The universal power supply offers the possibility to operate a variety of small electrical devices such as pocket computers, digital cameras, measuring instruments, MP-3 players, CD players, etc..
Included in delivery is an 8-piece plug set to connect the many different devices with the matching plug. The polarity can be adjusted by turning the adapter plugs. The output voltage can be set on the rear of the power supply using a rotary switch.
Excellent product and much cheaper than many Branded Names of P.S.U. My high marks for this product is due to the fact that I can use it on many different gadgets that require different Voltage, etc. Whereas when you buy a Branded P.S.U for use with an instrument, or piece of equipment of the same Brand, you can only use it on that Instrument-Voltage requirement. So, with this versatility of Voltages, I can say I got myself a good deal by buying this 'Music Store' Brand P.S.U.
