Best CPAP Travel Battery: Jackery 500 vs Goal Zero Yeti 500X vs EcoFlow River 2 Pro

May 1, 2026

The short answer

These three are the realistic candidates if you want a sub-20-lb AC power station that runs a CPAP for at least one comfortable night.

• EcoFlow River 2 Pro is the technical winner: LFP chemistry, fast charging, the only one of the three that supports a heated humidifier overnight. Best long-term value.
• Jackery Explorer 500 wins on price and weight: lightest at 13.3 lbs, regularly $299-349 on sale, easiest to find at retail.
• Goal Zero Yeti 500X wins on niche ergonomics: USB-C Power Delivery for laptops, the most rugged build, strong outdoor-brand pedigree.

If you cycle weekly or want humidifier runtime, stop reading and pick the River 2 Pro. If you don’t, the others are legitimate choices for specific reasons below.

How each unit positions itself

EcoFlow River 2 Pro — the modern technical winner

768 Wh of LFP capacity (3000+ cycles), 800W continuous AC with 1600W X-Boost, 17 lbs, and a ~70-minute full recharge from wall. The only one of the three that handles a heated humidifier for a single night without falling short on capacity, and the only one whose battery chemistry supports nightly cycling for years without degradation.

The trade-off: 17 lbs is the heaviest of the three, and EcoFlow leans on its app for advanced features. If you want a “no phone, no fuss” battery, this is the most app-dependent of the three.

Jackery Explorer 500 — the price and weight winner

518 Wh NMC, 500W continuous AC, 13.3 lbs, ~7.5 hours to full from wall. The lightest AC unit in this guide. Same chemistry profile as the Yeti 500X (NMC, ~500 cycles) and roughly the same capacity, but lighter, slightly cheaper at MSRP, and from a brand with the deepest retail presence.

The trade-off: NMC chemistry means it’s not the right choice for nightly use over multiple years. No humidifier runtime — capacity is the bottleneck. Slow recharge.

Goal Zero Yeti 500X — the ergonomic specialist

505 Wh NMC, 300W continuous AC, 12.9 lbs, USB-C Power Delivery at 60W. Rugged build, established outdoor-pro reputation, and the strongest USB-C output of the three. The only unit that gracefully handles “CPAP plus modern laptop plus phone” without dragging out a separate charger brick.

The trade-off: 300W AC ceiling is the lowest of the three, capacity ties the Jackery 500 (no humidifier), and the price-per-Wh is the worst in the guide ($1.18/Wh at MSRP). NMC chemistry, like the Jackery 500.

Side-by-side specs that matter

Best in each row marked in bold. The River 2 Pro takes the most categories — capacity, chemistry, AC ceiling, recharge speed, $/Wh, and humidifier support. The Yeti wins weight and USB-C PD wattage. The Jackery wins nothing outright but stays competitive on price.

Final winner by use case

How to think about the decision

If your trip pattern is occasional car-camping, no humidifier, 1-2 trips per year, all three work and Jackery’s sale price wins on cost. NMC vs LFP doesn’t matter at this usage level.

If you’ll cycle the battery weekly or more (vans, frequent campers, regular outage areas), the River 2 Pro is the only one whose chemistry survives that pattern without significant capacity loss within 4-5 years.

If you need humidifier runtime even occasionally, only the River 2 Pro has the capacity and inverter to deliver it. The Jackery 500 and Yeti 500X are CPAP-only batteries by capacity, full stop.

If you fly with your CPAP, none of these three are the answer — they all exceed the 100Wh airline carry-on limit. See the Medistrom Pilot-24 Lite for the only flyable category.
