Product Details
Two Removable Clothing Fans
The kit includes two brushless fans with removable outer housings and side retention structures. Each fan measures approximately 106 mm in outer diameter and 38 mm in height, with a nominal 90 mm installation opening.
77Wh Rechargeable Power Bank
The supplied battery has a labelled energy rating of 77Wh. Its 20,000mAh label capacity uses a 3.85V equivalent basis. Type-C, USB-A and DC interfaces provide the output profiles listed below.
Fan and Connection Accessories
The standard bundle includes the two fans, one fan connection cable, one rechargeable power bank and one charging cable. A matched kit lets buyers evaluate the fan and power components together.

Garment Integration
The HVJ-T50 is intended for compatible fan workwear and personal ventilation garments. Before selecting it for a jacket or vest, check the installation openings, fabric support, fan retention, cable routing and battery-pocket dimensions.
Provide garment drawings or sample details when requesting integration support. The kit supplies airflow ventilation; it is not presented as refrigerated air conditioning or protective equipment against heat exposure.
Wholesale & Project Enquiries
For a wholesale quotation, include model HVJ-T50, estimated quantity, destination and the intended garment application. Add your target delivery date and any sample requirements.
If your project requires branding, packaging changes or another configuration, include your brief for review. Feasibility, minimum quantities, costs and delivery timing require confirmation for the specific request.
For battery transport or market-entry documentation, state the destination and required documents. The supplier reports availability of battery MSDS and UN38.3 documents, cell CB documentation and fan PSE documentation; the underlying files and their applicability to the quoted configuration require review before confirmation. Packaging markings alone are not treated as verified CE or RoHS documentation.

Buyer Questions
What is included in the HVJ-T50 kit?
The standard bundle includes two clothing fans, one fan connection cable, one 77Wh rechargeable power bank and one charging cable, with kraft box packaging.
What fan voltage does the current kit use?
The current bundle fan labels show DC 12V. Factory performance data covers fan operating points at 8V, 10V and 12V.
How should the battery capacity be understood?
The battery is labelled 77Wh and 20,000mAh at a 3.85V equivalent basis. The 20,000mAh figure should be read together with that voltage basis, rather than as capacity at a DC output voltage.
How long does the kit operate?
Stated working time is approximately 8.5–16 hours with the current 77Wh battery configuration. Runtime varies with operating conditions; a separate duration for each operating level has not been supplied.
How long does charging take?
The battery specification lists 4.5–6 hours, typically 5 hours, under its stated QC3.0 / PD adapter test conditions. Charging time depends on the compatible adapter and operating conditions.
Will the fans fit any cooling jacket?
Fit requires a garment-specific check. The fan has a nominal 90 mm installation opening dimension; the garment opening, retention arrangement, fabric support and battery pocket should be reviewed together.
What should I include in a quotation request?
Include HVJ-T50, estimated quantity, destination, garment application, target delivery date and any sample, branding, packaging or documentation requirements.
