Why do we need rechargeable hand warmers instead of disposable hand warmers?
Rechargeable hand warmers are a climate friendly and economical choice. They can be used repeatedly, create less waste, and are stronger and more durable than disposable ones, making them perfect for outdoor activities and cold weather.
Will these hand warmers be easy and safe to put into gloves?
UT3 Lite hand warmer is ultra-thin and lightweight, with a thickness of only 1.85cm. It is easy to put into gloves or pockets and is UL safety certified for safety.Safety Tip: Avoid prolonged direct contact with skin to prevent low-temperature burns.
How are the heating settings and how long will they stay charged?

- Low: 107°F for 8 hours
- Medium: 116°F for 6 hours
