Karecel Hand Warmers Rechargeable 2 Pack, 10400mAh Double-Sided Heat Electric Handwarmers Powerbank, 4-inch Full-Surface Heat, Portable Camping Hand Warmers, Men Gifts for Christmas, Winter Essentials

Dual Functionality - Power Bank and Hand Warmer Rechargeable: This versatile electric hand warmer doubles as a USB power bank for convenient emergency use. The product also includes a USB-C cable with a splitter, allowing you to charge two devices simultaneously. True Double-Sided Heating: Moving beyond "Requires Assembly dual-Sided Heating" products on the market that require pairing two devices to achieve dual-sided heating—since they only heat one side when used alone. Each of our units delivers true dual-sided heating for full-coverage warmth. True 2 Pack Hand Warmers: Differing from SINGLE-sided heating "2 pack." Most so-called 2-pack on the market are simply one complete product split in half. To achieve dual-sided heating, you'd need to connect the halves with magnetic or snap-on. Our set includes TWO genuinely independent, slim hand warmers. Each provides instant double sided heating for all-around warmth. Full-Surface Heating & Portable Design: Moving beyond most hand warmers on the market that rely on small central heating points, our innovative design features TWO 4-inch aluminum heating plates encircling the entire device, creating a broad, uniform heating surface. This allows heat to penetrate gloves or thick clothing, providing sustained warmth even in extreme cold conditions. This portable hand warmer design with palm size 1 x 2.4 x 4 inches easy to take-on-go when you need. 10,400mAh Ultra-High Battery Capacity & AI Smart Heating: Say goodbye to single-use hand warmers, this 2-pack rechargeable, reusable hand warmer features 5200mAh batteries*2 with 3 temperature settings for instant, precise heating. Powered by an AI chip, it actively adjusts temperature for all-day comfort and safe operation. At the lowest setting, it delivers up to 11 hours*2 of continuous use. ›See more product details ›See more product details
