USB cable usams U-Tone SJ344USB01 Lightning 1.2 m braided Power-off 2A fast charging black

usams U-Tone SJ344USB01 is a braided Lightning-to-USB cable 1.2 m long designed for charging and data transfer with compatible iPhone and iPad models. The cable integrates a smart chip that supports an automatic power-off function to stop charging when appropriate, and it supports up to 2A fast charging while also enabling data transmission. The outer nylon braided sleeve and zinc alloy connector shells provide improved durability and resistance to tangling for everyday use at home, in the office or on the go.

Advantages

The braided exterior reduces wear and prevents frequent tangling, while the zinc alloy shell improves connector strength and contact stability. The built-in intelligent chip enables the power-off feature to protect devices and batteries by stopping current flow when charging is complete or conditions demand it. The cable supports 2A charging for faster replenishment of battery compared with standard 1A cables and includes a soft indicator light to make night-time connection easier. The 1.2 m length balances flexibility and convenience for typical charging scenarios.

Suitable for

• Charging iPhone and iPad models with Lightning port at home or office
• Connecting Lightning devices to USB power adapters, power banks or computers for charging and data sync
• Everyday use while travelling, commuting, or at a desk where a durable, tangle-resistant cable is needed

Key specifications

• Connector type: Lightning to USB-A
• Cable length: 1.2 m
• Maximum charging current: up to 2A
• Exterior material: nylon braided sleeve
• Connector shell material: zinc alloy
• Features: intelligent power-off chip, soft indicator light, data transfer capability

How to use

Connect the USB-A end to a compatible USB power adapter, power bank or computer USB port and insert the Lightning connector into the device. Charging begins automatically; the intelligent chip monitors the charging process and will cut power when the power-off condition is reached. Use the soft indicator light to confirm connection in low-light conditions. For data transfer, connect both ends to the host device and the Lightning device, then manage files through the computer or device interface.

Usage recommendations

To extend service life, avoid sharp bends at the connector ends and store the cable loosely coiled. Use with chargers and power sources that match the device manufacturer’s guidelines. Inspect connectors periodically and keep them free from dust or moisture. For the best charging performance, ensure the connected power adapter can supply sufficient current (up to 2A) and use original or certified charging equipment when possible.
