Can You Use A Power Supply With Less Amps at Hilda Connor blog

Can You Use A Power Supply With Less Amps. 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. Any device will only draw as much current as it needs, so long as its power source can supply it. One solution that might work for you if you're willing to do a little electronics work is a 9vac adapter (which are cheap and common as dirt), plus a power resistor to drop. The power supply will normally supply the rated voltage up to the rated current. I have an old router with a 12v 1.5a rating, and its power supply died so i'm using a 12v 1.2a power supply. No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device. You can use a power supply with a higher rating on current (amps) or total power (current * voltage, so directly related anyway). I have a midi keyboard with a 9v. Just because a 12v power supply can supply 10 amps, doesn't mean that the power supply. However, the laptop adapter's voltage is a full volt above the specified 18 v; If the power supply voltage is significantly more,.
