turnigy accucel charger problem

[ph678]

Ive recently bought this charger and for whatever reason it cuts out intermittently. I could be putting my 6s into storage or charging a 3s for my 250 and it just powers off sometimes. Im using a 6a power supply and i never run it at its limits but i'll come to checking on it and its powered off!
has anyone comes across this problem at all?

Never had that mate. Mine is VERY fussy on input voltage, but I don't remember it just shutting down.
