How to choose a transformer that is right for your purpose.

        Step down transformers are basically for use overseas. They will step household 220/240 Volts AC down to 110/120 Volts. Step up transformers are for use in the USA. They will take household 110/120 Volts AC that we have here and step it up to 220/240 volts. Style A models that we offer are only step down models. Style B offers the capability of stepping voltage UP or DOWN all by switching a button on the back of the transformer. Style B models also offer a housing for the transformer so you will not feel the warmth generated by the transformer. They also have multiple outlets and an ON/OFF switch for added convenience. Both style A and B transformers are continuous use models. Style C models are similar to style B and are also for continuous use. The Style C models are best quality transformers. They also have a voltage meter and a robust heavy duty continuous use transformer built-into to the best quality housing. Style D is the same as the style C plus it has a voltage regulator to output a clean spike free voltage source. This model is perfect for sensitive equipment like; TVs, VCRs, DVDs, Computers, Printers, AV Equipment......

        Remember to leave at least a 100% slack for the transformer. Using them to maximum capacity will eventually burn the transformer out after prolonged use. Some items, such a laser printers, microwaves and power tools, spike when you turn them on. For these types of situations you need to buy a transformer that is at least twice or thrice the items capacity.
