    Warm hands wherever you go

    The EnergyFlux Ellipse features an easy-to-grip shape and size with plenty of battery power to keep your hands warm and toasty for hours. There's no better companion on a cold day or whenever you're feeling chilly! With two temperature modes set to 42°C and 48°C, wrap-around heat and quick warm up time, EnergyFlux Ellipse is a snap to use and will make your hands warm and comfy in a flash.

    Waste less

    The EnergyFlux Ellipse is rechargeable, so it’s ready to go again after a few hours of charging. No more throwing out hand warmer pouches that just end up as landfill and no fussing with lighter fluid and trying to light catalytic warmers with cold fingers.

    Easy to use

    One button controls it all. Press and hold the button until the red LED starts flashing—it’s on and heating! Once on, a quick press of the button will switch between high and low heat. The red LED will flash to indicate the Ellipse is warming—slow for low heat, and fast for high heat. Blue LEDs will let you know how much power is left. Just press and hold the button again to turn the warmer off.

    Charging phones and other USB-powered devices is even easier. Just use the USB cable that came with your device or the Ellipse (if your device uses Micro USB) to connect to the Ellipse’s USB port. As soon as you plug in, the Ellipse will come alive and start charging your phone, etc.


    - The EnergyFlux does its best to maintain the temperature it is set at, and therefore needs to be charged more often in colder temperatures.

    - Modern battery products must be charged every month or two when not in use.
