Petzl Rechargeable Dual Palm Handwarmer

Jump to: Our Verdict / Features / Specifications

The Lifesystems Rechargeable Dual Palm Handwarmer offers a simple, versatile way to keep hands warm on chilly trips.

Lifesystems says: 

These Dual Palm Rechargeable Hand Warmers have a split magnetic design which allows you to warm both hands without having to have them next to each other. With 3 heat settings, you are able to easily adjust the hand warmers to the ideal temperature for you and the conditions you are in. The USB-C cable allows you to charge your mobile from the hand warmers, meaning you can stay connected while out adventuring. At the touch of a button, the rapid start will deliver heat for up to 9 hours. The hand warmers can easily be recharged by using the mains or USB.

Our Verdict

The pair weighs 225 g, and the split magnetic design means I can warm both hands at once, whether holding them together or separately in pockets. I appreciate the three heat settings, which range from 40°C to 50°C—plenty of warmth for cold mornings. They heat up fast, reaching temperature in about 10 seconds, and I’ve found the battery life holds up well, giving around 6–9 hours, depending on the setting.

Each unit doubles as a power bank, with USB-C charging and a decent 5000mAh capacity per side, which could be handy for topping up a phone. I like that they nest together magnetically, making them easier to carry and less likely to get lost.
