Please note:

> These power supplies work exceptionally well but DO NOT have built in cooling fans.  They do generate some heat when in use so we recommend mounting a small fan on top of the unit [such as a small 12v one found inside PCs or available from local electronics stores] 

> As with all charging equipment, use in a well ventilated area and DO NOT LEAVE IT  UNATTENDED WHILST IN USE.
