GLK-UC2X - Power Supply (AC to DC adapter)

My company is preparing to purchase 45-50 of the GLK-UC2X units for a client. I am wondering if there is a place, or way to buy 3-5 spare (Emergency Stock) of the AC to DC adapters? This would be helpful from a support perspective.
Great products, thanks.
