You'd think in the 21st century people would understand the basics of something so fundamental to nearly everything... electricity. New readers use a micro-USB connector, USB, of whatever size, is a 5 volt standard... if you are using a PSU with a USB connector then you have the right voltage.

Current (amperage) used is determined by the device and the PSU... the device tries to take what it needs and the PSU supplies up to that amount. The basic USB standard is 500mA and the PSU should supply that but for power it can be higher. The readers are happy to daw up to 1500-2,000mA if available (and will correspondingly charge more quickly) but only if it is available... it won't take 1500mA from a PSU rated at 1000mA, it'll try initially and recognise that it isn't available and settle down at 1000mA.
PSU should also be active as far as USB is concerned.

ANy USB active PSU rated at 500-2000mA with a micro-USB connector is fine and your 350-950 will thank you...
