Questions about this item

Will the 9 V output handle a full day of charging the RS 175 headphones without overheating?

The adapter is rated for continuous 9 V DC output from a 100-240 V AC input and carries CE, FCC and RoHS safety certifications, so it runs cool under normal all-day use.

How much heat or fan noise does the SA103K-09 produce when left plugged in overnight?

The unit has no fan and uses a sealed switching design; it stays warm to the touch but silent during extended operation.
