Anker SOLIX F3000 vs EcoFlow DELTA Pro: Which Portable Power Station Is Right for You?

The way people think about power is changing.

For decades, if you wanted backup electricity, the go-to solution was a noisy, gas-burning generator. Today, with advances in lithium battery technology, powerful portable power stations have emerged as a clean, quiet, and flexible alternative.

These systems can run household appliances during outages, charge electronics at a campsite, or even power an RV or off-grid cabin for days at a time.

The Rise of the 3kWh Power Station

The rise of larger portable power capacity started in 2021 with the launch of the EcoFlow DELTA Pro Portable Power Station, a groundbreaking unit that redefined what portable power could do.

Before its arrival, most power stations were small, short-term solutions best suited for camping trips or occasional backup. The DELTA Pro changed that by setting a new benchmark — bringing whole-home backup capability, massive expandability, and serious off-grid potential into a single unit.

In the years since, other brands have entered the space, but none have advanced the category more than Anker. With the launch of the Anker SOLIX F3000 Portable Power Station in 2025, Anker has taken the 3kWh standard to the next level, delivering a lighter, more portable design with faster solar input and easier setup, passing by the long-loved DELTA Pro and making it the leading 3kWh power station on the market today.

Both offer multi-kilowatt storage, durable lithium iron phosphate (LiFePO₄) batteries, and advanced charging options. They are built to be centerpieces of your energy independence plan, whether that means weekend camping, full-time RV living, or whole-home backup power.

Despite their similarities, these two power stations are designed with very different users in mind.

The Anker SOLIX F3000 places greater emphasis on portability, high solar input, and quick setup for people who need reliable off-grid power on the move.

The EcoFlow DELTA Pro, on the other hand, is a heavyweight designed to scale into full-home energy systems with massive expandability.

This article will provide a detailed, side-by-side look at the SOLIX F3000 and DELTA Pro. We’ll cover specs, capacity, expandability, portability, charging, ports, battery life, pricing, and real-world use cases. By the end, you’ll have the clarity you need to decide which model best fits your lifestyle and power needs.

SOLIX F3000 vs DELTA Pro Spec Comparison

Before diving into detailed analysis, let’s look at how the two units stack up on paper. The following table compares key technical specifications that most buyers care about:

F3000’s TT-30R can supply up to 3,600W, while individual NEMA 5-20R outlets are rated 20A/2,400W each but are limited by the inverter’s total output. Both systems support 240V when paired with a second unit and the brand’s voltage hub.

The numbers tell a story. Both units use long-lasting LiFePO₄ batteries, both are expandable, and both support 240V when paired with a second unit. But the differences are clear: the F3000 emphasizes solar intake and portability, while the DELTA Pro emphasizes capacity and expandability.

Power & Capacity

When comparing power stations, capacity and output are usually the first factors buyers consider. Capacity, measured in watt-hours (Wh), tells you how much energy the unit stores. Output, measured in watts (W), tells you how much energy it can deliver at once.

The Anker SOLIX F3000 holds just over 3,000Wh. That’s enough to run a standard refrigerator for around 24–36 hours, a CPAP machine for weeks, or recharge a smartphone more than 200 times. Its inverter can output up to 2,400W through its standard outlets and as much as 3,600W through its TT-30R RV outlet. That means it can run high-draw appliances like a microwave, portable A/C, or induction cooktop — though you’ll need to monitor usage carefully if multiple devices run at once.

The EcoFlow DELTA Pro comes in at 3,600Wh capacity, which is roughly 20% more storage than the F3000. More importantly, its inverter provides 3,600W continuous output and 7,200W surge. That surge rating means it can handle starting loads from power-hungry appliances like sump pumps, air conditioners, or well pumps. For families who want a battery that can keep larger home systems running, that extra headroom is crucial.

In real-world terms:

• F3000 is best suited for off-grid cabins, RV trips, or backup for essentials like lights, Wi-Fi, and refrigeration.
• DELTA Pro can realistically support larger portions of a home, including critical 240V appliances when paired with another unit and a voltage hub.

Expandability & System Integration

Battery capacity alone doesn’t tell the full story. Expandability is where these two units diverge dramatically.

The Anker SOLIX F3000 allows expansion with up to three BP3000 batteries. Each adds another 3,072Wh, bringing the total to 12,288Wh. That’s enough to run a home fridge and lights for nearly a week. Expansion is plug-and-play, making it simple for RVers or cabin owners who want flexibility without wiring complexity.

