* AC powering and charging fuction, Interchangeable tips which eliminates the need for multiple adapters, Interchangeable notebook tips at 15,16,19 & 24V DC, Standard wall outlet, Status light to indicate functionsVoltage Converter Transformers- is one of the largest distributors of world-class consumer electronic goods including voltage transformers, voltage converters, and voltage stabilizers, Plug Adapters etc.These are heavy-duty continuous use transformers for worldwide use. These Transformers are for converting 220V/240V to 110V/120V and vice versa. These are referred to as STEP UP/DOWN transformers, step up/down voltage converters, 110/220V voltage converters, and 220V to 110V power converters. These transformers can only be used to convert Single Phase 220/240V power to 110/120V or vice versa. Ideal for use with 220/240V products in the USA or with 110/120V products in foreign countries. TRANSFORMER PURCHASE GUIDE: Remember to leave at least a 100% slack for the transformer. For the TVs, the power surge margin is 5 times the wattage of the TV. Heating appliances, laser printers and power tools spike when you turn them on. For these products you need to buy a transformer that is at least 3 times the items capacityThese voltage stabilizers can be used for converting the 110/120V to 220V/240V or vice versa. Or these can be used just for regulating 110V or 220/240V power. Also known as regulator, voltage stabilizer, voltage stabilizers, dual voltage stabilizers, dual voltage converters. Ideal for use in countries where there is a lot of fluctuation in the power. Protects your equipment from damage due to power fluctuation.
