If you rely on CPAP therapy but still enjoy the outdoors, having a portable power solution is key. When selecting a battery, consider crucial factors like capacity, weight, versatility, features, durability and warranty.
Look for a battery rated to fully charge your CPAP machine at least once, if not twice, before needing a recharge. This provides a safety buffer in case of unexpected higher power needs. Lithium-ion batteries tend to offer higher energy densities than heavy lead-acid options, packing more power into a compact size. Make sure to calculate your CPAP's daily power needs to ensure adequate runtimes.
Batteries with LiFePO4 chemistry, such as the EXP96PRO, are exceedingly safe compared to other lithium types like Lithium Ion. LiFePO4 batteries have thermal stability and will not catch fire even if punctured or overcharged. This peace of mind is important when camping in remote areas.
Weight & Size
Consider how you plan to camp - whether car camping where weight isn't a concern, or backpacking into remote areas. Heftier batteries may be acceptable for a vehicle but go as light as reasonably possible for hiking long distances with gear. Quality CPAP batteries range from under 2 pounds up to over 5 pounds depending on capacity. The EXP48PRO is an optimal size and weight for backpacking. Battery shape and included accessories also impact overall packability.
In addition to powering just your CPAP, look for a battery that allows simultaneous charging of other essential devices like phones, GPS units or headlamps via USB or AC ports. This provides flexibility. Some battery models also integrate solar charging capabilities, allowing you to recharge off-grid using sunlight for true independence on extended trips.
Choose a battery with an all-weather design proven to withstand dusty, wet, hot and cold outdoor conditions over multiple seasons. Lithium-ion chemistries maintain their charge better when not fully discharged between uses, versus lead-acid alternatives. Look for impact resistance and water-resistant casing ratings to feel confident about reliability in remote areas.
Quality batteries always include long warranty periods, commonly 2 years or more. This protects your investment and gives peace of mind that the manufacturer will stand behind their product, even replacing it if anything goes wrong during multi-day trips in remote locales far from home.
Doing thorough research upfront makes finding the ideal camping companion battery for keeping CPAP therapy uninterrupted under the stars achievable and hassle-free.
