The effects from your tests present that it is definitely a reasonably large offer and will lead to some damaged electronics or simply worse, a fireplace.
But my practical experience of change-mode wall-warts is the fact a lot of of these die, Nearly invariably on account of inadequate ripple-rating of possibly the mains-aspect electrolytic capacitor or else the primary electrolytic following the secondary-facet rectifier.
No one -not on the internet- has better purchaser information Within this unique space than you might have below on this web site.
This is a superb post. Extremely valuable. I've several brick form power provides which i'm pondering converting into "usb chargers":
