Sure. You actually need a little more than the rated battery voltage to charge a battery. Half a volt out of 9 is only about 5% which should be about right. Just check the charge current to make sure it is not more than recommended by the manufacturer, or absent a recommendation, it should not make the battery hot.
Can I use 9V adapter for 8.5 V?
Most likely no. For a start, mobiles require relatively low current, thus applying that to a 9v battery will reduce it further. Also unless you use additional circuitry to increase the voltage, you will NOT reach 9v, and hence you’ll struggle to even get ANY voltage.
Can I use a 9.6V power supply for a 9V pedal?
You will be fine. A fresh 9volt battery actually puts out 9.6 volts .
What happens if I use a 9V adapter on a 12V device?
Plugging in an adapter with a lower voltage would not generally harm the unit. But if the polarity is reversed then it probably would cause damage and that may be what has happened. It may just have blown a fuse.
Can I use 9V adapter instead of 9V battery?
Batteries are a completely isolated power source. Now, if you have a regulated 9 VDC adapter which is rated to provide more current than your device ever requires, it will likely work as a substitute for the batteries.
Can you use 9V adapter 6V?
No. The power supply is capable of producing one ampere, if the device draws that much, but it won’t force that much current through the device. As long as the voltages are matched, there’s no harm in using a power supply with a higher capacity (better higher than lower).
Can I use 9V adapter for 8.4 V?
It’s not recommended, but might be ok. 7.4V Lithium batteries actually span a 6V to 8.4v voltage range depending on state of charge of the battery. So you’re putting 9V into a device that is definitely designed for wide-input voltage, up to 8.4V.
Can I use 9V adapter for 12V?
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.
Will 9V power supply work on 12V device?
No. The power supply is capable of producing one ampere, if the device draws that much, but it won’t force that much current through the device. As long as the voltages are matched, there’s no harm in using a power supply with a higher capacity (better higher than lower).
Can I use a 9V instead of a 12V?
It depends on whether your power supply is regulated. If you need regulated (stable) 12V, and the 9V supply is unregulated, it could give you up to 14V or slightly higher when not loaded.
What uses a 9V charger?
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 devices use 9V?
A nine-volt battery, either disposable or rechargeable, is usually used in smoke alarms, smoke detectors, walkie-talkies, transistor radios, test and instrumentation devices, medical batteries, LCD displays, and other small portable appliances.
Can I use 9V instead of D batteries?
Never, never, never mix capacities of batteries in series connections. It will not behave as you might expect and can cause serious problems. Mixing an alkaline 9V battery with a couple of D cells could cause the 9V battery cells (internal) to heat and spew out caustic liquid.
Will 9V work 5V?
No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn.
Can you run a 6V motor on 9V?
A 6V motor can run with a 9V battery but the motor will probably heat up. So to step down the voltage you can use linear voltage regulator (LM7806), or buck converter.
Can I use 9V for 5V?
Of course it’s not alright to use a 9V adapter for a 5V device. Why would we provide the voltages ratings if it didn’t matter? Only if the 9 volts is regulated by a 5 volt regulator like the 7805. This is a very common situation.
Can I use a 9V power supply on a 8v?
If the old supply put out 8 V and 2.6 A and the equipment says it wants 8 V, then the obvious answer is a power supply that puts out 8 V and 2.6 or more amps. The equipment might be OK with 9 V, or not.
Can I use a higher amp power supply?
Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous, you’ll be fine.
How much voltage does a PS4 need?
The PS4 is powered via an internal wide voltage range (110–240 V AC 50 Hz/60 Hz) switched-mode power supply.
Will a 9V charger charge a 12V battery?
You cannot use a 9 volt charger as it will not be capable of providing enough voltage. A 12 volt battery (I’m using a lead-acid battery as an example) needs a charging voltage of about 13.5 volts to properly charge the battery. The standard charge level typically used in automobiles is 13.7 volts.
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.
