With a slim body, lightweight construction and dedicated DC output, the FA-026 is well suited to heated apparel brands, outdoor equipment suppliers, workwear companies, distributors and private-label buyers looking for a small battery pack that can be integrated into wearable products. Explore our heated clothing battery pack solutions for heated jackets, vests and cooling garments.
The FA-026 uses a 4000mAh battery capacity and supports USB-C input at 5V/2A up to 10W for convenient recharging. Its dedicated DC output provides 5V/2A up to 10W, making it suitable for compatible electrically heated garments, cooling apparel and other wearable applications that require a compact external battery source. Because heating systems and connectors can vary by garment, buyers should confirm the required voltage, connector specification and product compatibility before mass production.
A key advantage of the FA-026 is portability. Measuring just 49 × 15 × 79 mm and weighing approximately 79 g, it is designed for use where size and weight matter. The compact plastic housing can fit into suitable battery pockets without adding excessive bulk, while the LED indicator provides a simple visual reference for battery status.
