete your battery reserves. While it does take 10-15 minutes to heat up fully, once it has warmed up it holds the heat well, making it a great energy-saving choice. If you’re planning on using it up front or in your tow vehicle, its 84-inch power cord is plenty long enough. You could also use it to heat up your bed with an extension lead or conversion connector.

In spite of its slightly longer than average heat up time, this 12V heated blanket is worth the extra money given its electric controller, built-in safety fuse and automatic cut off timer, as well as its ability to keep you cozy warm long after it has turned itself off.

Although this particular model is at the higher end of the price range, it does provide a number of important safety features and comes complete with a zippered storage pouch.

Camco Polar Fleece Heated Blanket

Camco Polar Fleece Heated Blanket for Cars

Buy from Amazon

Although automatic shutoffs are a great safety feature that can save your battery, not everyone wants a heated blanket that turns itself off. If you’re searching for a model with a manual shut off, then check out this version by Camco.

Measuring 43 by 59 inches, this blanket is big enough for two people or can wrap around one with plenty of overlap. It has a heavy-duty, 84-inch power cord for connection to your dash, or other compatible 12V power outlet socket; so you can use it in your cab or to heat up your bed before you settle down for the night.

This electric blanket takes a while to get going and as it doesn’t have a timer, it will use more power than one with a timer and power-off function. In addition, this model also draws a slightly higher than average 5 Amps (60 Watts), so it will go through more power than some of the more energy-efficient ones that draw around three Amps. It’s also worth noting that this model does not have a choice of high or low heat settings.

Made from a soft fleece polyester fabric, this heated blanket will keep you comfortable and warm when you’re out on the road. While there are other models available with additional features and settings, if you’re looking for a good budget model with a manual shut off, this version makes a good all-round choice.

Schumacher 12V Heated Travel Blanket

Schumacher Heated Travel Blanket

Buy from Amazon

If you’re looking for a 12V heated travel blanket to take the chill out of your wintertime RVing, then this version by Schumacher could be what you are looking for. Before reading any further, bear in mind that this blanket has a manual shut off only and does not have a timer or heat level setting function.

That said, if you’re planning to use it during the day on the road, or if you want your blanket to stay on throughout the night, this model could be perfect for you. While there is no electric controller with this version, you can check that the blanket is switched on via the LED light on the plug. Once the blanket is connected to your cigarette lighter socket via its 64-inch cord, it will automatically maintain a steady temperature to keep you cozy during cold nights.

With its comfortable fleece fabric, this blanket is soft to the touch and makes a great seat warmer. However, it does take quite a while to heat up and it isn’t the most powerful of heated blankets. Therefore, if you really feel the cold, you may be better off with a model that produces more heat.

Drawing approximately 3.7 amps (45 Watts maximum), this heated travel blanket is fairly low powered. Even so, without a timer, you will need to ensure that you have sufficient power resources to avoid draining your battery.

On the whole, we think this manual shut off heated blanket is a good choice if you’re looking for a model that provides low-level heat over long periods of time.

Zone Tech Car Heated Travel Blanket

Zone Tech Car Heated Fireproof Blanket

Buy from Amazon

Whether you’re taking a winter RV trip as a family or a couple, this two-pack of 12V heated travel blankets is sure to be a popular choice. Measuring 56 by 40 inches, these blankets are a little smaller than your average-sized models. However, as it is a set of two, you won’t have to worry about sharing!

These cozy fleece blankets are easy to fold up neatly for storage as they use a special Far-Infrared Heating Technology. This means you won’t feel any lumpy wires and your blankets will radiate heat much more evenly.

The main advantage of these heated 12V blankets is their electronic controllers complete with buttons and a digital display screen. You can use the controller to power your blanket as required, so you won’t have to get out of bed to switch them on or off.

For extra comfort and potentially energy-saving usage, you can also adjust the temperature via the buttons on the controller. The screen displays the current temperature setting, which offers a maximum of 150 degrees Fahrenheit. This model also has an inbuilt 45-minute timer for additional safety, but once it powers off, you can simply turn your blanket back on from the control pad as needed.

Thanks to their impressive temperature control feature, these travel blankets make a good choice for RVing over winter months. Their cozy fleece fabric, easy operation controller and Far-Infrared Heating System make this twin heated travel blanket set an excellent choice.

Electrowarmth Twin Heated Pad

Electrowarmth Heated Mattress Pad

Buy from Amazon

If your main concern is keeping warm as you sleep, then why not consider purchasing a heated bunk warming pad? While this model by Electrowarmth costs more than your average heated travel blanket, this heated mattress pad has been specially designed to provide you with a long-lasting warmth during those cold winter nights.

Sized 36 by 60 inches, this pad is designed to fit your twin mattress. Like a regular 12V heated blanket, simply plug it into your 12V cigarette lighter socket to make your bed cozy in a few minutes. The heated pad will cycle on and off as needed to maintain your desired heat level as you sleep.

This heated pad is extremely easy to use, just turn the dial to adjust your heat level to anywhere between one and seven. On a high heat setting, its draw is estimated at around 6.2 amps. However, you could always use it at a lower setting to save power. Unlike electric blankets, this model is hand-washable for better hygiene.

All in all, we think this high-quality heated mattress pad is a great option for those who often wake up with a chill on winter camping trips.

Buyer’s Guide to Buying the Best 12v Heated Blanket

To help you to find the very best 12V heated blanket for your motorhome, we’ve listed some of the essential features that you’ll need to consider when making your purchase.

Price

There are plenty of moderately-priced 12V heated blankets out there. However, as there is such a large number of products, all at similar price points, it can make picking the best model for your motorhome even more difficult.

