How to Use

1. Understanding "100%" on your screen: The 100% displayed on a phone or tablet screen does not always mean the battery is completely full. After reaching 100%, devices typically enter a trickle-charge phase for 10–50 minutes until the battery is truly at capacity. The intelligent separator will disconnect once this trickle-charge phase is complete.
2. If the charger disconnects early (around 80%): Some phones have built-in battery optimization features that can interfere with charging detection. To fix this, go to Settings → Battery → Charging and turn off "Battery Optimization".

Frequently Asked Questions

Q: Does this USB-C 140W charger work with all smartphones and laptops?

A: Yes — this USB-C fast charger is compatible with a wide range of USB-C enabled devices, including Android smartphones, tablets, and USB-C laptops. It uses the USB Power Delivery (USB PD) protocol, which is widely supported across major device brands. Always check that your device supports USB-C PD charging for best results.

Q: Does the auto cut-off feature damage my device's battery?

A: No. The intelligent auto cut-off feature is designed to protect your battery. By stopping the flow of power once a full charge is detected — including after the trickle-charge phase — it prevents overcharging, which can degrade battery capacity over time with conventional chargers.

Q: Is a USB-C charging cable included in the package?

A: No, a charging cable is not included with this adapter. You will need to use your own compatible USB-C cable to connect your device to this charger.

Q: What should I do if the charger disconnects before my phone reaches 100%?

A: If your phone disconnects at around 80%, this is likely due to a built-in battery optimization setting on your device. Navigate to Settings → Battery → Charging and disable the "Battery Optimization" option to allow the charger to function correctly.
