Kelvin jackets are known for featuring the latest heated clothing technology, and even more of that innovation can be found in our selection of accessories. Our Halsted Hand Warmer and Power Bank, X3 Battery and M1 Gold High Capacity Battery can be combined with your jacket to create hours of warm — and power for your portable devices — in all weather conditions. We don’t just make the best battery-heated jackets, we make the best heated clothing accessories, too.

How They Work

Our batteries and power banks work with your jacket to offer warmth and charging capabilities. Together, they’re equipped with the latest generation of heated clothing technology to keep you warm all day while also working as a power source for your mobile devices. You no longer need to worry about getting cold, and you don’t have to worry about your devices losing power, either.

To operate your Kelvin jacket battery make sure your power bank is charged, then plug your battery into the jacket using the cord found in the front left or inside left pocket (depending on which jacket you’re wearing). Press and hold the logo button located on the chest of the jacket and wait for the light to turn on. Once your jacket is on, you can cycle through the heating levels to provide the amount of warmth you need.

Your battery will work for a number of hours depending on which warmth setting you use. The X3 battery provides warmth for three hours on the high setting, five hours on the low setting and eight hours on the eco setting. The M1 Gold High Capacity Battery provides warmth for five hours on the high setting, six hours on the low setting and 12 hours on the eco setting. We encourage you to choose the heated clothing battery that suits the amount of warmth you need.

Warmth and Power

Kelvin heated jackets feature five core warming zones, with two of the zones located in the right and left pockets. Inside the hand-warming pocket is a lithium-ion battery with USB outputs for charging your portable device. This means you can charge your smartphone anywhere, anytime completely hassle-free. Kelvin Coats keep you cozy — and connected — in all conditions.

Browse our entire selection of heated clothing accessories to get the most out of your new Kelvin battery-heated jacket.
