Is it energetically viable to use a mobile wifi hotspot exclusively through USB connection?

I found this suspiciously cheap unlocked ZTE MF910V in my internet provider's webshop(10% more expensive than the cheapest 4G USB dongle ZTE MF831, wonder why is that so - USB 3.1 type C introduction?) which i would use almost exclusively on my desktop PC via the USB connection but i read this in the manual:

"During periods of high continuous activity with multiple users, high download rates or low network signal, charging by USB will not have sufficient current to charge the device. In this situation the battery will discharge so it is preferable to use the mains charger" and "Under poor network conditions the modem transmits at a higher power level and may get hot"

Im not sure whether the accent here is on "multiple users" or also what is the difference in energy consumption between the USB and WIFI connection to the internet but i do qualify for the high continuous activity with high download rates part, possibly with low network signal as well so i wonder if the USB charging would be enough.

The device has the possibility to shorten the range of the wifi for better power saving, not sure if it can be turned off altogether.

While im at it, regarding the 2.4/5ghz dual band thing, is there any difference in being connected to the device directly via USB or via an 5ghz wifi adapter?

I know that with my Franklin 850 USB / Wifi MiFi device, if I plug it into a PC's USB port, the battery slowly discharges, so you can't use it continuously 24/7 that way. But if I plug it into a 1A USB AC charger, the battery doesn't discharge.
