Why Get a USB Heater?
Here are some of the reasons why you should get a USB heater:
The Portability and Convenience
USB heaters provide warmth and comfort in a remarkably compact form factor. Unlike bulky space heaters, these mini heaters easily fit in your pocket or bag to provide heat on the go. Their small size and USB power source mean you can use them anywhere – at your desk, in your car, while traveling, or outdoors.
Energy Efficient Personal Heating
The low-power draw of USB heaters through your computer or battery pack makes them incredibly energy efficient. For just a few watts of electricity, you can generate direct heat to keep your hands toasty or take the chill out of a small space.
Precise Temperature Control
With features like adjustable temperature settings and auto shut-off timers on some models, it’s easy to dial in the perfect amount of warmth right where you need it. USB heaters provide personalized climate control for any situation.
Can a USB Powered Heater Be Dangerous?
Generally, a USB-powered heater is completely safe to use. USB heaters use low-power batteries that typically require 5-volt chargers.
That said, these are electric heating devices that may overheat and start a fire. And so, you shouldn’t leave them turned on for a long time. Also, make sure to turn off the power when you’re not using them.
While these devices draw power through a USB port, we don’t recommend plugging them into your computer, except for the heated computer mouse pad. These devices can get too hot and may damage your PC when used for longer periods. Instead, use a proper power supply such as a dedicated charging brick.
It’s also a good practice to allow the heating element to cool down properly before using the device again. This is crucial especially if you’re using a USB space heater or an electric golf cart heater. Such devices draw more electric power and generate more heat.
What Are The Best Portable USB Heater/Heating Options?
Best USB Heater for Camping
OCOOPA Rechargeable Hand Warmer
OCOOPA hand warmers are incredibly light for something so powerful. With their suede-like surface, you won’t believe just how soft and comfy they are on your hands. The curved edge allows even the smallest of hands to wrap their fingers around the device while taking advantage of the double-sided heating feature.
But what makes this USB portable heater stand out from competitors is the lack of metal parts. Metal components can make the unit cold to the touch before heating up.
This USB mini space heater comes with 3 heat settings. The highest setting can be uncomfortably hot, though. So, you’re going to need some sort of barrier between your hands and the device, such as a glove or something.
At the highest setting, expect the OCOOPA rechargeable hand warmer to run for about 4 hours non-stop. Running time could be longer if it weren’t for the 5200mAh battery. There are several color options for a more personal touch, and its size and shape make it perfect for taking camping or anywhere.
Perfect for Office Desk
ValleyX Heated Computer Mouse Pad
The ValleyX heated mouse pad can be an excellent addition to your arsenal of office desktop peripherals. It does a great job of keeping your hand toasty warm while gaming or working.
This USB-powered heater for the hand can heat up quickly once plugged in a USB port of your computer. It comes with a switch that allows you to adjust to your desired temperature. Plus, you don’t have to worry about not turning it off when you’re not using it since it is equipped with a programmable shut-off timer.
While the ValleyX USB-heated mouse pad comes with a fan, it does not evenly distribute warm air throughout your hand. The wrist rest is comfortable but it needs to be a bit higher. Further, it would have been a lot cozier if the breathable fuzzy warm material was on the inside.
Best for Your Feet
Lomitech Electric Heated Warmer
With this USB-powered heater from Lomitech, you get the best of both worlds — a warmer and massager for your tired and freezing feet. There are 3 modes of operation or intensity — heat therapy, vibration, and a combination of both. Each mode comes with a distinct colored flashing light, indicating which mode is currently operating.
The outside and inside materials of this electric heated foot warmer are made from an ultra-plush micro mink fabric. The thick plush cover helps prevent heat loss while the inside material provides comfort for your feet.
The Lomitech heated warmer is ideal for traveling as it is lightweight and surprisingly portable. It also has a storage pocket for the USB power cord.
Good for On the Go
Sunbeam USB Heating Pad
The Sunbeam heating pad is an affordable device when you need on-the-go heat therapy for a specific body part. The fully flexible adjustable strap allows you to wrap the heating pad around any body part with ease.
This USB-powered personal heater works great for those heat therapy sessions on long car trips. You’ll appreciate the device’s versatility, from your car to walking around in stores, and being able to plug in as you arrive at any destination.
This heating pad does not come with a battery so it needs to be plugged into a USB power source to make it work. The pad is made from a lightweight and ultra-soft micro mink fabric material.
However, the strap of this Sunbeam USB heating pad is designed so it can be easily removed, not to securely hold the pad over time.
Best for Car
Prosmart Heated Vest with USB Battery
The Prosmart heated vest may look like a traditional vest for winter but it does an excellent job of keeping you snugly warm all day.
Made from high-quality fleece material, the vest can keep you warm all by itself even without turning the power on. You will love the sewing, style, and overall construction of this USB-powered heater/wearable option from Prosmart.
A dedicated 10000mah battery powers the carbon fiber heating element for 7 hours or so. You can use any aftermarket battery as a secondary power source as long as it is 5V, 3 Amps, and input at 5V, 2 Amps.
The Prosmart heated vest with a USB battery is a combination of high-quality material, excellent construction, and good customer service. Still, the performance of the 2 heating elements inside the vest can be a bit of a disappointment.
Finding the Perfect USB Heater: Key Buying Considerations
Purchasing a USB heater involves more than just picking the first option you see. Taking the time to understand key features and weigh your priorities will ensure you select the best USB heater for your needs. Below are the most important factors to consider:
Power Capacity
Pay attention to the power output or wattage of USB heater models. Higher wattage equates to more heating power. Consider your intended use – if you want a compact but mighty heater for your desk, choose a more powerful model. For subtle warmth, a lower wattage may suffice.
Portability
The dimensions and weight of a USB heater impact its portability. More compact, lightweight designs are great for tossing in your bag and using on the go. Bulkier models may be better suited for stationary use in one main location.
Adjustability
Having options for temperature and fan speed settings allows you to customize the heating experience to your preference.
Noise Level
If you prefer quiet operation, seek out USB heaters specially designed for silent running. Check decibel levels in product specs.
Battery Life
Lithium-ion batteries power most USB heaters. Prioritize units with higher mAH batteries for longer-lasting performance per charge.
Warranty
Opt for at least a 1-year warranty. This provides recourse if the product is defective. Stick to reputable brands known for honoring warranties.
Extras
From reverse charging to flashlights, today’s USB heaters offer bonus features. Decide which extras would enhance convenience and value for you.
The Takeaway
USB heaters provide personalized, precision warming in a remarkably compact form. Their portability, USB power source, and energy efficiency make them ideal for heating on the go.
Evaluate your needs and compare top models to choose the best USB heater. Opt for sufficient power capacity, battery life, adjustability, and features like auto shut-off. Consider warranty and brand reputation as well.
Stay cozy all winter long with your new USB heater! Plug it in at home, in your car, at the office – anywhere you need instant warmth. Don’t suffer the cold; take control with convenient USB heating.
