The OCOOPA UT5 Nano rechargeable hand warmers are ultra-slim, two compact pocket heaters that deliver up to 7 hours of adjustable heat in a stylish, durable design.

Designed for cold-weather commuters, outdoor enthusiasts, and anyone who needs fast, portable warmth, the UT5 Nano pair combines a lightweight profile with user-friendly controls and a textured finish. These pocket-sized warmers charge via USB and offer three heat settings so you can fine-tune the temperature for comfort during daily errands, sports, or winter travel.

How quickly do the UT5 Nano hand warmers start heating?

The single-button control gets the unit heating within seconds, so you don’t wait long to feel warmth. Choose from three levels to ramp heat up or down depending on conditions.

• One-button activation for immediate warmth
• Heat begins in about 2 seconds after turning on
• Three adjustable temperature settings for personalized comfort

How long will a single charge keep my hands warm?

Each UT5 Nano contains a UL-certified rechargeable battery designed to deliver extended, steady heat through the day. Battery life depends on the chosen heat level and ambient temperature.

• Up to 7 hours of runtime on lower settings
• Shorter runtime at the highest heat level for more intense warmth
• USB rechargeability makes topping up easy between uses

Will these fit in pockets, gloves, or small bags?

The UT5 Nano was engineered to be ultra-slim and lightweight so it slips conveniently into jeans or glove linings without bulk. The compact dimensions make them a discreet option for commuting and outdoor activities.

• Slim profile fits most pockets and glove compartments
• Lightweight—easier to carry than most smartphones
• Pair of two provides heat for both hands or a backup device

What makes the design and finish stand out?

OCOOPA collaborated with Artist in bloom to add an embossed texture and a premium finish that resists scratches and daily wear. The result is a functional warmer that looks and feels refined enough to gift.
