We traveled in S6... Very very old sleeper coach... oldest I have seen in the recent times. Forget about charging points, there is no side table which is common now in most of the sleeper coaches. I think they are removed so there is patch work. There is a patch work on & under the berths too.. The coach itself was very un-hygienic. Rats & cockroaches roaming freely. Dirty all together right from the toilets to seating.
