smart warmer


I bought this for my wife, her hands are always cold and I know because she is always trying to warm them up on me, don't take me wrong I like her touching me, but not on my side with freezing hands but more importantly she loves it and uses it. Thanks for the product.


Smart Warmer


I have both severe arthritis and Raynaud’s disease in both hands. Both are relieved with heat and these warmers do an exceptional job.


How Convenience


I two- in- one. I live in Wisconsin where we have cold winters. It is nice to have a hand warmer on me and a cellphone charger. But I hated having to carry so many things on me. Well, I don't have to with this item anymore. Love it.

The Smart Warmer Story

Back-up battery life—and warmth.

Hands-On Warmth

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.
