EcoFlow Delta Pro 3 vs Anker Solix F3800: Which Portable Power Station is Best?

Jun 15, 2025

Need backup juice for your next blackout or glamp-fest? Between the EcoFlow Delta Pro 3 and Anker Solix F3800, EcoFlow takes the win for better value and solid performance. But don’t pack up yet—each has quirks worth knowing. Let’s plug into the world of portable power stations!

Technical Showdown: Core Specs, Design, & Charging

Power Output and Battery Performance

Continuous and Surge Wattage (Pmax vs. Psurge)

The EcoFlow Delta Pro 3 offers a continuous output of 4000W, which is already enough for most home appliances. However, the Solix F3800 delivers 3840W continuous output. With two units in split-phase, it can reach a combined 6000W for 240V applications.

In real-world tests, the Delta Pro 3 handled loads up to 4000W reliably. The Anker, meanwhile, reached up to 4200W with ease. That small bump could matter in surge-heavy scenarios.

Base Capacity and Lifespan (Wh and LiFePO4 Cycles)

The Delta Pro 3 comes with a 4096Wh capacity, while the Solix F3800 offers a slightly larger 3840Wh. Both use LiFePO4 batteries, known for their long cycle life and safety.

While exact cycle ratings weren’t listed, both are expected to deliver years of reliable performance under regular use.

Design, Ports, and Portability

Upright vs. Horizontal: A Footprint and Ergonomics Comparison

Design-wise, both power stations feature a vertical, upright layout, optimising space and ease of use. This form factor is well-suited for indoor corners or compact van setups.

There’s no significant difference in the general layout between the two, though users may notice minor differences in interface placement.

Weight, Wheels, and Handles

Portability plays a major role in day-to-day use. The EcoFlow Delta Pro 3 weighs 46kg, and the Anker Solix F3800 comes in just slightly heavier at 48kg.

Both units have integrated handles to help with lifting or rolling. However, neither unit can be considered truly “lightweight,” so wheels or carts may still be needed.

Available Outlets and Port Selection

The Anker Solix F3800 takes the lead in port variety, offering AC, DC, and USB ports. This makes it easier to connect different types of devices without adaptors.

The Delta Pro 3 includes AC outlets, USB-A and USB-C ports, DC outputs, and a 12V car socket—covering nearly all use cases, though Anker offers more port variety overall.

Charging Speeds and Solar Input

AC Charging: Time to Full from the Wall

Both power stations feature fast AC charging, but Anker edges out slightly here. The Solix F3800 charges in about 2.4 hours, while the Delta Pro 3 charges fully in around 1.5 hours with fast AC input, slightly faster than the Anker in most scenarios.

This difference isn’t drastic, but those in a hurry may appreciate the time saved.

Maximum Solar Input (Wsolar) and Voltage Range (Voc)

Both units are solar-ready, allowing users to recharge off-grid with panels. Exact voltage ranges weren’t listed, but both support high-input solar systems.

This makes either station a solid choice for vanlifers, campers, or emergency preppers relying on renewable power.

Combined Charging Capabilities

Each unit supports combined charging methods—using AC and solar simultaneously for faster recharge cycles. While performance specifics weren’t given, both deliver good flexibility for mixed-input scenarios.

Real-World Use Cases, Ecosystem, and Final Verdict

Home Integration and 240V Capability

The 120V/240V Output Showdown

When it comes to high-voltage output, the Anker Solix F3800 again pushes ahead with up to 6000W total output. This makes it more suitable for running 240V appliances in a backup scenario.

The EcoFlow Delta Pro 3 also supports demanding appliances, but at a slightly lower peak.

Smart Panel and Transfer Switch Compatibility

Both models support expansion and integration into home power systems. The Delta Pro 3 shines when it comes to modularity, offering support for extra battery packs and ecosystem add-ons.

The Solix F3800 also supports a growing ecosystem, including compatible accessories for whole-home use.

Uninterruptible Power Supply (UPS) Performance

Each device can serve as a reliable UPS during outages. While switchover times weren't specified, both provide stable power backup when the grid goes down.

This makes either model suitable for sensitive electronics or essential household appliances.

Who Should Buy Which Power Station?

The Case for the EcoFlow Delta Pro 3

If you're after a lower price, modular design, and excellent long-term performance, the EcoFlow Delta Pro 3 is a smart choice. It’s especially appealing for users wanting to build a scalable backup system.

The efficient solar charging and consistent performance make it ideal for home users, campers, and small businesses.

The Case for the Anker Solix F3800

The Anker Solix F3800 costs a bit more at £2,799, but you get higher output, more ports, and slightly faster charging. It’s well-suited for power users who need to support multiple devices or heavy appliances.

The extra £300 may be worth it if you need the power headroom or expanded connectivity.

Analysing Price, Warranty, and Long-Term Value

At £2,499, the Delta Pro 3 offers more bang for your buck. That said, Anker’s added power and connectivity might justify its higher price tag for some users.

Warranty specifics weren’t mentioned, but both brands are known for strong customer support and long-term reliability.
