Power & Cables (CPAP Machine Spare Part)

Keep your therapy safely powered with S-Med’s collection of genuine CPAP power supplies, adapters, and mains leads. Whether you need a replacement brick for your bedside unit, a specialized 12V/24V DC converter for travel, or an official battery cable, we stock authentic components engineered to protect your device. Trusted by NHS sleep clinics across the UK.

Genuine CPAP Power Supplies and Cables for Uninterrupted Sleep Therapy

A reliable, consistent electrical current is the lifeblood of your sleep apnoea therapy. Your CPAP or BiPAP machine is a highly sophisticated piece of medical equipment, packed with sensitive microprocessors and advanced pressure algorithms. Using generic, third-party power adapters can expose your device to unstable voltage, which risks overheating the internal motor or frying the motherboard. Investing in genuine manufacturer power supplies and cables is the only way to safeguard your machine, maintain your warranty, and guarantee uninterrupted therapy.

Over time, power cords can experience internal wire fraying from being packed for travel, stepped on, or tightly bent behind the bedside table. At S-Med, we provide a complete inventory of official replacement power components to get your machine back up and running instantly. Our collection covers all major device models—including the ResMed AirSense series and Löwenstein Prisma platforms—and features:

  • AC Power Supply Bricks & Mains Leads: Standard 90W and 60W original replacements to keep your primary bedside setup running securely.
  • 12V / 24V DC Converters: Specialized car, caravan, and boat adapters that allow you to safely run your machine off a vehicle cigarette lighter or leisure battery without draining power inefficiently.
  • Travel Battery Cables: Dedicated adapter cords required to hook up portable travel machines to airline-approved external batteries.

With over 23 years of clinical authority supplying NHS Trusts and private sleep specialists throughout the United Kingdom, S-Med ensures you always receive authentic, hospital-grade parts. Don't risk downtime on your treatment; enjoy fast, tracked UK delivery and expert after-sales support from our team of dedicated sleep physiologists to help you match the exact power rating your device requires.
