"Transmit Current 12mA"
Seems fairly straightforward to me. Most of the table looks like it's cribbed from the ARM datasheet (stuff like RC oscillator, SPI timing, etc.), which shouldn't be a surprise; they likely have done little to nothing "new", just packaged a chip someone else made.
For power supply purposes, you can reasonably suppose it'll draw no more than twice that (i.e., 24mA), and have plenty of capacity to spare for whatever else you might plug in. Making similar allowances there too, of course.
I'm convinced *all* IoT devices are crap, so don't be surprised.
The most important thing to remember about all embedded circuitry: even if it looks like some hard coded module, chances are, there's code inside. And their code is shit. Software is one thing you can count on being bad; good, solid, bug-free code is the exception, not the rule.
I'm especially puzzled by the manufacturer's use of the F-22 Raptor's visage on their front page; are they suggesting that their products are used in defense applications as well? (If so, where are their certifications?) God help us.
