How Heating Batteries Work
Heating batteries deliver constant DC voltage to resistive heating elements embedded in apparel fabric. Unlike standard USB power banks, they are optimized for sustained high-current discharge at low temperatures.
"The global heated clothing market is projected to grow from $480 million in 2025 to $830 million by 2031 at a 9.56% CAGR, while the battery-heated warm jacket segment specifically is forecast to reach $451 million by 2031 at a 12% CAGR. The U.S. ski industry alone recorded 60.4 million visits in the 2023-2024 season, with winter sports participation exceeding 30 million participants. The key differentiator for brands is the battery: runtime at sub-zero temperatures, connector reliability over 500+ charge cycles, and multi-market safety certifications — PSE (Japan), UL (US), UN38.3 (global air transport), and CE (EU) — are what separate premium heated apparel from commodity imports."

5V vs. 7.4V vs. 12V: Voltage Guide for Heated Clothing
What voltage battery do heated jackets use? The answer depends on your product's heat output requirements. Most heated jackets and vests use 7.4V (2S lithium cells), but 5V and 12V serve specific niches.
| Parameter | 5V USB Entry-Level |
7.4V DC Most Popular |
12V DC High Power |
|---|---|---|---|
| Typical Applications | Scarves, heated pillows, light wraps | Jackets, vests, gloves, socks | Motorcycle gear, industrial, heated blankets |
| Heat Output | 3-8W (low warmth) | 8-25W (moderate-high) | 20-60W (intense heat) |
| Market Share | ~15% | ~70% | ~15% |
| Typical Capacity | 5000-10000mAh | 2600-14400mAh | 5000-20000mAh |
| Battery Size | Standard power bank | Compact (fits jacket pocket) | Larger (belt/pack mounted) |
| Connector | USB-C / Micro-USB | DC barrel / Pogo pin / Custom | DC barrel / Custom |
| WOWOHCOOL Models | Available on request | 5 standard models + ODM | ODM custom |
How Long Does a Heated Jacket Battery Last?
Runtime depends on battery capacity (Wh) and heat level selected. Formula: Runtime (hours) = Battery Energy (Wh) ÷ Power Draw (W). Here's what to expect from common configurations:
| Battery (7.4V) | Energy (Wh) | Low (5W) | Medium (8W) | High (12W) |
|---|---|---|---|---|
| 2600mAh | 19.2 Wh | ~3.8 hrs | ~2.4 hrs | ~1.6 hrs |
| 5000mAh | 37 Wh | ~7.4 hrs | ~4.6 hrs | ~3.1 hrs |
| 7500mAh | 55.5 Wh | ~11 hrs | ~6.9 hrs | ~4.6 hrs |
| 10000mAh | 74 Wh | ~14.8 hrs | ~9.3 hrs | ~6.2 hrs |
| 14400mAh | 106.6 Wh | ~21 hrs | ~13.3 hrs | ~8.9 hrs |
Actual runtime varies by heating zone count, ambient temperature, and garment insulation. Low/Med/High power draw based on typical 3-zone heated jacket. Contact us for runtime calculations specific to your product design.
