Rechargeable Electric Hand Warmer with Built In Power Bank and Digital LED Display

Portable Hand Warmer That Heats Both Sides and Charges Your Phone

A fingers go numb within minutes of stepping outside in the cold. You can't grip your keys, type a reply, or hold anything without fumbling. Keep hands warm while commuting, sitting through winter events, or waiting outdoors in the cold.

It heats both sides at once when you press the button through carbon crystal elements. Cycle through three temperature gears while the display tracks your setting and battery level. Plug your phone in and the 3500mAh battery starts charging it right away.

The curved body fits naturally in your palm and slides into coat pockets or gloves. The ABS and aluminum alloy shell help resists drops, scratches, and cold weather damage. 

These three gears let you dial heat up or down to match the conditions outside. The digital LED display shows battery level and heat setting in real time, and a charging cable comes in the box ready to use.

• CARBON CRYSTAL HEATING: Elements on both sides of the warmer heat up together so both hands stay warm at the same time.
  
  
• THREE TEMPERATURE GEARS: One button cycles through low, medium, and high heat so you match the output to how cold it is outside.
  
  
• 3500MAH BACKUP CHARGER: Built-in battery powers the heating function and charges your phone through the port when outlets are nowhere nearby.
  
  
• REAL-TIME DIGITAL DISPLAY: LED screen shows your current temperature gear and remaining battery percentage so you always know where you stand.
  
  
• CURVED PALM-FIT SHAPE: Contoured body sits comfortably in one hand and slides into coat pockets, bags, or gloves without adding bulk.
  
  
• ABS AND ALUMINUM ALLOY SHELL: Outer body handles everyday drops, scratches, and cold weather exposure without cracking or wearing down over time.

Can I charge my phone and use the heating function at the same time?
Yes, the 3500mAh battery supports both functions at once so you can keep your hands warm and charge your phone through the port without having to choose between the two.

How do I know what heat setting I am on and how much battery is left?
The digital LED display shows your current temperature gear and remaining battery percentage in real time so you can check both at a glance without guessing.
