WHY IT
Small, DC-only power.
Built on LFP cells.
The C300 DC is Anker’s compact power station without AC sockets: USB-C, USB-A and a 12V car outlet, from a 288Wh battery.
Recharge from USB-C, solar or the car
Anker says it reaches 80% in about an hour with both PD 3.1 USB-C ports on 140W chargers (280W total). It also takes up to 100W of solar through its XT60 input, or 12V from your car.
LFP cells, five-year warranty
Anker lists LFP battery chemistry rated for 3,000+ cycles to 80%, and a 5-year warranty.
CHECK THE FIT
What it suits.
And what it doesn’t.
Starlink Mini: use the 12V outlet
Its 12V car outlet gives 12V⎓10A, above the Mini’s 60W input rating, so a 12V Mini cable runs the dish. Anker lists a 140W USB-C port but doesn’t state 20V/5A, which the Mini needs over USB-C, so the 12V outlet is the sure option.
No AC sockets
This is the DC-only C300. Anything that needs a 230V plug, including Starlink Standard’s power supply, needs a model with AC outlets.
Solar panels: XT60, 11–28V
Anker says to use panels between 11 and 28V with an XT60 connector, and recommends its 100W or 60W panels. It isn’t compatible with the Anker SOLIX PS30 (or other 5V/3A USB-C panels), PS200 or PS400.
Charge it before first use
Anker says to activate it with an 18W or higher USB-C wall charger on the USB-C2 or USB-C3 port.

WHAT IT HAS
The ports.
And what comes with it.
USB-C
Anker’s spec table lists USB-C outputs of 1× 100W, 1× 140W and 1× 15W. Its feature text describes two 140W two-way USB-C fast-charging ports.
USB-A and the low-power ports
Two USB-A ports at 12W each. Used together, the USB-A and USB-C4 ports give up to 20W in total.
App connection
Wi-Fi and Bluetooth, with Anker’s mobile app.
In the box
The power station, a USB-C to C charging cable, a safety manual and warranty information. A carry strap is sold separately.
WORKS WITH YOUR STARLINK
Starlink run time.
From the maker’s figures.
How long the Anker SOLIX C300 DC (288Wh) would run a Starlink Mini, worked out with the Starlink power bank calculator from Starlink’s published averages and Anker’s own specs.
Starlink Mini · USB-C
Not confirmed
The maker lists 100W USB-C but doesn’t state 20V/5A, which Starlink Mini needs. To be sure, use the 12V outlet.
Starlink Mini · 12V outlet
About 8 hours 40 minutes
6 hours 30 minutes (heavy use) to 13 hours (light use)
A theoretical estimate at typical use, not a guarantee: Starlink Mini averages 20–40W, according to Starlink; we assume 85% of the battery’s energy reaches the dish by USB-C or AC and 90% from a 12V outlet. Figures checked 6 October 2026 (Anker product page ↗).
