If the charger cannot supply enough of the current that the device wants, if may decide that it doesn’t have enough to run. 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. Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous, you’ll be fine.

Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Your water analogy is incomplete: voltage is the water pressure, and amperage is the SIZE of the hose.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. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. An example being a water pipe with a pressure/voltage of 10psi and a diameter(volumn)/current of 1 inch allows so much water through. The losses increase a the square of the current so a doubling in load will more than quadruple the I We have a wide selection of power supply units (PSUs) for use in various domestic and industrial applications.

Can I Use a Charger With the Same Voltage but Different

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. Thinking of purchasing a 12 V ac adapter, well look no further, here at RS we offer a range of high-quality power supplies to suit your every need. If a PSU is 50% efficient and is required to provide 50 Watts of power, 100 Watts will be drawn from the main supply.If the device expects the center connector to be positive and the outer ring to be negative, your power supply’s connector must match. 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.

The input line voltage (wall or “mains” power) must be supported but is unrelated to compatibility with the device being charged or 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. 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”.in 2003 as a place to help you find answers and become more confident using all this amazing technology at our fingertips.
