LISEN 140W Dual USB-C to USB-C Cable (3FT Main + 1FT Splits)

- Read Before Use : ① A built-in E-Marker chip inside the aluminum mid-connector safely manages power and temperature (non-removable). To verify with a USB tester: insert only the "IN" end and try both orientations ? do not insert the "OUT" ends. ② For optimal 140W fast-charging, pair with a 140W+ charger (not recommended under 65W). ③ Connect "IN" to your charger, "OUT" to your devices ? reversed connections will not charge. ④ Only the first connected device supports 480Mbps data transfer; dual ports do not support PPS. ⑤ Single port supports PD / PPS / PIQ 3.0; when two devices charge simultaneously, the first plugged in receives priority power based on each device's needs. - Clutter-Free Workspace |140W Simultaneous Dual-Device Charge : Upgrade to a more comfortable, organized work environment and hassle-free travel. This premium 140W cable packing massive dual-charging capability runs your laptop and smartphone simultaneously.

The 0.3m (1ft) split arms keep your setup compact and clutter-free, ideal for devices sitting side by side on your desk. Soft silicone means zero cable tension: your phone stays put, your laptop stays connected, nothing gets dragged around.

Product description

Note

1. The cable supports PD, PPS, and PIQ 3.0 protocols for fast charging when using a single port; dual ports do not support PPS;

2. For optimal charging performance, pair with a 100W+ or 140W+ wall charger to ensure each device reaches its rated fast-charge speed.

3. Connect "IN" to your charger, "OUT" to your devices ? reversed connections will not charge.

4. Only the first connected device supports 480Mbps data transfer;

5. Want to verify the E-Marker chip yourself? Use a USB-C hardware tester (e.g., ChargerLAB Power-Z). Insert only the "IN" connector ? the chip can only be detected from this direction, not from "OUT" connectors. If the first insertion shows no data, flip the IN plug 180° and re-insert; the E-Marker info should register on one of the two orientations.

6. When two laptops are used simultaneously, the first laptop plugged in receives a higher power. The actual power each device receives depends on its power needs
