FAQ
How do I know when the PowerPort 4 is charging my devices?
When the PowerPort 4 is "slowly charging" or in standby mode (at an output current of less than 500mA), the LED will illuminate in blue. When the PowerPort 4 is "fast charging"(at an output current of higher than 500mA), the LED will illuminate in green.
What kind of USB charging cables should I use with the PowerPort 4?
To ensure the utmost safety and performance, we strongly recommend using your device's original cable (OEM) or a certified third-party cable (MFI) to charge your devices with the PowerPort 6.
What should I do if any port or ports stop working?
If any port or ports stop working, it may be due to a faulty cable, not the PowerPort 4 itself. Try charging with different cables. If the problem persists, please email us at support@anker.com to claim your 18-month warranty.
What if the PowerPort 4's LED is working but my device isn't charging?
