small, 2x units, great for inside gloves. Toasty.
small, 2x units, great for inside gloves. Warm & toasty. I also have the larger OCOOPA units, which are very good, but too large for inside gloves. THESE units are 2x smaller units which fit very well INSIDE gloves. They are magnetic for keeping together, and come with lanyards, carry protection bag and a Dual charging cable (so BOTH can be charged simultaneously). They are small yet powerful enough to heat up well (bear in mind they are Inside a glove so you wouldn't want these too hot!) They have power indication for heat and battery remaining. In test, they worked for a long time. SUMMARY: OCOOPA is a brand I trust (this is a hot item with a lithium battery!) so would never bay any CHeapo brand. These fit well inside a gloves and come complete with everything required. These work very well. WOULD recommend.

Great product
Bought as a gift for my son, who does a lot of walking to get to and from college. Quickly charges and packs quite the punch when turned on. Easy to operate, simple storage, and great heat output. Would definitely recommend.

Love them
Heat up in no time. Kept my hands warm in the car while waiting in the car park in the snow. Very effective when in your pockets. They felt like they got hot then cooled a little then got hot again so they didn't burn my hands. When turned off they cooled down quickly so could be put away near enough straight away. Easy to charge with the supplied cable and can be used with or without the hand straps. Level 3 was too warm for more than a few seconds but I think that might be the setting for gloves with a pocket in the back. I was contemplating putting them down the sides of my boots for a short while to warm my feet up but didn't do it but would defo try next time they get cold when I'm out and NOT walking . Could warm shoes up b4 putting them on, I would think, or warm body parts other than hands when needed. Versatile and portable and well worth the money paid. Looking at getting more for family.

Hit & miss
Bought these but had to return them after trying, as one of the pair was faulty. (Perhaps foolishly) I bought a second identical pair from same seller and was relieved to find these replacements both work very well. Nice little gadget. Heats up only on one side but this is actually better when using. Good size to slip in gloves. Comes with wrist strap & 1 mini bag to keep them in when not in use. Magnetic side sticks pair together for storing which is useful. They charge well & last a good few hours continual use, tho depends on temperature level used. Easy to use with 3 heat setting, but confusing differences between levels of heat. Level of heat appears to depend on respective setting’s frequency of the heat generator switching off & on to regulate temperature. Warning: Highest level can get very/too hot but also alternates on/off, so not continuous. But when it gets hottest, it’s painfully (damaging to skin?) hot. I think trial & error & getting used to them is needed but overall, they’re good for what I need them for so I’ll be keeping them.

Toasty warm hands with no fuss
I bought these for my boyfriend who gets very cold hands when walking in the winter. He loves them and always has them in a pocket to slip into his gloves when his hands start to get cold. They are quite small and fit in the palm of his hand nicely but they put out a decent amount of heat and last for a long time before needing to be charged.

I absolutely love the OCOOPA AI Magnetic Hand Warmers! The battery life is long-lasting, and I can comfortably use them for hours. On the highest setting, they get very hot, but the middle setting is perfect for comfort without overheating. Charging is quick and easy, taking less than an hour, and the included dual-ended charger allows both warmers to charge simultaneously. The hand warmers are lightweight, compact, and easily fit into pockets without feeling bulky. One of my favorite features is the arm loops, which let me carry the warmers hands-free—perfect when you need your hands for other tasks. The design is both cute and practical. The pattern on the front hasn’t faded or discolored, and I always get compliments on them. Many people have asked me where I purchased them and if I recommend them—I do, wholeheartedly. I would suggest choosing a darker color instead of white, as white can get dirty more easily. Each warmer heats on one side, but the magnetic feature allows them to attach to each other, so you can keep your palms and fingers warm simultaneously or fold your hands together. Using one at a time can give you 8–9 hours of warmth, and both together last around 4 hours. Overall, these are the best hand warmers I’ve ever owned. They are stylish, girly, easy to carry, and incredibly practical. I highly recommend them to anyone looking for compact, effective, and cute hand warmers.

I just received them, and everything is working perfectly fine. The fact that the charger comes with 2 cables is quite useful. Hopefully, it will last a long time.

Habe es meinen Mädels gekauft zum 01. Adventskalender Türchen und beide lieben diese Taschenwärmer! Einfach aufladen und es ist betriebsbereit. Die anderen "klassischen" Taschenwärmer zum aufkochen haben mich so genervt... mit diesen steht man nicht in der Küche herum...die Töpfe verkalken nicht. Und sie werden auch sehr schnell warm :)
