Oral-B 12V charger?

I have an oral-b 1000 (3756), brand new, with a 220~240v charger (3757). I live on a boat and run a 110v sine wave inverter and 12vdc. Is it possible to modify the 240v charger to run on 12vdc? Trickle charging with through a 110-240v transformer or a 110v charger would be wastefull, but the 12vdc is on all the time.

I am looking for exact the same as this. Braun should make a 12-volt charger to their tooth brushes. It shouldnt be too complicated and very well possible as the battery in the handle is only below 6 volts.....!

SOURCE: my oral b rechargeable toothbrush

The plastic connecton has a coil in it, much like how a transformer is done. If you read up on how a transformer works its pretty much the same principle as it works on Induction. There is a coil and core iron in the end of the toothbrush and in the base, this creates AC current which inturn causes induction to flow through the coils and charge the battery. And about the reason why it is not charging is probably down to the battery being flat ( happens even when new ) or there is a loose connection when it was being transported.
Hope this helps.

SOURCE: need instructions for changing head

you simply remove your old head brush, put a little ring (usually rings come separately and are different colors) an your new one and put it on the handle - it will hold.

SOURCE: why is my oral b braun B Professional care 500 not charging

Test the voltage of the charger base. This is a simple method to see if your brush is getting power from the base. Touch the metal connectors with the voltage tester. This should light up the tester. If not, it is losing electricity somewhere within the base.

Generator burning my electronics up


take you generator in and have the output tested for correct voltage and sine wave configuration
electronics rely on a perfect sine wave ac current as a manufactured sine wave affects electronic components such as capacitors, transistors and diodes
generator sets that run an alternator ( not an inverter ) have a pure sine wave and have less affect on electronics.
go google and type in search headings like ---sine wave, inverter sine wave, sine wave affects on electronics, alternator operation and inverter operations and then you may get a pointer as to why your inverter gen set is affecting your electronics

WHAT IS A POWER INVERTER?


A power inverter is an electronic device that converts electricityfrom one form to another. Power inverters have become more popularrecently as the technology has become more efficient and much moreaffordable.

The most popular use for a power inverter isconverting battery electricity into mains electricity. For exampleconverting your car batteries' 12 volts DC into mains electricity 240Volt AC (Australia) or 110 Volt AC (USA).

WHAT POWER INVERTERS WILL HELP YOU DO
  1. Power inverters enablemains operated electrical equipment to be used even where there is nomains outlets, like in your car, caravan or even on your boat!
  2. Powerinverters bring creature comforts from home when you go camping orcaravaning allowing you to use your TV, fridge or electric shaver infact most of the normal mains powered conveniences from the home.
  3. You can charge your laptop in the car even if it doesn't happen tohave a 12 volt adapter. In fact a power inverter can be a very handygadget just to have in your car for those times you need to use a mainspowered appliance while you're away from a power socket.

WHAT TO LOOK FOR WHEN BUYING A POWER INVERTER
Apartfrom looking for a good quality well priced product there are a coupleof important elements to consider when selecting your power inverter:

HOW MUCH POWER IS ENOUGH ?
Powerinverters come in a range of power capacities so selecting the rightone for you is very important. Your power inverter needs to be able toprovide sufficient power for the equipment you want to use it with.
Here is a brief check list:
  1. Check the power consumption for the device you want to power
  2. Allow an additional 20% free board
  3. Add the power for all the devices you want to run at the same time
Note also that devices with induction electric motors like an power saw mayrequire 3 to 7 times the operating power when they start.
Usingan under-powered power inverter may damage it or the appliance you aretrying to use, so be sure to check the specific wattage requirementsand operating instructions for appliances / tools to be used.

PURE SINE WAVE INVERTERS
Normal mains power is known as Alternating Current (AC) and is a sine wave shape like the black line in the drawing below
Pure sine wave (black) versus modified sine wave (red)
Atypical power inverter produces a 'modified sine wave output' like thered line in the drawing above. While this works for most appliances,light dimmers, variable speed drills, sewing machine speed controls,some laser printers etc. will not operate correctly with a modifiedsine wave power inverter.
Pure sine wave power inverters areespecially designed to provide a more accurate sine wave output and socan be used with these appliances, but unfortunately they are moreexpensive.
Check with your with appliance manufacturer or itsspecifications to confirm if you can use a conventional power inverteror will need a pure sine wave inverter.
WARRANTY
One of thegreat things about electronic equipment is there is no moving parts(although there is a fan in some models) so you can expect a longserviceable life from a power inverter.
STANDARDS
Powerinverters generate dangerous mains voltages so ensure the product youchoose is approved for use with your mains voltage and supplier.
Powerinverters can also generate electro-magnetic radiation that caninterfere with other electronic equipment such as radios transmittersetc. Check for compliance with relevant standards such as C-Tick etc

SAFETY
Powerinverters can generate potentially lethal voltages so the utmost ofcare should be exercised using them to avoid accidental electrocution.

SUMMARY
To select your power inverter carefully check the power requirements for the appliance(s) you intend to use it with.
  1. Start power - Allow up to seven times for an induction motor
  2. Operating power - Allow a 20% margin
  3. Pure or modified sine wave

Can I plug a camera, shaver, or cordless tool battery charger into this Modified sine wave


Yes you can and no it won't harm it unless something is wrong with it or the charger.

The inverter output doesn't get to the battery, just the chargers output.

It is becaus the inverter erradiate EMI (Eletro Mechanical Interference) and the EMI is picked up by the TV antenna, try moving them a part as far away as you can from each other (the inverter and the TV antenna), there are also some filters you can pusches, but enven with all that stuff you could end up with EMI any way so don't spend to much,

Good luck!

Hi i have a 400w black and decker inverter as soon as i plug my lap top in to it the power light on the inverter flashs and it wont power my laptop


The output of this inverter (and most others) is a modified sine wave, which isn't quite the same as a true sine wave - like you get from a wall outlet. Unfortunately, most transformers (which is essentially what your laptop power-supply is) require a true sine-wave. Your inverter will work fine for many other 110V applications. You can buy an inverter with a true sine-wave output, but they are more expensive.

T.V dosen't work with battery or inverter


The TV use 110V 60Hz sine wave AC, after rectified will be 156V DC, your inverter may be output 110V square wave AC, after rectified only 110V DC, it is too low for the TV work. except it can adjust to 155V.

Charging laptop in car


Most inverters create a modified sine wave output, which is similar to, but not the same as the AC you get out of the wall. The power supply for many laptops (and most transformers in general) will not run with a modified sine wave input. There are devices available that skip the inverter and the power supply. They go directly from 12VDC to what your laptop needs.

Had a similar problem with the same inverter BUT to include a failing cooling fan.

NOTE:
Take it back and get your money back as soon as possible.

Replaced it with a pure sine inverter 1500 watt that is kicking **** 24 seven days a week on my solar / wind power system.

RECOMENDATIONS:

UPGRADE.

Run a CPAP on a power inverter


I would not do this, you really need a pure sine wave inverter to guarantee the safety of your CPAP machine. At the price they are selling this device it could not be pure sine wave. 150W pure sine wave would be $70-$100.
