| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 3,840 Wh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP (lithium iron phosphate) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | 3,000 cycles, with at least 80% capacity remaining |
| ExpansionExtra battery units that add storage to the same system. | Up to six expansion batteries, for up to 26,880 Wh in total |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 6,000 W. The UK page does not give the voltage; its FAQ mentions 120 V and 240 V ports. |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | Not stated |
| USB-APorts for phones, tablets and small devices. | Not stated |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | Not stated |
| Car outletA 12 V socket like the one in a car, for car accessories. | Not stated. Anker says the F3800 has built-in RV ports and an EV port of 3,000 W. |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | Not stated |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | Not stated |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 2,400 W, XT-60 connector, 11-60 V: up to 10 A at 11-32 V and up to 25 A at 32-60 V |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | Not stated |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | Not stated |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | Anker's FAQ mentions a UPS mode in which only the three ports labelled UPS work; no switchover time is given |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | Not stated |
| WeightMatters for lifting, wall mounting and moving it. | Not stated |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not stated |
| Noise levelFan noise while working. | Not stated |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not stated |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 5 years. Anker says its InfiniPower technology is designed to last 10 years. |
How long will it run your devices?
Choose how many of each device you want to run at the same time. The wattages are typical figures, so check the label on your own devices.

The estimate assumes 85% of the rated capacity is usable after conversion losses. Anker SOLIX does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.

- Not compatible: The F3800 Plus is a different model that Anker's site shows only for North America (designed for North American power standards). This page covers the F3800.
Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.
Strengths and things to check
Strengths
- 6,000 W AC output (Anker's figure)
- 2,400 W solar input
- Expandable to 26,880 Wh with up to six batteries
- 3,000 cycles to 80% capacity
- 5-year warranty
Worth checking before you buy
- Anker's UK page showed it as sold out on 10 November 2026
- The UK page gives no dimensions, weight, noise or protection rating
- The UK page's FAQ refers to 120 V ports, so some of its content may describe the North American version
- Not a home battery: do not connect it to your home circuits in a way that lets it feed the house

Common questions about Anker SOLIX F3800
What can the Anker SOLIX F3800 run?
It is rated at 6,000 W AC output, which Anker says is enough for appliances such as a dryer. Divide 3,840 Wh by the load in watts for a rough running time; real times are shorter because of conversion losses.
What is the difference between the F3800 and the F3800 Plus?
They are two models. Anker's site lists the F3800 Plus only for North American power standards. This page covers the F3800, which Anker lists on its UK site.
Is the Anker SOLIX F3800 the same as a home battery?
No. It is a portable power station that you plug devices into. An installed home battery is wired into your electrics by an electrician. See our guide to plug-in and installed home batteries.
