Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3 Plus: The Ultimate 1kWh Showdown (2026)

Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3 Plus: The 2026 Rematch

The Anker SOLIX C1000 Gen 2 just changed the math in the 1kWh power station class. Our previous comparison of the original C1000 vs the DELTA 3 Plus gave EcoFlow the edge on features despite a higher price. The Gen 2 closes every gap and opens new ones. With 2,000W output, a 49-minute full charge, and two 140W USB-C PD 3.1 ports in a smaller, lighter package, the question is no longer whether Anker can compete — it is whether EcoFlow can keep up.

Output Power

The Gen 2 delivers 2,000W continuous output — a 200W advantage over the DELTA 3 Plus’s 1,800W. That extra headroom means running a 1,500W space heater with capacity left for charging a phone, or handling a 1,800W hair dryer without approaching the limit. The DELTA 3 Plus fights back with a higher 3,600W surge rating versus 3,000W, which gives it a slight edge on motor-start loads like some older refrigerator compressors. In practice, both stations handle the same household appliances — the C1000 Gen 2 just does it with more breathing room during sustained loads.

Charging Speed

This is where the Gen 2 pulls decisively ahead. A 49-minute full charge versus 56 minutes may not sound dramatic, but it represents a 12% speed improvement that compounds in daily use. If you are topping off between activities — plugging in during lunch, charging before an evening event — those 7 minutes add up. Solar charging also favors the Gen 2: 600W maximum input versus 500W means faster off-grid replenishment with panels like the Jackery SolarSaga 200W or EcoFlow 400W.

USB-C and Port Quality

The C1000 Gen 2’s two 140W USB-C PD 3.1 ports are a clear generational leap. They charge a MacBook Pro 16-inch at full speed — something the DELTA 3 Plus’s 100W USB-C ports cannot do. For users with USB-C laptops, tablets, and monitors, this alone can be a deciding factor. A third 15W USB-C port handles accessories, and the single USB-A port covers legacy devices. The DELTA 3 Plus matches on AC outlet count (5 each) and includes a car outlet, but falls behind on USB-C capability.

Expandability

This is the DELTA 3 Plus’s strongest card. EcoFlow’s ecosystem lets you add batteries to reach 5kWh — nearly five times the base capacity. For home backup users who want a system that grows with their needs, this is a significant advantage. The C1000 Gen 2 is a closed system: 1,024Wh is all you get. If a full refrigerator backup through a 24-hour outage requires more than 1kWh, you would need a second unit or a larger station like the Jackery Explorer 2000 v2. If expandability is your top priority, the DELTA 3 Plus wins this category outright.

UPS and Home Backup

Both stations now offer UPS mode, which was a DELTA 3 Plus exclusive in the Gen 1 comparison. The C1000 Gen 2’s 10ms switchover is actually faster than the DELTA 3 Plus’s 20ms, though both are fast enough to keep computers and networking equipment running through grid transitions. For home office backup, either station works. For dedicated UPS protection, see our guide comparing power stations and traditional UPS systems.

Portability

At 23.9 lbs, the C1000 Gen 2 is over a pound lighter than the DELTA 3 Plus (25 lbs) and 3 lbs lighter than the original C1000 (26.9 lbs). Combined with the 14% smaller footprint, the Gen 2 is noticeably easier to pack in a car, carry to a campsite, or move between rooms during an outage. If weight matters — and for a device you carry — it should.

Price and Value

Here the comparison gets nuanced. The DELTA 3 Plus has a lower MSRP at $649 versus $799 for the C1000 Gen 2. But the Gen 2 frequently drops to $470 on Amazon sales, making it the cheaper option in practice. Even at full retail, the Gen 2’s higher output, faster charging, and better USB-C ports arguably justify the $150 premium. The DELTA 3 Plus’s value proposition rests on its expandability — if you plan to add batteries, the lower base cost plus expansion options may be more economical than buying a larger standalone unit.

Verdict

The Anker SOLIX C1000 Gen 2 is the better power station for most buyers. It charges faster, outputs more power, delivers superior USB-C performance, weighs less, and frequently costs less on sale. The original C1000 vs DELTA 3 Plus comparison was close — this one is not.

Choose the Anker SOLIX C1000 Gen 2 if you want the fastest charging, highest output, and best USB-C ports in the 1kWh class. It is the better standalone power station by every measurable spec except expandability and surge.

Choose the EcoFlow DELTA 3 Plus if you need expandable capacity up to 5kWh, want EcoFlow’s superior app ecosystem with smart home integrations, or prefer the higher 3,600W surge for demanding motor-start loads. It remains an excellent station — just no longer the default recommendation in this class.
