ll chargers does the same thing. All depend on mah's you re pushing. all on you! only differance is cosmetically. How the box looks. I use 2 Ultra Power UP 120AC & Up240AC. One 12amp, the other 24amps. My cars run 6K lipos, I can charge 4 lipos at one time useing both ports in parallel. 240 charger can use for cars also, but used for my Airplanes & Jets. 24amps. I still havent used them to the max, but it does what I wanted them to do after 4yrs. UP120AC you cant get one on Amazon at $120, The UP240AC can find them $180-220. It depends on your need.
