Frequently Asked Questions

Q: Does this 140W USB-C auto power-off adapter work with my MacBook or laptop?

A: Yes! This smart charging separator supports up to 140W passthrough with PD3.1/3.0 and QC4+/3.0 compatibility, making it fully compatible with MacBooks, ultrabooks, gaming handhelds like Steam Deck, and any USB-C laptop. It will not slow down your charging speed.

Q: Do I need a special cable or charger to use this adapter?

A: No special accessories are required. Simply place this inline adapter between your existing USB-C cable and charger. It acts as a smart bridge and does not replace your cable or charger — both are needed to operate it.

Q: How does the auto power-off feature protect my battery?

A: The adapter uses AI-powered current recognition to detect when your device is fully charged. Once full charge is reached, it physically disconnects the charging circuit, achieving true zero standby current. This eliminates trickle charging and heat buildup, which are the primary causes of long-term battery capacity loss.

Q: What is the difference between White LED mode and Blue LED mode?

A: White LED mode is optimized for screen-based devices such as smartphones and laptops, which have more complex charging profiles. Blue LED mode is designed for non-screen electronics like power banks and small fans. You can toggle between the two modes with a single button press.
