SOURCE: what is the polarity of a 12v Black & Decker Drill?

centre pin on plug socket is usually positive...
think I would **** it and see ....if the replacement charger has a charge light it will probably not light if you have reversed polarity. Had the same problem with VHF portables ...I just cut the wire on new charger and tried both options ..reconnected and a bit of tape...voila.
There is little danger to your drill from getting it wrong as long as a the timing is relatively short.

I need to find a ac/dc charger for a Defiant Flashlight Model 800-2701D Can you help??

This flashlight is sold by Home Depot, and it is possible that you might be able to find a name-brand exact replacement charger there. However, you almost certainly can find a replacement charger elsewhere for less money.

Looking at a picture of the light and its power adapter, it appears that the light has a standard barrel charging port. A dollar store or "Dollar Plus" store is likely to sell inexpensive multi-voltage universal chargers that will fit this light and get you back in business for under $5.

When fitting a non-OEM charger to your light, make sure that you've set proper polarity and input voltage for your device, or else you may damage it in charging. Many devices specify voltage and polarity right on the device, molded into the case or on a small sticker. That makes this process super-easy. Otherwise, you may have to head down to a Home Depot and peek at one of these lights in its box to read the voltage output off the stock charger. The odds are pretty good that it'll be putting out 12 volts, but I won't guarantee that by any means--input may be 6v or even 4.5 volts, though those are much less common in lights of this type.

Good luck!

I need to buy battery for KC 9072

Either you can buy the original battery from Black and Decker or you can replace with the same mA rating with the regular types available in all stores any rechargebale variety with a good mA rating.
Couple in series and parallel to get the desired voltage and current rating.

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...


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.

My name is Satheesbabu. I have a Canon Video camera MV 800i,purchased 6 years back. I lost the power chord. It is written on the camera 7.4V in one place and 8.4V at the power connection point. Please...

there are several power cords on ebay for your camera as well as new batteries if you need one. Do an ebay search for MV 800 charger, here is an example of one I found.

Looking for battery charger

Hi Vic,

When looking to replace a battery charger for a device there are four things that need to be satisfied.

  1. Minimum voltage (usually 10-15% higher than the battery)
  2. Minimum Amps (usually marked on the device in milliamps (mA)
  3. The plug has to fit
  4. The plug needs the correct polarity (is the center positive or negative)
Of all of these, the most difficult can be finding a plug that fits. There are 'universal transformers' out there with interchangeable plugs, variable power settings and reversible polarity.

A Radio Shack type electronics store is a sure thing. Priced at $10-15.00.

But on your way, if you pass a GoodWill type second hand store, they usually have plenty of transformers2_bing.gif of this type priced at about $2.00.

Best regards

I have a Kingavon 1 million cp spotlight (model SL1000EB ) I also have a lot of unidentified chargers. Does anyone know what charger fits the spotlight?

I will assume that your light has rechargable NiCad batteries. Use the following advice ONLY if you are sure this is true. If the light is more than a couple of years old, this is probably true. Of the plug has to fit, but it must also have the correct Polarity, Voltage, and Amperage. The spotlight should be labeled where you plug the charger into it with these three critical parameters. They will also be indicated on the chargers. POLARITY --- If it takes a round plug, the polarity is indicated by a symbol that looks like a C, usually with a plus sign inside of it (this indicates that the center contact is positive). VOLTAGE --- this will be expressed as VDC input on the light, and VDC output on the charger. The voltages only need to match within about 10%. AMPERAGE ---- this will be expressed as mA (milliamps, which is thousandths of amps) or as A (which is Amps). 1000 mA = 1 A. This doesn't need to match precisely either. But if it's too low, the charge will take a while and you might burn up the charger (possibly literally burning it). If the amperage on the charger is high, that's OK, so long as the voltage is not high as well.
I hope this helps, Thanks for using FixYa. Al Kupchella

Battery for pyramid 105 amp

There are many many possible batteries you can use for this application, from lead acid to Lithium polymer. You will need to determine what type of power connector that will fit your unit's jack then make sure the polarity is correct. You can then wire connector
accordingly to battery you select. Make sure battery exceeds current requirements but voltage. If unit has internal charger, make sure the battery you choose is compatible or use dedicated charger
