What is the difference between the Circle-K and Lawson Power Cube?

What is the difference between the Circle-K and Lawson Power Cube? - Picturesque scenery of high waterfall falling in water stream between  rocky mountains

Both of these Power Cubes have the same description:

Enhanced Power Cube that provides large XM storage and automatically recharges Scanner until exhausted.

My Questions:

  1. Is there any difference between these two power cubes?
  2. How much Power is initially provided?
  3. Is the "automatically recharged" XM limited by time or by XM amount?
