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

Product Information

As long as the correct voltage is used, a device will draw only the amperage it needs, meaning there will not be “too many amps”. If an incorrect voltage is used — say a higher voltage than the device is rated to accept — then yes, too many amps may be drawn, and the device can be damaged. This is why it’s critical to use the correct voltage. Can I use an AC adapter with higher amps?

Company policy is that we do not under any circumstances issue instructions to our couriers to leave deliveries unattended when no one is at the delivery location. Yes. 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. Is 500ma the same as 0.5 A?

Do this

It is my understanding that the volts you are trying to input should be the same or less than the device you are charging. While the amps should be the same or they can be slightly higher than the device you are charging.

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. 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. Does more volts mean more amps?

The problem, of course, is the reverse: if your device needs 1.0 amps, but your charger is rated at only 0.5 amps, then any of several problems could result: If you look closely at the small print on many power supplies, you’ll see they’re rated for anything from 100 to 250 volts. This means most can work worldwide with nothing more than an adapter to account for the physical plug differences — no voltage transformer needed.

Of course I was excited to do it. My thought was that if the Nintendo car adapter charger steps 12 volts down to 4.6 Volts at 900 mA, then this new cable should step 5 volts down to 4.6 at 900 mA. But it did not work.The amperage provided by your charger must match or exceed what the device being charged requires. Amperage Provided Versus Amperage Required Power Supply or Charger Amperage Rating Power supply efficiency is known as the amount of power actually provided to the internal circuitry, divided by the amount of power drawn from the mains supply. If a PSU is 50% efficient and is required to provide 50 Watts of power, 100 Watts will be drawn from the main supply. The extra 50 W is lost as heat. A 90% efficient PSU would draw 56 W in the same circumstances. What industries can power supplies be used in? Unfortunately the gauge of the USB 2.0 cable is really a high number (meaning that the wires are few and small). I’m thinking I should redo my cable and use a USB 3.0 cable because I think it may be able to handle the Voltage.

If I knew what kind of resistor I can buy to solder in with a wire that would be about my only option.It’s very important to get the right voltage. Some devices are tolerant of variations and work just fine. Others, unfortunately, are not tolerant at all. 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. Electrically speaking, higher voltage can cause more amps to “flow”. 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. Can too many amps damage a device?
