Unit looks clean and a quick check confirmed discharge/recharge functionality (though I didn't do any substantial discharge yet). Recharge rate isn't the quickest (up to 100W, 2-3 hours), only 1 USB-C port so less convenient if you want USB-C passthrough (cannot charge it via USB-C when that port is in use) but the included AC to DC coax.adapter will let you do that.
Then I figured we needed more power for the router and for other family members (we all use laptops and 1-2 monitors, have 3 aged UPS and don't feel like replacing the lead acid batteries that don't give much runtime), so I got the 499Wh VTOMAN FlashSpeed 600 also ($95+tax), which is over double the capacity of the FS300 for around 50% more $ (maybe I should've gotten two FS600 instead?). Curiously, the bigger FS600 doesn't recharge via USB-C but it can recharge much faster via AC (400W) or DC coax (200W). And 500Wh for ~$100 is crazy cheap.
Project Farm recently did a comparison of power stations and a VTOMAN (not the above models AFAIK) did quite well. Obviously you are taking chances with these semi-known brands (kinda like INIU and Baseus power banks).
For fun I connected the USB-C ports of the FS600 and FS300 for half an hour. The FS600 screen says outputing 103W while the FS300 says inputing 97W (and IIRC, my inline USB-C power meter got a bit warm and showed 20.?V 4.8?A 98W so it was charging).
