I had the impression that such chargers were not necessarily
compatible with each others' devices--that they would indicate
`quick-charge mode' by supplying a different voltage than a standard
USB port, and the USB-plug-form-factor charger world had yet to settle
on a standard for that `different voltage'. So, devices that are
mechanically compatible with a given charger of a different brand are
most likely not electrically compatible and often ignore it.
