Choetech 6 port 50W charger observations and questions

I got one of these impressive value for money multi-port usb chargers recently after reading multiple reviews. While i can’t say that it will put out 2 amps from each port simultaneously until more of those usb testers arrive, it is providing the promised 2 amps to my xiaomi powerbank, so that gets a thumb up from me.

Just something unusual about it is that when i move the charger, amp output immediately drops, as much as to near 0. No idea if anyone else has observed this, or knows if this is something to be concerned about?

The body of the charger feels nice, has a slight rubbery grip to it, comes with a mount that fits length-wise and has an adhesive tape to mount to another surface. Of course, like some folks i don’t really like that it uses a cable, since it adds to the bulk and is a little messy, but on the brighter side i don’t see myself having to move around if ever a power point isn’t conveniently within arm’s reach.
