Personally I find that the stress of having permanently batteries is inconvenient because you rarely have on hand when you need it. So I obtained this power to solve this problem.
This power supply provides DC 12V 3: 3-4,5-6-7,5-9 and 12V, selection seffectuant with a simple slider. The maximum power is 10W, which is enough for most devices.
The power supply of the device being coaxial and the dimensions and shape of the entrance are variable power supply is provided 8 tips that should match all possible situations. The output The power supply has two pins which must be inserted at the back of the mouthpiece to use. We need the + of the output The power supply of the device matches the + to power; but as this information napparait not on the device, if it is not fed to plug must promptly return the mouthpiece and it works. Sil ny was not handling this (very simple) this device would have been perfect.
