    A friend of mine received these as a gift and demo’ed one for me recently. I decided then and there I wanted it! I ordered two of these, not realizing they came in a 2-pack, but I’m keeping both sets for backup so when one is charging, I’ll have the other still available. It has three heat settings, and the highest one is more than most can handle. Setting 1 or 2 is plenty warm. It charges with a USB-C cord – supplied, and comes out of the box already charged and ready to use. No need to even read the instructions. Just hold down the power button for a couple seconds and it starts, and then press the power button repeatedly until you get to the desired heat setting. It comes with a lanyard for each warmer and a fabric pouch to use while you’re using it. Heat lasts a good long while. What a useful, simple device for cold winter days! I’ll be using them inside my gloves for walking the dog. It’s even great for just warming your hands while sitting around the house! Highly recommended!

    Great little handwarmers that heat up very quickly, last a reasonable amount of time and feel good in the hand. Perfect for when your walking around in winter and have them in your pockets to keep your fingers nice and warm. Also good for those who are into Swimming, Esports that require warm hands for improved dexterity. Would recommend to all as comparative products Ive seen in shops are twice the price for half of the product

    These handwarmers are very effective at easing carpal tunnel hand pain at night. When my hands hurt I grab these and within a few minutes the heat eases the pain. The lowest heat level gets a little bit warmer than I would prefer but if using with gloves outside the heat level would be great. I was using disposable hand warmers so am glad I found something that is reusable and in a fun lavender color.

    These Ocoopa rechargeable hand warmers are unbelievable! Once received, they charge quickly and will be ready for use in no time. They have three adjustable heat settings depending on your comfort level and when I say they heat up within seconds of being turned on, it is literally seconds. They are small enough to fit in your pockets, have a great magnetic design to stick together when you’re not home (so one doesn’t get lost), and the ***HEAT*** lasts up to 8 hours!

    Now, if you’re like me and have kids who have played or play sports in the fall/winter months or go to those cold tailgate sport games, this is a great buy! I am always cold and can never keep my feet or hands warm. This has been a great addition to my keep warm gear and I will never look back, I will never go without these hand warmers. For the quality of this product I am shocked they are priced so low. Do NOT wait. If you are on the fence about purchasing them, do it. You will not regret it!

    Irgendwo habe ich noch übliche Handwärmer, die man mit heißem Wasser wieder auflädt. Nutzen tue ich sie leider nie. Entweder weil ich sie vergesse oder sie nicht einsatzbereit sind. Oder ich einfach zu bequem bin, sie wieder im Topf mit Wasser so lange zu erhitzen, bis sie wieder nutzbar sind. Seit meinem letzten Umzug sind sie verschollen, ansonsten hätte ich sie genau jetzt aus Neugierde wieder hervorgekramt.
    Geärgert habe ich mich aber im Winter schon öfter, dass ich keine Handwärmer dabei hatte. Der Vorteil der elektrischen Handwärmer: Man kann sie einfach in der Jackentasche lassen, ohne dass man Sorge haben muss, dass sie versehentlich ausgelöst werden. Dabei hilft auch eine kleine Transport- und Aufbewahrungstasche.

    Die Handwärmer sind kleiner als gedacht und passen bequem in die Hand.
    Ein Doppelklick auf den Bedienknopf zeigt den Ladezustand an (mit 3 blauen LED-Punkten).
    Ein langer Druck auf den Bedienknopf aktiviert das Aufheizen. Mit jeweils einem weiteren Druck auf den Knopf lässt sich die Heizstufe verstellen. Derer gibt es drei: Niedrig (42 Grad). Mittel (46 Grad). Hoch (52 Grad). Angezeigt mit jeweils ein bis drei roten LEDs. Ein langer Druck auf den Knopf deaktiviert das Gerät. Bereits die niedrige Stufe lässt das Gerät recht warm werden. Bei eisig kalten Fingern im Winter könnte es schon fast zu warm werden. Allerdings ist hier dann zusätzlich noch die deutlich kühlere Außentemperatur zu berücksichtigen, d.h. das Gerät muss dann mal eben 25 Grad oder mehr zusätzliche Temperaturdifferenz überbrücken. Eine echte Aussage zum Verhalten kann ich daher erst im Winter treffen.

    Die kleinen Heizpads erwärmen sich sehr schnell nach dem Einschalten, kühlen sich nach dem Ausschalten aber auch relativ schnell wieder ab. Beheizt ist nur die schwarze, konkave Oberseite.
    Extrem überrascht hat mich die angegebene Akkulaufzeit von 4h bei höchster Heizstufe, bis zu 8h bei niedrigster Stufe. Sollte wirklich ein 2500mAh Akku in jedem der kleinen Handwärmer eingebaut sein, dürfte Größe und Gewicht größtenteils auf den Akku entfallen. Ich bin gespannt auf den Winter.
    In meinen Tests hatte ich die Akkus nicht aufgeladen und sie zeigen seit Beginn der Tests immer noch dieselbe Ladestufe an. Die kleinen Dinger können auf jeden Fall länger für warme Finger sorgen als die üblichen Handwärmer. Damit hatte ich nicht so wirklich gerechnet.

    Weitere positive Aspekte:
    – Die Ladebuchsen sind mit einem Silikonstöpsel geschützt, d.h. Schlüssel und Co können keinen Kurzschluss erzeugen.
    – Die Handwärmer können um 180 Grad gegeneinander gedreht gegeneinander magnetisch befestigt werden. So lassen sie sich platzsparend im Transportbeutel unterbringen oder man hat einen größeren Handwärmer für große Hände. Benötigt man halt noch ein weiteres Set, wenn man die “großen” Handwärmer bevorzugt.

    Von mir bisher volle 5 Sterne. Im Winter dann ein Update 🙂

    These hand warmers are more powerful than I expected. I don’t use them higher than the first setting since they get so warm. The battery lasts a long time. I keep them in my pockets as they are too large for my gloves. I keep them at my desk at work since my hands get cold.

    First, let me say that these things work. They are easy to charge, and so far the battery life seems very good. I put one in a shirt pocket, another in a pants pocket and went for my usual 4 mile walk in lower 30s temps, and i was very comfortable using only 1 (out of 3) dots of power – lowest setting. I gave these 4 stars instead of 5 because I bought them for glove warmers; i have a real problem with my hands getting cold. For that purpose, they are less than ideal for two reasons. First, while they will fit in my gloves and it is possible to use them as glove warmers, they take up almost my entire palm, so holding anything, even a mug of coffee, is very difficult. Second, only one side of the warmer gets warm (the curved side – black on my model). That’s okay, because having the warm side down next to bare skin in the glove is actually too hot, uncomfortably hot. Putting the white (flat) side next to my skin and letting the colored side just warm the glove worked fine – except for the difficulty in holding anything. Bottom line – as pocket warmers, they are great. As glove warmers, not so much. But I’m still glad I bought them and on my cold winters’ walks, they’ll be a much appreciated aid.
