What amps are required in a vehicle

My car has two 12v outlets, 1 x 1amp and 1x 2.1 outlet, so I assume its the higher one that is needed for my Tom Tom Start 20 but can you confirm this.

    Hi there @PaulG1957 -

    Do you mean that your car has 2 USB outlets? These are rated at 5 volts. If that is the case, then either USB port will be safe to use, but the higher rated one is better used for charging higher current usage devices ie. iPad.
