OCOOPA UT4 Urban Magnetic Hand Warmers Rechargeable 2 Pack, IP45 Waterproof, Up to 9Hrs, 3000mAhX2, UL Certified, Electric Hand Heater for Outdoors, Hiking, Hunting Gear, Tech Gifts for Men Women

I bought these for my wife to warm up cold hands on the ski slopes. I suffer badly from cold hands so we both used them in the mountains on cold days. They are very, very effective at taking off the chill and getting properly comfortable again. They warm up REALLY quickly... in fact the hottest setting is too hot to touch as a starter. It's possible you may need to ramp up to this when the battery gets low but we havent reached that point yet. Our experience is that they run for atleast 5 hours on a mix of low and medium setting. The only downside is the size. They are a bit big for fitting inside ski gloves but squeeze into a medium mitt without being uncomfortable. We were so pleased with them that I bought a smaller version to use in my walking gloves. Well worth the spend!

Bought these to take to a job site in the middle of winter with temperatures ~ -10. These hand warmers were an absolute godsend. On low, they would near enough last me a full work day and provided enough heat to keep my fingers from getting numb and would charge up over night with no issues. The design is sleak and the curved profile is comfortable to hold both when theyre together and apart. The magnets are decently strong and helps keep them together when storing and charging.

Nice size and shape which fit neatly into your hands. Initial heat is excellent but diminishes during a round of golf to lukewarm. Anyhow reasonably happy with overall purchase.

This is a great product for someone with arthritis as it keeps the hands warm all day. It lies next to my computer mouse on the desk and when my hands start to get cold, I just place my hand over it. The battery lasts a really long time and with 3 settings you can choose how warm you want it. It is very easy to use, press a button and within a minute you have a nice warm handwarmer. I bought more of these as Christmas gifts and would recommend them.

Bought for teenage son. He thinks they are great !! He has to out at 6am to catch a bus that takes over an hour to destination so these help so much on cold winter mornings.

Got them for my dad as he has circulation problems and always has cold hands. He doesn’t leave the house without them now.

I've had these for about 2 years and they still last a long time even when using them for a good amount of the day. Comes with a wire which charges both at the same time and they get really hot. Life saver for the winter.

Really good hard warmers keeps your fingers toasty . Size is spot on

Calentadores de mano excelentes y en los climas más extremos

Amis instrumentistes qui devez jouer dans des ambiances froides (églises, plein air, estrades, etc.) voilà Voici une chaufferette à la fois efficace (je ne dépasse jamais le niveau I ) robuste (elles sont étanches) et fiable (plus de 8h de chauffe en continu). Elles sont livrées par deux, avec un petit sac de rangement et un câble en Y de charge. Elles sont aimantées afin de tenir collées l'une à l'autre. Elles ne chauffent que d'une face, c'est le prix à payer pour un encombrement et un poids minimum. C'est assez petit pour tenir dans la poche sans faire de bosse, et assez grand pour avoir une surface de chauffe suffisante. C'est livré sous blister dans une jolie boîte cartonnée solide. Vous l'aurez deviné, j'en suis ravi ! Cela à l'air solide, mais avec les accus et l'électronique, on est jamais certain de la durée de vie. Espérons ... En tout cas, je recommande chaudement (ah ah ah ! je sais, elle est navrante.)

I got the blue coloured ones, I bought these as a Christmas gift for my bf. He really like them they warm up very quickly! The value for the cost I feel is good, definitely worth the price. These come with wrist straps and a carrying case for ease of transport. These are great because they are not too big, you could put them in your pockets or in your gloves with your hands depending on how stretchy your gloves are. The functionality is great, they have three heat levels and get very warm! They aren’t very bulky at all. I like that they are also magnetic so you can also use them as a single double sided warmer if only one hand is cold. I love the charge cord, double ended c charger so you can charge both of these at the same time. The battery life is yet to be determined, he hasn’t used them enough to discuss that. I will assume it is good, however will update my review if I change my opinion once he’s used them a bit more. I really like the design of these warmers.

Esta marca me tiene encantada, esta es mi 2a compra y calientan bastante. Me gusta que sean como más de uso rudo y no les pase nada.
