Steve Manc Posted March 14, 2023 Report Share Posted March 14, 2023 At home we use electric toothbrush ( battery operated ). In the past we have tried to charge one on the boat on 240 supply and it stopped working. I recently contacted the toothbrush manufacturer who said they cannot be charged via battery as per the boat. It some how damages the toothbrush. Is anyone using a battery operated toothbrush on there boat and charging it off the batteries? If so what is the make and model?

haggis Posted March 14, 2023 Report Share Posted March 14, 2023 We use Braun Oral B electric tooth brushes and we charge them on the boats 240 power supply when we are cruising and have the invertor running ( we tend to just have the invertor on when we need 240 for something) . We have been doing this for years with no problems. Link to comment Share on other sites More sharing options...
Rob-M Posted March 14, 2023 Report Share Posted March 14, 2023 Mrs-M does the same as Haggis, charges toothbrush whilst we are cruising via inverter. I think it is also an Oral B toothbrush. Link to comment Share on other sites More sharing options...
philjw Posted March 14, 2023 Report Share Posted March 14, 2023 some types can be charged by a USB adapte, others have this built into the case https://www.amazon.co.uk/Toothbrush-Charger-Inductive-Electric-Chargers/dp/B08DKJQW76 Link to comment Share on other sites More sharing options...
David Mack Posted March 14, 2023 Report Share Posted March 14, 2023 Sounds like the usual incompatibility between some inverter 240V output waveforms and some electronic appliances. Some items work together, some don't, although the chances of success are higher if you have a PSW inverter. Was your toothbrush permanently damaged, or is it still working OK at home? One alternative is to use an electric toothbrush powered by disposable batteries. Link to comment Share on other sites More sharing options...
ditchcrawler Posted March 14, 2023 Report Share Posted March 14, 2023 Have charged mine for the past 10 years plus the grand kids tooth brushes when they come on board but I do have a Mastervolt True Sine invertor, what is generating your AC? This could be your way out if your AC is poor 1 Link to comment Share on other sites More sharing options...

Exactly this ^^^^^ It was well known that so called modified sine wave inverters had a habit of destroying such things, and I would not be confident that a "no name" far eastern pure sine wave inverter would avoid the issue. If the OP has a pure sine wave inverter, the load from the toothbrush may well not be high enough to make it turn on, especially if it still works at home.

doratheexplorer Posted March 14, 2023 Report Share Posted March 14, 2023 I used to a a MSW inverter. It killed my electric toothbrush. I now have a PSW inverter and have no problems charging my toothbrush. I suspect you have a cheap MSW inverter. Link to comment Share on other sites More sharing options...

With another charger, which doesn't have to be on the boat, though my inverter so far plays nice with everything. Plus the brush can run weeks on one set of rechargeable AA's. The brushes that sit on a charger when not in use have less capacity and so really need to work with the inverter. Link to comment Share on other sites More sharing options...
haggis Posted March 14, 2023 Report Share Posted March 14, 2023 Ours work for weeks after charging and we don't need to put them back on the charger after every use.. Link to comment Share on other sites More sharing options...

Made by oral-b/braun, but no model numbers on it. Their web site is too hard to navigate and directs you to the most expensive, magic pixie dust powered ones all the time, not the cheap replaceable battery brushes.

This could be your way out if your AC is poor Having destroyed several toothbrushes on different (cheapo) inverters this is what I use now too. If the inverters a good un I use my mains phone charger and if not I use my 12v phone charger. Never had a problem since.

Bacchus Posted March 14, 2023 Report Share Posted March 14, 2023 Manual toothbrushes are SO inferior that they should carry a government health warning that they are only to be used when the electrickical one has failed Link to comment Share on other sites More sharing options...