While cheaper versions are often synonymous with lower quality, we think there are plenty of good 12V heated travel blankets around the $30 mark. If you pay a little more, you can get extra features, such as a control panel, adjustable temperature and auto shut-off.

If you’d rather use a 12V heated mattress pad instead of a blanket, then you should expect to pay considerably more.

Power Supply

The beauty of 12V heated blankets is that you can plug them directly into your cigarette lighter socket on your dash and stay cozy warm when you’re out on the road. Once you’ve parked up, you may wish to use your blanket to heat up your bed before settling down to sleep.

Many heated blankets have a generous power cord length, but you could also add extra 12V cigarette lighter sockets inside your motorhome if required. You can also purchase connectors, adaptors and extensions, in order to run your blanket from deep discharge batteries that you recharge with your generator.

However you power your RV, be it shore side, solar or with a generator, bear in mind that your average 12V heated blanket will draw anywhere between 3-6 amps (36-72 Watts). If power is an issue, models with timers can be a better choice as their automatic cut off will prevent you from waking up to a flat battery in the morning.

Using an average 12V heated blanket all night will generally use up around 50-60% of one deep discharge battery. Models with automatic temperature control that cycle on and off will help to reduce this figure.

Auto Shut-off

Many heated blankets come with an auto shut-off function, that turns off your blanket once a set duration of time has passed.
Auto shut-off heated blankets allow you to fall asleep without worrying about running out of battery power overnight, making them ideal for small trailers with low power supplies. On the other hand, if you’re hooked up to shore power or have your generator running, you may want to run your blanket all night in the depth of winter. In this case, it’s best to opt for a heated blanket with a manual shut-off.

It’s important to bear in mind that your heated blanket should have a safety auto shut-off in case of overheating. Given the flammability of RV interiors and materials in general, once you’re warm in bed with your RV furnace fired up, you may prefer a timer model that shuts off automatically after a set amount of time.

Temperature Control & Heat Levels

Using a heated travel blanket with adjustable temperature and heat levels has many benefits.

Having the option to lower the temperature when you’re warming up can save you battery power. Likewise, having the possibility to crank up the heat levels is invaluable when getting into a freezing cold cab after a winter stroll, or to rapidly warm up your sleeping quarters.

Some models have basic low/high settings, while others allow you to set the actual temperature in degrees Fahrenheit. If you tend to feel the cold more than most, we recommend opting for a blanket with adjustable heat levels, so you can be sure that your blanket will reach a comfortable temperature for your needs.

Speed of Heating

If you tend to feel the cold, or if you are intending on using your 12V heated travel blankets as seat warmers, then you’ll want to pay attention to the amount of time it takes for your blanket to heat up.

While heating up your bedding shouldn’t be too much of an issue (simply leave it to warm while you get on with your evening tasks), if you’re freezing cold and relying on your blanket to warm you up, it’s best to get a fast heating model.

Warmth of Blanket when not Powered

It is also important to consider just how useful your heated blanket will be without power.

Unless you can run it non-stop, there are going to be times when you’ll use your blanket without power. Therefore, we recommend choosing one made from a good quality, insulating fabric for maximum heat retention.

Polyester fleece is a popular choice for heated electric travel blankets. You should also look at the thickness of the blanket and consider its overall weight to give you some idea of the warmth it will provide once the power has gone off.

Length of Power Cord

Whether you plan to use your blanket in the cab area, when sitting outside enjoying the view, or to keep you toasty overnight, the length of your power cord is important.

Depending upon the size and set up of your motorhome, you may have several different outlets, extensions or connectors to take into account. In general, a longer power cord is always more useful. Even more so if you are towing a travel trailer or fifth wheel and have cold passengers in the rear.

A cable of around 84-96 inches is standard and should give you plenty of flexibility.

Battery Life

Before purchasing a 12V heated blanket, take a few minutes to consider just how much power it will likely draw on a daily basis. Doing so will allow you to calculate if you need to make any existing changes should you have a very small set up.

If you feel the cold and expect to be using a heated travel blanket with a manual shut-off, then you should allow for a higher energy use than a model with a 45-minute automatic cut off. Leaving your heated blanket on all night plugged into your dash may completely run down your battery. So if you are using your dash cigarette lighter socket, always ensure that you unplug a manual shut off model before going to sleep.

Your RV deep discharge battery will be able to power your average 12V heated electric travel blanket for a night without running into over-discharge. Therefore, having a dedicated heated blanket battery is an option worth bearing in mind if you’re running a low-energy set up with a bare minimum of appliances.

Final Thoughts

Whether you’re looking for a 12V heated blanket with temperature control and an automatic timer shut off, like the Sojoy 12V Heated Blanket, or a basic manual shut-off model for all night warmth like the Camco Polar Fleece Heated Blanket, it’s clear there’s plenty of fantastic options to choose from.

So, take a few moments to consider your rig, your needs and your intended usage, then go back over our top 12V heated blanket reviews. You’re sure to find the perfect heated travel blanket to keep you cozy on your next winter RV adventure!.

About Karan Riley

I am the owner and main contributor to RV4Campers. I first got bit by the RVing bug when I joined a friend who was into Van Life for weekend getaways. It became apparent very quickly that this was a style of life I enjoyed and wanted more of, so it wasn't long before I had my own travel trailer. I didn't have a lot of money to throw around back then so I did lots of research into all the gear and gadgets. And this is how my RV passion exploded, I've now spent countless hours playing around with many different bits of kit and reading user manuals. And it's this wealth of knowledge I bring to RV4Campers.
