USB Heater: 5 USB Powered Heaters Actually Worth Buying

If you’re looking for a way to keep your toes warm this winter, meet the USB powered heater. This nifty little device plugs into any of your computers’ USB ports and provides instant heat. 

It’s perfect for those who spend most of their time on the computer – whether it be at work or school. USB portable heaters come in many shapes and forms – as a hand warmer, heating pads, or a warmer for your coffee mug.

In this article we will talk all about USB powered heaters. 

How do they work? Are USB heaters safe? What are some of the best USB heaters on the market today?

Let’s start exploring!

What is a USB powered heater?

They are portable heaters with a USB plug that can be plugged into any powered USB port (ex: laptop, wall charger). While they normally don’t serve as space heaters, you can purchase USB powered hand warmers, or other types of clothing, USB heating pads, or USB coffee mug heaters. 

They’re usually small and compact enough to fit in a coat pocket, backpack, briefcase, or purse. Some models also run on batteries. 

You can also find USB (rechargable) heaters for camping, USB personal heaters, as well as USB space heaters.

USB powered heaters are electric, relying on a resistance wire to warm up and generate heat. The higher-powered ones may only take a couple minutes to warm up, but the less powerful ones can take around 10-15 minutes before the desired temperature is reached.

These USB heaters are great to provide additional heat in the form of heated clothing, hand warmers, or keeping your hot drink hot.

However, you should be careful when handling these heaters as they can get very hot. Leaving them on for extended amounts of time can cause overheating, burning the user, and damaging the USB port the device is plugged into.

Luckily, many USB heaters have an adjustable thermostat built in, allowing you to set the desired temperature and stop once reached. You can also attach timers to some models so they shut off after a certain amount of time, reducing the risk of overheating.

Overall, USB heaters are a cheap and convenient way to stay warm especially during cold spells and are great for travelling as they don’t take up too much space.

Are USB heaters safe?

USB heaters generally are safe. 

However, since most USB heaters are electric, it’s important to remember that they can get very hot. Leaving them on for long periods without supervision could cause fires if they are not monitored. 

For this reason, it’s important to allow time for the heater to cool down before using again or packing away.

You should also be careful when plugging a USB heater into a USB port on a computer or laptop, as this could cause damage to the device. To avoid overheating and possible permanent damage, you need to make sure that if using a laptop, you only ever use it from the battery and not from mains power.
