Anker's C300X DC looks like a compact USB power station best suited for camping, car trips, and backup charging for phones, laptops, cameras, CPAPs, and small fridges. The 288Wh battery, 140W USB C output, lantern light, and pass through charging get strong real world praise, and the included 100W charger adds value at this price. The main limitation is that this DC version has no AC outlets, and the size is closer to a lantern than ultra portable. It is also too large for TSA flight limits, making it a practical off grid helper rather than a travel battery.
Common Questions (5)
Yes, for some setups. It has been used to run a BougeRV fridge for more than 24 hours, a Starlink Mini with solar support, and a 12V fridge/freezer in a work truck; thermoelectric coolers are much less efficient and may only last about 5 to 6 hours. A compressor fridge is the better match for longer runtime.
At $110, it is widely viewed as strong value for a 288Wh unit bundled with a 100W charger. The price works out to about $0.38 per Wh, and the charger alone is estimated to cost around $30 or more from reputable retailers.
It can handle several real-world loads for a weekend or longer: one user got 2 days and 2 nights of camping use, another ran a DreamStation CPAP for 4 nights without a humidifier or heated tube, and a 50W cooler is estimated at over 6 hours. Runtime depends heavily on the device and whether you use DC output instead of AC conversion.
No. This C300X is the DC version, so it has USB and 12V-style output but no AC plugs. If you need wall-outlet power or UPS-style AC backup, this model is too limited for that use case.
Yes. It has been used as a desktop USB power hub and for charging phones, tablets, MacBooks, headphones, hand warmers, fans, and toothbrushes, with pass-through charging supported. The USB-C ports can output up to 140W, which makes it practical for laptop charging and topping off multiple devices.

Although now that I'm off of Comcast and on Google Fiber, hopefully I'll not need it for that, and it will just be something to take as an travel connection if I know I'm going to be remote.
edit: Nevermind, this is the C300X DC, so no AC ports on this one. Leaving this comment up in case anyone else is wondering.
My use case is basically I pretty much power all the gears I have at home, 4 ppl in my house hold with few phones, tablets, macbooks, headphones, airpods, handwarmers, portable fans, electric tooth brushes, hand held massagers and etc. It's like a game for me that I only use these Solix batteries to charge all the chargeable devices I purchase through Slick Deals
I use tons of electricity at home by charging 3 tesla vehicles at home, so I am already paying tons for the electricity. So I decided to charge any other consumer electronic devices that I can charge thru USB C or A by using the portable battery packs like this Solix C300.
I work from home, remote work, at least 3-4 days a week and I visit coffee shops almost everyday, so I take one of the battery pack there with a 140W charger. I can basically charge the battery using the 140W which charges around 134W (input) to the battery, and I hook up 2 usb C cables from the battery which supports pass thru charging to charge my company laptop and my phone. So while I work at a cafe for about 3 - 4 hours, the battery pack is charge to full and my laptops and the phone are charged full, which makes me that I made money charging things off of a coffee shop.
I needed at least two of these battery packs for the weekend use to charge everything when I don't go to a cafe to charge. My household uses one whole battery from 100% to 0% a day. I believe this Solix C300 is equivalent to 90,000 mah capacity.
Some people say that the cost of the battery pack will cover the electricity used at home, but I just like this way better that makes me feel I earn/make money when I am charge the battery packs for free outside of my home. Well, this is just me.
