charging station 3: some of the stuff i've fit in it. i used a large surge protector and a small surge protector. i have three eGo chargers, 2 riva 510 chargers, a black and decker vpx powerpak charger and the charger for the provari shown. i have room for at least one more provari sized battery charger, and a couple of more smaller chargers. sometimes i also charge my iphone here.
