I love these hand warmers! I bought these just in time to use at my kids outdoor sports games this Fall. The charge lasts for at least 4 hours (I didn't time it but it made it through 2 youth football games and then some) The dual charging cord is a major plus, I use them both so charging at the same time is a big time saver and having the USB end makes it easy to charge in my vehicle if I need to. These are good quality and they work great. These warmers fit perfect in my palms. The heat range is just right, the lower setting feels like the disposable hot hands, I love that these can be much warmer. The box they come in is a nice touch also. I will be ordering more from Ocoopa, everyone would like a pair of their own now. Read more

I bought these as stocking stuffers but wanted to check the quality. I am pleasantly surprised. They get nice and hot, and last a long time. I used them for prob 5 hours and they were still going. The hot setting was almost too hot at times, depending how cold I was. So I ended up switching between the first and third setting. They magnetize together and come with a carrying strap for both sides so you dont lose them. I did have to open one up and switch the magnet because they were magnetizing backwards end to end but it was a simple fix and they work great. I bought more to engrave and give as employee gifts because I was such a fan! They engraved beautifully. Read more

Can charge both at same time even in the car via USB port. Three heat settings can go in your gloves or pocket , hot enough to warm your hands. Read more

Die akkubetriebenen Taschenwärmer haben mich wirklich überzeugt. Sie heizen sich schnell auf, bieten mehrere Wärmestufen und bleiben über Stunden angenehm warm. Besonders praktisch ist die wiederaufladbare Funktion, wodurch Einwegwärmer überflüssig werden. Das kompakte, robuste Design passt in jede Jackentasche und macht sie zum idealen Begleiter bei Winterspaziergängen, Outdoor-Aktivitäten oder kalten Arbeitstagen. Insgesamt ein zuverlässiges, komfortables Produkt, das ich absolut weiterempfehlen kann. Read more

menudo descubrimiento para calentar las manos durante un marcha larga por el campo!! estuve probando unos 10 años para ver cuál era la duración real tienen 3 intensidades y en principio me pareció que tenía que usar la alta pero la realidad es que cuando lo metes en el guante con la baja es suficiente porque las otras llegan a quemar un poco por la diferencia de temperatura con el exterior y puedo decir que al menos durante 6 horas estuvo funcionando y todavía la batería marcaba 2 rayas así que creo que podría durar muchísimo más aunque es cierto que estaban recién estrenados y yo sé cómo va cayendo la batería y tampoco te dan indicaciones de cómo cuidarla por qué supongo que como todas las baterías habrá que dejarlas caer de vez en cuando. maraviilloso calorcito que se agradece!! Se puede dejar apagado y encender a demanda, empieza a calentar al segundo, nonte hace esperar. Viene con un cable usb doble "bifurcado", es decir, con un solo enchufe cargas los dos a la vez y se completa relativamente rápido, depende del enchufe utilizado. anatómicamente muy adaptados a la palma de la mano al principio me parecían pequeñitos pero es suficiente y además se guardan muy bien en el bolsillo mucho mejor que otros también pueden utilizarlos así los niños . con el imán que tienen los puedes juntar y así se pueden guardar en una pequeña bolsa que trae también el pac además de unos cordones que les puedes poner y podrías llevarlos colgados en las muñecas para no perderlos por ejemplo en el caso de los niños. no pueden estar mejor pensados ,la verdad, si sueles salir a andar o vives en sitios fríos, TOTALMENTE RECOMENDABLE Read more

I really like these hand warmers. They are worlds better than the old lighter fluid types I used for decades. They charge via usbc, and the charge can last for a couple days of moderate use. No more lighter fluid smell and the hassle of filling it and lighting the wick, just press the button for fast heat. They are more compact, and can be slid into a pair of gloves. If you want a product that's easy to use, puts out decent heat this is a great purchase. They have been a big hit when given as gifts. Their value for keeping your hands warm greatly exceeds the cost. Read more

We live on extensive rural acreage within a great lakes snowbelt. Every winter we go through many pairs of bagged granular hand warmers. With our active outdoor life, the bags are sometimes damaged enough to leak contents and when Ziploc-stored to extend use, there's no way to tell one bag from another or how much 'heat life' is left. So I tried the OCOOPA UT3 light rechargeable electric warmers. At first, I had problems understanding the very skimy User's Manual - and I emailed OCOOPA customer service, asking for help understanding button function and operation. They responded promptly with detailed instruction well written. In the interim, I was able to comprehend operation after viewing a YouTube video review. My first field trial of the UT3 was in an unheated (below freezing) hunting blind, wearing gloves. I set the heat on 'high' (three red lights) and soon found it to be warmer than necessary. I switched to 'medium' heat, and found that too was more than I needed, despite the frosty atmosphere. The heaters actually kept my gloved hands perfectly warm on 'low' heat setting. Without the gloves, the 'mid' setting was enough. And I would assume that working with icy-gripped equipment (i.e. Snowblowing), the 'high' setting would work fine. Recharging (blinking blue light) and battery checking is easy. In sum, these hand warmers exceeded my expectations. They are far better (read: warmer, more durable, easily checked, rechargeable, inexpensive/use) than the granular-filled heaters. And the service response was clear and prompt. - The Duffian Read more

Questi scaldamani sono ottimi, si ricaricano abbastanza velocemente e durano a lungo. Sono molto caldi, hanno tre livelli di riscaldamento ma io li metto sempre a uno perchè già così sono caldissimi. Read more

Perfect for the upcoming winter! Long battery life and the magnet upgrade is very convenient compared to the last hand warmers I had! Read more

Absolutely fantastic little gadgets! I’ve had hand warmers for a few years since developing secondary Reynauds and couldn’t be without them in winter. These are a big improvement on my old ones. They really do heat up in 3 seconds, it’s amazing! The hottest setting is boiling and probably too hot for me once I’ve warmed my white fingers up but that’s a bonus as it means the batteries will last longer. They only heat on one side but you can put them together to make one big one if you’d prefer. They fit nicely in gloves and come with a nice little bag to keep them in. The fact that you can charge them at the same time is a bonus. I’ve included a photo of the box with battery details etc. on it. These are going to be a lifesaver for me this winter…no more pain!!
