Joyroom Multi-function USB to USB-C/Lightning/microUSB Cable S-A18 — 2x USB-C, Lightning, microUSB, USB-A

The Joyroom S-A18 multi-function cable connects devices with USB-C, Lightning and microUSB ports to a USB-A source. It combines two USB-C connectors plus one Lightning and one microUSB in a single braided cable, allowing charging and syncing of smartphones, tablets, powerbanks and other small USB-powered devices. The braided nylon construction and reinforced ends are designed for daily use and increased durability.

Advantages

The cable supports a total current of up to 3.5A for faster charging and offers data transfer speeds up to 480 Mbps for file syncing while charging. A built-in smart chip regulates voltage and current to reduce overheating and protect connected devices. Its braided design and reinforced connectors provide durability rated for more than 10,000 bends.

Suitable for

• Charging and syncing smartphones with USB-C, Lightning or microUSB ports
• Powering and charging tablets and powerbanks from a USB-A port
• Connecting multiple small USB-powered devices simultaneously

When it may not be suitable

The cable connects to a USB-A source and is not a standalone power adapter; it requires a USB-A charger, computer or powerbank to provide power. It may not support higher fast-charging protocols that require higher single-device current or specialized chargers beyond the stated 3.5A total.

Key specifications

• Connector types: USB-A to 2× USB-C, Lightning, microUSB
• Total current: up to 3.5 A
• Data transfer speed: up to 480 Mbps
• Construction: braided nylon with reinforced connectors
• Durability: rated for more than 10,000 bends

How to use

Connect the USB-A end to a compatible USB-A power source such as a wall charger, computer USB port or powerbank. Plug the appropriate connector (USB-C, Lightning or microUSB) into each device you want to charge or sync. The cable supports simultaneous charging of multiple devices; ensure the combined power draw does not exceed the 3.5A total. For data transfer, connect one device to the host USB-A port and use the corresponding connector on the cable to transfer files at up to 480 Mbps.

What to consider before purchase

• Requires a USB-A power source; not a charger by itself
• Total current is shared between connectors (max 3.5A)
• May not support device-specific fast-charging standards that demand higher current per port

Usage recommendations

Use a quality USB-A charger or power source that can safely deliver sufficient power. Avoid placing the cable under heavy strain or crushing it to prolong the braided construction and reinforced connector lifespan.
