2 In 1 Hand Warmer and 5000mAh Power Bank with Double-Sided 52°C Heat

This 2-in-1 retro hand warmer combines a double-sided heating pad with a 5000mAh power bank, so you can keep your hands warm and keep your phone charged from the same compact device. It heats up to 52°C in around 30 seconds to 1 minute when the warming mode is switched on, and the real-time temperature is shown on the digital display. After a full charge, it holds heat for approximately 3.5 to 4.5 hours at 20°C. The body measures 69 x 74 x 34mm and is made from flame-retardant ABS with a high thermal conductivity aluminium alloy plate. A micro USB cable, a flannel bag, and the power supply itself are included, making it a practical choice for winter walks, commuting, outdoor events, or a Christmas gift.

Features and Construction

The hand warmer is built around two functions: warming both sides of your hands and charging a mobile phone through its output interface. The controls are straightforward, with separate buttons for heat mode and power bank mode. A chip manages temperature automatically during charging, and the flame-retardant ABS shell is chosen to resist high temperatures. The aluminium alloy inner plate is used for its high thermal conductivity, helping to spread heat across the surface rather than concentrating it in one spot.

Material and Build

The outer casing is made from flame-retardant ABS, which is used in the construction to help prevent high temperatures from affecting the body. Inside, a high thermal conductivity aluminium alloy layer is responsible for transferring heat evenly across the warming surface. A high temperature protection function stops the heating element once it reaches 52°C, and the temperature is automatically controlled by the chip during charging. There are two buttons on the device: the right button controls heating and temperature display, while the left button controls mobile power mode and battery display. An input and an output interface sit on the right side.

Size and Practical Fit

With dimensions of 69 x 74 x 34mm, the unit is small enough to hold in one hand or slip into a coat pocket. The double-sided heating warms the whole hand rather than just the palm, which suits wearing as a pocket warmer or holding while sitting at a desk. The 5000mAh battery capacity provides the power for both heating and phone charging, and the 5V/2A input allows recharging through the supplied micro USB cable. The included flannel bag offers a simple way to store the hand warmer and cable together between uses.

Uses and Placement

This device is suited to cold-weather situations where you want warmth without carrying separate gadgets. It works as a personal hand warmer for outdoor activities and as a backup power bank for a mobile phone. Because it is a single unit with two modes, it can stay in a bag or pocket and be used as needed. The digital display shows both temperature and battery level, so you can check the status at a glance without guessing.

Event or Professional Use

For outdoor events, winter sports, or working in cold conditions, the hand warmer can be switched on and kept in a pocket or held in the hand. The 52°C target temperature and the 3.5 to 4.5 hour running time at 20°C make it suitable for a morning or afternoon outside. The mobile power mode can charge a phone through the output interface if the battery on your phone runs low. The high temperature protection function stops heating at 52°C and restarts only when you turn it on again, which keeps the surface within its designed range.

Everyday Home Use

At home, the hand warmer can be used while reading, working at a computer, or watching television in an unheated room. It can also be kept in a hallway or by a door for use before going outside. The 5000mAh capacity means it can serve as a spare power bank for a phone during a power cut or when travelling. The compact 69 x 74 x 34mm size means it does not take up much space on a desk or in a drawer, and the flannel bag keeps it tidy when not in use.

Benefits and Buying Value

The main benefit is having two useful functions in one body: a hand warmer and a power bank. Instead of carrying a separate battery pack and a separate warmer, the 5000mAh unit covers both. The rechargeable design means it can be used again after charging, and the 5V/2A input is a standard specification supported by the included micro USB cable. The automatic chip control and high temperature protection function add a layer of safety during use and charging.

Reuse and Low Maintenance

Because the hand warmer is rechargeable, it can be used repeatedly after each full charge. The flame-retardant ABS and aluminium alloy construction can be wiped clean with a soft dry cloth when needed. The flannel bag helps protect the surface from dust and scratches during storage. There are no replacement parts mentioned in the source data, and care should be limited to keeping the device dry and using the supplied cable for charging. The 5000mAh battery capacity is fixed and not user-replaceable based on the available information.

Why Choose This Product

This 2-in-1 hand warmer stands out for its double-sided heating, 52°C target temperature, and 5000mAh power bank function. It reaches warmth in about 30 seconds to 1 minute and runs for approximately 3.5 to 4.5 hours at 20°C after a full charge. The 69 x 74 x 34mm size makes it pocket-friendly, and the package includes the power supply, a USB cable, and a flannel bag. Colour choices are Chie Purple, Fan green, Full red, and You Fan.
