The Anker SOLIX C2000 Gen 2 is the better buy for most people choosing between these two. Both hold 2,048 Wh and put out 2,400 W, but the Anker adds a TT-30R RV outlet, takes 800 W of solar instead of 500 W, can add a second battery, and weighs 3 lb less. The EcoFlow DELTA 3 Max wins only if a lower listed noise figure in a bedroom or office matters most.
Every figure comes from Anker’s and EcoFlow’s US spec pages, plus two EcoFlow listing photos, all checked in November 2026. We have not tested either station, so this is a side-by-side reading of what each maker publishes.
Anker SOLIX C2000 Gen 2: more ways to charge and grow
Anker SOLIX C2000 Gen 2
- Capacity
- 2,048 Wh
- AC output
- 2,400 W
- Solar input
- 800 W
- Weight
- 41.7 lb
Who it's for: Home backup and RV buyers who want 2 kWh and a TT-30 outlet in a box lighter than most 2 kWh stations.
Strengths
- 2,400 W rated, 4,000 W peak
- TT-30 RV outlet
- 10 ms UPS switchover
Weaknesses
- Solar input tops out at 800 W
- Expands to only 4,096 Wh with one battery
The C2000 Gen 2 is the more flexible of the pair. It runs 2,400 W with a 4,000 W peak, and next to its NEMA 5-20R outlets is a TT-30R for a travel trailer. Two 140 W USB-C ports, a 15 W USB-C, a USB-A, and a 12V car socket round out the panel.
Charging is where it pulls ahead. AC input is 1,800 W, reaching 100% in 88 minutes. Solar input is 800 W through an XT-60i port at 11-60V, and AC plus solar together take 2,600 W and fill it in 58 minutes. An alternator charger can add up to 800 W while you drive. One BP2000 (Gen 2) battery takes it to 4,096 Wh.
The switchover is 10 ms, it discharges down to -4°F, and the warranty is 5 years. Anker’s own comparison table lists 30 dB. Its weak spot is the expansion ceiling: one extra battery is the limit.
EcoFlow DELTA 3 Max: the quieter house unit
EcoFlow DELTA 3 Max
- Capacity
- 2,048 Wh
- AC output
- 2,400 W
- Solar input
- 500 W
- Weight
- 44.7 lb
Who it's for: Home backup buyers who want 2 kWh with 20 A outlets in a quiet box.
Strengths
- 2,048 Wh with 2,400 W output
- 25 dB at 600 W (maker's test)
- Under 10 ms UPS switchover
Weaknesses
- Solar input only 500 W for a 2 kWh battery
- 0-80% takes 68 minutes on AC
- Heavy at 44.7 lb
The DELTA 3 Max is built for indoor standby. EcoFlow lists 25 dB or less at 600 W, measured at 1 m, and a switchover under 10 ms. Its four 120 V outlets handle 20 A each, and X-Boost lifts output to 3,400 W for suitable appliances.
It reaches 80% in 68 minutes on AC, and EcoFlow’s listing photo shows 0-80% in 3.41 hours from a car. Its other ports are a 100 W USB-C, two 30 W USB-C, an 18 W USB-A, and a 126 W car outlet.
Its limits are clear. Solar input stops at 500 W, so 0-80% on panels takes 3.43 hours. An expansion battery isn’t listed. It weighs 44.7 lb, discharges only down to 14°F, and its 5-year warranty requires EcoFlow app registration (3 years standard).

What does the extra solar input buy you?
The Anker’s extra 300 W of solar input shows up on a sunny day. At full rated input, 800 W of panels would put about 2,048 Wh in roughly 2.6 hours of ideal sun, while 500 W would need about 4.1 hours. Real panels rarely hold their rating all day, so treat these as best cases; Anker’s own figure is 100% in 3 hours on solar.
Per pound, the Anker stores about 49.1 Wh against about 45.8 Wh for the EcoFlow.
How to choose
- You tow a trailer with a 30 A plug: the C2000 Gen 2 has a TT-30R outlet.

- You may want more capacity later: the C2000 Gen 2 adds one battery; EcoFlow lists none for the DELTA 3 Max.
- The station sits in a bedroom: the DELTA 3 Max lists 25 dB or less at 600 W.
- You use it in freezing weather: the C2000 Gen 2 discharges down to -4°F.
