Specifications
Last checked on 10 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 288 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. | Not stated. Anker's page says 'a decade' of power from LFP cells, with no cycle count |
| ExpansionExtra battery units that add storage to the same system. | Not stated |
| 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. | 300 W. The UK page does not give the number of AC outlets (7 charging ports in total); Anker's US page lists 3 AC outlets for the 120 V model |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 600 W ('SurgePad') |
| USB-APorts for phones, tablets and small devices. | 1 port, 12 W (US page) |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 2 ports, 140 W two-way each (UK page); the US page also lists a 140 W + 140 W output set |
| Car outletA 12 V socket like the one in a car, for car accessories. | 1 outlet, 120 W (US page) |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 330 W (US page, 120 V model) |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | 80% in 50 minutes |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 100 W max, XT60 connector, up to 28 V (US page) |
| 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. | 1 x 140 W USB-C or the car socket; no time given for the UK model |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | Not stated |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | About 165 × 160 × 241 mm (6.5 × 6.3 × 9.5 in, from Anker's US page; Anker does not say which number is which axis, and the UK page gives no size) |
| WeightMatters for lifting, wall mounting and moving it. | About 4.1 kg (9.1 lb, US page) |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not stated |
| Noise levelFan noise while working. | 25 dB at 1 m |
| 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 |

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.

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.

Where this information comes from
We have not tested the C300. The AC model C300 (A1722) is described by Anker's UK product page; sizes, weight and port details come from Anker's US comparison page, which lists the 120 V version, last checked on 10 November 2026. The C300 DC (A1726) is a different, DC-only model and is not covered here. A value that Anker does not state is shown as not stated.
We do not show prices, because they change often and differ between sellers.

Common questions about Anker SOLIX C300
What can the Anker SOLIX C300 run?
It is rated at 300 W continuous with a 600 W surge, so laptops, routers, lights and small fans are fine; a kettle is not. Divide 288 Wh by the device's draw for a rough running time.
What is the difference between the C300 and the C300 DC?
The C300 has AC outlets and a 300 W AC output. The C300 DC is a DC-only model without AC outlets. This page covers the C300.
Is the Anker SOLIX C300 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.
