Well, this is a bit of an ecologic disaster. It's another singe-use product that seems to contain a fully rechargeable lithium cell.
I can understand why they did it, since lithium ion cells have a very high energy density and are cheap to mass produce, but it still seems a terrible thing to make a disposable item that could be reused 1000 times if it had been designed around a standard power bank chip and fitted with a recharge socket.
On a plus note, for people like us it's a handy source of a decent capacity lithium cell for a low price on the high street. Note that this cell will be a typical low current cell and is not recommended for use in a high current drain application like a drone.
I have recharged the cell in one of these units completely without incident and believe them to be standard rechargeable cells, but as it's not specifically sold as being rechargeable the usual precautions should be taken when experimenting with lithium cells. the cell is bare and would require external overcharge protection.
It's interesting to note that the original manufacturer of these (Hopepower) also does a dual connector version that suits both Apple and Android devices, and does a very similar rechargeable version.

Usb-A chargers are not a bad idea. Its still a heavily used standard so it can be much more useful over a USBC adapter. There are plenty of A to C cables out there. Not to mention the image you linked also has a C port.
As for using them to deliver malware,size is not much of an issue as they can cram exploits into the cables now.
No the adapter I linked is A because the power charge is not done on the above C device, nice try anyway. The C port there is normal 5-15W which is often what you get if manufacturer does not include an real adapter solution, because those adapters are expensive. Also the reason why people complain about different charging times.
The point is that you can easier add and manipulate devices if there is more room available without that anyone will notice, it is much easier to open a big case add your stuff and glue it together.
