About Medistrom Pilot Flex CPAP Battery — 98Wh
Medistrom Pilot Flex CPAP battery — a portable power supply with 98Wh capacity and automatic voltage switching for your CPAP machine on trips, while camping and during power cuts. The Pilot Flex weighs only 544 g and measures 16.7 × 7.5 × 2 cm, which makes it one of the most compact CPAP batteries available.
Automatic voltage switching and backup power
The battery switches automatically between 12V and 24V depending on which machine you connect, so you do not have to work out what voltage your CPAP machine needs. The Pilot Flex also works as backup power at home — if the mains fails during the night, the battery takes over without interruption so your therapy continues.
Compatible CPAP machines
The Pilot Flex works with most popular CPAP machines. A cable for the ResMed AirMini is included in the package. For other machines you need an additional cable kit:
- ResMed AirMini — cable included in the package
- ResMed AirSense 11 (additional cable kit)
- ResMed AirSense 10 (additional cable kit)
- Philips Respironics DreamStation 1 and 2 (additional cable kit)
- Philips Respironics DreamStation Go (additional cable kit)
- Löwenstein Medical prismaSMART (additional cable kit)
Benefits of this portable CPAP power supply
- 98Wh capacity, which gives up to 16 hours of operation
- Weighs only 544 g in a compact aluminium casing, so it travels easily
- FAA and TSA approved (98Wh, under the 100Wh limit) — you can take it as hand luggage
- Automatic voltage switching between 12V and 24V for all compatible CPAP machines
- USB-A and USB-C ports so you can also charge a phone, tablet or other devices
- You can link several Pilot Flex batteries together for even longer running time
- Built-in LED torch and a 4-step charge level indicator
You charge the battery with your CPAP machine’s existing power adapter. With an original ResMed or Philips AC adapter a full charge takes 2–3 hours. You can also use the short AirMini cable, which then charges in 7–9 hours. The 4-step indicator means you always see how much power is left.
The USB port on the battery is an output for charging other devices such as mobile phones or tablets.
Who is this for?
The Pilot Flex suits you who travel and want the reassurance that your battery lasts the whole night away from home. It also works well when camping, in a motorhome or as backup power at home during a power cut. Because of the FAA approval you can fly with it in your hand luggage.
The package contains the Medistrom Pilot Flex battery, a cable and a short charging adapter for the ResMed AirMini, plus a manual and quick guide in English, French, German and Spanish. For other CPAP machines you also need to order the right cable kit, listed above. See more CPAP batteries in our range, or read about sleep apnoea on NHS.uk.
