Anker SOLIX C1000 Portable Power Station with Car Charging Cable, 1,056Wh (A1761) vs EcoFlow DELTA 3 Portable Power Station, 1024Wh, 1800W (EF-DL-H10-3)

The short answer

These two are the closest match in this category. Both are 1 kWh LiFePO4 stations rated for 1,800 W continuous, so both can run the Duxtop 9100MC at full power, with no headroom, for roughly half an hour per charge by our estimate. Both have a 10 A car port for a 12 V fridge. The choice comes down to where and how you camp.

For most van readers, the EcoFlow DELTA 3 is the better fit. Its charging and discharging limits go up to 113°F, against the Anker's 104°F, which matters in a van in summer. It also has a higher cycle rating (4,000 cycles to 80%, against 3,000 to 80%) and a wider choice of expansion batteries.

The Anker SOLIX C1000 is the better pick for cold-weather and solar-heavy trips. It discharges down to -4°F (the DELTA 3 stops at 14°F), accepts up to 600 W of solar (the DELTA 3 takes 500 W), holds slightly more energy, and comes with a car charging cable according to its listing title.

Induction cooking

Both continuous ratings equal the Duxtop's 1,800 W maximum. Neither leaves room for another AC load while the Duxtop is on full power.

Estimated runtime at a steady 1,800 W:

• C1000: 1,056 × 0.85 = 898 Wh, and 898 ÷ 1,800 = about 30 minutes. At 90%, 950 ÷ 1,800 = about 32 minutes.
• DELTA 3: 1,024 × 0.85 = 870 Wh, and 870 ÷ 1,800 = about 29 minutes. At 90%, 922 ÷ 1,800 = about 31 minutes.

Anker's own FAQ says about 20% of capacity is lost to heat and conversion. On that basis the C1000 gives about 28 minutes (1,056 × 0.80 ÷ 1,800). EcoFlow doesn't publish an equivalent figure.

Boost modes don't add cooking headroom on either. EcoFlow's X-Boost and Anker's SurgePad both run high-wattage appliances by reducing the power delivered. Both makers say they suit heating devices and aren't for devices with voltage protection or strict voltage requirements. The Duxtop manual lists a voltage error, and the PIC Gold manual gives an 85–144 V window. Treat 1,800 W as the ceiling on both. Anker's SurgePad switches on automatically when output exceeds the rating, while EcoFlow's X-Boost is off by default and enabled in the app.

Nuwave PIC Gold at 1,500 W: both leave about 300 W of headroom. Estimated runtime is about 36–38 minutes on the C1000 and about 35–37 minutes on the DELTA 3.

All runtimes assume a full start, a steady draw at the stated wattage, nothing else plugged in, and 85–90% inverter efficiency.

Edge: Tie. The C1000's extra 32 Wh is about a minute at full power.

Running a 12 V fridge

Both car ports are rated at 10 A. Estimated runtime on the same published fridge figures used in our power budget guide:

Anker's FAQ answers a fridge owner's question by saying the C1000X's 12 V socket is regulated to around 13.4 V as the battery drains. The C1000X shares the C1000's A1761 user guide, but the answer names only the C1000X. Anker also has a Car Port Saving Mode that switches the port off after 5 hours below 3 W. Turn it off for a fridge. EcoFlow's manual rates the DELTA 3's socket at 12.6 V and notes an AC timeout that can affect a fridge plugged into AC.

Edge: Tie, with a slight capacity edge to the C1000.

Recharging

• Solar: the C1000 takes up to 600 W (11–60 V, 10 A below 32 V and 12.5 A above). The DELTA 3 takes up to 500 W (11–60 V, 15 A). With enough panels, the Anker refills faster on a sunny day. As an estimate, 300 W of average net solar refills about 898 Wh in 3 hours, while the DELTA 3's limit allows 500 W at best.
• AC: EcoFlow lists 1,500 W, and Anker 1,300 W. Both claim a full charge in under an hour in their fastest modes.
• AC plus solar: Anker's FAQ says the C1000 can't use AC and DC inputs at the same time. EcoFlow's listing claims its 56-minute full charge using AC and solar together.
• Car: Anker says the C1000 draws about 120 W from a 12 V socket, and its listing title says a car charging cable is included. EcoFlow's manual lists 12 V at 8 A (about 96 W) and includes a car charging cable in its box list, though the Amazon listing's box contents don't mention one. A full recharge from a car socket takes roughly 9 hours on the C1000 and 11 hours on the DELTA 3, by our estimate.

