A Rechargeable Neck Warmer with a Detachable Hand-Warming Module
The HONVENJA HVJ-NP01 combines a padded wearable neck wrap with a detachable hand-warmer module. Use the assembled product for neck warming, or remove the front warming module for handheld use.
Three selectable heating levels are provided for each warming mode. The neck-warming settings are 40°C, 45°C and 50°C, while the hand-warmer settings are 45°C, 50°C and 55°C.
The current configuration uses a rechargeable 5000mAh / 3.7 V / 18.5 Wh lithium-ion battery system with USB Type-C charging. The specifications, operating-time references and packing data below describe this HVJ-NP01 configuration.
Product Details
Two Practical Warming Modes
The removable front warming module allows the product to switch between wearable neck warming and handheld warming. The neck wrap has a soft padded contact surface, with heat distributed around the neck area from the central warming module.
Three Heating Levels for Each Mode
Physical buttons provide three selectable heating levels. Separate temperature ranges are specified for neck use and hand warming, allowing users to select a setting for the intended warming mode.
5000mAh Battery and Type-C Charging
The rechargeable battery system is rated at 3.7 V / 5000mAh / 18.5 Wh. Approximate charging time is 3.5 hours. Operating time varies with the warming mode, heating level and conditions of use.

Personal Warming and Product Evaluation
The HVJ-NP01 provides two formats for personal warming: a padded wrap worn around the neck and a detachable module held in the hands. Its dual-use structure gives buyers a rechargeable heating product to evaluate for seasonal retail, personal-comfort ranges and gifting projects.
When assessing a sample, review neck fit, contact comfort, button operation, module removal and the heating experience in both modes. Include your intended users and application when requesting samples so product suitability can be reviewed.
