The size of this in-car charger is the only negative complaints. Because of its relatively large size, it is likely that it will not be connected to any type of cigarette lighter a little too recessed ... If you're lucky enough to have a cigarette lighter plug that accepts charger, this is the best! 4 USB port and can connect another take on the lighter, what, for example, recharge his phone, connect a GPS to a CB radio, etc ... all on a single socket! A well thought object.
