I was contemplating this but couldn't really think of many AC devices that would run off of 300w. Only things off the top of my head were DC devices like router or cable modem which you may be able to get an adapter for anyway. Something like these for example - there should be other options out there depending on barrel size:

https://www.adafruit.com/product/5450

The C300 with AC is bigger/heavier - not the end of the world but thats one of draws to these smaller packs:
9.1lb vs 6.2lb
6.5 x 6.3 x 9.5 vs 4.9 x 4.7 x 7.9

The Anker SOLIX C300 DC is a compact DC-only power station that works best as a portable battery for phones, tablets, laptops, and other 12 volt gear. Its lighter, smaller design makes it easier to carry than the AC version, and the included 100 watt USB C charger adds real value. It also fits practical uses like camping CPAPs, road trips, router or modem backup, and even a 12 volt fridge. The main limitation is the lack of AC output, so it will not run appliances like microwaves, toasters, or serve as a typical desktop UPS. A sensible pick if you want portability over outlet-style power.

Common Questions (5)

  • Costco has sold the same DC model for about $120, sometimes including the charging brick, so this Woot price is slightly higher. The Woot offer can still be attractive if you want the included 100W USB-C charger.

    StrategyFreakscoikeleonidimusempirefalls1

  • No. It is a DC-only model with no AC outputs, so it will not work as a typical UPS for a desktop or other AC-powered gear. It is better suited to direct DC loads and USB devices, and the lack of an inverter keeps it lighter.

    leonidimusmorningstar101wcs

  • Yes, the deal can include a free 100W USB-C wall charger, and the charger alone is valued at about $40 to $50. Some buyers also received a C300X package that included the 100W wall charger.

    StrategyFreakBlueSeagull1469admer

  • Yes, it can be a good fit for router/modem backup because those are DC devices and may run through the unit's DC outputs or with the right barrel adapter. It is not intended for higher-draw AC appliances, so it works best for low-power networking gear.

    wcsCharlesCCC

  • It works best as a large power bank for laptops, phones, tablets, and other DC gear. It has been used for camping CPAP, road trips, kids' electronics, a laptop, and even a 12V fridge, but it is not suitable for high-draw appliances like microwaves or toasters.

How is this a deal if Costco sells the same DC model for $120 with a 100W charger to boot?

Is it worth having this over the Anker airplane compliant powerbank? The size of this thing makes it seem unuseable for everyday use

Will this be a good network devices UPS ? (for router/modem etc.)

It's possible. You could design a USB-C trigger that outputs the DC voltage (typically 12 or 20V) that these devices pull from their power bricks. Just feed the Anker with power and believe they have a battery charging bypass once the battery hits 100% so the power goes directly to your devices

No, it's a DC only model, no AC outputs. It makes it lighter, and AC doesn't really make sense for such a small battery. For UPS function you need a bigger unit. I have a RIVER 2 Pro and like it a lot, it's a good weight/price to capacity ratio.

These are great devices. No need for an AC inverter on a device this small. Makes a lot of sense to leave it off and make it lighter. I like that it has the 12 volt so I can just plug my 12 fridge in it while traveling to camp and not have to worry about when I don't have the car running.
