Last updated September 24, 2026. EcoFlow figures from EcoFlow’s DELTA product materials. Renogy figures from Renogy’s PHOENIX 500 materials (495 Wh / 800 W class). Not a Boom lab. Renogy has no Boom Awin mid—links are manufacturer or Amazon only.
“Renogy 500” in older shopping copy usually means the Renogy PHOENIX 500 (~495 Wh). Stacked against the original EcoFlow DELTA (~1,260 Wh / 1,800 W), this is a lightweight camping box vs a heavier mid-home backup station.
Quick decision
- Pick PHOENIX 500 for ~16–17 lb class portability and ~800 W continuous when loads stay light.
- Pick EcoFlow DELTA for roughly 2.5× the watt-hours and more than double continuous AC watts.

Who should buy / who should skip
Buy Renogy PHOENIX 500 if…
- Camping / tailgate loads stay under 800 W and ~0.5 kWh is enough overnight.
- You already use Renogy solar kits and want brand continuity (still verify VOC/amps).
Skip Renogy 500 if…
- Fridge + tools + multi-day outage are the job—DELTA’s Wh and watts are the honest fit.
Buy EcoFlow DELTA if…
- Home essentials and higher continuous AC matter more than shaving 14 lb.
Skip EcoFlow DELTA if…
- You only need phone/laptop/camera power—DELTA is overkill and over-heavy.
Failure modes
- Name confusion: “500” is marketing capacity class, not 500 Wh exact—PHOENIX 500 is 495 Wh.
- App / expand claims: older Pro copy mentioned iStack / DC HOME—only trust what Renogy still prints on the live page for your SKU.
- Inverter ceiling: an 800 W Renogy will not start many space heaters or compressors that a 1,800 W DELTA might.
