Hand Warmer, 2 in 1 Double Sided Electric Pocket Hand Warmers Rechargeable 5200 mAh Power Bank Portable USB Battery Charger for Women Men iPhone 11 Pro Max X XS Max XS Samsung Galaxy Android, Blue

have tried to hand warmer and it seems to get quite hot. The real test will be in the winter. Charger worked well

This flat egg got wonderfully warm, remained warm for well over two hours, and was easy to recharge. The only drawback was that it was easy to drop.

My hands are always ice cold, literally start to turn blue in my nail beds so when my nurse advised me of hand warmers I ran straight to Amazon! I've had this one for a few months now and it works great! I've used it a few times to charge my phone when I'm desperate but for the most part I save it to warm my hands and it works great for both purposes! Would definitely buy again! I have a Samsung Galaxy S8 if that helps you decide!

Used it to keep hands warm when i work the freezer. Stsys hot for ONLY 2HOURS... DONT WASTE YOUR MONEY...

Works well, down a star because I did not receive the pouch. Not worth sending back. I'll use an old sock. It does get almost too hot

I don’t actually use this for hand warming, but to keep my phone battery warm enough not to drain completely while in my pocket outdoors. I put the warmer in an old wool mitten and the phone next to it, it does not get super hot. We have had record cold this winter and after a couple times having my phone die while outside, even in an inside pocket, I finally got a clue. I keep a short charging cord with it so I can use the power bank to recharge if needed, but so far I’ve gotten normal battery life from the phone by keeping it slightly warmer. Also it comes in a box that says “dolphin hand warmer” which my kid found endlessly amusing (dolphins don’t have hands, as a kindergartner will tell you all day long).

Arrived on-time. Labeled 'Made in China." Two ports on device, one to charge the device itself, one to charge exterior devices via USB. Charging cord enclosed with shipment did not work, used a different cord to charge. Instructions enclosed in box are poorly translated, likely Babelfish or another free online service. Gets warm, but not hot (have a different charger that's easier to operate and gets hotter).

I have Reynards disease and my hands will nearly freeze in temperature is below 70°. I need to take our Parrot’s outside in colder weather. This device kept my hands warm for two hours the first day I used it and still wasn’t out of battery power. I did not receive the little velvet bag that supposed to come with the unit, but I’m not complaining. I have Reynauds disease and my hands will nearly freeze in temperatures below 70°.
