   Question for EE folks:

   Background: I have two of these LX-2BUPS units. They're basically a mini DC to DC UPS battery pack using 2x18650 cells. Folks have been using them to power old laptops since they can be used while also being charged.

   My question: Can the output of two of these that each provide 5V @ 3A be tied together to provide longer run times?
