Blu-ray/DVD player on RV 12 volts?

[RVhiker]

I bought a Sony BDP-S1700 Blu-ray/DVD player for our RV. It is powered by a wall wart supplying 12 volt DC. Could it operate without damage powered directly from my RV 12 volt system, which at times is actually 14.3 volts?

its a DC buck power supply, its a circuit board with components to regulate the voltage to 'your' set point

most are adjustable over a wide range, like 12v-40v in
and 5v-30v out

there are BUCK only
Boost only,
and buck/boost, which can do both functions
say power fluctuates 10v-15v and you want to maintain 12v
then use a buck/boost module

Drock is one brand, well know, good quality,

I've got two meters. The ancient Micronta digital (I bought it way before I got grey hair) says 12.51 volts. The newer Craftsman meter says 12.3. Both under no load, of course.

What DC voltage (metered) is the wall wart actually outputing?

Maybe. Depends on the DVD power input circuit. If it designed to take more than 12 volts it should be okay. It costs a little to make the power input tolerant of higher voltages and who knows what they did.

Get a Buck transformer off of e-bay to protect your blu-ray player.
