I have a box that specifies 5V and 2.5A.
I have a plug that gives 5V and 2.0A.

If I hook the two together will I see the explosion? What are the chances that my box will work?

Uhm... maybe it's the missing details? Your "box"? What is it? –  slhck Jul 18 '11 at 19:19

Your power supply will struggle to cope but what actually happens will depend on its exact design - it may:

  • Just not work
  • Overheat
  • Shut down after a while
  • Blow an internal fuse
  • Provide limited current to your device, which may affect its operation
  • Just about work but get hotter than normal

If it were my setup I'd be looking for another power unit