The EcoFlow DELTA Pro, however, is designed to be part of an ecosystem. With Smart Extra Batteries, each unit can scale up to 25kWh. Add in EcoFlow’s Smart Home Panel, and the DELTA Pro becomes a whole-home backup system that can automatically switch on during outages and power multiple circuits. It’s also compatible with EcoFlow’s smart gas generator for hybrid setups.

For homeowners wanting a substitute for a traditional standby generator, the DELTA Pro’s system integration is unmatched. For people who primarily need portable power that scales within reason, the F3000’s approach is more practical.

Portability & Design

At first glance, the F3000 and DELTA Pro look similar: rectangular units with handles and wheels. But their design priorities are different.

The Anker SOLIX F3000 weighs just under 92 lbs, which is heavy but manageable. Its “suitcase” design, complete with telescoping handle and rugged wheels, makes it surprisingly easy to roll into place. For anyone moving the unit between a garage, RV, or campsite, this design feels intuitive.

The EcoFlow DELTA Pro weighs about 99 lbs, a bit heavier and bulkier. It also has wheels and a pull handle, but its larger frame makes it less convenient for frequent moves. Most owners treat it as semi-stationary — rolled into position and left there.

In short: if you’ll be moving your power station frequently, the F3000 is easier to handle. If your goal is a stationary backup hub, the DELTA Pro’s bulk isn’t an issue.

Charging Options

One of the biggest selling points for modern power stations is how quickly they can recharge. After all, a backup system that takes two days to recharge after an outage isn’t practical.

The Anker SOLIX F3000 excels in solar charging. Its dual MPPT setup accepts up to 2,400W of solar input — more than many competitors in its size class. That means with four 600W solar panels in good sunlight, the unit can recharge in just a few hours. Its AC charging is also fast, pulling up to 1,800W from a wall outlet. For RVers or off-grid cabins with robust solar setups, this flexibility is a huge advantage.

The EcoFlow DELTA Pro supports up to 1,600W of solar, slightly less than the F3000. However, it offers unique charging flexibility. It can pull 1,800W from AC, recharge at many EV charging stations, and even support combined “MultiCharge” rates up to 6,500W when using multiple inputs (AC + solar + gas generator). For homeowners who want to recharge quickly in any situation, that versatility is invaluable.

Bottom line: the F3000 is king of solar intake, while the DELTA Pro offers the most diverse charging options.

Ports & Outputs

Both models offer a wide range of ports, but the layout and design reveal their intended audiences.

The Anker SOLIX F3000 includes the following ports:

• 4 × NEMA 5-20R AC outlets (120V, 20A each)
• 1 × TT-30R RV outlet (up to 3,600W)
• 2 × USB-C (100W)
• 2 × USB-A
• 12V car outlet
• Anderson DC port

This balance of output ports makes it ideal for RV travelers, weekend campers, and anyone who needs to power everyday electronics and appliances — with the added advantage of being able to recharge directly from a portable generator.

The EcoFlow DELTA Pro includes the following ports:

• 4 × AC outlets (20A) + 1× 30A RV plug
• Multiple USB-C and USB-A ports
• 12V car and DC5521 ports
• Anderson port for DC applications

The DELTA Pro has more outlets overall, making it easier to run multiple devices at once without swapping cords. It’s especially useful for people powering both household and heavy-duty gear simultaneously.

Battery Life & Warranty

Both units use LiFePO₄ (LFP) chemistry, which is safer, more stable, and much longer-lasting than older lithium-ion batteries.

The F3000 is rated for 4,000+ cycles before reaching 80% of original capacity. The DELTA Pro is rated for about 3,500 cycles. In practice, that means both will last a decade or more under regular use.

Both also include a 5-year warranty, giving buyers confidence in long-term reliability.

Pricing & Value

Pricing varies by retailer and promotions, but both units sit in the premium tier of portable power stations. The Anker SOLIX F3000 usually comes in below the DELTA Pro, making it a better value for those who prioritize portability, solar performance, and affordability.

The EcoFlow DELTA Pro is more expensive, but for homeowners who want full-home backup capability, the added cost is justified. Its expandability and system integration simply go beyond what the F3000 offers.