Edge: Anker SOLIX C1000 for solar and car charging. EcoFlow DELTA 3 for combined AC and solar.

Temperature: heat vs cold

This is the clearest practical difference.

• Heat: the C1000 charges and discharges only up to 104°F. The DELTA 3 goes to 113°F. A van parked in summer sun can pass either figure, but 104°F is reached more often. For summer travel in hot regions, the DELTA 3 has more margin.
• Cold: the C1000 discharges down to -4°F, and the DELTA 3 down to 14°F. Neither charges below 32°F. For winter camping where the fridge and devices run overnight in a cold vehicle, the Anker keeps working at lower temperatures.

Lithium batteries have charging and storage temperature limits on both. Follow each maker's ranges. Don't leave either charging in a closed, hot van, and warm either one before charging in freezing weather.

Edge: DELTA 3 for heat, C1000 for cold. For most van travel, heat is the more common problem.

Battery life, expansion and warranty

Both rate cycles to 80% capacity, so the figures compare directly: 4,000 for the DELTA 3, 3,000 for the C1000. Both are manufacturer ratings, not measurements.

For expansion, EcoFlow lists DELTA 3 Series, DELTA 2, DELTA 2 Max and DELTA Pro 3 extra batteries, up to 5 kWh. Anker's FAQ says the C1000 works only with its BP1000 expansion battery, and only one of them. Both list 5-year warranties.

Edge: EcoFlow DELTA 3.

Size, weight and safety

The C1000 measures 14.8 x 8.07 x 10.5 inches and weighs 28.44 lb. The DELTA 3 measures 15.7 x 8.0 x 11.2 inches and weighs 27.6 lb. The Anker is a little more compact, the EcoFlow a little lighter. Neither is a one-handed carry, and both need securing in a moving vehicle.

On safety, both makers set temperature limits and ask for clear vents and dry storage. EcoFlow's manual says not to store the DELTA 3 above 113°F or below 14°F, and not to block its heat dissipation. Anker's FAQ says to store the C1000 dry and cool and to charge it fully at least once every three months in storage. Neither station is meant to be wired into a vehicle's fixed electrical system. EcoFlow's 800 W Alternator Charger, or a DC-to-DC charger on the Anker, is a permanent install. Follow the manufacturer's instructions and use a qualified installer where codes or insurers require one.

Edge: Tie.

Value

When we checked, the Anker SOLIX C1000 was listed for less than the EcoFlow DELTA 3 on Amazon. Prices on both move often, so check the buttons on the review pages. For the extra cost, the DELTA 3 offers a higher heat ceiling, 1,000 more rated cycles, more expansion options and a faster AC input. The C1000 offers more solar input, a lower cold limit and slightly more capacity for less. For a van that sees summer heat, the DELTA 3's extra cost buys margin you'll use. For a cold-climate or solar-first setup, the C1000 is the better value.

Which one should you buy?

Buy the EcoFlow DELTA 3 if:

• You travel in summer heat, where the 104°F limit on the Anker could interrupt charging or discharging.
• You want the higher cycle rating and the option to add capacity later.
• You charge from AC and solar at the same time.

Buy the Anker SOLIX C1000 if:

• You camp in cold weather and need the station to discharge below 14°F.
• You run a large solar array and want up to 600 W of input.
• You charge from the car often, and want the cable in the box and the slightly faster 12 V input.

If your cooktop is the Nuwave PIC Gold rather than the Duxtop, the lighter Jackery Explorer 1000 v2 is also worth comparing. See EcoFlow DELTA 3 vs Jackery Explorer 1000 v2.

FAQ

Can both run an 1,800 W induction cooktop? Yes. Both are rated at 1,800 W continuous, which equals the Duxtop 9100MC's maximum, so there's no headroom on either. As an estimate, that's about 30–32 minutes per charge on the C1000 and 29–31 minutes on the DELTA 3. Don't run other AC loads at the same time.

Do SurgePad and X-Boost let them run bigger cooktops? Not reliably. Both work by reducing the power delivered to heating appliances, and both makers say they aren't for devices with voltage protection. Induction cooktops check their supply voltage.

Which is better in hot weather? The DELTA 3. Its charge and discharge ranges go up to 113°F. The C1000's stop at 104°F.

Which is better in cold weather? The C1000. It discharges down to -4°F, while the DELTA 3 stops at 14°F. Neither charges below 32°F.

Which lasts more cycles? On the makers' ratings, the DELTA 3: 4,000 cycles to 80% capacity, against 3,000 to 80% for the C1000.
