OCOOPA Magnetic Rechargeable Hand Warmers 2 Pack - IP45 Water Resistant, UL Certified, Portable Electric Hand Warmer with 9-Hour Battery Life - Perfect for Winter Sports, Camping, Hiking & Raynaud's Syndrome Relief - Great Tech Gift for Men & Women

The UT4 Urban is nice and compact with a nice, stylish design features. A curve grips nicely in the palm. The blue colorway looks really sharp. Nicely sized overall for fitting in a glove in your hand and nice and lightweight weighing in at 83 g each.Packaging comes with two individual heaters. Two nylon lanyards a Y-cable from USBA to two USBC connections, a carrying pouch along with instructions. Heaters snap together nicely with a magnet for easy storage in your pocket or the pouch. I like the Y cable design as its removes one more cable to carry around and makes charging a bit easier too.Performance was good with rapid heating from room temperature to low point of 36C. Medium setpoint of 42C and a high of 48C. All very good usable temperatures without being too warm or uncomfortable in the hand. I tend to keep it on low setting as I feel like that is the easiest to hold in the hand and offers the most warmth and length of usage. Units also cycle on and off to help with battery life and don't maintain the high temperature for the entire time. A good compromise for me and helps with comfort.Overall, I really like these hand warmers. They're nice and compact and fit into mittens or pockets with ease. Offer nice amount of warmth for the size and run time and look pretty sharp. Compared to the other Ocoopa hand warmers I have tried these strike the best balance of size and performance. When paired with mittens or gloves these are probably the most versatile in the lineup.
