Portable power stations are getting smarter and more compact every year, and Anker’s SOLIX C300 is one of the most balanced options yet. It’s lightweight, powerful, and built around the same reliability that’s made Anker a go-to brand for charging tech.
Whether you’re camping, traveling, or prepping for a blackout, this little box packs way more power than its size suggests.
Design & Build
The Anker SOLIX C300 keeps things clean and modern: matte gray finish, simple LED interface, and curved corners that give it a premium feel. It’s 15% smaller than similar 300W stations, making it super easy to pack in a car, tent, or emergency kit.
It weighs just right, light enough to carry, solid enough to feel durable. And if you grab the optional strap, it becomes the most travel-friendly power station in its class.
Power & Ports 🔌
Don’t let the size fool you. The SOLIX C300 delivers 300W of continuous power (and 600W surge) from its 288Wh LiFePO₄ battery. That’s enough to run a mini fridge, laptop, camera gear, or a small fan with room to spare.
You also get 8 ports for powering everything at once:
- 3 × AC outlets (300W)
- 1 × car socket (120W)
- 2 × USB-C ports (140W + 15W)
- 1 × USB-A (12W)
That 140W USB-C port is a highlight. It supports two-way fast charging, meaning you can charge the station itself or power high-demand devices like a MacBook Pro directly.
Ultra-Fast Charging ⚡
Anker nailed the charging speed here. The SOLIX C300 can go from 0 to 80% in just 50 minutes using a wall outlet, or hit 100% in about 1.5 hours total.
And you’ve got multiple recharge options:
- AC wall charging (fastest)
- USB-C PD 3.1
- Solar panels (100W or 60W Anker panels recommended)
- Car charging on the go
So whether you’re on a road trip or living off-grid, you’ve got options.
Built to Last 🧱
The C300 uses LiFePO₄ batteries, the same long-life tech found in Tesla Powerwalls. You get over 3,000 charge cycles, meaning this power station should easily last 10 years of regular use.
It also runs quiet, just 25dB, basically softer than a whisper. And with smart temperature control and impact resistance, it’s as safe as it is reliable.
Solar-Ready for the Future ☀️
Pair it with an Anker 100W or 60W solar panel, and the SOLIX C300 turns into a compact solar generator. It’s not compatible with lower-voltage panels like the PS30 or PS400, but with the right setup, it’s ideal for long camping trips or full-time van life.
Real-World Use
Here’s what you can realistically expect:
- Charge a MacBook Pro 16” about 4–5 times
- Keep a mini fridge running for ~6 hours
- Power LED lights, phones, tablets, and drones all at once
- Recharge anywhere — home, car, or sunlight
It’s a small, quiet, reliable power source that fits into nearly any scenario.
Should You Buy It?
If you want a lightweight, ultra-fast-charging power station that’s smart, quiet, and built to last, the Anker SOLIX C300 is one of the best in its class.
It’s ideal for travelers, campers, or anyone who wants backup power that’s both powerful and portable.
