The 12V socket, not the 96Wh, is the real reason to step up.
The Anker SOLIX C200 DC is a 192Wh LFP pack with three USB-C ports up to 140W, two USB-A and 100W of solar, at 4.2 lb, with no AC outlet and no car socket. The Anker SOLIX C300 DC stores 288Wh and adds a 12V car socket, a fourth USB-C port, two-port 280W USB-C recharging and a retractable light, at 6.17 lb. Neither has a wall plug or a UPS. If you only charge phones, a laptop and camera batteries, the C200 DC is the lighter box; if a 12V cooler, a CPAP on its DC cord or a car-socket device is on your list, it’s the C300 DC.
Below: what separates them with numbers, a 20-second calculator for your USB gear, seven modeled situations, a third option with AC outlets, and what a published test found.
The C300 DC costs $200 more on Anker’s last listed prices for 96Wh more, a 12V car socket, a fourth USB-C port, faster two-port USB-C recharging and a built-in light, at about 2 lb more. Neither has an AC outlet or a UPS. Anker US listed both as sold out on our October 31, 2026 check.

The five differences that decide it
The five gaps that decide the purchase, with the better spec for most buyers flagged. Both use LFP cells rated for 3,000+ cycles to 80%, take 100W of solar through XT60 at 11 to 28V, connect to the Anker app over Wi-Fi and Bluetooth, share the same temperature ranges, and have no AC outlet, no UPS and no wall charger in the box.
Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 163Wh usable on the C200 DC and 245Wh on the C300 DC. Rows are USB loads both can power; neither has an AC outlet.
Appliance for appliance, the C300 DC lasts 50% longer than the C200 DC.

The price gap, in numbers
The Anker SOLIX C300 DC costs $200 more than the Anker SOLIX C200 DC and adds 96Wh: that is $2.08 per extra Wh, against $0.78 per Wh for the C200 DC.
Prices refresh daily from Anker US.Both are rated for 3,000+ cycles to 80%. Budget a USB-C wall charger for either if you don’t own one: none is in the box, and the C300 DC needs two 140W ports for its fastest refill. Anker US listed both as sold out on October 31, 2026; the engine shows the last price it read, and prices move often.
The third option: the Anker SOLIX C300 at $429.99
Anker SOLIX C300: $429.99 today
The C300 DC’s sibling with AC outlets, and in stock at Anker US on October 31: the same 288Wh, with three 120V outlets at 300W and 600W SurgePad, two 140W and one 15W USB-C, a USB-A, a 12V car socket, a 10ms UPS and a built-in 330W charger that reaches 80% in 50 minutes, at 9.1 lb, with 5 years of warranty. It runs a router or a CPAP on its wall plug, which neither DC model can; it gives up the 100W USB-C port and a USB-A, and weighs about 3 lb more than the C300 DC. Our C300X vs C300 vs C300 DC comparison covers the whole family. See the C300 at Anker.
Seven modeled situations, worked out
Same formula as the calculator above: 85% of the rated capacity. Neither has an AC outlet, so every situation runs on USB or, on the C300 DC only, the 12V socket.
A laptop through a workday
Both power a laptop over USB-C; the C300 DC about two hours longer. The Gadgeteer kept a plugged-in M1 MacBook Pro going for several days of light use on a C300 DC.
Two laptops at once
Per Anker’s manuals, the C200 DC’s 140W and 100W ports give 100W each when used together; the C300 DC runs both 140W ports at full power, and still has a 100W port spare.
Phones on a weekend trip
Either covers a family weekend of phones. The C200 DC does it at 4.2 lb.
A 12V cooler on a camping trip
Only the C300 DC has a 12V socket. The Gadgeteer ran a 35L cooler on one for 24 hours, starting warm, and still had 23% left. The C200 DC can’t run a car-plug cooler.
CPAP, one night, on its DC cord
Anker’s C300 DC manual says it can power a CPAP; about six hours at 40W, short of a full night. The C200 DC has neither a 12V socket nor an AC outlet.
Refill from solar, each at its maximum
Same 100W input, so the smaller C200 DC fills sooner. Both stop at 28V: wire panels in parallel. Solar cables are sold separately for both.
In a backpack
The C200 DC is about 2 lb lighter and smaller. At 192Wh and 288Wh, neither fits the 100Wh carry-on limit without airline approval.
Eight more differences, the spec sheet and the box

