Anker SOLIX C300 DC A1726: The No-AC Power Guide

Quick answer: The Anker SOLIX C300 DC A1726 has a manufacturer-rated nominal capacity of 288 Wh and a 300 W maximum total output. Its four USB-C ports and 12 V car socket suit compatible USB/DC devices. It has no AC outlets. The capacity figure is not a promise that 288 Wh will reach your equipment after conversion losses.

This is a research-based buying guide using official specifications, not a hands-on product or runtime test.

Who it suits and who should skip it

Shortlist the C300 DC if your camping or work setup already runs on compatible USB-C devices and DC accessories, and you value several USB-C connections, an extendable light and app connectivity. Those features are documented on Anker's US product page; they do not prove that every connected device can charge at its maximum rate simultaneously.

Skip this model for equipment that requires an AC wall outlet. For a coffee maker, blender or another AC appliance, first check its required continuous and starting power, then choose an AC power station rated for that load. Simply switching to the C300 AC&DC because it has an AC socket does not establish that it can run the appliance.

The A1726 manual lists a weight of 2.8 kg. If carrying weight matters more than extra ports, app features or lighting, compare the 2.58 kg EcoFlow TRAIL 300 DC below. These are listed weights, not our measurements.

Anker SOLIX C300 DC A1726: four USB-C ports, with shared limits

Who it's for: A USB/DC setup that benefits from several charging connections, integrated lighting and app access without requiring an AC outlet.

DiagramPower-limit diagram for Anker C300 DC A1726: 300 W maximum total output; USB-C1 100 W, C2 and C3 up to 140 W each, car socket 120 W, and USB-A1, USB-A2 and USB-C4 sharing 20 W.

Original editorial diagram, not a product photograph or load test. Ratings are manufacturer limits, not simultaneous guaranteed outputs.

The useful distinction is the system limit versus the port limit. Adding the printed port maxima does not increase the 300 W total ceiling. The two USB-A ports and USB-C4 also share their own 20 W allowance. Check both constraints when assigning devices.

Some multiport-allocation rows in the manual appear inconsistent with the stated total ceiling. We therefore do not reproduce that table or infer port priorities. This guide does not promise a particular simultaneous allocation for every combination of devices.

Charging, upkeep and accessories

For first use, Anker's US FAQ describes a USB-C activation method: connect USB-C2 or USB-C3 to a PD charger supplying at least 18 W at 9 V or higher. This identifies the documented USB-C method, rather than claiming it is the only possible activation route. For ordinary charging, Anker recommends a PD charger of at least 30 W.

The manual lists combined USB-C2/C3 input up to 280 W. That is an input rating, separate from the 300 W output ceiling. High-power charging requires suitable PD chargers, devices and cables; the documented 100 W and 140 W conditions require 5 A cables.

The US package includes a USB-C cable, but not a wall charger; the shoulder strap is sold separately. Include any required charger, cable or solar accessory in your buying decision rather than comparing the power station alone.

For solar input, check the XT60 connection, 11–28 V range and 100 W maximum together. A panel's advertised wattage alone is not a compatibility check or a promise of continuous charging power. The US FAQ lists PS30 / 5 V 3 A USB-C panels, PS200 and PS400 as incompatible.

One work-session calculation, with explicit assumptions

A useful estimate separates stored energy from power draw:

Estimated hours = nominal capacity (Wh) × assumed delivered-energy fraction ÷ total load (W).

For illustration only, assume 80% of the rated 288 Wh reaches already-compatible USB/DC loads, and assume a steady 45 W laptop, 10 W router and 5 W light. The total hypothetical load is 60 W.

288 Wh × 0.80 ÷ 60 W = 3.84 hours, or about 3 hours 50 minutes.

The 80% factor and all three device loads are editorial assumptions, not Anker specifications or our measurements. The nominal capacity comes from Anker's product information. Actual runtime varies with device draw, conversion losses, standby consumption and temperature.

A router is not automatically suitable for direct connection to the 12 V socket. Check its required voltage, polarity and connector, plus any necessary adapter or converter and cable ratings. The example assumes compatibility; it does not establish it for a particular router, laptop or light.

Pros and cons

Potential strengths: Four USB-C connections offer flexibility for a USB/DC setup. The extendable light and app provide features absent from the TRAIL 300 DC comparison below. Dual USB-C input supports a documented combined maximum of 280 W when the charging equipment meets the requirements.

Tradeoffs: There is no AC outlet, and the 300 W system ceiling and shared 20 W group constrain simultaneous use. The wall charger and shoulder strap add to the accessory decision. Listed port ratings and capacity do not establish measured charging speed or runtime.

Alternatives

The EcoFlow TRAIL 300 DC is a relevant alternative; this comparison excludes TRAIL 200 and TRAIL Plus 300. The figures below come from EcoFlow's official US variant table and the Anker A1726 manual.

Our buying judgment: Shortlist C300 DC for the extra USB-C connections, light and app. Compare TRAIL 300 DC if two USB-C ports meet your needs and the lower listed weight matters more. This is a feature-based judgment, not evidence that either product lasts longer, charges faster or is more durable.

Where to buy the correct version

Use the official Anker C300 DC product page to check the US model and package. The Amazon purchase button below targets the C300 DC listing associated with ASIN B0D62PMB3R.

Before ordering, confirm the selected C300 DC version, included accessories, seller and delivery conditions. Do not substitute C300 AC, C300X DC or another bundle without checking its specifications. These links are not a price, stock or delivery guarantee.

FAQ

Can the Anker SOLIX C300 DC power an AC appliance?

No AC outlet is provided. Choose an appropriately rated AC power station for equipment that needs one; the presence of an AC socket alone does not establish that an appliance's continuous and starting power requirements are covered.

How do I charge the Anker SOLIX C300 DC?

Use USB-C2 or USB-C3 for the documented USB-C charging route. The first-use PD conditions, everyday charger recommendation and cable requirements are collected in the charging section above.

Does C300 DC USB-C charging support 140 W?

USB-C2 and USB-C3 each support input/output up to 140 W with appropriate PD equipment and 5 A cables. The rating is not a promise that every connected device will draw 140 W.

How long will a C300 DC run my devices?

Estimate from the load and an explicitly assumed delivered-energy fraction, as shown above. Our 3.84-hour example is not a measured runtime or a guarantee for your equipment.

How we researched

We reviewed the official Anker product page, A1726 manual and EcoFlow TRAIL comparison, checked October 26, 2026. We did not handle the products, measure runtime, test charging speed or verify all simultaneous-port combinations.

The two illustrations are original editorial diagrams based on documented ratings and a separately labeled calculation. They illustrate published ratings and an explicitly hypothetical calculation. We have not purchased or physically tested the products.
