EcoFlow DELTA 3 Portable Power Station, 1024Wh, 1800W (EF-DL-H10-3)

EcoFlow DELTA 3 Review: A 1 kWh Power Station That Reaches the Duxtop's 1,800 W

The EcoFlow DELTA 3 is a 1,024 Wh lithium iron phosphate (LiFePO4) power station with a 1,800 W continuous AC rating. That rating is the reason it's on this site. It's one of the few stations near the 1 kWh size whose continuous output reaches the full 1,800 W draw of the Duxtop 9100MC induction cooktop. It also has a 12 V car socket for a compressor fridge, a 500 W solar input and a 1,500 W AC charger, and it weighs 27.6 lb.

What the Amazon link sells: the listing titled "EF ECOFLOW Delta 3 Portable Power Station, 1024Wh 1800W" (ASIN B0DCBYMC9D, model EF-DL-H10-3, size option "DELTA 3"). This is the plain DELTA 3. It is not the DELTA 3 Plus (model EF-DL-H10-4), which was out of stock on Amazon when we checked, and it's not the DELTA 3 Classic (EF-DL3-C), which the Classic's own listing says doesn't accept the DELTA 3 Series extra batteries. It's also not a solar-panel bundle. When we checked, Amazon showed the listing in stock.

This review is research-based. VanLifeKitchens doesn't test products hands-on. The specs come from EcoFlow's DELTA 3 user manual and US product page, and from the Amazon listing. Runtime figures are our estimates, and each one shows its arithmetic and assumptions.

Choose this if:

• You want to run the Duxtop 9100MC at full power from a portable station, and you accept that 1,800 W uses the whole continuous rating.
• You'd like the option to add capacity later. EcoFlow lists DELTA 3 Series, DELTA 2, DELTA 2 Max and DELTA Pro 3 extra batteries, up to 5 kWh.
• You can recharge from shore power or a large solar array. The 1,500 W AC input is the fastest way to refill the battery.

Skip this if:

• You want headroom above 1,800 W for a cooktop plus other AC loads. A 1 kWh station can't give you that. You'd need a larger station, or a fixed inverter system put in by a qualified installer.
• You only need to run a 12 V fridge and charge phones. The Jackery Explorer 500 v2 is about half the weight for that job.
• Your van sits in hot sun for long stretches. EcoFlow's charge and discharge limits top out at 113°F (45°C), and its optimal range is 68–86°F.

What it is

A portable power station puts a battery, an inverter, a charger and a set of output ports in one box. It isn't wired into the van. You charge it from a wall outlet, a solar panel or the car socket, then plug your loads into it. For car and van campers without a built-in electrical system, that's the whole appeal: a fridge, lights and devices run from one box, and nothing needs permanent wiring.

The DELTA 3 is EcoFlow's 1 kWh model in that format. Its manual lists six AC outlets on the US version, two USB-A and two USB-C ports, two DC5521 barrel outputs, and one 12 V car socket. Inputs are an AC socket and one XT60 port, which takes either solar or car charging.

Specifications and sources

EcoFlow's US product page also lists a 5-year warranty, IP65 protection for the battery pack, and a UPS switchover under 10 ms. The Amazon listing gives the warranty as 5 years too. In the "What's in the box" section, the Amazon listing names only the AC charging cable and the manual, while EcoFlow's manual also lists a car charging cable and a DC5521-to-DC5525 cable. Check the box contents when it arrives.

Usable Wh vs rated Wh

The 1,024 Wh on the label is the battery's rated energy. You get less than that from the AC outlets, because the inverter turns some energy into heat while it converts battery DC to 120 V AC. Our power station and induction guide assumes 85–90% inverter efficiency. On that basis:

Usable AC energy (estimate): 1,024 × 0.85 = about 870 Wh, and 1,024 × 0.90 = about 922 Wh.

EcoFlow doesn't publish an efficiency figure in the manual we opened. Treat 870–922 Wh as a planning range, not a promise. Real efficiency drops at very light loads and in cold weather.

Can it run the Duxtop 9100MC at 1,800 W?

Yes, but only just. The DELTA 3's continuous AC rating is 1,800 W at 120 V. The Duxtop's maximum is 1,800 W. That's an exact match, with no headroom. Anything else on the AC side while the cooktop is on full power, such as a laptop charger or a kettle, can push the total over the rating and trip the overload protection. EcoFlow's manual describes an overload warning and tells you to disconnect some devices to reduce the load.

How long, at full power (estimate): usable Wh ÷ cooktop W = hours.

• 870 Wh ÷ 1,800 W = 0.48 h, or about 29 minutes
• 922 Wh ÷ 1,800 W = 0.51 h, or about 31 minutes

Assumptions: the station starts full, the inverter is 85–90% efficient, the cooktop draws its full 1,800 W the whole time, nothing else is plugged in, and there's no reserved capacity. That's the same method and the same result as the 1,024 Wh row in our induction guide.

