What We Like

  • Fastest AC recharge in its class (0–100% in ~80 min)
  • Great balance of power and portability
  • Expandable to 3 kWh with extra batteries
  • LiFePO4 pack rated for 3,000+ cycles
  • Feature-rich app with charge-rate control
  • X-Boost stretches high-wattage devices beyond 1,800 W

What We Don't Like

  • Fan gets loud under heavy loads
  • Solar input limited to 500 W
  • Heavier than some competitors with similar capacity
  • No wireless charging pad

Portability

At 27 lbs the DELTA 2 is a genuine one-hand carry with its integrated handles and compact footprint — heavier than the Explorer 1000 v2, but still easy to move from closet to car to campsite.

Charging

X-Stream AC charging takes the pack from 0 to 80% in about 50 minutes and to full in roughly 80 — which changes how you use it: top up over lunch instead of planning around an overnight charge.

App experience

The EcoFlow app is among the deepest in the category: firmware updates, adjustable AC charge rates (slower charging extends battery life), and per-port monitoring over Wi-Fi or Bluetooth.

Solar pairing

With the full 500 W of solar input and decent sun, the pack refills in a bit over two hours of good conditions — enough to run a 12V fridge indefinitely on a camping loop.

The Verdict

The DELTA 2 is one of the most well-rounded 1 kWh power stations on the market. It leads its class in charging speed, the LiFePO4 chemistry means it will outlive older NMC rivals several times over, and the expansion battery option gives it room to grow that fixed-capacity competitors can't match.

Bottom line

If you want fast charging, durable chemistry, and expandability in a portable package, the DELTA 2 is tough to beat.
