SpecificationValue
Storage
CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later.288 Wh (Anker's page also gives 90,000 mAh)
Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat.Not stated on the page (the battery type is shown only as an icon)
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
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.None: the C300 DC has no AC outlets (Anker's table shows no AC output)
AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start.None
USB-APorts for phones, tablets and small devices.2 ports, 12 W each
USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops.3 ports: 2 x 140 W (USB PD 3.1) and 1 x 100 W; 300 W in total
Car outletA 12 V socket like the one in a car, for car accessories.1 outlet, 120 W
Charging
AC chargingHow fast it charges from a wall socket. Higher means a shorter wait.None: there is no AC input. It charges through USB-C, solar or the car socket
Time to charge from the mainsHow long a full charge takes from a wall socket.Not applicable. Over USB-C (2 x 140 W, 280 W in total): 80% in 60 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, 28 V
Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names.80% in 2.5 hours (Anker's figure)
Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road.Car socket: 80% in 2.5 hours (Anker's figure)
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 201 × 119 × 124 mm (7.9 × 4.7 × 4.9 in, from Anker's page, which gives the three numbers as 4.9 × 4.7 × 7.9 in without saying which axis is which)

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.Not stated on this page

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.

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.

Page published. Anker's separate UK product page for the C300 DC returned a 'page is missing' message, so every value comes from Anker's UK comparison page for the C300 DC and C300.

Where this information comes from

We have not tested the C300 DC. Every figure above comes from Anker's UK comparison page for the C300 DC and C300, last checked on 11 November 2026. Anker's separate C300 DC product page was not available that day. The AC version has its own page: see the Anker SOLIX C300. A value that the page 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 DC

What can the Anker SOLIX C300 DC run?

Only devices that charge over USB-C, USB-A or a 12 V car socket, up to 300 W in total: phones, laptops, tablets, cameras, small fans and lights. It has no AC outlets. Divide 288 Wh by the load in watts for a rough running time.

What is the difference between the C300 DC and the C300?

Both are 288 Wh. The C300 has AC outlets (300 W, 600 W surge); the C300 DC does not and is about 2.8 kg against about 4.1 kg. See our Anker SOLIX C300 page.

Is the Anker SOLIX C300 DC the same as a home battery?

No. It is a small 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.
