Pay Attention to the Orange Parts

In the orange parts, labeled 4 and 5, you will find useful information for your selection.

"V" - Voltage in Volts at which the device operates
"A" - Current in Amperes consumed
Power "W" in Watts is calculated by Voltage times Amperage (V x A)


Example

Input: 100-240V
Output: 19V DC and 4.74A

Therefore, to replace this power supply with a similar device, you need to look for a power supply with a Voltage of 19V (+/- 0.5 Volts), and the current should be at least 4.74A. If it is higher, there won't be any issues.
