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

Product Information

A small hose under a lot of pressure will get you wet; a huge hose, even under low pressure, can wash you away. If you load up a power supply, you will have losses in the wire that connects the supply (wall wart) to the device. This means most can work worldwide with nothing more than an adapter to account for the physical plug differences — no voltage transformer needed. The input line voltage (wall or “mains” power) must be supported but is unrelated to compatibility with the device being charged or powered.

Here’s the catch: just because the physical plug fits into your device does not mean that the polarity is correct. I know that with my Dell laptops, if the chip in the charger goes bad (the chip that tells the Dell laptop that this charger is the correct charger for the computer), it will no longer charge the battery, and the laptop will draw less power (or amps – but Amps times Volts gives you Watts – or power) – thus slower laptop. If the device expects the center connector to be positive and the outer ring to be negative, your power supply’s connector must match. I could agree with your definition of Voltage – the ‘push’ on the electrons that tries to make them move and make a current, but not your definition of Current. 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.But I thoroughly agree with your working rules; get the voltage exactly right, and only substitute a higher current power pack where a lower current one used to be.

Power supplies are a crucial aspect of any electrical equipment, providing reliable power to machinery, computers or other technology devices.

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”. The losses increase a the square of the current so a doubling in load will more than quadruple the Iamps maxium per connection (that’s often why you’ll find some devices that connect to two USB ports, because they need more than 0. I’m looking to purchase a USB recharger that plugs into the wall for use with a MP3 player when traveling without a PC. in 2003 as a place to help you find answers and become more confident using all this amazing technology at our fingertips.

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.Remember what the article said: the voltage remains constant, and the amperage is dependent on the device’s needs, regardless how many are connected. Our range includes AC-DC power supply adapters and desktop computer power supply suitable for domestic applications, as well as bench power supplies, DIN Rail and panel mount power supplies and switch mode PSU.
