EcoFlow River 2

Check Price — EcoFlow River 2What Matters for Best Portable Power Station for Emergency Backup
- Reliability and battery longevity during storage
- Capacity for overnight essential device operation
- AC output for medical devices (CPAP, refrigeration)
- Ease of setup — no technical knowledge required
- Regular self-discharge testing recommended
Emergency power backup has different priorities to camping or van life. You want reliability above all else, enough capacity to run essential devices for 12+ hours, and ideally an LFP battery that holds its charge well during long storage. The EcoFlow River 2 at ~$449 is the most practical emergency backup option for most Australian households — compact enough to store in a cupboard, powerful enough for phone and laptop charging, LED lighting, a fan, and importantly a CPAP machine through the night. For households with medical devices or refrigeration needs during blackouts, step up to the EcoFlow Delta 2 with its 1800W output and 1024Wh capacity.

Jackery Explorer 500
At a Glance
- Compact and lightweight at just 6.4kg
- 518Wh handles a weekend of device charging and lighting
- Simple LCD display is easy to read
- Multiple output ports — AC, DC, USB-A, USB-C

Frequently Asked Questions
+ How long does a CPAP machine run on a portable power station?
A CPAP machine typically draws 30–60W with a DC converter (lower than using the AC adapter). On a 256Wh EcoFlow River 2, expect 4–8 hours of CPAP use. On a 518Wh Jackery Explorer 500, expect 8–17 hours. For a full night's CPAP use, a 500Wh+ power station with a DC cable for your specific CPAP is the practical minimum.
+ How long can a portable power station be stored without losing charge?
LFP batteries (EcoFlow Delta 2, Bluetti AC60) self-discharge at 1–3% per month — a fully charged station stored for 6 months would still be at 80%+ charge. NMC batteries (Jackery, standard EcoFlow River 2) discharge slightly faster. For emergency backup that sits unused for months, choose LFP chemistry and store at 50–80% charge for optimal battery health.
