Here are the comments I had written on the 3.1 Amp model RP-CC01 (always available) before receiving the new.
This charger is solid and well finished. Its lacquered black finish does not denote my dashboard. The advantage is that it has two different outputs 1A or I connect my GPS and 2A to recharge smartphone, tablet or external battery. In my car (Ford) runs whenever I insert it into the cigarette lighter (RED light).
Japprécie that even with maximum throughput, these chargers do not heat. I'm very happy and recommend.
Tip: Do not leave plugged in when not in use, it neatly into the ashtray.
