The Core SWX PB-LTK is a Powerbase Edge Lite bundle that comes with the PBE Lite and the PB70C15US p-tap charger.
The Powerbase Edge Lite is the ideal pack for those already invested in the Powerbase system or those that don't utilize the v-mount connection and want a "base" pack only. Similar to the original Edge, the Edge Lite has nearly all the features of the Edge minus a runtime LCD and the aforementioned V-mount connection.
The single channel powertap charger, PB70C15US, charges any of Core's battery packs through the powertap port on the battery while providing a quicker charge current at 1.5A, which is 50% faster than the original PB70C. The charger has LED indication on the front which changes from red to green when fully charged.
The PB70C15US is only for US plugs, and it is not interchangeable.
