The storm warning comes in on a Friday afternoon. You’ve narrowed it down to two names, EcoFlow and Anker SOLIX, and you have one evening to decide before the stores and the delivery slots fill up. Here’s the honest EcoFlow vs Anker SOLIX comparison, size for size.

The short answer: it’s close, so match the size first. Anker SOLIX gives more AC output at 1 kWh and is the lighter pick at 2 kWh. EcoFlow gives more outlets, more solar input and easier expansion at 1 and 2 kWh. For whole-home backup, both have a strong 120/240V station.

Prices change often. The prices below are what we saw on each maker’s own store in October 2026; check the current price before you buy. Amazon prices may differ.

Several prices were sales: EcoFlow listed the DELTA 3 Plus at $799, the DELTA 3 Max Plus at $1,599 and the DELTA Pro 3 at $3,699. Anker’s prices change often; check the live price on the day you buy.

Capacity and output

At 1 and 2 kWh the capacities are identical: 1,024 Wh and 2,048 Wh on both sides. Output is where they split. At 1 kWh, the Anker C1000 Gen 2 gives 2,000 W against the DELTA 3 Plus’s 1,800 W. At 2 kWh it flips: the DELTA 3 Max Plus gives 3,000 W (6,000 W surge) against the C2000 Gen 2’s 2,400 W (4,000 W surge). For home backup, the DELTA Pro 3 stores more (4,096 vs 3,840 Wh), while the F3800 Plus puts out more (6,000 vs 4,000 W). Both big units offer 120V and 240V, so they can run 240V loads like a well pump through the right outlet.

Outlets: EcoFlow lists six AC outlets on the DELTA 3 Plus and four 20-amp outlets on the DELTA 3 Max Plus. Anker counts 10 ports in total on the C1000 Gen 2, and the C2000 Gen 2 adds a TT-30R RV outlet. The DELTA Pro 3 has seven AC outlets (including TT-30 and L14-30); the F3800 Plus has eight (including TT-30R and L14-30R).

Charging speed

Anker quotes 0-100% in 49 minutes for the C1000 Gen 2 using UltraFast charging (1,600 W). You switch it on in the app, and Anker says the battery must be above 68°F. EcoFlow quotes 0-100% in 56 minutes for the DELTA 3 Plus. At 2 kWh, EcoFlow quotes 0-80% in 64 minutes for the DELTA 3 Max Plus and Anker 0-100% in 88 minutes for the C2000 Gen 2 from the wall (58 minutes with wall and solar together). At the top, EcoFlow quotes 0-80% in 50 minutes for the DELTA Pro 3; Anker gives the F3800 Plus 1,800 W of wall charging, and up to 6,000 W from a 240V generator, but no wall-only charge time.

Solar charging

EcoFlow wins at 1 and 2 kWh: 1,000 W of solar on the DELTA 3 Plus and DELTA 3 Max Plus, against 600 W on the C1000 Gen 2 and 800 W on the C2000 Gen 2. For home backup, Anker leads: 3,200 W on the F3800 Plus against 2,600 W on the DELTA Pro 3. Panels rarely deliver their full rating, so size your array with some margin. Our solar generator guide covers panel pairing.

Battery life

Both brands use LiFePO4 at these sizes, and here the numbers do line up. EcoFlow rates the DELTA 3 Plus and DELTA Pro 3 for 4,000 cycles to 80%. Anker rates the C1000 Gen 2 and C2000 Gen 2 for 4,000 cycles to 80%. Anker lists the F3800 Plus at 3,000+ cycles without a percentage, and EcoFlow doesn’t state a cycle count for the DELTA 3 Max Plus. See LiFePO4 vs lithium-ion for why these batteries last.

Expandability and home backup

• 1 kWh: the DELTA 3 Plus grows to 5 kWh with extra batteries. Anker says the C1000 Gen 2 is not expandable (the older C1000 is).
• 2 kWh: the DELTA 3 Max Plus grows to 10 kWh; the C2000 Gen 2 doubles to 4 kWh with one BP2000 (Gen 2) battery.
• Home backup: the DELTA Pro 3 reaches 12 kWh with two extra batteries, and EcoFlow says a full system can reach 48 kWh. The F3800 Plus takes up to six BP3800 batteries, and Anker says two linked units reach 53.8 kWh.

To power your home’s circuits, both brands sell hardware that a licensed electrician installs: EcoFlow’s Smart Home Panel 2 (EcoFlow says it requires installation before use) and Anker’s Home Power Panel, transfer switch or inlet box options for the F3800 Plus. Never plug a station into a wall outlet to feed the house; that “backfeeding” endangers utility workers and your wiring. More in our home backup guide.

