12 volt to 8.5 volt DC Converter for operating Slim Playstation-2 in a Car or boat

12 volt dc to dc converter regulator High power 12 volt to 8.5 volt, DC/DC Buck-Boost converters at low cost. Suitable for operating PST2 playstations with 8.5 volt input in cars, boats, busses and motorhomes. This power adapter is appropriate for the operation of the PS2 SCPH-70011 and SCPH-70012 from a 12 volt source such as a car or boat. These playstations require 8.5VDC to operate. Other versions of the Playstation™2 require other AC or DC voltages

. It is possible to use the Playstation2 slim in a car in several ways. Our PST-DC128.5-11 is the premier way to do it, since it supplies superbly regulated 8.5 volts, filters noise and spikes from the car's electrical system, and is highly efficient. You can also use an DC/AC inverter, but these often cause noise in the video, audio, and/or car radio due to the modified sine wave output. There are also linear regulators available which are inefficient (they put out up to 55 watts of heat) and don't have the same degree of isolation from noise, spikes and ground loops.
Motors: Running motors from these units will void the warranty.
