The size of the barrel plug appears to be standard 2.1 x 5.5mm x 10mm length, commonly used on Linksys and other brands of wifi routers.  It was discovered several EA6350 v3 were susceptible to intermittent power loss when using variety of 3rd party power adapters. The problem was traced to style of 2.1/5.5mm barrel plug. Ensure the replacement power adapter is fitted with the fork/prong sprung style plug as shown below.
