Description:
This compact rechargeable hand warmer combines a split magnetic design with double-sided heating to keep fingers and palms warm during cold days. It works as two separate pocket heaters or as a single unit for broader coverage, offering rapid warmth and variable temperature control for outdoor activities or daily commutes.
Key Points
The magnetic attraction lets the two halves attach quickly, turning them into a single warmer for more even heating across both hands. The unit heats up in about two seconds according to the manufacturer, which is useful when you need fast comfort outdoors. It includes 3 adjustable heat levels so you can choose a gentle warm setting or a higher temperature for chillier conditions. 🔥
Charging is through a USB-C port and the internal lithium battery reaches full charge in roughly 3 to 4 hours. For longer outings, the hand warmer is claimed to provide continuous heat for up to 24 hours at lower settings, although actual duration may vary with the selected temperature and usage patterns. The device also features simple button operation and an LED indicator to show power status and heat level. âš¡
A note on materials and safety: the outer shell combines aluminium and ABS plastic, and the product includes built-in protections against overcurrent, short circuit and overload according to the manufacturer. Consider that higher heat settings will reduce run time and that battery life will decrease slowly over many charge cycles.

Usage Recommendations
For quick relief on cold commutes, start on the mid heat level for a balance between warmth and battery life. When using outdoors in very low temperatures, attach both halves together to use the double-sided heating and improve coverage for hands and fingertips. The unit can also be placed in pockets to warm clothing or used near the stomach or lower back for temporary heat comfort. 🎒
Operate by holding the button for three seconds to switch on or off. Press once to step through the heat levels and double-click to display the battery indicator. Keep the device dry and avoid extended exposure to very wet conditions, as it is not specified as waterproof.
