OCOOPA 2 in 1 Magnetic Rechargeable Hand Warmers, UT2s Mini Electric Handwarmers 2 Pack, Split USB-C, Reusable Portable Pocket Heater, Raynauds, Golf, Christmas, Tech Gifts for Women Men

Excellent heat level with decent magnet strength. Incredibly easy to slip into my pockets, and super simple to turn on and use. The different heat settings are great! These are lightweight and a great color. USB-C charging was a must, and these function splendidly.

I bought one set and then ordered 2 more. I did realize the size when I first bought them but they are on the smaller side probably better for someone with smaller hands. But I'm still really loving these they don't last all day but around 4 hours on low was good enough. I just bought another set they are small enough to be pretty portable. They heat up pretty quick and get pretty warm on the highest setting. I really only use them on low. When I work outside these are awesome to have just enough so my hands aren't constantly freezing I have renauds? And these little hand warmers are really good. I've only had them for a little bit so I'm not sure how long they will last. But I got them on a deal for like $14 for a pair and I would probably buy them up to $20 any more than that I'd be looking for something that lasts longer

I love the magnetic design, you can use them together as one warmer or split them into two to warm both hands independently. The USB-C charging is fast and convenient, and the battery life easily lasts through long outings. They’re perfect for cold hands, Raynaud’s symptoms, outdoor activities or walking, or even just staying warm indoors. The smooth design fits comfortably in pockets or gloves without feeling bulky.

Works very well, nice and toasty! I wish they had a slightly bigger battery though! I really like this shape compared to others because they fit better in my hands!

Best little hand warmers a girl could ask for. three settings, easy to charge and lasts a decent amount of time, fits in my purse and comfortable to hold. People are always amused but I have Raynaud's syndrome so I carry them everywhere I go.

Love these! Hold the charge for a long time, heat up quick, perfect temp (not too hot). They've been a lifesaver on a few events now. Much better than the disposable ones.

I love these! I have really small hands, and I can wrap my fingers almost all the way around. They are about the diameter of a lipstick tube. They heat up really nicely and can get really hot. Because of the silicone texture, they don’t get too hot to handle though like other brands I have that have a metallic outer shell.

These hand warmers are great in every way except the length of time they stay warm which is why I’m giving them 3 stars. Their overall design is good as they are comfortable to grip and hold. They seem well made and solid. They offer USB C charging and include a dual charger. They come packaged very well and include lanyards for easier holding. There are 3 different levels of heat and both units get hot very fast- within seconds. Now the bad part: I used these for two separate occasions while outdoors for an extended period of time in 30 degree weather. The first time, at maximum heat they lasted about 3 hours until both units fully died. The second use they lasted about 2 hours until both units fully died. Understandably at heat level 1 or 2 I’m sure they last longer but at heat level 3 is when you really feel the warmth for cold outdoor days. Each separate unit is 2500mah which is fairly low compared to other warmers out there which offer more value at higher charge holding. Overall these warmers are fine if you plan to use them for short durations but if you work outside or plan to use them for long periods of time (3 hours or more), they just don’t hit the mark.
