The passport ultra is a nice charger, built-in powersupply and fairly decent spec ( 100watts vs 50watts which most ac/dc chargers are limited to ), but it will only charge on lipo at a time; never seen any complaints about quality. I'd skip the regular passport lipo charger though as it only has fixed charge rates vs fully adjustable settings.

A couple of cheap 50watt DC chargers wouldnt be such a bad setup though if you were only charging 2-3s lipos on each, would still get about 60-80minute charge times at most, then run them both from one large PSU. If you went that route, you can get the chargers for as little as ~$25-40 each with no complaints about quality:

Just a small selection- there are so many chargers like this its overwhelming..
