I gave 4 stars for quality because this amp is made 100% out of plastic; solid, hard but still plastic.This Boss Amplifier Katana-Mini power supply meets regulations and is great value given it includes electrical noise reduction and heat reduction and over voltage damage protection for your Boss Amplifier Katana-Mini. Take it the hotel or your holiday destination and ensure that you'll always have great tones on the road to practice with. The three all-analogue sounds – Clean, Crunch, and Brown – together with the on-board delay effect deliver everything you need for extended and enjoyable jam sessions. While other small, battery-power amps often severely compromise on their sound quality in favour of size, the Katana-Mini has been designed to produce big, full tone that will have plugging in and playing every chance you get.

It includes electrical noise reduction, heat reduction and over voltage damage protection for your Boss Amplifier Katana-Mini. The Katana Mini is small enough to keep at home without taking up much space or to throw in the back of your car on your next trip. All the style and flavour of a full-size amp, packed into a tiny, portable battery-powered amp, the Boss Katana-Mini seriously raises the bar for mini amps.This Ripcord cable takes the 5V from a USB port and turns it into the 9V and amperage the Boss Katana-Mini needs.
