Customer Ratings & Reviews

Great little device, love that its multi-purpose. Bought one a month ago (on sale for $10) and so far it seems to be a good value, so I bought a second one for skiing and camping. Small battery capacity but will provide about 75% charge to my s23+. Hand warmer function works decent also, but have not tested it thoroughly yet. Only downside is that there is one button to control both the power and temp setting. This means to turn the temperature down, you have to cycle all the way up to the highest setting before it restarts at the lowest. Overall, seems like a good value and I hope it lasts.

It works perfectly, it's very practical, and I can recharge it easily. Its screen shows the battery level, which is very useful. I think it would be extremely useful for those who enjoy hunting.

This has been a great addition to my gadgets. I have several portable battery packs, but, unless I'm traveling, I tend to leave them at home (where they don't do me any good). With the additional feature of being a hand warmer, which has been so great to have, I have been keeping this in my purse, so it's always handy - whether it's to warm my hands or connect to my phone to charge. The other day I SAVED the day for a friend, because I had this with me. After she charged her phone, I explained it was also a hand warmer and then she had to have one. ha!

Seriously this is one of the better products I have ever bought! We play outside a lot in the winter and this little hand warmer heats up in literally seconds!! Just to have a little heat source when that chill takes over is absolutely fantastic! To charge it all you need to do is plug it in!! No batteries to deal with!! We need more so we don’t have to share ☺️

I bought this as a hand warmer while on sale for Deal of the Day ($9.99 vs. $24.99). I easily freeze so on any cold day when I'm outside, or even at the poker tables where some rooms can get really cold, this little guy comes in "handy". I like the battery pecentage that it shows on the little screen, amd the fact that i can adjust the temp. The bonus was that it can also charge my phone as it's a 5,000 mAh charger as well! Another bonus for use in the poker room.

I bought this thinking it wasn't going to be anything too crazy but this is actually pretty good. It gets warm very fast and you can set the temperature to whatever you want and it only takes a few seconds to get to temperature. I would advise not to charge your phone and use the heat settings, as it will drain the battery life. I mainly use it for the heat function and it's great!

This hand warmer heats up quickly and is easy to use. I will say the heating eats up more of the battery than I would like, BUT I mostly use it while at my desk and when I’m on vacation in a city that’s a little chilly. I love that is is a charger and that feature has already saved me a few times.

I love it! So easy to use! I recently have been using it out at the ballfield. Has not let me down!

Great capacity and charges fast. Light weight and a compact packaging.

Hand-warming and backup charger work well after you figure out how to use it. Poor instructions.

This device works very effectively. It holds a charge for a very long time and works well as a hand warmer.

This little hand warmer is amazing. Very worth the deal when on sale. It gets up to a toasty 132 degrees and can last a couple hours at that setting. It also recharges in a couple hours.

I needed a backup battery pack for my original. This met my needs and can be used as a hand warmer. Got this for $10.00. Really can't beat that price.

Energizer - 5,000mAh 10W 2-in-1 Rechargeable Hand Warmer 8hrs Warmth + Universal Portable Battery Charger/Power Bank w/ LCD screen - Black This warmer works GREAT last long and charges fast.

I got this on sale when it was $9.99, so it was quite a steal. It heats up pretty fast and charges well as well. I would recommend.

Works as expected. My first time using i had it at the highest warmth setting and it lasted only 3+ hours. So next time I'll dial it down and see how long it lasts.

Energizer Recharge batteries are really reliable. They hold charge well and last through multiple uses without dropping power quickly. I use them in remotes, toys, and gadgets they’re consistent and don’t leak. For the price, they’re definitely worth it, especially if you recharge them instead of buying disposables all the time. Overall, solid performance and good value.

The rechargeable hand warmer is very effective - it generates great heat. It does take a while to charge so if you let the battery get very low be prepared to give it several hours to get back to full capacity. It's a little big so it doesn't really fit inside a glove, but is great in a jacket pocket. For warmth and recharging capability instead of batteries I definitely recommend. And the sale price was great.

Battery life worked pretty well. Used it for two travel ball games and had 17% battery left so works well for our use case.

Works well and just the right size I would recommend to others.
