hyperion charger and power supply

Just wanted to know,i have a hyperion charger the eos606i.can i use a power
supply with this charger to charge my lipo batterys with.i am using true rc
4s 14.8 4000mah.it can only charge a about 3 amps,and it takes about and
hour and a half to charge.takes to long for me.i know it is ac/DC but will
this work? any help dont want to destroy my batterys.

the 0606i does have DC inputs but it wont matter the charger can only output 50 watts, if you want a faster charge you will need to buy another charger

Running a 12V PS might only take 1-2 minutes off your charge time, not worth buying unless you plan on getting a 12V-only charger in the future, best bet is to sell the charger you have, and upgrade as azjc said.
