An individual mains adaptor (or transformer) is the most popular way to run your portable keyboard instrument. Alternatively, batteries will power some models, but we don't recommend this as they can affect the performance of your keyboard's speakers and leak if they are forgotten.  

  Nearly all of the adaptors selected here are the manufacturers' recommended models for the UK market, as opposed to universal adaptors, which may offer the same voltage (9v), but very rarely have enough amperage (power) to successfully operate a keyboard.
