Introduction

Portable vacuum sealers are rapidly growing in popularity across household, outdoor, travel, and small commercial food-preservation markets. As customers prefer cordless, lightweight, and high-suction products, manufacturers are moving toward lithium battery-powered systems.

The performance of a vacuum sealer—suction power, sealing strength, motor stability, and cycles per charge—is highly dependent on the battery’s capabilities. Traditional alkaline or NiMH batteries often underperform in peak power output and lifespan.

PKNERGY provides advanced lithium-ion and lithium polymer battery solutions tailored for portable vacuum sealers, supporting full OEM/ODM integration.

Application Background

1. High Pulse Discharge Capability

Vacuum sealers require strong instantaneous current during suction and heating cycles. Lithium batteries must reliably deliver 5C–10C pulse discharge without voltage sag.

2. Long Runtime & Fast Recharging

Consumers expect 20–40 sealing cycles per charge. This requires high-density lithium cells with stable output.

3. Compact Integration

Portable sealers are small, handheld devices. Battery packs must be compact, lightweight, and properly thermally managed for long sealing sessions.

4. Safety & Compliance

Vacuum sealers use heating elements. Batteries must withstand heat, vibration, and repeated charging while meeting global certifications (UN38.3, IEC62133, CE, PSE).

Key Technical Requirements

• Stable high-current discharge for suction motors
• 20–40 sealing cycles per charge
• Compact pack design for narrow housing
• Thermal cutoff protection during heating
