The HyperGear Dual USB 3.4A Mini Car Charger is a compact, portable, low-profile charger that plugs conveniently into your vehicle's power outlet, and provides 3.4A of total charging power. The top port is optimized for charging a smartphone, as it provides a maximum of 1A. The bottom port provides up to 2.4A of power for fast charging a smartphone or tablet. You can charge two devices simultaneously, each port outputting its maximum power to each device. A handy, built-in LED lets you know the charger is working, and provides some extra light when trying to connect cables in the dark.
This charger features advanced circuitry and smart chip technology to maximize charging while keeping your devices safe. The smart chip can determine the maximum current your device can receive, and adjust its output to match (max. power will vary based on the selected port). Internal circuitry protects against damage from short-circuits and overcharging.
