Gordon Posted July 1, 2008 Share Posted July 1, 2008 Now here is something for you technical guys to think about. I have a small 300 Watt inverter on the boat, I use it to charge a camcorder/digital camera/lapdog mainly, all switch mode power supplies. I do however possess a rechargeable electric razor, although shaving and boating are not things that go together in my mind. Now this rechargeable razor is a very expensive high quality bit of kit, it cost Â£3.95 in the garage at Wroxham!! Having plugged it into the inverter it did not charge for long, investigation revealed the primary of the transformer had gone open circuit, maybe cos it was cheap and nasty or maybe........ What is the output frequency of an inverter, clearly mains transformers are designed for 50Hz. So the question is is my theory right and can you use equipment that incorporates a transformer with an inverter Oh and the razor I replaced the XFMR with a weed lighter plug and a 120 ohm resistor, wonderful 12v charging now Quote Link to comment Share on other sites More sharing options...
