Portable Mini Air Extractors – Market and Application Background

Portable mini air extractors are increasingly used in compact kitchens, food trucks, outdoor cooking, and DIY home setups. Users prefer cordless and lightweight devices capable of removing smoke and odor efficiently.

The battery plays a decisive role in suction strength, motor stability, runtime, and portability. Traditional batteries such as NiMH or alkaline often fail to deliver adequate continuous current for strong smoke extraction.

PKNERGY provides custom Li-ion and LiPo battery solutions specifically engineered for portable mini air extractors.

Key Technical Requirements of Portable Air Extractors

1. High Current & Instant Power

Smoke extraction demands instantaneous high currents. Lithium batteries must supply stable 5C–10C pulse discharge to maintain strong suction without voltage drops.

2. Long Runtime & Fast Charging

Users expect 20–60 minutes of continuous operation. High-energy lithium cells allow long runtime with fast USB-C or DC charging.

3. Compact & Lightweight Design

• Small form factor for portable housings
• Lightweight for handheld usage
• Efficient heat dissipation during extended operation

4. Safety & Certifications

Operation near hot cooking surfaces demands safety protection including over-charge, over-discharge, short-circuit protection, and compliance with UN38.3, IEC62133, UL, CE.
