12V Kettle for a Car Buying Considerations

Volume or Capacity

Every car kettle is different, and many will have different volumes or capacities that can be contained within the kettle. Most will come in volumes of 750ml, but you can find capacities from below 500ml or above 1000ml. What size you choose is dependent entirely on your preferences and whatever fits your needs best. Larger capacities tend to be more convenient, but you may not use the full kettle yourself, so don’t be afraid to get a smaller kettle if that’s what you’re more comfortable with.

Temperature Control

The best car kettle needs to provide an ergonomic way to regulate the temperature of your water or other liquids. Kettles that offer controls of at least 10 to 90 degrees are great for controlling the temperature of your drink, and ones with LCD displays are incredibly helpful. The LCD display will make it very easy to read and control the temperature, so you don’t have to worry about your drink not being hot enough or, conversely, being too hot to handle.

Materials and Construction

As with most electronic devices you purchase, you likely want your car kettle to last for years to come, and also want it to be safe to use. After all, the best type of 12-volt car kettle is one that will serve its purpose for years to come. As a result, the best car kettles are made with 304-stainless steel material primarily. This is food-grade stainless steel that will not rust or deteriorate with use. You may also find ceramic kettles and kettles made from food-safe plastics.

Aside from the materials of the kettle itself, you should be looking at the handle of the kettle. You want the handle to feel comfortable in your grip. The handle should be ergonomic and both safe and easy to carry. Additionally, you should look for kettles with an anti-slip base.

The Final Word

If you’re considering a portable kettle for your next camping trip or car journey, be sure to choose one that's proven to work, as some of the cheaper models out there simply take forever to heat the water up, or in some cases, don't boil the water at all. To ensure that you’re buying into a model that won't let you down on your next hour of need when you fancy a cuppa on the go, select one of our best 12 volt car kettle selections further up.
