Can I use a 9v adapter for 6v?

You can run a 6V motor at 9V — it will run faster but won’t last as long. … If you can be sure that the original PSU was unregulated, then yes a 6V or 9V adaptor will work (as long as the polarity is right and the PSU is powerful enough – mA high enough).

Can you use a 9V adapter for 5V?

The problem with supplying this with 9V is that the current through the circuit would be theoretically near infinate and, as FullFrontalNoodly said, in real life will destroy the circuit very fast. This is because voltage is pressure, like triffid said. A 5V circuit, like a couple LEDs, would leave 4V.

Can you use 9V adapter for 7.5 V?

The long term effect of using 9 V instead of 7.5 V is unpredictable. It depends on the construction of the baby monitor’s electronics. It may work or fail… Chances are that the 9 V adapter outputs a bit less than 9 V.

Can I use a 12V adapter for 6V?

– 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 a 6V adapter to power a 5V device?

You could convert the 6V adapter to 5V if you’re comfortable with electronic circuits. This can be accomplished by hooking up the output of the adapter to a simple 5V linear regulator, which will probably have a dropout of 200mA.

Is an AC adapter a Charger?

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.

Can I use a 4.5 V adapter to power a 5V device?

They’re very stable on the output voltage and can kick out an amp or so. It’ll work fine.

Can I use 12V Adaptor 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 I use a 5V adapter to power a 3V device?

There is not such thing (or there should be no such thing) as a 3V USB anything… USB is 5V, and always will be. It is a standard that all devices must comply with. This means that you should not be able to find an AC adaptor to 3V with USB, If you do find it, don’t buy it.

Is it OK to use higher amp adapter?

The amperage rating on your power supply simply means that the supply can put out up to 2 amps, so as long as the voltage matches (12 volts) you could safely use a higher amp power supply for your device.

Can I use a 19v charger for a 20v laptop?

20v can be used for 19v provided that the current score of 20v is equal or higher, but only temporarily. The best to charge the battery and then disconnect and run the laptop, notebook etc on your own batteries to ensure a correct entry into the circuit. Runng 20v for 19v directly is not recommended.

Can I charge a 19v laptop with a 12V charger?

NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply. You need a battery charger. The laptop power supply IS NOT a battery charger, it is a fixed voltage SMPS power supply.

How do you convert 12V to 6v?

It’s possible to step 12 volts down to 6 volts by incorporating a pair of 10,000-ohm resistors into the circuit. Cut two lengths of wire, and strip each wire of 1/2 inch of insulation at each end. Attach one end of the first wire to the positive terminal on the power supply.

Can I use a 4.5 V instead of 6V?

An incandescent filament lamp designed for 4.5 V would burn brighter and hotter at 6 V applied voltage. While it may work, reduced life or outright falure is possible. A simple “buck” voltage regulator would allow the 4.5v device to operate from a 6v or higher voltage battery without risking damage.

Can I use 7.5 V adapter for 6V?

No. The supply would not be able to provide enough current and would likely overheat.
