So nice not to have to mess with lighter fluid and flame.
Good but not as good as it claims

This product gets very warm but doesn’t last near as long as the description. A full charge lasts about 60-90 minutes as a warmer. I ordered two but returned one because it didn’t hold a charge for even 30 minutes. I’ve only used it to charge a phone one time which worked fine.
Great invention!!

My daughter works at a horse rescue and is out in the cold for extended periods of time. She is always freezing cold so this was a great gift for her. She also loves that she can charge her phone! Love this!!!!
Best item for the folks with cold hands!

We use the pocket warmer daily for countless hours since our purchase months ago. It works as promised for 6-7 hours & has been accidentally dropped several times with no damage to it's performance. Great investment!

4400mAh Pocket Warmer Power Bank

This product is currently out of stock

This pocket-sized two-in-one is a hand warmer phone charger. Recharge a phone up to two times, or keep hands warm for anywhere between four to six hours.

Smart Warmer

Folks on the move will appreciate Smart Warmer’s two must-have functions. This hand warmer phone charger does both jobs in a pocket-sized design.

Whether you use it for a warm boost during commutes, at sporting events, or as a power bank to recharge your phone, the combined functionality makes this two-in-one problem solver great to keep handy.

The 4400 mAh Smart Warmer charges a phone twice or warms your hands for around four to six hours (not both at the same time). The same goes for the 2000 mAh battery, which provides one charge or three to four hours of toasty goodness.

Even though you can’t use the charging and warming functions at the same time, the device stays warm for a while after you turn it off, so you still benefit from the heat.

It’s a simple (but smart) way to power up—and warm up—in one small device.
