Need a charger for a Kawasaki power wheels 4 wheeler model: new ninja. What kind do i need for a charger 12 volt for this?


I suggest you refer to the instructions for the specification.

The first requirement is fitting the charger socket and the next is having the correct polarity.

The type of battery is important and the required charge rate/time is also important. A lead/acid battery should ideally use a constant voltage charger. Ni-cads and similar should ideally use a constant current charger.

The vehicle might have it's own intelligent charging circuitry and just need a power supply but if this is not so then the more sophisticated the charger you buy, the longer life the batteries will have.

What is the power voltage for the x235 got display model dosent have a power lead


There should be information about that cast into the outside of the display housing, Charlie, or it may be printed in insanely small print on the serial number label. Most likely, though, it'll be cast into the housing near the power jack. It'll also indicate polarity, but it won't tell you which size the power plug needs to be.

If you can't find the voltage & current requirements anywhere but you CAN find the little polarity indicator, you could buy a "universal" power supply with switchable voltage and polarity. Start with the power supply set to the correct polarity and the LOWEST voltage. If it doesn't work, step up one notch and try again. Increase voltage ONLY until the unit functions, and NO higher. Tape over the voltage selector switch when you have it right.

So i lose my Literati charger right after my birthday! I cant find it anywhere and i found my old t mobile charger and it fits perfectly. But i cant tell if its chargeing and it wont turn on! Please help...


Stop!

There are no voltage and amperage "standards" for low voltage connectors found on devices made to run from an external "wall wart" or transformer type charger or adapter. Just because a connector "fits" does not mean the power is 1) the correct voltage 2) correct polarity 3) correct type (AC or DC) or 4) can supply the amount of power needed to operate the device.

You may have done irreversible damage to your device by literally "grabbing any old charger that fits" to power it. Obtain the correct charger - or if unable to find one; determine the characteristics needed by the device - those variables are listed in 1 through 4 above.

You may find adjustable power sources that allow 1) changing of tips to fit the device, 2) a selector to choose from a range of voltages, 3) a switch to select AC or DC output and 4) the ability to plug in the tip backwards so that the polarity reverses. The last thing needed, is to know how much current in amps or power in watts is needed by the device. The charger / adapter should be chosen on its ability to supply this power continuously - never choose a charger / adapter that provides less than any of the electrical requirements; otherwise damage to the charger or device may occur - and if left unattended, could overheat and cause a fire.

I hope this helps and good luck! Please rate my reply. Thank you.

Possibly you just need a new power supply/battery charger. There is nothing "magic" about the original power supply. Take the player into an electronics supply shop. They should be able to look at it and match

Ineed the voltage and connector polarity for the ADS TV ELite Pro


I just found one too, same situation... no power supply. Mine has box and all. On the back of the box, it reads:
Power Supply 7.5 VDC power adapter

It doesn't say what polarity, but judging from the board... I'm gonna' say + in the center. That's what I'm gonna do.

BEFSR41 power supply?


Both the voltage and the polarity should be printed on the case of the router. The polarity should be right next to where the power plugs in.

The polarity information will look something like this:
--(-(+))--

If you take the router into a local Radio Shack, the clerk will probably be able to tell you which power supply you need.

Charger


next to the jack on the camcorder it should have a diagram that shows polarity (a + and - sign) for the plug, the tip should be one sign and barrel or outside of the plug should show the other polarity. you have to have your plug with the correct polarity, and you have to have the correct voltage( it should say 9v or 12v or something like that) and the supply you use should be as high or higher of a current rateing as recommended in your users manual or printed on the supple that came with it.

What is the voltage, current, and polarity of the power supply for the SC-D23?


You should use the original Samsung supply since it is a switching power supply capable of supplying the needed current to operate the onboard charging circuit. Many customers have tried to go with generic supplies and it opens the inline chemical fuse due to the unit drawing heavy current during battery charging. Hope this helps.
