By: Jonny Graham | Updated August 2026 | 9 min read
If you’re packing for an overnight fishing trip, space in the car boot counts as a premium. The Anker Solix C300 DC solves this issue well. It weighs only 2.8kg and has a compact vertical shape, offering a 288Wh LiFePO4 battery designed entirely around highly efficient DC and USB power delivery.
🏆 Quick Verdict
Rating 4.7 out of 5 Stars
While it won’t power heavy duty appliances while fishing, it’s perfect for keeping your 12V camping fridge cool, and charging your devices.
Fishing With The Anker Solix C300 DC
During the hotter summer months, fishing is often slow during the day. The best times are usually late at night or first thing in the morning. If you’re a long way from home, the only practical way to make the most of these windows is to stay out overnight.
For an overnight fishing trip, the Anker Solix C300 DC capacity works well as long as you keep your expectations realistic. Here’s how it performs:
Overnight Fishing with the Anker Solix C300 DC (288Wh)
Arrive on Friday evening with a full battery and leave on Saturday morning or early afternoon.
Appliances used: 12V camping fridge, laptop, phone charging, and lights
| 12V Camping Fridge (Alpicool-style) | 13–15 W | 12–14 hours | 160–210 Wh |
| Laptop charging (60W MacBook-style) | — | 1 full charge | 50–60 Wh |
| Smartphone charging | — | 2–3 full charges | 20–30 Wh |
| LED lights / small devices | 5–10 W | 4–6 hours | 20–40 Wh |
| Total estimated consumption | — | — | ≈ 250–340 Wh |
With a full 288Wh battery, the Anker Solix C300 DC can easily handle an overnight stay if the fridge is your main continuous appliance. Most mornings, you’ll still have a bit of power left.
Pro Tip: Chill the fridge at home for 4 hours before you go. If you put warm food or drinks into a warm fridge, it can use 15 to 20% of the battery just to cool down.

Solar Top-up: 100W Panel for UK Summer
A 100W solar panel can recharge your battery during the day, even if you are only away for one night.
| Saturday morning–afternoon | 200–350 Wh | Enough to fully recharge the C300 |
| Full day (if staying longer) | 300–400 Wh | Comfortable multi-day top-up |
With good UK summer weather, a 100W panel can recharge the Anker Solix C300 DC to full or nearly full by the afternoon. This gives you useful flexibility if you decide to stay longer or want to keep your catch fresh in the fridge on the journey home.
To keep the battery charged on sunny days, use a panel that matches this limit.
Here are the two options we recommend:
- The Brand Option: The official Anker 100W Portable Solar Panel is sleek, efficient, and connects easily to the unit.
- The Budget Alternative: If you want to save money, a Renogy 100W Portable Folding Panel works well in good weather. Since third-party panels use MC4 connectors, you’ll need an MC4-to-XT60 adapter cable to connect it to the Anker unit.
(Take the guesswork out of your wiring. Use our free Solar Panel Matcher to find the exact panels and adapter cables you need to get your Solix C300 running smoothly off-grid.)
Honest Drawbacks: What the C300 Cannot Run
The Anker Solix C300 DC is made for 12V camping gear and personal electronics. It cannot run heating appliances.
You cannot use a 230V travel kettle, camping toaster, small microwave, or hair dryer. When cooking use a gas stove for your morning coffee and save the power station for your fridge and electronics.
The tall, vertical design saves space in a packed car boot, but it also means the unit has a higher centre of gravity. If you pull a charging cable too hard on uneven ground, it can tip over more easily than a flat-base unit.
What Are The Pros & Cons of the Anker Solix C300 DC?
Pros:
- Ultra-Fast Recharging: With a standard adapter connected to a wall socket, the battery charges to 80% in 50 minutes and reaches 100% in about 70 minutes.
- Dual 140W USB-C Ports: This is great for remote workers. You can fast-charge two high-power laptops at the same time without using bulky AC adapters.
- Smart Vertical Design: The unit is about the size of a camping lantern, so it leaves plenty of space in your car boot for your tent and sleeping bags.
- Built-in Illumination: The pop-up LED light is bright and well-placed to light up a dark tent.
Cons:
- Requires Careful Power Management: With 288Wh, you’ll need a solar panel if you want to run a 12V fridge for more than one night.
- No AC Outlets: This is strictly DC-only power hub. It does not feature a traditional 3-pin UK socket, meaning you cannot plug in standard household appliances.
- Top-Heavy Build: Because of the vertical design, the unit can tip over easily if it’s on uneven ground and a charging cable gets pulled.

EcoFlow River 3 vs Anker Solix C300 DC
The Anker Solix C300 DC and the EcoFlow River 3 (which we reviewed earlier), are both small power stations made for short trips. Their main differences are in capacity, weight, and the types of ports they have.
The EcoFlow River 3 comes with a 245Wh battery and can provide 300W of continuous AC power, or up to 600W with X-Boost. It weighs around 3.55 kg and can fully charge from the mains in just 60 minutes.
It also has a standard 230V UK socket and offers IP54 water resistance, which is handy for the UK weather.
The Anker Solix C300 DC has a bigger 288Wh battery and is lighter at only 2.8 kg. Since it is DC-only, it does not have AC outlets, but it offers powerful USB-C ports, including high-power options.
This makes it great for charging phones, tablets, laptops, lights, and other USB or DC devices. It also has a built-in light.
Choose the EcoFlow River 3 if:
You need a standard 230V AC socket for small appliances and want the fastest charging time from the mains.
Choose the Anker Solix C300 DC if you want the lightest option, a bit more battery capacity, and mostly need to charge phones, laptops, and other USB or 12V DC devices.
Final Thoughts
The Anker Solix C300 is a well-designed, purpose-built device. By leaving out the heavy inverters found in 1000Wh units, Anker made a very portable 288Wh hub just for overnight campers.
As long as you know its limits, especially that it won’t boil water, it’s a great choice for keeping your camping fridge cold overnight and making sure your essential tech stays charged off-grid.
Anker Solix C300 DC FAQ
What size of power station do I need? Is the Anker Solix C300 DC the right size for me
The Anker Solix C300 (288Wh) is great for short camping trips, charging laptops, and running a 12V fridge overnight. If you want to use heating appliances or camp off-grid for a week you’ll need a bigger unit. Use our free Camping Calculator to get a recommendation based on your daily needs.
Can the Anker Solix C300 DC run a kettle or microwave?
No. There are no 3 pin sockets sockets to plug them into, instead it provides powerful USB-C ports instead for laptops and iphones, plus 12V appliances (like camping fridges) only.
What is the maximum solar input for the Anker Solix C300 DC?
The unit takes up to 100W of solar input and works with voltages from 11V to 28V. Using a bigger panel won’t charge it faster because the controller limits the draw to 100W
Can I use third-party solar panels like Renogy with the Anker Solix C300 DC?
Yes. As long as the third-party panel’s Open Circuit Voltage (VOC) is under 28V, it will work fine. You’ll need a standard MC4-to-XT60 adapter cable to connect the solar panel to the power station.
