Mike has several mobile devices and would like just one charger that can handle all of them. Leo says that the Charlie Charger does that. It's a commercial charger that handles up to six phones. Unfortunately, with Charlie Charger the more devices he connects, the more the amperage drops.
Mike needs one that can devote a certain number of amps to each port. Scosche makes a 10 amp charger, giving two amps for each of the 5 ports, which should work great for Mike.
