Why Choose the Volpower S11 72W Power Adapter?

Complete Two-Piece Kit
Unlike basic chargers, the S11 kit includes both the main adapter and a 50cm extension cable. The main adapter features 20AWG thick copper wire, while the extension uses even thicker 18AWG copper with TPE casing – giving you superior power delivery and extra reach.

Universal AC Input
Works with 100-240V 50/60Hz power outlets worldwide. Perfect for international travel – just bring a plug adapter for your destination.

Perfect Fit for ResMed S11 Series
Engineered specifically for ResMed AirSense 11 and AirMini machines. Outputs exactly 24V at 3A (72W) – the precise power requirements for reliable CPAP operation.

Thick Copper Wire Construction
20AWG wire in the main adapter and 18AWG wire in the extension cable minimize voltage drop over distance. Your CPAP receives stable, consistent power even when placed far from the wall outlet.

Dual Cable Setup for Flexibility
The combined 170cm total length (120cm + 50cm) allows you to position your CPAP machine exactly where you want it – bedside table, nightstand, or floor – without straining the connection.

TPE and ABS Durable Materials
The extension cable features a soft yet strong TPE casing that resists cracking and bending. The adapter housing uses impact-resistant ABS for long-term reliability.

Multiple Safety Protections
Six built-in circuit protections (OVP, UVP, OCP, OTP, SCP) give you peace of mind every night. The adapter automatically shuts down if abnormal voltage, current, or temperature is detected.
