Medistrom Pilot Flex CPAP Battery

The Pilot Flex keeps your CPAP running where there's no outlet, or when the power goes out at home. It suits campers, cottagers and frequent flyers, and anyone in an area where storms knock out the grid, who'd rather not skip therapy for a night.

It's thin and light enough to slip into a backpack, and it charges from the power adapter you already own at home. Pair it with the cable kit for your machine, and the same battery covers a weekend away and a blackout back home.

Key features:

• Carry-on capacity: Sized just under the threshold where airlines require approval for spare batteries, so it can fly in the cabin with you.
• Backup between wall and machine: Set up in the middle of your power chain, it stays charged and keeps therapy going if the electricity drops.
• Works across brands: With the matching cable kit, it powers ResMed AirSense and AirMini machines, Philips DreamStations and several other models.
• Charges your phone too: Its USB ports top up a phone or tablet, though the USB-C port switches off while a CPAP is connected.
• Four-light gauge: A row of green lights shows roughly how much charge is left, so you know before bed whether it'll last the night.
• Licensed in Canada: It's listed on a Class II Health Canada medical device licence held by the Ontario company behind Medistrom.

If you want therapy that keeps going on a canoe trip, a long-haul flight or a night when the power fails, the Pilot Flex was made for it. For the longest run between charges, plan on switching off the humidifier and heated tube.
