Anker Solix F3800 vs EcoFlow Delta Pro 3: Which Power Station Fits You Best?
Who Are These Power Stations For?
The Anker SOLIX F3800 and Ecoflow Delta Pro 3 are premium power stations. Both are popular in the community, well supported, and have been around long enough for them to be a trusted. While similar in their unmatched quality, each power station is unique in a few points.
Both of these models are sold as whole home-back up solutions. They are large, heavy, and meant to be wheeled out when the neighborhood goes dark.
However, both units come with wheels and are great options where you don’t have to move them often, such as throwing them into the bed of your pick up for the weekend away at the cabin, tailgating before the game, powering a backyard party, your camper, or vanlife outing.
At a Glance

The Good
Anker SOLIX F3800 Power Station
-
Very high continuous AC output and surge capability; can handle heavy loads and even dual 120/240V appliances.
-
Strong solar input capability of up to 2400W which allows for relatively fast solar recharging. In an ideal set up with maximum sunlight, you can fully recharge in less than two hours
-
Expandable up to 26.9kWh using up to 6 expansion batteries, it is built for semi-permanent backup setups or extra long outages.
-
Good warranty and long lifespan thanks to LiFePO₄ battery chemistry and sturdy components.
-
Includes a NEMA 14-50 (50 Amp) for high power needs.
EcoFlow Delta Pro 3
-
Excellent capacity output for household / whole backup power, combined with faster initial charge times.
-
Expandable up to 12kWh by adding two expansion batteries.
-
Has IP65 rating which means it can resist dust and water. But to be clear, don’t let it get rained on or linger in a dusty environment without proper protection. The IP rating gives you some protection but you should still use caution.
-
Solid app / user feedback on interface; multiple charging methods, scheduling, pass-through charging.
-
Compatible with older batteries and expansions which is great if you already invested into Ecoflow.
-
When paired with the Ecoflow Smart Generator, you get one of the best emergency total house backup power systems. The smart pairing keeps the battery topped off while requiring very little work from you. This pairing provides unparalleled, flexible power for countless situations.
-
Works with AC adapters which allows you to plug into a generator with 240V as well as an adapter for EV charger adapter.
- Has a 30 AMP Outlet making it super easy for RV power.
The Bad / Things to Be Aware Of
Anker Solix F3800
-
It’s heavy. At 132 lbs, it's not something a small person can easily lug around or lift. The wheels and handle helps but it is something to consider.
-
It has no IP rating meaning you must keep it out of dust or protect it from water.
-
It’s a premium power station so you do pay a higher price for the best.
-
The App can be finicky. App limitations: lack of detailed historical usage statistics; some users report unpredictable shutdowns / failures (e.g. AC input or output randomly dies) requiring resets.
-
While charging the power station with 120V, you cannot use 240V outlet.
EcoFlow Delta Pro 3
-
Also very heavy. At 113 lbs., it's not something a smaller person is just going to toss into the bed of pickup. However, if you just need to wheel it out and plug it in, that won’t be a problem.
-
Like the Anker power station, this is a premium unit so the price can be steep.
-
Complexity in solar and accessory compatibility; some users complain about needing extra adapters, mismatched components, or paying extra for things they expected to be included. The simple fix is to plan your solar ahead of time and do your research on what you need to make it all work together.
-
Probably the biggest limitation is that you cannot run 240V and 120V outputs simultaneously. If you need both at once, that may constrain what you can power.
General Sentiment - Based on Reviews and Reddit
We scoured reviews and threads to gather what people love and dislike about these units. The overall impression is that these are both great units and its hard to go wrong with either.
Anker Solix F3800
-
Overall vibe: Powerful, premium, impressive build; people see it as a beast for home backup or serious off-grid setups. But also many treat it more like a fixed station than something mobile.
-
What people consistently love: Big output, strong solar recharge, expandability, LiFePO₄ reliability. Many say “if I want something to handle everything, this is it.”
-
What people consistently gripe about: The size / weight; reliability glitches (random shutoffs, support issues); the cost; limitations on solar input voltage; the app not telling much in historical usage or warning edges.
EcoFlow Delta Pro 3
-
Overall vibe: Seen as more rugged, slightly more mature in its path (with better weather resistance, nicer app and accessories). Many users feel it’s more “road-tested.”
-
What people consistently love: Robust performance under load, good features like pass-through, multiple charge options, compatibility with past EcoFlow gear. Users also praise the long battery life and the ability to use it as a serious backup during outages.
-
What people consistently gripe about: Cost, the weight / bulk, occasional reliability / firmware bugs, accessory / adapter issues, the limitation on simultaneously using 240V and 120V outputs, and sometimes slow customer service particularly for big units.
Verdict
Both of these are amazing units and what might work best for you may not be the best choice for the next person. As much as we hate not giving solid recommendations, we know everyone’s experience and situations are unique.
If you require the higher watt rating and also need to use the 120V and 240V outputs at once, need a 50 amp plug, and want more room for expansion, the Anker SOLIX F3800 is the clear choice.
If you are going to use the power station in a less than ideal environment and you already own Ecoflow products, or need a native 30 amp plug, then the EcoFlow Delta Pro 3 might be the safer/better bet.
