AC to DC 12V 1.5A Power Adapter Supply, Plug UK 5.5mm x 2.1mm

Product Information

As long as the voltage matches that expected by the connected device, then yes, you can use an AC adapter capable of providing higher amps.

Can I Use a Charger With the Same Voltage but Different

AC chargers are usually represented by a tilde (~), and pulsating DC chargers are indicated by a solid line over a dotted line, kind of like highway dividers where there’s no passing in one direction. 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 being powered or charged. Plug a device expecting 110 volts into a 220-volt socket, and you’ll probably see sparks followed by darkness as the circuit breaker trips. I'm Leo Notenboom and I've been playing with computers since I took a required programming class in 1976.The output amperage must match or be greater than that required by the device being charged or powered. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. If the device expects the center connector to be positive and the outer ring to be negative, your power supply’s connector must match.

The losses increase a the square of the current so a doubling in load will more than quadruple the I But in terms of making the concepts usefully understandable to people who don’t care about Ohm’s law I think it works. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to. Depending on how different the supplied voltage is from what’s required, the device may simply fail, it may work “kind of”, or it may appear to work at the cost of a much shorter lifespan. Andrew’s comments are more about the internals of a device being run but the question was about the current rating of a charger.

By the way, does the voltage and amperage output for each USB port decrease when you are using more than one USB ports at the same time? Because a) the voltage matches, and b) the amperage provided is greater than that needed, you can use a 5v-2A charger with a 5V-1A device.

This is one reason why getting the voltage correct on a power supply is so critical, because it can, in a sense, “push” too much electricity through a device and cause it to overheat or be damaged.The PSU also converts the current rating, in the form of AMPS, to a level that is safe for the device that is to be powered. The input voltage and amperage ratings are unrelated to the charger’s compatibility with your device.
