Current 1 kWh Models: EcoFlow DELTA 3 vs DELTA 3 Classic vs DELTA 3 Plus vs OUPES Mega 1 vs BLUETTI Elite 100 mini

Five current-generation 1 kWh LiFePO4 stations sold on Amazon. Four share roughly the same 1,024 Wh pack, so they separate on output (700–2,000 W), solar input (350–1,000 W), charging speed, expansion, and footprint (10.7–12.6 kg).

Verdict

The three EcoFlow DELTA 3 models share a 1,024 Wh LFP pack, 1,800 W continuous with a 3,600 W surge, six AC outlets and a sub-10 ms UPS, and differ on extras. The DELTA 3 Plus is the most capable: 1,000 W of solar across two inputs, 140 W USB-C, 4,000 cycles to 80% and expansion to 5 kWh. The DELTA 3 has an official 56-minute full charge, 500 W solar and the same expansion. The DELTA 3 Classic drops expansion and some low-voltage ports, charges at 1,400 W (80% in about 45 minutes) and publishes no cycle rating, so it suits buyers who will never add a battery. The OUPES Mega 1 has the strongest inverter here, 2,000 W continuous and 4,500 W surge, with expansion to 5,120 Wh and a claimed 36-minute 0 to 80% charge, but its specs come only from its Amazon listing and it has four AC outlets. The BLUETTI Elite 100 mini is the small-footprint pick: 10.7 kg in an upright case with three AC outlets and 140 W USB-C, but only 700 W continuous and 350 W solar.

Strengths and weaknesses

EcoFlow DELTA 3

Strengths

  • Official 56-minute full recharge — fastest in this index's 1 kWh class
  • 4,000-cycle LFP rating at the 80% threshold
  • Documented standby UPS with 10 ms transfer (not just marketing)
  • Six AC outlets with 3,600 W surge
  • Cross-compatible with four extra-battery models

Weaknesses

  • X-Boost figure conflicts between the US page (2,200 W) and manual 120 V table (2,600 W)
  • Native car charging is only ~96 W (the '800 W in 1.3 h' page claim requires the separately sold Alternator Charger)
  • DC5521 ports lack a stated wattage
  • Crowded DELTA 3 family naming (Plus/Classic/1500/Max/Ultra) invites confusion

EcoFlow DELTA 3 Classic

Strengths

  • Same 1,800 W / 3,600 W surge output as the DELTA 3 in the same 1,024 Wh LFP size
  • Sub-10 ms UPS switchover stated by EcoFlow
  • 500 W solar input
  • App control with scheduled charging

Weaknesses

  • Not expandable: no extra-battery support at all
  • Fewer low-voltage ports than the DELTA 3 (one USB-A, no car outlet or DC5521 listed)
  • EcoFlow publishes no cycle-life figure for it, only a 10-year lifespan estimate
  • No full 0 to 100% AC recharge time published, only 0 to 80%

EcoFlow DELTA 3 Plus

Strengths

  • 1,000 W of solar input over two ports
  • 56-minute full AC charge at 1,500 W
  • 140 W USB-C ports
  • 4,000 cycles to 80% and a 5-year warranty
  • Takes four families of EcoFlow extra batteries

Weaknesses

  • Same 1,800 W continuous ceiling as the cheaper DELTA 3
  • AC outlet types not stated
  • The 56-minute figure comes from a feature line, not the spec table
  • Waveform not stated in the specifications read

OUPES Mega 1

Strengths

  • 2,000 W continuous is high for a 1 kWh unit
  • Expandable to 5,120 Wh with two B2 batteries
  • Claimed 36-minute 0 to 80% AC charge
  • Two 100 W USB-C ports

Weaknesses

  • Specs come only from the Amazon listing; no manufacturer documentation was checked
  • AC outlet count rests on a single ambiguous listing row
  • No full AC recharge time, solar input wattage or solar voltage range stated
  • UPS claim (<20 ms) is marketing only, so recorded as unknown

BLUETTI Elite 100 mini

Strengths

  • 1 kWh in an unusually small upright footprint
  • Under 10 W self-consumption stated
  • 700 W AC charging
  • Built-in LED light with SOS mode

Weaknesses

  • 700 W continuous is low for 1 kWh
  • No surge rating or cycle-life threshold published, by the listing or BLUETTI's page
  • Not stated as expandable
  • 4-year warranty on Amazon; BLUETTI's page does not state a term

Sources and evidence

  • Created 2026-10-31 for current 1 kWh models sold on Amazon. The DELTA 3 values come from EcoFlow's official sources; the DELTA 3 Classic and DELTA 3 Plus combine EcoFlow's pages with their Amazon listings; the OUPES Mega 1 and BLUETTI Elite 100 mini come mainly from their Amazon listings (the Elite 100 mini is corroborated by BLUETTI's page).
  • Boost modes (X-Boost, Power Lifting) are never counted as continuous or surge output, and partial-charge claims are never shown as full-recharge times.
  • The older 1 kWh comparison (DELTA 2, AC180, Explorer 1000 v2, SOLIX C1000, E1000LFP) remains at /comparisons/1kwh-class-power-stations/.
  • Per-field raw claims, source URLs and recorded conflicts are on each linked product page.
