Q: Is the LED just for decoration?
A: No! Indicates charging via:Off (unplugged, charged <0.12A, or at ~80% smart charge cutoff); 2 light strips slow chase (5V slow/trickle charging); 3 light strips fast chase (9V fast charging); 4 light strips fast cycle for 12V-48V PD fast charging.
Q: Why does the LED stay on after full charge?
A: Normal! After full charge, some devices stop charging (current <0.12A, LED turns off), while others enter standby/trickle mode (current =0.12A, LED shows slow chasing) to maintain battery health – this varies by device, not a defect.
Q: Does it have E-Mark chips?
A: Yes! Equipped with HUSB332G E-Mark chips, certified for 240W PD fast charging to ensure safe, stable power and overcurrent/overvoltage protection.
Q: Compatible with USB-A chargers?
A: No, designed for USB-C to USB-C. Use a USB-C PD charger for fast charging; USB-A setups need an adapter (not included).