UPS mode and the app

Both switch to battery fast when the grid drops: under 10 ms on the DELTA 3 Plus and DELTA 3 Max Plus, 10 ms on the DELTA Pro 3, and 10 ms on the C1000 Gen 2 and C2000 Gen 2. On the F3800 Plus, Anker says only the three left-hand standard outlets have UPS. Both brands have apps; the DELTA 3 Plus and C1000 Gen 2 connect over Wi-Fi and Bluetooth.

Warranty

• EcoFlow: 5 years on the DELTA 3 Plus, DELTA Pro 3 and DELTA 3 Series Smart Extra Battery; 3 years plus 2 more when you register on the DELTA 3 Max Plus. Bought from EcoFlow or an authorized seller.
• Anker SOLIX: 60 months (5 years) on the C1000 Gen 2, C2000 Gen 2 and F3800 Plus. Anker’s policy lists its expansion batteries, including the BP2000 Gen 2, at 24 months. Bought from Anker or an authorized reseller, with proof of purchase.

On the stations themselves it’s a tie at five years. If you plan to add batteries, note that EcoFlow covers its DELTA 3 extra battery for 5 years while Anker lists 2 years for its expansion batteries.

Price

Both makers run frequent sales and their store prices change often, so compare the live price of each matched pair before you buy. EcoFlow’s extra solar input, outlets and expansion (and, at 2 kWh, extra output) are what the difference buys. There’s no federal tax credit for portable power stations in 2026.

Who should buy which

1. EcoFlow DELTA 3 Plus: best 1 kWh if you’ll add batteries or solar

What about small stations? EcoFlow’s RIVER 3 Plus (286 Wh, 600 W, three AC outlets, expandable to 858 Wh, about $299 from EcoFlow, 5-year warranty) has no exact Anker twin in our catalog. The closest, the Anker SOLIX C300 DC (288 Wh), has no AC outlets at all: it runs USB-C and USB-A devices such as phones, laptops and fans. It was sold out on Anker’s store when we checked.

How to choose the right size

• Output first: add the watts of everything that runs at once; check motor start-up surge against the surge rating.
• Usable energy: capacity × 0.85, because about 15% is lost in the inverter and conversion. A 1,024 Wh station gives roughly 870 Wh; 2,048 Wh about 1,740 Wh; 3,840 Wh about 3,260 Wh; 4,096 Wh about 3,480 Wh.
• Fridges by daily use: a fridge whose EnergyGuide label says 400 kWh a year uses about 1.1 kWh a day. Our estimate: about 19 hours on 1 kWh, 38 hours on 2 kWh, about 3 days on the F3800 Plus and a little over 3 days on the DELTA Pro 3, before solar. Starting surge still has to fit.
• Medical devices: for a CPAP, talk to your doctor or equipment supplier first. Our CPAP guide covers the details.

EcoFlow vs Anker SOLIX questions

Is Anker SOLIX better than EcoFlow?

Neither wins everywhere. At 1 kWh, Anker’s C1000 Gen 2 has more output, while EcoFlow’s DELTA 3 Plus adds solar input, outlets and expansion. At 2 kWh, EcoFlow has more output and solar; Anker is lighter. For home backup, EcoFlow stores more and Anker puts out more. Match the model to your loads.

Which has the better warranty, EcoFlow or Anker?

For the stations, they tie at five years: Anker lists 60 months on the C1000 Gen 2, C2000 Gen 2 and F3800 Plus, and EcoFlow gives 5 years on the DELTA 3 Plus and DELTA Pro 3 (3+2 with registration on the DELTA 3 Max Plus). Add-on batteries differ: EcoFlow lists 5 years for its DELTA 3 extra battery, Anker 24 months for its expansion batteries.

Can I expand the Anker SOLIX C1000 Gen 2?

No. Anker says the C1000 Gen 2 does not have an expansion feature, unlike the original C1000. If you think you’ll want more capacity later, look at the C2000 Gen 2 (to 4 kWh with a BP2000 Gen 2) or EcoFlow’s DELTA 3 Plus (to 5 kWh).

Can these power my whole house?

The DELTA Pro 3 and F3800 Plus can power selected home circuits, including 240V loads, through a panel, transfer switch or inlet installed by a licensed electrician. They won’t run a typical whole house for long, especially central air or electric heat. Smaller stations are for plugging appliances in with cords, never for feeding a wall outlet.

Can I use them indoors?

Yes. Battery power stations produce no exhaust, so they’re fine indoors. That’s the big safety difference from gas generators, which the CPSC says must run outside, at least 20 feet from the house, and never in a garage. See portable power station vs generator.
