Comparison

EcoFlow Delta 3 Plus vs Jackery Explorer 1000 v2

Delta 3 Plus vs Jackery Explorer 1000 v2: two 1 kWh LiFePO4 stations compared on output, charging, solar, expansion, weight and warranty, with a clear pick.

Pick the EcoFlow Delta 3 Plus for more output, more solar and room to grow to 5 kWh; pick the Jackery Explorer 1000 v2 if a lighter station that's easy to carry matters most. Both hold 1,024 Wh of LiFePO4.

The short answer: Delta 3 Plus vs Explorer 1000 v2

Same battery, different priorities

  • Choose the EcoFlow Delta 3 Plus for home backup, off-grid solar or anything you may want to grow later. It has more output, twice the AC outlets, 2.5 times the solar input and expands to 5 kWh.
  • Choose the Jackery Explorer 1000 v2 if you'll carry it often and 1 kWh at 1,500 W covers your needs: camping, tailgates, a CPAP or a home office.

  • Same: capacity (1,024 Wh), LiFePO4 chemistry, about 10 ms UPS switchover, 4,000 rated cycles.
  • Delta 3 Plus wins: output, AC outlets (6 vs 3), solar input, expansion, cycle rating (to 80% vs 70%), warranty.
  • Explorer 1000 v2 wins: weight, and a slightly faster top wall-charge time.

New to these numbers? Watts vs watt-hours explains which is which.

Charging speed

Both under an hour, with a catch

The Explorer 1000 v2 fills in about 50 minutes with Emergency Super Charge, which you switch on in the Jackery app. In its standard mode a full charge takes about 1.6 hours.

Both refill from the wall in under an hour.

The Delta 3 Plus takes 1,500 W for a full charge in about 56 minutes, with no setting to change. It also accepts 800 W through EcoFlow's alternator charger and pairs with EcoFlow's Smart Generator.

Either refills during a short window of grid power. Day to day, the Delta 3 Plus is faster because its top speed is the default.

Solar input

The Delta 3 Plus takes far more

The Delta 3 Plus accepts 1,000 W of solar across two 500 W inputs (11–60 V each), for a full charge in about 70 minutes with enough panels. The Explorer 1000 v2 takes 400 W across two inputs (12–60 V).

The Delta 3 Plus takes 1,000 W of solar; the Explorer 1000 v2 takes 400 W.

With 400 W of panels, the Explorer needs about 3.4 hours of full sun to fill. If solar is your main way to recharge, the Delta 3 Plus gets much more out of a sunny spell. See what size solar panel you need, or what a solar generator bundle includes.

Output and outlets

More watts and twice the outlets on the EcoFlow

The Delta 3 Plus delivers 1,800 W continuous (3,600 W surge) across 6 AC outlets. Its X-Boost runs some simple heating appliances, like kettles, at up to 2,200 W by lowering their power; that isn't extra continuous output.

Six AC outlets and 1,800 W against three outlets and 1,500 W.

The Explorer 1000 v2 delivers 1,500 W continuous (3,000 W surge) across 3 AC outlets. That covers a fridge, a coffee maker or a microwave on its own, with less headroom.

Neither runs two big kitchen appliances together, or anything on 240 V.

Runtime

Identical batteries, identical runtimes

Estimated runtimes on either station

  • CPAP, no humidifier, DC cord27 h
  • CPAP with humidifier, AC11 h
  • Fridge + Wi-Fi router11 h
1,024 Wh at 85% efficiency for AC and 92% for DC, plus 10 W inverter idle draw when AC is on. CPAP 35 W / 70 W; fridge 60 W average; router 12 W on DC.

With the same 1,024 Wh battery, both run a fridge and router for about 11 hours.

With the same 1,024 Wh, runtime won't decide this. A fridge and router through the night is realistic on either. Try your own devices in the runtime calculator.

Expandability

Only one can grow

The Delta 3 Plus grows from 1 kWh to 5 kWh with EcoFlow extra batteries, enough for multi-day home backup.

Only the Delta 3 Plus can add batteries, up to 5 kWh.

The Explorer 1000 v2 can't add batteries. For more capacity you'd need a bigger Jackery, such as the HomePower 2000 Plus v2. The Explorer 1000 Plus adds a little more (1,264 Wh), but its expansion battery is no longer available.

Backup (UPS), noise and app

Close on backup; only EcoFlow publishes a noise figure

Both switch to battery in about 10 ms, fast enough for most computers, routers and CPAP machines.

EcoFlow rates the Delta 3 Plus at 30 dB below 600 W. Jackery doesn't publish a noise figure for the Explorer 1000 v2. Both get louder when charging fast.

Both have phone apps (Wi-Fi and Bluetooth) for monitoring and charge settings; the Jackery app is also where you turn on Emergency Super Charge.

Weight, battery life and warranty

Lighter Jackery, longer-rated EcoFlow

  • Weight: the Explorer 1000 v2 is 23.8 lb; the Delta 3 Plus is 27.6 lb, about 4 lb heavier.
  • Battery life: both are rated for 4,000 cycles, but to different endpoints: the Delta 3 Plus to 80% capacity, the Explorer 1000 v2 to 70%. See LiFePO4 vs lithium-ion.
  • Warranty: the Delta 3 Plus has 5 years. The Explorer 1000 v2 has 3 years, plus 2 more when you register it with Jackery.
