charger feedback, buying tomorrow

looking to get a charger tomorrow. I am interseted in two chargers. The hyperion 720i and this new one by dynamite, it is called the dynamite passport ultra. I will most likely be charging 4s 5000 hyperion packs. Any opinions would be greatly appreciated. Also most of my charging will be done with 110 house pwr. kinda why I like the ultra because it does ac/dc.
