What owners report

Most praised
  • The fastest recharge in this size class, which matters when an outage warning comes late.
  • High output for a 1kWh unit, handling kitchen appliances that smaller stations cannot.
  • Compact for its output, fitting under a desk or beside a bed without fuss.
Common complaints
  • The fastest recharge mode requires the app, and owners who skip the app never see it.
  • No battery expansion, so owners who outgrow 1kWh must buy a larger unit instead.
  • Bundle variants with panels cause confusion at checkout about what is actually included.

What owners report

Most praised
  • The sheer number of ports suits a household that wants everything plugged in at once.
  • Recharge speed stands out for a 1kWh unit, cutting waiting time before the next trip.
  • Expansion support gives a clear upgrade path instead of replacing the whole unit later.
Common complaints
  • Bulkier than the older 1kWh models, so it is more of a garage unit than a carry-anywhere one.
  • The app is needed for some settings, which frustrates owners who prefer physical controls only.
  • Extra batteries add a lot of cost, so the headline expansion figure is not a cheap upgrade.

Our recommendation

Choose on the question of growth versus power. The Anker SOLIX C1000 Gen 2 gives the stronger 1kWh station today: 2000W output against 1800W, a 49-minute HyperFlash recharge, a 10 ms UPS switchover and a lighter 24.9 lb body. The EcoFlow DELTA 3 gives the station that grows: 13 outlets against 10, and expansion from 1024Wh to 5kWh that the Anker cannot match. If your load list is fixed and your appliances are demanding, take the Anker. If your backup needs may grow, or your household simply plugs in a lot at once, take the EcoFlow and budget for extra batteries later.

Output and UPS cover

The Anker outputs 2000W with a 3000W peak, the strongest 1kWh output here, and switches over in 10 ms as a UPS, so a router keeps running through a brief outage. The DELTA 3 outputs 1800W with X-Boost for higher-draw resistive appliances and offers no stated UPS switchover figure in this guide. For kitchen appliances and uninterrupted loads, the Anker is the stronger hand.

Outlets and expansion

The DELTA 3 offers 13 outlets against the Anker 10 ports, and it expands to 5kWh with extra batteries while the Anker stays fixed at 1024Wh. A household that plugs in a fridge, a router, lights, a fan and chargers at once will feel the DELTA 3 outlet advantage daily, and a household planning a bigger backup later will feel the expansion advantage permanently.

Recharge speed and weight

The Anker refills fully in about 49 minutes at 1600W HyperFlash through the app, while the DELTA 3 refills in about 56 minutes using combined AC and solar input. The Anker is also lighter at 24.9 lb against 27.5 lb, and more compact for its output. Both recharge fast by 1kWh standards; the Anker wins the wall-only race, the DELTA 3 wins when solar joins the wall input.

Choose Anker SOLIX C1000 Gen 2 Portable Power Station if…

  • Your appliances need 2000W output or a UPS switchover for a router
  • The fastest wall recharge matters, and you will enable HyperFlash in the app
  • Your load list is fixed at or below 1kWh
  • A lighter, more compact 1kWh body matters for storage

Choose EcoFlow DELTA 3 Portable Power Station if…

  • Your household plugs in many devices at once and needs 13 outlets
  • You may need more than 1kWh later and want expansion to 5kWh
  • Combined AC and solar recharge suits your setup
  • You prefer EcoFlow port layout and expansion ecosystem

Questions, answered

Which is better for a fridge?

Both cover a modern fridge for a useful period at 1kWh, but the Anker stronger 2000W output handles startup surges and kitchen appliances better, while the DELTA 3 extra outlets and expansion suit a fridge plus a longer household load list. For a fridge alone, take the Anker; for a fridge plus everything else, take the DELTA 3.

Can either expand past 1kWh?

Only the DELTA 3, which expands to 5kWh with extra batteries. The Anker C1000 Gen 2 has no battery expansion, so outgrowing 1024Wh means buying a larger unit instead.

Which recharges faster?

The Anker, at about 49 minutes fully charged using HyperFlash through the app, against about 56 minutes for the DELTA 3 using combined AC and solar input. Both are fast for the class, and both quoted speeds assume their stated input conditions.
