Can I use a charger with more output amperage than the device needs?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
Can I use 600mA instead of 500mA?
You’re going to feed it 4.5V with both devices, the difference between the 500mA and the 600mA is just the maximum amount of current the devices can deliver. So basically, a 600mA will be at least as good as a 500mA, since the new Volts require less current. Aelus is 100% right.
Can a power adaptor with a lower current rating be used?
A n adaptor with a lower current rating than required may not be able to supply sufficient power for the pedal to operate as intended. But, as we now know, a pedal will only draw as much current as it needs, so any adaptor with a higher current rating than recommended is perfectly safe.
Is it better to use a higher power adapter?
Usually, a higher power adapter will be more expensive, so if you have the option just match the device’s power. Your device is unlikely to operate if you have an adapter with a lower A or mAh output then the device, and if it does operate the adapter is likely to get very hot and could be dangerous.
Which is the correct voltage for an AC adapter?
It is important to use the correct volts when choosing the adapter as a device can only run on the rated voltage. The most common are 18V, 12V, 9V, 6V, 5V and 3V. Once you have confirmed the voltage of the device we need to find the amount of current that it uses.
How can I tell what kind of AC adapter I Need?
Amps: This is also usually written on the devices sticker or near the power port, this is measured in A or mAh. The adapter you choose must be able to supply at least the current rating of the device. Do not worry if the adapter has a higher rating as the device will only consume what it needs.
