Thermals and noise in daily use

An intelligent chip and load-break switch provide overcharge, overheat and short-circuit protection. Flame-retardant materials keep the housing cool during typical non-gaming workloads. At 500 g with a slim profile, the adapter stays unobtrusive and silent on a desk or in a travel bag.
