I have 2 different models of the same device. The old model is not receiving power from its power source which is the following power pack:

Old Model's Adapter

I want to test another power pack to see whether the issue is with the power source but I don't have an identical power pack. This is the power pack that came with the new model of the device:

New Model's Adapter

Based on the electronics information on these power packs, would the new model's adapter be compatible with the old model device?

The second model of the Power Supply appears to be rated at half the power of the first model as per the specifications (i.e. 60W v/s 30W respectively). I'd say its not adequately rated.

  • \$\begingroup\$ If I were to connect the second power pack to the device that the first power pack came with, is the worse case scenario that the device just won’t receive sufficient power? \$\endgroup\$ – Guru Josh Mar 8 '18 at 10:42
  • \$\begingroup\$ Yep! That's correct. \$\endgroup\$ – Speculator Mar 8 '18 at 11:07

    \$\begingroup\$ @Speculator surely the worst case is that the power supply overheats, catches fire, and burns the house down. \$\endgroup\$ – Simon B Mar 8 '18 at 15:58
  • \$\begingroup\$ @SimonB That’s my question. What happens if you use a power pack that is rated to a lower amperage? \$\endgroup\$ – Guru Josh Mar 9 '18 at 21:15

    \$\begingroup\$ @GuruJosh If it's well-designed, it will shut down and refuse to work. If it's cheaply designed, it will overheat and fail. \$\endgroup\$ – Simon B Mar 9 '18 at 21:25
