Anker SOLIX C300 DC DC-only (no AC inverter) is a ultraportable / carry model best suited to camper. It has no sourced AC-output figure. Its data coverage is not yet sufficient for a comparable score.
Our verdict on the Anker SOLIX C300 DC DC-only (no AC inverter)
Read the DC in the name as a warning label, not a variant code. This unit has no inverter and no wall sockets of any kind, so nothing with a household plug will ever work with it — that single fact disqualifies it for most people who arrive here searching for a power station. What it actually is: a 288 Wh LiFePO4 pack built around 2 bidirectional 140 W USB-C ports totalling 280 W, weighing 2.8 kg. Judged as an oversized laptop bank rather than a power station, it is a coherent product.
- Everything you need to run charges over USB-CTwo 140 W ports handle a 16-inch laptop at full speed while a second device pulls from the other, and 280 W of simultaneous USB-C is more than most units three times this size offer.
- You want one battery that recharges from the same brick as your laptopThere is no proprietary charger to lose: it refills over USB-C PD, needing only 18 W to begin, so a single cable covers both directions and the 2.8 kg travel weight stays honest.
- Pack volume matters more than floor spaceThe 99 x 109 x 185 mm footprint is a narrow tower, not a slab, so it stands in a door pocket or a pannier where a wider 288 Wh unit would not fit.
- You expect to plug in anything with a household plugThere are 0 AC outlets and no inverter to feed them. This is not a small AC budget you might squeeze under, the way a 300 W unit is — the capability is absent entirely. The RIVER 3 supplies 300 W of pure sine wave AC through 2 sockets.
- You are preparing for an outage that has to cover appliancesA 288 Wh pack with no AC output contributes nothing to a fridge, a pump or a heater. It keeps phones and laptops alive for days, which is a real job, but it is not backup power. The DELTA 3 Max holds 2,048 Wh behind a 2,400 W inverter.
The honest limit: Removing the inverter is what buys the low mass and the narrow tower shape, and Anker made that trade deliberately. But it also removes the safety margin of being wrong about your own needs. Every other unit in our catalog lets an owner discover a use case later; this one cannot grow into anything, because the missing part is not the battery.
What our data can’t tell you: Anker publishes no cycle rating we can source for this model, so the usual LiFePO4 longevity argument rests on chemistry alone here rather than on a number. Surge capability and UPS behaviour are equally unsourced, though both are close to meaningless without an inverter. Note also that its 4.1 Trustpilot score sits against an F grade from the BBB.

How this score is computed
The BatteryRank score is computed from sourced data with a published formula — ranked by data, not lab testing. Seven sub-scores blend into a 0–100 composite, grouped into four buyer pillars. Price is deliberately not a scoring input: prices move daily, so value intelligence lives in the price section above, judged against this model's own history.
| Pillar | Built from |
|---|---|
| Power | Capacity & expansion + Output & versatility |
| Trust | Trust & reliability + Durability & longevity |
| Charging | Charging & solar |
| Livability | Portability + Quiet / livability |
Scores are cohort-relative — each model is ranked against others in its size class. Missing inputs renormalize out rather than scoring zero (a model is never penalized for a spec nobody in its class publishes), and any figure resting on a documented estimate is tagged est.
