This innovative bottle features a detachable cooling fan with three-speed settings to provide instant relief from heat. The integrated power bank lets you charge your phone and small devices without carrying additional gear. With these smart features, the M440 offers both refreshment and convenience in a single, portable design.
Double-wall vacuum insulation keeps beverages hot or cold for up to 24 hours. The wide mouth design allows for easy cleaning and fits standard ice cubes, making it ideal for both hot coffee or icy drinks during intense workouts.
The bottle includes two leak-proof, interchangeable lids—a straw lid for daily hydration and a fan/power bank lid for workouts or travel. It also comes with a cleaning brush and spare parts, making maintenance effortless.
With a generous 40oz capacity, the M440 reduces the need for constant refills. Its slim profile fits most cup holders and bike racks, and it includes a USB-C charging cable and user manual for immediate use right out of the box