Don't count on X-Boost. EcoFlow's manual says X-Boost lets the station run appliances rated above its output by lowering the voltage. The manual lists 2,600 W at 120 V with X-Boost, says it suits heating devices such as electric blankets, and warns that devices with voltage protection "may stop working due to low voltage." The Duxtop manual lists an E3 error for input voltage that's too high or too low. Plan around the 1,800 W continuous rating at normal voltage. EcoFlow also says X-Boost is off by default and is unavailable while the station is charging from AC.

The Nuwave PIC Gold is the easier fit. At its 1,500 W default, the Nuwave PIC Gold leaves about 300 W of headroom on this station. Estimated runtime at a steady 1,500 W is 870 ÷ 1,500 = 0.58 h, about 35 minutes, up to 922 ÷ 1,500 = 0.61 h, about 37 minutes. Its 900 W and 600 W caps leave more headroom still. Nuwave doesn't publish measured draw at those settings, so check with a watt meter or the station's display.

A typical camp meal doesn't use full power for half an hour. Our induction guide works through a 20-minute cook at a steady 1,000 W: about 370–392 Wh from the battery, so roughly two and a half cooks per full charge on a 1,024 Wh station. That leaves little for the fridge if you can't recharge the same day.

Running a 12 V fridge from the car socket

For most van and car campers, the fridge is the load that runs all day and night, so the 12 V socket matters more than the AC rating. EcoFlow's manual rates the DELTA 3's car socket at 12.6 V, 10 A, sharing 126 W with the two DC5521 ports. That's above the published maximums of the fridges we cover. Dometic rates the CFX5 35 at a 7.6 A maximum at 12 V. EcoFlow's manual also says to make sure the socket can meet an appliance's starting current, "subject to actual testing."

How many days of fridge (estimate). We use the same published figures as our power budget guide: ICECO's 430 Wh per 24 hours lab figure for the ICECO VL35 ProS, and about 320 Wh per day for the Dometic CFX5 35, from Dometic's US rating at 90°F ambient. EcoFlow doesn't publish the conversion efficiency of its 12 V output, so we use the same 85–90% range as for AC. That probably underestimates the DC path slightly.

Arithmetic: 870 ÷ 430 = 2.0 and 922 ÷ 430 = 2.1, and 870 ÷ 320 = 2.7 and 922 ÷ 320 = 2.9. Real use depends on ambient temperature, setpoint, door openings and how warm your groceries are when they go in. Plug your own fridge into the fridge battery calculator.

One setting to know about: EcoFlow's manual describes an AC timeout that switches off idle AC outlets. It says this can catch intermittent loads such as refrigerators, and recommends setting the timeout to "never" in the app when food matters. That's for a fridge on an AC outlet. Running a 12 V fridge from the car socket avoids the inverter entirely, so it's the more efficient route.

Recharging: AC, solar and car

• AC (wall or shore power): EcoFlow lists 1,500 W of AC charging, and the Amazon listing claims a full charge in 56 minutes when combined with solar. At a campground hookup, that's the quickest way to refill.
• Solar: one XT60 input, 11–60 V, 15 A, 500 W maximum. A panel's rated wattage is a best case. Real output depends on sun angle, cloud, heat and shading. As an estimate, replacing 870 Wh at an average 250 W of net solar would take roughly 3.5 hours of good sun (870 ÷ 250), plus charging losses.
• Car socket: the same XT60 port takes 12 V at up to 8 A, about 96 W. As an estimate, a full recharge from empty would take 1,024 ÷ 96 = about 10.7 hours of driving, more with losses. EcoFlow's manual says to connect the cable after the vehicle has started. Car charging tops the station up on a driving day. It won't refill a station that ran a cooktop.
• Alternator charger: EcoFlow sells an 800 W Alternator Charger that the manual lists as compatible. It's a permanent connection to the vehicle's electrical system, so it isn't a plug-in accessory. Follow EcoFlow's installation instructions and have a qualified installer fit it where your vehicle maker, local codes or your insurer require one.

Temperature limits and safety

Lithium batteries have charging and storage temperature limits, and the DELTA 3's are narrower than a hot van in summer:

• Charging: 32–113°F. Below freezing, the battery shouldn't take a charge. The manual shows a low-temperature warning and tells you to move the station somewhere warmer.
• Discharging: 14–113°F, with an optimal operating range of 68–86°F.
• Storage: EcoFlow says not to store it above 113°F or below 14°F, and to keep it dry and well ventilated, away from intense heat. For long-term storage it asks you to discharge the battery to 0% and recharge it to 60% every three months. It notes that the warranty won't cover a unit left uncharged or undischarged for more than six months.

A parked van in direct sun can exceed 113°F inside. EcoFlow's DELTA 3 manual doesn't use the word "unattended." (Jackery's Explorer 500 v2 manual does: it says not to leave the battery charging unattended for long periods.) EcoFlow's charging range and its instructions to keep the station away from heat sources and not to block its heat dissipation point the same way. Don't leave the station charging in a closed, hot van. Charge it while you're around, in shade or in a cooler spot. EcoFlow also tells you to set it on a stable, flat surface and to keep it out of reach of children and pets.

