No, not possible. The charger has to go to higher volts than the battery being charged.
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
Yes. The 250 voltage is a not-to-exceed rating.
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!
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.
A DC jack exists for the purpose of supplying direct current to a device from an external source, as opposed to the batteries inside the device. The external DC power would likely come from an AC to DC adapter that you plug into the wall. Such a jack can also work with car adapters too, provided it it converted to the correct voltage. So using an external source keeps you from using the batteries. With some equipment, that can charge the battery as well, but devices using disposable batteries are wired as to not charge the batteries.
No. 9 v is only 75% of 12 v.
DC 12V power supply can convert 110/220V AC power source to 12V DC.
conclusion of dc power supply 9V
A: No problem but don't expect the power to increase
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.
Not without a lot of very expensive equipment
input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.
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
The main difference is the amount of current each power adapter can supply. The 12V DC 3A power adapter can provide up to 3 amps of current, which means it can power devices that require more current compared to the 12V DC 1.5A adapter. This can affect the compatibility and performance of devices connected to the adapters.
No, it is not recommended to plug a 9V DC power source directly into a 220V outlet. Doing so can damage the device connected to the 9V source and pose a safety hazard. It is important to match the voltage requirements of the device with the power source to avoid potential damage or injury.
It will more than likely explode. You charge the battery with a charger that coverts 120V AC to 12V DC.
if you have 12v dc then you can use a 4 ohm resistor
