Does 12V work on 15V? Distinguished. Assuming the polarity is correct,
plugging in a 12V input to a device requiring 15V won’t do any damage
, however if you undervolt an amplifier, you may get clipping or other distortion.
Can I use 15V charger for 12V?
It is quite inexpensive but
voltage goes right up to 15V
which is higher than what what 12V 7 AH wants (about 14.2V). secondly, it delivers max about 1 amp when battery is about 9V. It does not output 2 amps. When charging battery around 12V, it takes a very long time – about 4-5 hours to go up to 13-14 V.
Can I use a 12V power supply on a 19V?
No, don’t use it
! The PSU will supply 19V (“voltage source”) and will probably damage the load. There are PSUs that limit output current by dropping/regulating the output voltage (which then can be considered a “current source”), but as long as the required current isn’t constant that wouldn’t work either.
Will 12V work on 14V?
Can I use a 12V power supply on a 18V?
IT DEPENDS
. There are many circuits/devices that are extremely flexible in terms of their power needs/requirements/tolerances. In some instances, pedals/devices can sometimes “work better” with a higher supply voltage. A great many circuits in the guitar world, however, presume a 9v or 12v supply.
Can you use a 12V charger on a 16v battery?
Your 12v adapter would only be able to raise the battery voltage to 12v, but to charge a car battery fully you would need to raise the voltage to 13.8v.
The 16v adapter would raise the voltage too high and could cause damage
.
Can I use 19V charger for 12V battery?
NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply
.
Can I use 12V for 19v monitor?
Yes, as long as it supplies the 1.5Amps at the 19Volts plus a bit more (surge) current (Amps) for any startup, charging caps and all, and it will work fine
.
What happens if I use the wrong voltage adapter?
The device could power on and draw more current from the adapter than it’s designed for
. This could cause the adapter to overheat or fail. Or, the device may power on, but the adapter may not be able to keep up, causing the voltage to drop (see voltage too low above).
Is it OK to use a higher voltage power supply?
Higher current (A) is okay because the device won’t use as much, but
higher voltage (V) is going to “fry” it
. Conversely, lower voltage is unlikely to cause damage since the device simply won’t have enough power, but lower current can cause trouble because the power supply cannot provide enough.
Can I use a 15v power supply on a 9V?
If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases,
you cannot use a 12V adapter to power a 9V guitar pedal
. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.
Can I use 18V charger for 12V battery?
Definitely DO NOT attempt to charge your 12 volt battery with that power supply
– it will do its best to get the battery voltage up to 24 volts (or whatever voltage it is set to). The battery will probably be destroyed (perhaps violently) by the resulting high current.
Will a 12 volt charger charge a 14 volt battery?
14.4v is the charging voltage required to charge the 12v battery
. That’s where I got confused. Any battery charger designed for a 12v battery will actually use more voltage to than 12v to achieve a full charge.
Is 16V better than 12V?
16 volt is also 20% more efficient than 12 volt
, meaning you will get longer run times on the equivalent amp hour rated 12 volt. Example, 16V 80AH will get similar run time to a 12V 100AH.
Is 15 volts too high?
Higher than 15 volts indicates a fault in the charging system’s voltage regulator or related circuits
. If it’s substantially excessive, this can cause electrical system and/or battery damage. You mentioned your voltmeter runs at about 15 volts most of the time.
Can I use a 16V battery in my car?
According to Turbo Start,
components designated as 12V/16V should have no issues with 16 volts
. However, you should always try to check with the manufacturer for 16-volt compatibility as well as the need for a resistor.
What happens if you charge a 12 volt battery with a 24 volt charger?
If you just plug a 12 volt a battery into a 24 volt charger
it will die in a matter of hours
.
How do you convert 19V to 12V?
Can you charge a 12V battery with 20v?
Can 12v run TV?
Powering your home TV from the 12-volt lighter socket in your car, truck or RV is possible
. Since the home TV uses AC (alternating current) power and the vehicle produces DC (direct current) power which is stored in the battery, a power inverter is required to produce the type of power used by your television.
Can I use 19V charger for 18V?
Yes should be ok just,as you should try and keep to less than 5% difference if possible
. Make sure the power output is equal to or greater than the 18V one.
Can I use a 19.5 V charger on a 19V monitor?
The 19.5V vs 19V will not matter (it is a small enough difference);
as long as the current rating on the charger is at least as much as the current rating printed on the laptop it will be fine
. The chargers are “generic”; the same model is used for various laptops even with the OEM chargers.
Can I use 12V AC to power 12V DC?
Can I use a 24V power supply on a 12V?
You’ll need to purchase a transformer or voltage booster, or, more straightforwardly, a 24V power supply. The reason is that a 24V LED strip has 6 LEDs in series per group, and
there is no way to “split” this to match a 12V power source
.
Can I use a 10v adapter for 12V?
NO! Your output voltage is wrong
, which is the important part. You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original.
Can I use a 24V power supply on a 9V?
The negative effect will (probably) be damage to one of the circuits inside. 24V is nearly 3 times 9V so
it is not a good idea
.
Can I use a 12V 3A power adapter on 12V 1.5 a device?
Yes, you can use a 12V 3A power adapter on 12V 1.5A device
. You can also use a 12V 0.5A power adapter but the charging time will be three times longer.
Can I use 12V 1.5 a for 12V 2A?
The answer is
no then yes
. Obviously, you can’t power a device that requires 1.5A if the supply will only provide 1.0A. The 2A supply will work just fine.
What happens if I use a 12V adapter on a 9V router?
Can I use a 12V power supply on a 9V fan?
Can I use 12V charger for 9V?
You can’t use a 12V adapter to power a 9V guitar pedal
. A pedal that only handles 9V can be destroyed by using a 12V adapter. It’s possible for a power supply to ruin your pedal even if you get the voltage right.
Can you charge a 12V Makita battery on a 18V charger?
Can you charge a 14.4 v battery with a 18V charger?
18V is around the right voltage to charge 14.4V batteries from
. However, you’re probably seeing a charger intended for 18V batteries, which will actually be giving closer to 22-24V, too much for 14.4V batteries.
Can I connect 18V solar panel to 12V battery?
Should I set-up additional buffers closer to matched voltage and then step-down to 12V? The thing is, matched voltage/load for such panels is 18V not 12V.
You cannot directly attach solar panel to the battery anyway, regardless of the voltage
.
Can you charge a 14.4 V battery with a 12 volt charger?
14.4v NiCAD should only be charged with a charger designed for NiCAD, at 14.4 volts
. Unless you have some REALLY old laptop chargers, they will be Lithium Ion. Regardless, using the wrong voltage isn’t ideal. Battery chemistry is important and you risk a fire by using anything other than what is intended for the job.
What is the maximum voltage to charge a 12V battery?
The peak charging voltage for Gel batteries is 2.3 to 2.36 volts per cell, and for a 12 volt charger this works out to
13.8 to 14.2 volts
, which is lower than a wet or AGM type battery needs for a full charge.
