A step down transformer alters the length of sine waves to create 110V current. Electronic appliances require a full wave and should therefore ONLY be used with a transformer. Electric appliances can operate with either a half wave or an altered wave and can be used with a converter OR a transformer. Transformers are for long term use while converters are not. A converter should not be used longer than is necessary to use the appliance and certainly not longer than 2 hours.
Transformers are usually much heavier than converters.
While transformers are designed for long-term use, you still should unplug them when not being used. Pte Ltd. All rights reserved.
