I. Product Core Features

✅ AI Intelligent Recognition, Automatic Power-Off When Fully Charged

Equipped with patented invention and utility model technologies, it accurately identifies the device's battery status and automatically disconnects from the device when fully charged or nearly fully charged, completely eliminating the risk of overcharging. Even overnight charging eliminates concerns about the device being under high voltage for extended periods, extending battery life.

✅ 140W Fast Charging, Dual-Core Protection

The splitter supports 140W high-power output and comes with a 100W braided Type-C to C data cable, compatible with mainstream devices such as Android, Apple, tablets, and laptops. Fast charging protocols are not compromised, maximizing charging efficiency and eliminating charging wait times.

✅ Dual Current Recognition Modes, Adaptable to All Scenarios

White Light Mode: Adapts to screen-equipped devices such as phones, tablets, and laptops in standby mode, accurately capturing standby current changes for error-free power-off.

Blue Light Mode: Adapts to low-current devices such as power banks, small fans, shavers, beauty devices, and toys, offering more sensitive recognition and safe power-off even for small devices.

✅ Physical Power-Off + Safety Protection, Visible Peace of Mind for Charging

Features a fire-retardant PC shell with a memory silicone cushioning pad, ensuring zero scratches and wear during automatic plugging and unplugging; full physical power-off eliminates reliance on device system settings, and safety protection is independent of device permissions, making it safe for the elderly and children.

✅ Durable Braided Cable, More Convenient for Daily Use

The Type-C to C data cable uses a zinc alloy connector + nylon braided outer sheath + PET protective layer, allowing for effortless use over a 1.5-meter distance. Its lightweight 55g design makes it resistant to breakage when bent, convenient for daily storage and car use.

III. Product Advantages

1. Why choose physical automatic power-off?

Traditional charging protection relies on device systems or charger protocols, failing to cut off current at its source. The Coolwajia Full Charge Splitter, however, employs a physical automatic plug-and-unplug design, directly disconnecting the device from the charging cable once fully charged. This prevents the battery from remaining in a float charging state for extended periods, reducing the risk of battery aging and bulging, making it especially suitable for nighttime charging and prolonged plugging-in use.

2. 140W High-Power Compatibility, Unrestricted Fast Charging

The splitter supports 140W high-power transmission. Paired with a 100W fast charging cable, it is compatible with mainstream fast charging protocols such as PD and QC. Phones, tablets, and ultrabooks can all charge at full speed without sacrificing charging efficiency due to protection devices, achieving both fast charging and safety.

3. Detailed Design, Balancing Durability and Device Protection

Fire-retardant PC Shell: High temperature resistant and impact-resistant, not easily damaged in daily use, ensuring safer charging.
Memory Silicone Cushion: Buffers impact during insertion and removal, preventing scratches on the interface and damage to the device during long-term use.

Lightweight Design: The connector weighs only 23.5g, and the data cable weighs 55g, making it portable and space-saving, ideal for daily outings and travel.

IV. Applicable Scenarios and Devices

✅ Daily Overnight Charging: Plug in your device before bed, and it automatically disconnects when fully charged, eliminating the need to get up in the middle of the night to unplug it and allowing you to sleep soundly without worrying about overcharging.

✅ Long-Term Plug-in Devices: Tablets and laptops can be plugged in for extended periods, preventing the battery from being under high voltage for long periods and extending battery life.

✅ Low-Current Device Charging: Power banks, Bluetooth headsets, small fans, shavers, etc., don't need constant monitoring of the charging progress; it automatically disconnects when fully charged.

✅ Car Charging: Forgot to unplug the device after parking? No need to worry; it automatically disconnects when fully charged, preventing battery depletion or overcharging.

✅ Multi-device compatibility: One device is compatible with mobile phones, tablets, laptops, and small appliances, eliminating the need to purchase multiple protection devices.

V. Instructions for Use and Precautions

Mode Switching: Briefly press the separator button to switch modes. A white light indicates a device with a screen, and a blue light indicates a low-current device mode. Select the corresponding mode according to the device being charged.

Usage Steps: First, insert the separator into the device's interface, then connect the charging cable. Confirm that the device has started charging. The separator will automatically power off when fully charged.

Safety Tips: Only supports Type-C interface devices. Do not use with incompatible chargers. If there is any sticking or difficulty in plugging or unplugging, check the interface for foreign objects and avoid forcing the connection or removal.

Error Explanation: Product dimensions are measured manually; slight errors are normal. The actual product shall prevail.
