No, not possible. The charger has to go to higher volts than the battery being charged.

What is 12v 18ah battery?
12v means it is suitable for any 12v dc current purpose the 18ah means it has an amp hour rating of 18 its a measure of how long the battery can work from full charge until it would need to be charged again ex. the bigger the ah rating the longer you could turn the starter for before the battery would run flat
Can the 2.2 microfared 250V capacitor be charged with 12V dc source?
Yes. The 250 voltage is a not-to-exceed rating.
Can you use a DC 9v 300MA adaptor to power a 9v 400MA device?
The voltage would match but the amount of power would likely not be enough to run the device. Under-power will not likely harm the device, but it won't work correctly. Always use the correct voltage/power for your devices!
How many volts does a computer monitor use?
from the wall it could be 115v ac, or in non American countries that use it 230v ac. internal voltages range from 12v dc, 5v dc, 3.3v dc.
DC VS AC?
DC is constant in directionAC is reversing in direction
Can i use 9v dc with 12v dc?
No. 9 v is only 75% of 12 v.
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
What the conclusion that can take in multiple dc power supply?
conclusion of dc power supply 9V
Can a 9v dc motor produce 9v when it is used as an alternator?
A: No problem but don't expect the power to increase
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
Can you use a 9v dc 1000ma adaptor for a device that has 'power input' of 15v dc 800ma?
A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
How does 12v dc 1.5 amp power adapter differ from 12v dc 3 amp power adapter?
12v 1.5amp power adapter is 18 Watt, can't load more than 18W power consumption,3amp power adapter can load 36W.
Can you use a 12V DC adapter for 5V DC device?
input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.
Can 10kv dc power be stepped down to 12v dc power?
Not without a lot of very expensive equipment
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
What will happen if lead acid battery is charged with ac power?
It will more than likely explode. You charge the battery with a charger that coverts 120V AC to 12V DC.
How do you charge a supercapacitor?
use a dc power source. preferably an ac/dc power adapter. any dc power source will do.
