Does what I need it to.
Bought to expand the battery capability of a Seestar S50 telescope, and use in emergencies. For the price the quality and facilities were exactly what I needed. It works as expected (use one of the top standard usb sockets for this - the usb only charges the device itself. ) I haven’t tried the 240v socket on it yet, and we’ve had no power outages since purchasing so I can’t comment on its use for this. But I’m happy with mine.

It’s okay for devices which use low power.
Firstly, this is not a heavy duty device. Powering around 20 watts of output using approx 12% of battery per hour. I bought this due to a planned power outage at home and needed my fish tank filters to have power. It has done okay. 100% charge down to 2% seven hours later. Decent enough product but wouldn’t want to be trying to use any device which needs a lot of juice.

Great for short camping trips / weekends away
The media could not be loaded. Really happy with it so far. Looks like it should give me 36-48 hours of use of my mini fridge freezer. If you need to power a dc device then you’ll get far better power usage on dc vs ac, so it’s a shame it doesn’t come with a dc out cable (you do get a dc in for car charging) especially considering there isn’t a cigarette lighter socket, but they’re pretty cheap to get hold of adaptors online. I haven’t noticed any heat issues, and I’m very glad I didn’t stump for a larger battery, as I can imagine lugging this around would be a pain if you’re going too far - I’d hate to think what a 500wh would be like. If you’re not venturing far from the car you’ll be fine. Vtoman seems like a fairly reputable brand, and I’m glad I got a refurbed one of these vs the hundreds of cheap ones on eBay that I fear would set my house on fire. LiFePO4 seems like pretty decent battery technology so far.
