I’ve actually gotten a lot more use from this than I thought. It’s great for powering things where an outlet isn’t convenient, like using corded power tools outside.
It lasts a long time and I love that it shows charge status and how much time is left.
During dialysis most ppl shiver. They won't let you connect AC devices to their outlets. But if you bring your own powerbank, that's different story.
Solix C300 has enough charge for heated blanket for 3 hours, which will leave it with 20% state of charge. So what you do is delay the start to 1st hour, and then go full power. Anker SOLIX C1000 would prevent you from having to power budget, and I may upgrade to it, but C300 does it's job too if you like to tinker a little.
The device is ultra quiet and no fans turned on me with explained use. Never felt any heat from it either.

Thank You Anker!!!
You can charge with USB c or solar, but not both at the same time. Solar input is via xt60. There are plenty of xt60 to MC4 cables on Amazon you can use to pair to a solar panel with MC4 outputs. MC4 is very commonly a feature on portable solar panels.
You need to know that this isn't a high power high capacity power station at 288 wh capacity. It's an entry level model that will power phones, laptops, and low power electronics like lamps and fans in a power outage. I use mine to charge my hearing aids while camping among many other things. That said, this is a phenomenal offering in this category. I own ecoflow, bluetti, and Anker power stations of all kinds. I really do prefer Anker's build quality overall, though the others are frequently more wh/$ of storage. If you can grab this on sale for $200 or less, it's a great buy and a great gift!
That said, the capacity is limited, so you won’t be running power-hungry devices for long. But to be fair, that’s expected for something this small. It’s great for charging phones, small electronics, and even a laptop, but if you need extended power for larger devices, you might want to look at a bigger model.
✅ Pros:
Fast charging—gets back to full power quickly
Extremely portable and easy to carry
Good for phones, laptops, and small devices
❌ Cons:
Limited capacity—won’t power large appliances for long
Best suited for light, short-term use
If you need a compact, fast-charging power station for small devices, this is a great choice. Just know its limits—it’s not meant to power everything, but for its size, it does exactly what it should.
What I liked about the system is it that it charges the whole thing in about an hour. You have no idea how important having an AC charger is for a portable power station.
There are other power stations out there that are charged by a USB-C cord. They will take three times as long to fully charge andand you might need two cords.
I don’t have a place to live right now. I also don’t have I don’t have three hours to wait to charge any power station, or electric device in the world. This works for me. The other day it charged from 3% to 100% in less than 57 minutes. I wouldn’t say everybody needs to charge their power station in an hour but if you use it for the next 72 then I think it’s worth it. And that’s about how long I have to charge once every three days give or take.
Not everything is perfect in this world like the USB-C method. Yeah it’s fast and convenient but if you’re making a right term and you’re charging something and all of a sudden you have to come to complete stop USB-C cord isn’t going to be very happy.
So my issue was one of the ports stopped working because of my own idiotic life. But there’s still two ports left. I have an idea for a resign, but I don’t work for anchor but if I did, I would take out the two AC ports, but leave one to charge And one of course for an outlet and add two more USB ports, but we’ve got to find a way to stop them from ripping out and ruining the port
I wish I was technology that’s not even a thing, but you know how gas station pumps have breakaway hoses something like that.
What I struggle with is USB-C technology. It’s fast and convenient, but those chords and plugs rip out a lot of times ruining the port and ruining the cable where they get stepped on or water or iced tea gets in there by accident. Regardless, this is a great product and I just thinkthink the technology needs to change,
Beyond the product, which is a great price and a lot of power, the customer service support at Anker is one of the best. I’m not being paid anything to write this. I wish I was cause I could make it really sound good but I don’t need to.
Anker is probably one of the best if not the best in chargers, cables, power stations, and I’m in need of a Bluetooth speaker now so maybe they’re the best in that department too.
When you have an excellent product and a helpful and knowledgeable customer service department, you earn a five star review on Amazon and a customer for the rest of their life.
Worth Every Penny:
For what it offers, I think the Solix C300 is totally worth the price. Anker is known for making quality stuff, and this power station lives up to that reputation. It’s reliable, easy to use, and just plain convenient.
Small But Mighty:
The Solix C300 might be the smaller sibling of the C1000, but don’t underestimate it. This thing is way more powerful than Anker’s 250W power bank, giving you a significant boost in capacity and versatility. This little buddy power’s small appliances with ease. What really sets it apart are the dual 140W USB-C ports, which are a game-changer for charging speed and convenience, it’s like having a mini power station without the bulk.
Quick to Recharge:
One of the things I really appreciate is how fast it charges. Whether I’m plugging it into the wall or using USB-C, it juices up quicker than I expected. I got it fully recharged in just about an hour(with wall charger), which is great when you’re on the go.
Easy to Use:
The display is clear and gives you all the info you need, like how much battery is left and what’s being powered. The built-in LED light, has come in handy more than once, especially when the sun goes down.
Final Thoughts:
If you’re looking for a portable power station that’s powerful yet easy to take with you, the Anker Solix C300 is a fantastic choice. I hope this review helps you see if this little buddy is for you.
