QUICKSTART INSTALLATION GUIDE FOR SMART CHARGING PORT
Introduction:
Your vehicle may already have a USB charging port, but unfortunately many are anemic when it comes to amperage (e.g. 00mA). This compact “Smart charger” is optimally tuned depending on the connected device. You always have the most optimal charging current for a fast and safe charging process because the output adapts exactly to the demand of the device battery making the charging process particularly efficient. Supports BC1.2, QC2.0, QC3.0, PE1.1, PE2.0, FCP, SFCP fast charge protocols (Apple, Samsung, Huawei*, etc.) Custom install in a convenient location and discover how this USB charger would be a massive improvement over the cars built-in charging ports or anemic aftermarket charging port you may have already installed.

Requires only a 2-wire connection. Remove radio or access panel to car wiring.
To operate only when car is running:
Tap RED wire to vehicle 12V ACC supply
To operate at all times:
Tap RED wire to vehicle 12V Battery supply
Connect the BLACK wire to vehicle ground or to radio chassis.

A. Flush – requires drilling a 13/16” hole
B. With Support bracket (mount USB terminal wherever your installation
demands without drilling)