When it runs a cooktop at full power, the station works near its limit. Its fans run hard, and it can cut output if it overheats. Keep its vents clear and away from the cooktop's own exhaust. Induction still makes steam and grease in the pan, so the ventilation guide still applies.

This is a plug-in device. Don't wire it into a van's fixed electrical system or a shore-power inlet yourself. Any permanent install should follow the manufacturer's instructions and be done by a qualified RV electrical technician where codes or insurers require one. The battery bank guide explains the fixed-system alternative.

How it fits a van or camp kitchen

The DELTA 3 makes most sense as the one box that runs everything for someone with no house battery. A 12 V fridge goes on the car socket, phones and a laptop on USB-C, and an induction cooktop on AC for short bursts. At 15.7 x 8.0 x 11.2 inches it fits under a bench or behind a seat, but at 27.6 lb it's a two-handed lift. Strap it down. A 27 lb box needs a real anchor point in a vehicle, not a bungee.

Where it struggles is energy, not power. Cooking every meal on induction and running a fridge needs more than 1 kWh a day, as our power budget guide shows for two people. The DELTA 3 can deliver the watts, but you have to put the energy back each day. If you can't count on that, cook some meals on gas, and see the induction vs butane vs propane guide for that trade-off.

Limitations

• No headroom for the Duxtop. 1,800 W continuous matches the cooktop's maximum exactly.
• One DC input. Solar and car charging share the XT60 port, so you can't run both at once through it.
• Slow car charging. About 96 W from a 12 V socket.
• Narrow temperature window. Charging stops below 32°F, and the upper limit for everything is 113°F.
• Weight. 27.6 lb is heavier than the 23.8 lb Jackery Explorer 1000 v2, although the Jackery's lower 1,500 W rating can't run the Duxtop at full power.

How it compares

• Jackery Explorer 1000 v2: slightly more capacity (1,070 Wh) and lighter, but rated at 1,500 W continuous. It suits the PIC Gold and not the Duxtop at full power. See EcoFlow DELTA 3 vs Jackery Explorer 1000 v2.
• Anker SOLIX C1000: the same 1,800 W rating, 1,056 Wh, a 600 W solar input and a wider discharge range in the cold, but a lower 3,000-cycle rating and a narrower charging range. See Anker SOLIX C1000 vs EcoFlow DELTA 3.
• Jackery Explorer 500 v2: half the capacity and too small for either cooktop, but much lighter. It suits fridge-and-devices use.

Verdict

The DELTA 3 is a sensible choice for a van or car camper who wants one portable box to run a fridge, charge devices and run an 1,800 W induction cooktop. It does that last job at the very edge of its rating, for roughly half an hour of full power per charge (estimate). Its strengths are documented: a 4,000-cycle LFP rating, a 10 A car socket, a 1,500 W AC input, expansion batteries and EcoFlow's 5-year warranty. Its limits are just as specific: no headroom at 1,800 W, slow car charging, and a 113°F ceiling that a summer van can exceed.

FAQ

Can the EcoFlow DELTA 3 run an 1,800 W induction cooktop? Its continuous AC rating is 1,800 W, which equals the Duxtop 9100MC's maximum, so it can, with no headroom. Our estimate is about 29–31 minutes at full power from a full charge, assuming 85–90% inverter efficiency. Don't run other AC loads at the same time. Don't rely on X-Boost either, because it lowers the voltage, and the Duxtop's manual lists a voltage error.

How long will the DELTA 3 run a 12 V fridge? As an estimate, about 2.0–2.1 days for a fridge using 430 Wh a day (ICECO's lab figure for the VL35 ProS), or about 2.7–2.9 days at 320 Wh a day (Dometic's US rating for the CFX5 35 at 90°F ambient). That assumes 85–90% of the 1,024 Wh is usable and no charging. Hot weather and frequent opening shorten it.

How many amps is the DELTA 3's 12 V car socket? EcoFlow's manual rates it at 12.6 V and 10 A, with 126 W shared between the car socket and the DC5521 ports.

Is the DELTA 3 the same as the DELTA 3 Plus? No. The Amazon listing we link sells the DELTA 3, model EF-DL-H10-3. The DELTA 3 Plus is model EF-DL-H10-4, and the DELTA 3 Classic is EF-DL3-C. This review's specs come from the DELTA 3 (EF-DL-H10-3) manual.

Can I charge the DELTA 3 in freezing weather? EcoFlow's charge range is 32–113°F (0–45°C), so not below freezing. It can discharge down to 14°F. Warm the station before you charge it.

How fast does it charge from solar? The XT60 input accepts 11–60 V at up to 15 A, with a 500 W maximum. Real solar output is usually below a panel's rating. As an estimate, an average 250 W of net solar refills about 870 Wh in roughly 3.5 hours of good sun, plus losses.

Can it be installed permanently in a van? It's a plug-in device. Any permanent wiring, including EcoFlow's 800 W Alternator Charger, should follow EcoFlow's installation instructions and be done by a qualified installer where codes or insurers require one.
