Best 12V Kettle For Car

Now let’s take a look at the best 12 volt car kettles on the market one by one.

FDIT Portable Car / Truck Kettle (Versatile)

Fdit Portable Car Electric Kettle Road Trip Travel Cigarette Lighter DC12V/24V Heated Water Tea Coffee Kettle Auto Shut Off (1000ml (Kettle) (12V)CHECK CURRENT PRICE

The Fdit Car Kettle is an extremely light and portable travel water heater kettle for your car, which can heat up to 1000 ml of liquid in 25 minutes. This kettle works with both 12v and 24v, so it is a great choice if you are looking for the best trucker’s kettle.

This 12 volt hot water kettle can be used in cars, trucks, buses, RVs, and other vehicles. Make your journey more enjoyable by taking advantage of its versatile dual-voltage hot pot.

The kettle powers off automatically when the liquid inside reaches boiling temperature. The kettle’s safety protection feature switches it off and prevents it from overheating and melting if all water has evaporated and the kettle is empty.

This water heater for cars is powered by a 12-volt cigarette lighter socket, like all kettles of this type.

The Fdit kettle is made from non-toxic material food-grade plastic. These materials ensure durability and health safety.

The 12V car water boiler is convenient for those who often need to go on long journeys. This appliance can easily be used for up to 3-4 years since it has been manufactured from quality materials.


  • Functions – car water heater
  • Voltage – dual voltage 12V and 24V
  • Cup capacity – 1000 ml
  • Power – 150W @ 12V / 250W @ 24V
  • Heating time – 25 minutes
  • Maximum water temperature – 248.0℉ / 100 C


  • An efficient charging base ensures the safety and sufficiency of heating
  • Lightweight build
  • Dual voltage 12 and 24 volt compatible

Spardar Car Kettle and Insulated Cup

Spardar Car Kettle 12V Portable Car Water Boiler Stainless Steel, Quick Boiling, Auto Shut-Off, Leak Proof and Boil-Dry Protection,CHECK CURRENT PRICE

The Spardar Car Cigarette Lighter DC12V Electric Kettle has a very special design. This model promotes efficiency and comfort in multiple ways. The mini electric kettle weighs a bit over 1 pound with a dimension of 10 x 3 x 3 inches.

The Spardar Car Cigarette Lighter charger kettle is available in multiple colors: ash deep gray, azure, rose red, blue, dark black,  orange, and grey. I have found the grey one to be more adaptable to the car interior.

The heating insulation cup has been built with dual-layer stainless steel. It takes less than 20 minutes to heat 320ml of water in default 120W mode.

The digital temperature display is a techy addition to the kettle if you ask me. The thick film heating technology accelerates the rate of heating. Did I mention that the heating temperature can be customized?

The water heater has a temperature maintenance mode that keeps the water temperature within 5 degrees of your target temperature.

Moreover, the double-layer vacuum body lessens the cooling rate inside. For safety purposes, this kettle comes in food-grade silicon rubber. The rubber prevents the kettle from slipping off the hand due to high friction.

The capacity of the cup is 348ml, which is great if 3-4 people are using it at a time. But, the cap of the 12-volt kettle has been found to be incapable of venting steam.

As its name says, the kettle uses 12V DC. You can choose 80W or 120W mode depending on your car wiring. The default power setting is 120W, but if you are not in a hurry, switching to 80W will let you save a bit of power.

This portable 12 volt water kettle is suitable for preparing tea or coffee, making instant noodles, and heating milk. It is a convenient gadget for school car trips and camping trips.

Road Pro 5027S

RoadPro 12-Volt 20oz. Smart Car Pot - Black - 5027SCHECK CURRENT PRICE

The Road Pro 5027S is a 12 volt kettle you can use to boil water in the car during your journey. The 12V tea kettle for car is slim and features a space-saving design.

However, the quantity of liquid the electric water pot can hold (20 ounces) might not be sufficient for multiple campers.

The 12 volt car water heater has to be plugged directly into the socket to get the power on. This is a feature found in all other travel water boilers (like FDIT portable car 12V water boiler and Uniox portable kettle).

