Something most chargers were lacking is enough ports and enough power. This solves it all. I can have 3 ports charging at one time, and all at 2+ amps. That's a faster charge for every device. I always walk around with at least a work phone and a personal phone.. So my passengers never can charge since i was using a dual port. But now with a trio of ports, that solves the problem. The device is great and allows me to use my power port in the car efficiently and effectively.
