# Can I use a 5V adapter for 6V device?

## Can I use a 5V adapter for 6V 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.

### Can I use 500mA instead of 250ma?

As long as the voltage output is correct for your unit it is okay.

#### Will too little amperage hurt a device?

The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used. The device being charged may be damaged.

Can I use 7.5 V adapter for 6V?

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

Can you use a 12V adapter for a 6V device?

It does have a maximum resistance that it will will reach, and a breakdown voltage. In your case, the zener voltage in your hardware is probably 6v and it’s max impedance is 6 Ohms or more. As long as your device does not exceed the zener’s maximum power handling, you should have no problems.

## Can I use a 6V adapter for 4.5 V?

Registered. If the radio uses a linear voltage regulator then you can use voltages as high as the maximum of the voltage regulator, as long as it has enough heatsinking.

### Can I use 1000ma instead of 300mA?

Re: OK to use a 300ma adaptor with 1000ma Roland device? No. Maths in these matters is simple: to power a 1000 and a 300 mA device, you’ll need (at least) 1300 mA and probably some additional circuitry to prevent the smaller device from slowly frying.

#### Can I use an 18V power supply for a 9V pedal?

Generally you can safely plug an 18v pedal with 9 or 12 V but there is a good chance that it will work poorly… (although it might give an interesting distortion effect). If an 18V ped has digital save data, better not chance it. You may corrupt your sweet patch or loop.

Can I use a transformer with higher amps?

Yes, you can. The Volt ratings must match, but a higher Amp rating is OK. This only indicates how much current the power supply is capable of delivering if the load demands it, not how much it will deliver.

What happens if amperage is low?

We recommend higher amperage to ensure cooler power supply and optimal charge time. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.

## Can I use a 12V power supply on a 6V?

For a battery charger to work properly, the charger voltage must be the same as the battery voltage. With a few modifications, a lower voltage (such as a 6V) battery can be charged with a larger (such as 12V) power source.

### Can I use 1000ma instead of 500ma?

If the device requests 500ma and the power supply can handle up to 1000ma, it’s fine. The device will only draw what it needs and no more. If the device requests 500ma and the power supply can handle up to 1000ma, it’s fine. The device will only draw what it needs and no more.