App, UPS and smart features
Same app over Wi-Fi and Bluetooth; the Anker SOLIX C300 DC adds timers for its light and its 12V socket. Neither works as a UPS.
Neither takes an extra battery.Does it work as a UPS? Anker’s comparison table lists no UPS on the Anker SOLIX C200 DC or the Anker SOLIX C300 DC.
How fast does it recharge? Both recharge only from your own USB-C chargers or solar. The Anker SOLIX C300 DC accepts two 140W chargers at once.
How does the app connect? Both use the Anker app over Wi-Fi and Bluetooth, switched on with the IoT button.
Can you add a battery later? Neither the Anker SOLIX C200 DC nor the Anker SOLIX C300 DC takes an extra battery.
Warranty and support
Plan on 3 years for both: Anker’s US comparison table gives the Anker SOLIX C200 DC and the Anker SOLIX C300 DC 3 years, though a spec block on each page says 5.
Same cycle rating; keep proof of purchase.Subject to each brand’s warranty terms and eligibility.
Anker rates both at 3,000+ cycles to 80% capacity, about 8 years at one full cycle a day. Calendar aging and heat also reduce capacity, so read the rating as a ceiling.
- Keep the receipt: both US pages show 3 and 5 years.
- Register the unit with Anker when it arrives.
What reviewers report
We have not lab-tested these two units. Here is what one published review found, with the source, author and date for each point. Reviews of UK and EU units are flagged: those models charge from 230V outlets and have different sockets, so their charge times and outlet findings don’t carry over to US units.

Charging
- C300 DCReviewer No built-in AC charger: the reviewer had to combine two laptop bricks, reaching 88W, and wanted at least basic AC charging. The Gadgeteer, Lee Shipman, November 2024
UPS and output

Daily use and issues
- C300 DCReviewer A sticker on the car socket limits it to 100W, though the manual’s table lists 120W. The Gadgeteer, Lee Shipman, November 2024
- C300 DCReviewer The app sets a timer on the light and a separate hard timer on the car socket, and shows power per port. The Gadgeteer, Lee Shipman, November 2024
- C300 DCReviewer The retractable light draws 1 to 3W depending on the setting, per the app. The Gadgeteer, Lee Shipman, November 2024
Practical limits before you buy
- Neither has an AC outlet. A router, a lamp or a CPAP on its wall plug won’t run on either.
- No wall charger comes with either. Use your own USB-C charger; the C300 DC needs two 140W ports for its fastest refill.
- Anker US listed both as sold out on October 31, 2026.
- The C200 DC has no 12V socket. A 12V cooler or a CPAP on its DC cord needs the C300 DC.
- The C300 DC’s car socket may be limited to 100W. The Gadgeteer found a 100W sticker on it, against 120W in the manual.
- Both solar inputs stop at 28V. Wire panels in parallel, and buy the XT60 cable separately.
- Neither fits the 100Wh carry-on limit. Check with the airline before flying with either.
- C200 DC, per its US documentation: Total output is 200W; the two USB-A ports and the 15W USB-C share 20W, and the 100W and 140W USB-C ports together give 100W each.
- C200 DC, per its US documentation: Only the 140W USB-C3 port recharges it; you need your own USB-C wall charger, 18W minimum, 140W for full speed.
- C200 DC, per its US documentation: Solar input 11 to 28V, 8.2A, 100W max via XT60; not compatible with PS30, PS200 or PS400 panels; solar and car cables sold separately.
- C200 DC, per its US documentation: Must be used and stored upright; it powers off after 2 hours with outputs off and no load, adjustable in the app.
- C300 DC, per its US documentation: Only the USB-C2 and USB-C3 ports recharge it; both together accept up to 280W.
