1. The Shift Toward Portable Heating Solutions

Traditional plug-in heating pads limit user mobility, requiring access to AC power. Modern consumers want products that allow movement—
whether they are working, traveling, or resting at home. Waist heating pads powered by lithium-ion batteries provide continuous heat
while allowing full freedom of motion. This convenience has significantly increased the popularity of battery-powered heating pads
in global markets.

2. Why Lithium-Ion Batteries Are the Ideal Power Source

Waist heating pads typically operate for 1–6 hours depending on heating levels, making energy efficiency a top priority.
Lithium-ion batteries offer several advantages:

• High energy density enabling slim and lightweight product designs
• Stable voltage output that ensures consistent heating temperature
• Long cycle life supporting long-term daily use
• Faster charging compared to older battery chemistries
• Compact size that fits easily into wearable heating belts

Most waist heating pads today rely on 3.7 V or 7.4 V power systems, often created using 1S or 2S Li-ion battery packs.
PKNERGY provides customized solutions from 2000 mAh to 10000 mAh to achieve the required runtime and heat levels.

For designs that prioritize maximum safety and cycle life, we can also provide

custom LiFePO4 battery options for wearable or near-body applications.

3. Safety Considerations for Wearable Heating Products

Because waist heating pads are worn directly on the body, safety requirements are extremely strict.
PKNERGY integrates advanced PCM/BMS systems in every battery pack to ensure user protection during operation.
Key features include:

• Overcharge and over-discharge protection
• Short circuit and overcurrent protection
• Temperature control and monitoring
• Stable discharge performance during peak load

All PKNERGY battery packs can be certified under UN38.3 and IEC 62133 as required for medical or consumer export markets.

4. Engineering Support for Brand Manufacturers

The design of waist heating pads requires close coordination between heating elements, control circuits, and power systems.
PKNERGY offers complete customization support to ensure ideal system integration, including:

• Slim battery geometries to improve comfort
• Curved battery casings for ergonomic fit
• Reinforced enclosures for impact safety
• USB-C or magnetic charging module integration
• Customized wiring harnesses and connectors

Our engineers collaborate with customers from concept to final mass production, ensuring that the battery pack fits seamlessly
into the heating pad structure.

5. Market Trends & User Expectations

Consumers increasingly demand more advanced heating pads with adjustable temperature levels, fast heating response,
and longer operating times. Some products integrate vibration massage, automatic temperature balance, or mobile app control.
All these features rely heavily on stable power supply.

Lithium-ion technology provides the efficiency and flexibility that modern heating pads require to meet these expectations.
