4 Cellphone chargers into 1?

Recommended Posts

good nyjumpee,

it calls for 2.6 amps if all the items are to be charged same time

you will perhaps have problem once the sigle proposed charges goes faulty--- redundancy would be better
you may try to develop a psu with 5.0 output and a current capacity of atleast 3 amps -- may be LM317 with a  pass transistor for current boost. Set it for 5V and locally rig up a multiway usb sockets and wire them with only +5 and return wirs at the appropriate pins-- logically it should work-- how ever i agian suggest , think interms of redundancy

Li-ion chargers might not like parallel power, them dent to "sniff" input voltage to vary PWM cycles for proper regulation. And when theres a few PWM regulators, it may cause too much noise that will mixup error amplifiers of such chargers to undetermined state. ie. charger doesn't work like it should be.
