9. ALEKO CARKT12V Portable Travel Hot Pot

Portable Travel Hot Pot
Ok, we’ve seen high-tech designs boasting their digital displays and their sleek portability sizes.

But let me digress for a bit, and I don’t mean regress, just a simple step back to see what the classics are and prove that the functionality can never go out of style.

The Aleko Carkt12V Portable Travel Hot Pot may sound fancy for its extended name, but it’s merely the old electric kettle that you can plug in your car.

You’ve read it right; it’s an electric kettle instead of a 120V or 220V plug, you have the standard 12V DC plug for your car.

The innovation might be as simple as that, but people seeing this can still boggle them up.

Yes, the RoadPro Beverage Heater is a simple device that doesn’t need all the intricacies of all the smart mugs out there.

A straightforward heating mechanism that works as soon as it is plugged on your 12V car socket.

All you need is a cup, mug, or any beverage container that is safe for hot liquids, the actual beverage you need to heat.

And, of course, a car so you can plug the device and voila it heats your drink in a few minutes.

But isn’t it dangerous you ask, I daresay as long as you don’t intentionally play it with your fingers while it is heating, it’s completely safe.

It has a safety clip, so it doesn’t touch the cup or mug while it is heating.

Although it offers simplicity and versatility with your choice of mugs, you have to be mindful of using it since it’s not as smart as the rest of the nominations.

If you’re as clumsy as a kid, then go with the ones that have an extra safety feature, in this case, choose the ones with a liquid container that can heat things inside it.

But if you are in control of things and are attentive to potential mishaps, then a very simple water heater with all its versatility will be perfect for you.

  • You choose your mug or cup
