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.

Just a bit above the $120 Costco price, though it also included a free 100W USB-C charger.

I've had this for two years. I originally bought it to power a CPAP when camping but its far more useful than that. It's great on road trips to power the kids' electronics keeping my charger free up front. I can also charge my laptop, and I've found this power bank to be easier to use than finding the laptop charger and an outlet, plus I can be anywhere in the house or patio with laptop and power bank and not worry about where an outlet is.

Do you not have USBC wall power bricks??? How do you charge your USBC devices at home?

The only reason that you use AC is to charge it at high speed but with 3 lb added weight. Honestly I think the $109 deal a few weeks back for the DC version from costco is the best. with only 300w maximum output, dont even think about powering up your microwave, toaster, etc. this is just large power bank for your laptop, smartphones, tablets, etc.

This is a 100 Watt charger and is fast charger. Well worth $40 to $50 alone.

As of this morning, it's currently on sale at Costco again for $120 including the charging brick. I just picked one up from there.
