What is a good / best value of

(battery final charge x voltage) / (fixed mains power used x charging time)

one can expect from a good #LiFeO4 charger ? I am not worried about details of charging schemes but the wallplug efficiency, for an ideal charging cycle, set by the e.g. thermal lossiness of the components of the AC mains charger. Which #charger is the best in this fundamental respect ? #speichern #wirkungsgrad #efficiency #batterychargers
