Plan is to move into predominately wireless charging products as there's no batteries in a wireless charger, not the one I'm going to be selling anyway. Market is UK wide in that instance. Wireless charging will become the norm in the future. Just set your phone down and walk away, job done. As for N.I. customers, 98% of NI population have at least one gadget in the home that needs charging. People using their phones more in the future, battery development not progressing as fast as people want (see iphone owners), means there will be a market for my portable chargers in the meantime. Convenience of just topping up the battery, on the move, is a big factor. Stick the charger on to your phone and stick it in your pocket or bag. Sorted.
