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.
What is a DC 9V adapter?
The adaptor converts AC wall power to 9-volt DC for powering most instrument pedals and other 9-volt battery devices. The tip negative, sleeve positive power supply can handle 500mA to power even your most power hungry devices.
Are all DC 9V Chargers the same?
Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.
Can I use any 9V DC adapter?
Any adapter over 10-15mA at 9VDC (center negative only!) will work. You don't have to buy a Boss labeled adapter. Not all power supplies are equal. Some are made with lower noise tolerance for audio applications.
Can I use any 9V adapter?
You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original. If you use one with significantly more voltage (and 12v is a full third more than 9v) then you might burn out your device.
How do I know what size DC plug I need?
If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD). ID an OD measurements for both the female and male connector must match to connect properly.
Can I use higher voltage DC adapter?
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.
How do I know if my charger is compatible?
- Simple. Check the rating on it.
- Standard smartphones use 5 V chargers at about 1.5 A output. Laptops use a 19 V charger at 3.9 to 4 A output.
- If the charger you have with you has a compatible connector type with your device and matches the standard rating, you're good to go!
What is a DC adapter used for?
Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop.
What uses a 9V power supply?
A lot of things use those small 9V batteries. Smoke detectors, some transistor radios (not so much any more), lots of handheld test equipment, electronic toys, etc. More and more things that in the past typically used 9V batteries are being designed to run from one to four AA or AAA cells.
What does DC 9 12V mean?
According to your question, It means that the charger can provide either a output of 5 volts or between 9 to 12 volts with its output current ranging from 2 ampere to 2.7 ampere.
Can I use 12V charger for 9V battery?
Similarly, you can charge a 9V battery with a 12V charger, and we show it in more detail below with Lithium-ion and NiMH batteries . The 9V li-ion battery is made of two 3.6V cells lending it a nominal voltage of 8.4. To safely recharge it you need a voltage source of 8.4V.Jun 3, 2021
Can you charge a 9.6 volt battery with a 12 volt charger?
The answer is no, not directly. If the 12V battery is completely discharged, a 9.6 V battery connected in parallel to it, will put some charge into the 12V battery but no where near enough for the 12V battery to be fully charged.
