A soft silicone-wrapped single warmer that CNN Underscored found more comfortable to hold than its top pick, with heat from all sides and USB-C charging. It heated more slowly and ran out sooner than the Ocoopa UT2, you need two to warm both hands, and 17% of its few Amazon ratings are 1 star.
Top complaints
- Slower and shorter than the Ocoopa UT2
CNN kept the Ocoopa UT2 as its top pick because the UT2 heated up faster and lasted longer on a single charge.
Source: CNN Underscored - You have to buy two
It's sold singly, so warming both hands means buying a second unit or a bundle, which makes it more expensive than a pair (CNN).

What experts say
- CNN Underscored: Considered but not a pick (2026 guide): a better fit in the hand than the Ocoopa UT2, but slower to heat, shorter-lasting and single-hand only. The smaller PowerPaw 501 (just over 3 oz) is a cheaper sibling.
