Survival Frog Rechargeable Hand Warmer - 5200 mAh USB Power Bank & Charger for iPhone & Android - Double Sided Electric Hand Warmer - Great for Camping, Outdoors - Gifts for Women, Men (1 Pack, Black)

Features 2-in-1 SURVIVOR TOOL: Your hands are the most vulnerable in the cold, and this 2in1 survivor tool puts out enough heat to keep them warm even in freezing temperatures.

You can also use our handwarmers to fuel or recharge your chargeable devices as a portable power bank.

RECHARGEABLE HAND WARMERS: When it runs out of power, plug the handwarmer into an outlet using the included USB charging cable to bring it back to full power.

It is much more cost-effective than disposable hand warmers which only last a couple of hours and then get thrown in the trash.

HIGH-PERFORMANCE: This double-sided and high-performance hand warmer warms hands in minutes while providing backup power for your cell phone.

It runs continuously for 2-4 warming hours, depending on which temperature it is set.

That's enough time to last an entire workday, long car ride, or hiking trip.

EASY TO USE: There's only one button on this hand warmer that turns it on and off and cycles between three adjustable heat settings.

It's that simple.
