Powering the Jetson Xavier NX board from an alternative power supply

Hello.
How compatible is the Asus PA-1650-66 power supply for the Jetson Xavier NX, replacing the stock Liteon PA-1450-26 power supply that came with the Jetson?
It so happened that the stock power supply for the Jetson Xavier NX died when I tried to charge a Lenovo IdeaPad S110 netbook (I couldn’t find the stock power supply for the netbook right away, so I decided to use the Jetson’s power supply instead). When I connected the Jetson’s power supply to the netbook, a spark appeared in the netbook’s power connector, and the Jetson’s power supply died.

If I remember correctly (if my memory serves me correctly), somewhere here on the forum a long time ago there was a mention that using a power supply with a higher current output could physically damage the Jetson Xavier NX board.

Power Supply Specifications.

  1. PSU included with the Jetson Xavier NX (Liteon PA-1450-26): 19V x 2.37A (RIP);
  2. New PSU for Asus devices (PA-1650-66): 19V x 3.42A;
  3. PSU included with the Lenovo IdeaPad S110 netbook (CPA09-A03): 20V x 1.5A.

P.S. If my thread was created in the wrong section of the forum, please move it to the appropriate section.

Thanks in advance,
Evgeny.

The Jetson Xavier NX Developer Kit Carrier Board Specification (P3509 A01) has the DC power jack information below. The PA-1650-66 is electrically compatible but its barrel length of 12mm leaves some of the outer barrel exposed and can cause intermittent disconnection. For reliable operation, find a power supply with a 9.5mm barrel length to match the bundled unit. There are compatible options available when searching for “Jetson Xavier NX power supply” but I can’t specifically recommend any of them as NVIDIA has only validated the supply bundled with the Dev Kit.
