Product Overview

The Z20 graphene heated hand warmer is a compact rechargeable warming device with double-sided graphene heating and a built-in 5000mAh battery.

The product provides three selectable heating levels through a single control button. Long pressing switches the unit on or off, while short pressing changes the heating level. Product materials indicate rapid heating within several seconds, with the heating surface gradually reaching the selected operating temperature.

A 5000mAh battery supports cordless use and can also provide emergency charging for compatible mobile devices. The product uses a Type-C charging interface and includes charging and discharging protection.

The housing combines an anodized aluminum-alloy outer shell with an ABS flame-retardant inner structure. With a compact size of 110 × 73 mm and a weight of approximately 130 g, the Z20 is easy to carry in a pocket, bag or luggage. OEM and ODM requirements such as branding, packaging and exterior color can be reviewed according to project specifications.
