Well, this one is a good joke by itself. And you probably need a good insurance if you're going to use it. Wait a moment, got it as a feebie with the branding of a major international -- you guess it -- insurance company! 
I got two cheap power banks from this year's APEC (Applied Power Electronics Conference, the highest level of power electronics conference, with ~5000 attendees each year), branded with Linear Technology and Mouser.
Both are illegal, at least by Chinese law (Chinese law requires factory's name, contact and address be noted on product), and I bet the CE logo is a fake. There's also an FCC logo, which they don't need, plus there are no FCCID numbers.
For those events, it's more like the sponsor has no idea what freebies the guests will get, it's all operated by third party event organizers which have no tech knowledge.
And no, not every engineer knows about safety. I've seen TI videos featuring 830B meters, and I've seen a live Tek product show blowing up devices.
