BIUBLE Hand Warmers,8000mAh Long-Lasting Heating Rechargeable Electric USB Hand Warmer Great for Skiing,Climbing,Hiking,Winter Gift

Final Update: This great little hand warmer will work best (and longest) if you charge it shoprtly before your intended use. My experiment was to charge it a day and a half before using it on the golf course. It had lost about 25% of it's charge. Still had enough power to get me through a round of golf during 37 degree temperatures. BTW: this loss of charge is endemic to these devices (just like cell phones) but it is still far superior in the BiUBLE warmer than in other versions. Worked so well that two more golfing buddies are going to order the same hand warmer.UPDATE TO ORIGINAL REVIEW:This is even better than I first thought. It stayed hot for over SEVEN HOURS. Compare this to the ones that my golfing buddies bought and it is amazing. In fact, two of my golfing buddies have asked me to buy the Biuble hand warmer for them which I have done.Originally purchased an EasySo hand warmer. BAD decision. Sent it back and got this one. Works great. 2 hours to charge. It is now 4 hours after turning it on and it is going strong with more than 1/3 battery life left - more than enough for a full 18 holes round of golf. AND it gets WARM. Left it in pants pocket while driving during this initial test. Within 10 minutes I had to take it out of pant pocket and put it in jacket pocket. Luvv'it!!In fact, I just ordered two more for Christmas presents!!! FIVE STARS, KIDS, FIVE STARS!

Overall a very nice product. Easy to use. It has an on and off switch and nothing more. Great for someone who like to keep things simple. It's a good size and has a nice, smooth texture to it. Will easily fit in a hand bag and pocket.I don't love that there is only one heat setting. I'd love to be able to choose how warm it gets. Doesn't heat up super fast, but neither of these things are a deal breaker. The only thing I don't like, and the reason it has four stars instead of five, is that the on/off/battery indicator LED lights are incredibly bright. Hurt my eyes bright. And if I have it outside on a dark winter evening, it's going to illuminate even more.

It gets warm but not nearly warm enough . I have another brand that does a lot better for the same price . That being said if the battery is really 8000 mah then it’s a damn good deal as a phone charger in itself . The rest is an added bonus . It just want consistently stay at the very warm temp I need it to . It fluctuates badly .

We took two of them to breckenridge Colorado this year and they worked out great. I put it in my chest pocket and it added a decent level of warmth to my jacket. It’s also great to hold when you are waiting for the bus.

Very small, but very hot. Don’t be fooled by my small hands, this hand warmer is about the size of a computer mouse BUT it gets very hot. Perfect for camping, sporting events, hunting, or in my case, a chilly office. It’s small enough to easily fit in my purse so I can tote it with me when I need it. I am highly satisfied. It also arrived fast with my Prime free two day shipping.

Wonderful product! TI bought this for my son who is a gamer and he loves it! It works incredibly well as a hand warmer and it will also charge your phone! It is a powerful little product for a fabulous price!! Rec'd it really fast as well! :) Love it and am going to buy another one for ME! I would def recommend this product!

It isn't as hot as i thought it would have been, but you get used to it.I recommend that you put the temperature ranges as one of the statistics.

After series of comparison, I finally placed order for BIUBLE as a gift to a friend live in SF. The main reason for choosing BIUBLE is because it not so expensive as the pouches. Also, I do like the compact the design. So does my friend. She told me it's lightweight, portable, easy to charge and comfortable temperature setting. She really like this BD gift. I'm happy I choose this right gadget .
