Buying Guide: Key Purchase Considerations
- CPAP compatibility: Verify that the back-up battery supports your CPAP model, including any humidifier or heated tube features you use.
- Capacity needs: Estimate nights of use per charge. For two-night trips, aim for 250–300Wh; for longer trips, 300Wh+ with multiple outputs is preferable.
- Output options: Look for a mix of AC, DC, and USB-C ports to power CPAP plus phones, tablets, or laptops.
- Weight and portability: If you’ll hike or travel by plane with your unit, lighter options (3–7 pounds) are more convenient; check airline restrictions for capacity limits.
- Recharging speed: Faster recharge can reduce downtime between uses; consider units with multiple input charging methods (AC, car, or solar where available).
- Safety and durability: Choose LiFePO4 or well-regulated Li-ion cells with protection against short circuits, overcharging, and high temperatures.
- Travel considerations: Some models exceed airline capacity limits; plan around TSA/airline rules to avoid delays or fees.
