Questions about this item
Which output current should I choose for my device?
Select any device that draws up to 4A at 12V; the adapter will deliver exactly what the load requires up to the 48W maximum.
What does the 48W rating mean when the adapter is powering my equipment?
It is the maximum continuous power the unit can supply; your device will only draw its needed watts, so a 24W load runs normally while the adapter stays within its limit.
What does the 5.5x2.5mm jack cap in practice?
The jack fits both 5.5x2.5mm and 5.5x2.1mm sockets with centre-positive polarity, limiting use to devices that accept that connector and voltage.
