EASYLONGER vs. the Alternatives
Purpose-built for CPAP like the official batteries — at a fraction of the cost per watt-hour, and far quieter than a generic power station.
| Feature | EASYLONGER | Medistrom Pilot-24 Lite | Generic Power Station |
|---|---|---|---|
| Price per watt-hour | from $0.80 / Wh | ~$3.57 / Wh | ~$0.50-1.00 / Wh |
| Capacity options | 99.9 - 297.6 Wh | 95 Wh only | 200 - 1,000+ Wh |
| Built for CPAP | Yes | Yes | No |
| CPAP cables included | Yes — ResMed, Philips, BMC | Some — extra kits needed | None |
| Direct DC to your CPAP | Yes — no inverter loss | Yes | No — loses 15-20% |
| Adjustable voltage | Yes — 12 / 19 / 24V | No — fixed 24V | Varies |
| Operating noise | Silent — 0 dB | Silent | Fans / hum |
| Charges phones & laptops | Yes — USB up to 100W | Phones only | Yes |
| Warranty | 2 years | 1 year | 1-2 years |
Medistrom price from cpap.com ($339 ÷ 95Wh). Power-station figures are typical for consumer models. Running a CPAP on direct DC instead of an AC inverter delivers roughly 15-20% more runtime from the same battery.

What CPAP Users Say
Trusted by thousands of travelers and home sleepers across the U.S.
★★★★★
Charged it up and gave it a test run with my ResMed AirSense 10. I did NOT turn off the humidity or the hose heater, and it lasted all night. Exactly what we needed.
★★★★★
Worked great on my last long-haul flight when the outlet failed. Lasted a solid 6.5 hours on my ResMed 11 with the humidifier set at 4. Best low-cost CPAP battery.
★★★★★
Finally I can go hammock camping again now that I'm on a CPAP machine. The ES960 is a great size for an overnight camp — wish I'd bought one years ago.
