It takes overnight to fully charge from about 20% and it definitely has a while to warm up. I found a few other types from Amazon that work a lot faster but it's impossible to tell what mode it's on. So I decided on this one. It's okay for a hand warmer. Definitely a little bit bulky and definitely takes a while to get warmed up. Definitely better to keep it in your pocket as I tried it at about 30° one morning and it felt like the tiniest whisperer of heat was touching my hands even on full blast, but 5 minutes in my pocket and definitely worked a lot better. Those little disposable and warmers that get activated by the air definitely work better but don't like the environmental impact

I purchased two of these and they are perfect for keeping my hands warm and taking the edge off in the early morning as I’m a service electrician that works outside in all weather conditions.

I like this thing. The four heat settings are a cool feature but the difference in temperature isn’t significant between 1-4 and I think High/Low would’ve sufficed. The silicone case needs to be handled to break it in to take the powdery feel off. Love that it’s rechargeable. I just keep it on max in my coat pocket. Would’ve liked max settkng yo be warmer but it still keepsa comfortable temp.

Works good battery does not run quite as long as it says but close

This hand warmer works pretty well. It has several settings for temperature. It comes in a water resistant rubber holder. The buttons can be pressed through the rubber holder for convenience. The battery life between charges depends on the setting that you choose. I have used it at a high school hockey game as a spectator trying to keep my hands warm and if you have it in a hoodie pouch you can keep both hands warm. I bought this product on Best Buy's deal of the day at a great price.

It warms up faster than a heated car seat, and it has quite a useful battery life. The button to turn it on was a lityle finnicky on the one I bought. I got it for my girlfriend and she squealed with excitement!

Got this for long trip through the arctic. Worked well and kept warm for a long time.

Got one for my dad and brother, the device works very well for them as they like to hunt. It heats up quick and the battery lasts just about long as the packaging claims.

Cool prodcut, it just doesnt get warm enough for my liking. Takes too long to charge. But waterproof works as advertized. Confy to hold, charges quite fast. Wouldnt use it for camping or long outdoor outages.

I wish I knew this existed sooner! This tiny thing gets pleasantly toasty, and lasts a good amount of time. Very useful in a pinch for quick warmth. The device charges fairly quickly through micro USB. I gifted one of these to a friend who is also extra sensitive to the cold and she loves it!

Stays charged for a long time without use. Unlike some battery packs. Once I went to use it I only needed level 3 out of 4 and it stayed charged for a couple uses. Around 6 hours total. Gets pretty hot honestly. I would rather have a long hold button to activate as I have accidentally pressed the button once and it came on. Then had to cycle through to turn it off.

Excellent Product for the price! Produces Great Heat Fast/Compact Light Weight makes this item a Must Have!

Takes a good long time to charge fully but useful in keeping my hands warm!

Overall this is a great product heats up very quick and feels pretty light in the hand.

This hand warmer is great for keeping my mother’s hands warm.

Perfect for the cold weather easy to use  just charge it n your ready to go 

I had never seen a reusable hand warmer like this before so i thought it was pretty unique. It definitely great for the winder! I battery life isn't TOO long on it but that's to be expected with how power costly it is to produce heat. Only downside is it's micro USB and not USB-C to charge.

good ithem for heat the hands and feets, very cheap

I took one of these with me on my last hunting trip and nothing makes your experience better like warm hands! This warms up quickly and lasts long! I might get a second one just to have one for each pocket. My only gripe is that there isnt ‘hard’ on off switch so it can turn on while its in your bag. I 3d printed a small piece to isolate the button and that works, but from stock should have a way to disable the on/off button manually

My work gets cold, grabbed this to help jeep warm. Lowest setting lasts my entire shift pretty much. Perfect my my use