When the water boiler reaches the desired temperature, it turns off automatically. The Road Pro travel kettle takes up to 45 minutes to boil water. Though the design is not fancy, it is useful. But, the not-so-tight lid may prove to be an annoying factor for many users.

I have been in much of a dilemma on whether to give a positive or a negative review of this model. Although it is not the best water boiler out there, it is able to serve the main purpose behind buying it for a reasonable amount of money.

To conclude, you will get what you are paying for. Do not expect this kettle to serve for years, and you will not be disappointed.

  • The lid is not air-tight, so the liquid inside does not remain hot for a long time
  • It takes a long time to boil the water
  • Bad design of the spout

12V Car Kettle Buying Guide

The features people expect from a portable traveling 12V camping kettle are flexibility, light-weight, lower power consumption, tight lid, quantity, safety, durability, and wide using capability.

From my research on these appliances, I can tell you what to expect and what not to from these products.

Kettle vs. Cup

The Uniox kettle is made from stainless steel and food-grade plastic. The insulation formulated cup prevents the water from getting cold easily. It keeps water hot. The kettle can be used to enjoy the prepared food without having to serve it on any other plate. It is small in size and very convenient to use for any kind of trips and journeys.

The FDIT portable 12V kettle and the Roadpro 5072S come in kettle style. The kettles are convenient to use, though they are more space-consuming and heavy in weight. However, the kettles are cheaper than the cup style car water boilers. The food-grade elements used in these kettles are also of high pedigree.

Dual voltage

Some travel water boilers perform on dual voltages. In many cases, it is seen that car water heaters need a variable of voltages to work on. The power supply of vehicles varies from one vehicle type to another. The FDIX car travel kettle works with both 12-volt passenger car and 24-volt truck electrical systems. This kettle can be used in both cars and trucks.

If one is looking to buy a portable small electric kettle you can use in a car and truck, only then, the dual voltage device is feasible. It is to be noted that the option of 12 volt car tea kettle is much more applicable for car users.


The capacity of the 12V water kettle depends on the use of the customers. Generally, the demand is for medium capacity kettles of 300-500 ml. The kettle with more capacity consumes more space and is also of more weight. Customers usually prefer light-weight and portable appliances.

The Uniox car hot pot is light in weight and consumes less space. If the customer size is of 5 or 6 members then they do need a high capacity kettle to prepare more food at the same time. On the other hand, if the customer size is of 2 or 3 members then a medium or small capacity kettle is enough and convenient for them. The low capacity kettle needs less time to boil the liquid inside.


The best 12v car water boiler models mentioned in this review come from Uniox, FDIT, and Road Pro. What to do to maintain the unit properly and what not to do to prevent destruction are discussed below.


  • Always unplug the base first, then let the kettle cool down and remove the remaining liquid from the kettle; then, get it clean to avoid any kind of electric shocks.
  • Soap water should be used to clean the inner part of the travel kettle
  • The electric 12 volt kettle for car should not be immersed in water completely
  • A sponge or damp cloth should be used to clean the outer area of the kettle
  • To avoid accidents, the kettle should be operated on a flat surface
  • Keep leather items away to avoid steam damage
  • Children should be kept away from the kettle
  • When the kettle is heating up but not boiling, you should use lime to descale mineral deposits.
  • If you have a propane stove in your RV, consider making a stop and using the stove to boil the water. Get a thinner aluminum pot with tight-fitting lid, and have boiling water within 2 minutes.
  • If you plan to use your kettle regularly, you should upgrade the standard cigarette lighter receptacle to a quality marine one, like Blue Seas, and upgrade the wiring to it from the battery with at least 12awg, preferable 10awg.


  • We should not use abrasive soaps or cleansers
  • Don’t open the lid of the kettle without powering off the kettle
  • Don’t keep the mouth of the kettle open for a long time
  • Don’t let any liquid stay inside the kettle for a long time
  • Do not use battery power to heat water. Keep the engine or generator running.

Frequently Asked Questions

I heard about the battery-operated water kettle. Is it a thing?

Battery powered water kettles are a new thing. While I used to believe that it is very inefficient to power a hot water maker from the battery, there are several brands offering such kettles, for example, Makita XTK01Z. I am looking into it.
