You can't. Although the shape of the phone charger and juicer plug is similar, the voltage and current of the two are different. The mobile phone charger is generally 5V, 1A voltage, and the voltage and current required by the juicer are higher, generally 220V, 5A or more. If you use a mobile phone charger to charge the juicer, it will cause the charger to overload or short circuit, and even damage the juicer or cause fire and other safety hazards. Therefore, in order to be safe, we should choose the right power adapter to charge the juicer.
