The C300 DC is the DC-only member of Anker's C300 family. It carries the same 288 Wh LiFePO4 battery as the C300, but the maker sells it as "DC Only": there are no AC outlets and no AC charging input. That is the single most important fact on this card. Do not confuse it with the C300 or the C300X DC.
What it can and cannot power
None of the plug-in appliances in our database can be connected, because they all need an AC outlet. That rules out even small loads such as a Wi-Fi router on its wall adapter or a TV. What it does offer is DC: four USB-C ports (up to 140 W per port), two USB-A ports and a 12 V car outlet. If your device charges from USB-C or a 12 V plug, it can use this station; if it needs a wall socket, it cannot.
Recharging is also DC-only: two of the USB-C ports work as inputs at 140 W each, plus solar (up to 100 W) or a car socket. There is no wall-charger input in the spec list.
Battery life and what the maker does not publish
The spec card rates the battery for 3,000+ cycles to 80 % capacity, the same as the C300. Cycle counts are only comparable with their end-of-life threshold (how makers define cycle life).
Anker publishes no surge figure, no UPS switch-over time, no noise level and nothing on app control for this model, so the table shows these as not published. At 6.17 lb it is lighter than the C300, and the warranty is 5 years. Anker's own page listed it as sold out when the record was taken.
Add your appliances to the calculator to check your own load against the C300 DC.

Frequently asked questions
Can the C300 DC run AC appliances?
No. It has no AC outlets, so anything with a standard wall plug cannot be connected. It powers USB-C, USB-A and 12 V car-plug devices only.
Can the C300 DC run a CPAP?
Not from a wall plug, because it has no AC outlets. Whether your CPAP can run from a USB-C or 12 V source is a question for the device manufacturer — confirm with them before relying on any battery for this device.
How do you charge it without an AC input?
Through USB-C (two ports accept 140 W each), solar up to 100 W, or a 12 V car socket.
Is it LiFePO4?
Yes. Anker's spec card lists LiFePO4 and 3,000+ cycles to 80 % capacity.
