Actually, it might work depending on why the device isn't booting. It only works if the device is actually sound but has an overly depleted battery.

Nexus 6 phones were notorious for the charge getting so depleted that the high power charger was unable to get the battery going again. By plugging the phone into a low power computer USB port, often those phones could be recovered. It usually took several hours, but once the battery charging icon showed up again, switching to a regular charger would get it going again. It's also a sign that you should prepare to replace the battery.
