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.

    Wonderful product here- for folks living in the great state of North Dakota. (Or any other cold winter climate state.)

    My question is, can the battery be replaced\recycled by the user or must the whole device be chucked in the recycle bin?

    @Jeff Hi, Jeff. The unit will take a minimum of 500 full charges but once the battery has lived its life, the device would need to be recycled, much like any other power bank might. Nonetheless, as compared to the ecological impact of single-use, disposable hand warmers, the smart warmer is a far more green and versatile product.

    500 charge cycles is pretty amazing nonetheless! Thanks for the reply, will be buying these for Christmas for people here in the North.

    Nifty idea. Thinking "gift" for my hubby who works outside year-round in New England and sometimes can't be reached because his phone is dead.

    Any known issues with catching fire (like e-cigs do)?

    Does it emit any low-level radiation, in comparison or addition to that of cell phones?

    Great point about recyclability vs. those wasteful disposable heater packs. I'd still rather this be recyclable or somehow reusable, but maybe in a future version?
