HOYULLI Lightning to USB OTG Adapter with 3.5mm Jack

HOYULLI zoyuzan is a compact Lightning-to-USB OTG adapter that adds a 3.5mm headphone jack, USB-A port for cameras and drives, and passthrough charging so iPhone and iPad users can connect audio, accessories, and storage.

This multiport dongle converts a Lightning port into three practical connections: a USB-A female OTG port for cameras, flash drives, keyboards and MIDI devices; a 3.5mm AUX jack for earphones; and a Lightning charging input so you can charge while using accessories. Designed for broad compatibility, it supports enhanced file import/export on iOS 13 and basic one-way media transfer on earlier iOS versions, while offering plug-and-play convenience for everyday tasks.

How does this adapter help transfer photos and videos between devices?

The USB-A OTG port lets you plug in cameras, SD card readers, or USB drives to move media to an iPhone or iPad. On iOS 13 and later you can import and export files via the Files app; on iOS 9.2–12 the adapter supports one-way transfers into the device.

• Import photos and videos directly from cameras and USB drives.
• Use the Files app on iOS 13+ to move MP3s, PDFs, and documents both ways.
• Plug-and-play—no additional software required for basic transfer tasks.

Can I listen to wired headphones while charging my iPhone?

Yes—this dongle includes a 3.5mm audio jack plus a Lightning charging pass-through so you can stream music while charging. Note that phone call audio via the 3.5mm port may not be supported, so it’s best suited for music and audio playback.

• Simultaneous audio playback and charging without adapters stacked together.
• Works with standard 3.5mm earphones for music and media apps.
• Phone-call audio may be limited—optimized for listening, not telephony.

Which USB accessories are compatible with the OTG function?

The adapter supports a wide range of USB-A devices: keyboards for faster typing, USB flash drives for storage, cameras for media import, and musical gear such as MIDI keyboards and digital pianos. Some advanced features—like mouse and two-way file management—require iOS 13 or later.

• Keyboards and wired mice (mouse functions enhanced in iOS 13+).
• MIDI keyboards, digital pianos, and guitar interfaces for on-the-go music work.
• USB flash drives and camera connections for media transfer and backups.

Is setup difficult and what iOS versions are supported?

Setup is simple: plug the Lightning connector into your device and attach a USB-A device or 3.5mm earphones. It’s plug-and-play for most uses; full bi-directional file sharing and extended peripheral support are available on iOS 13 and newer, while iOS 9.2–12 supports one-way photo/video import.

• No app required for basic use—connect and go.
• iOS 13+ unlocks expanded Files app compatibility and device support.
• Backward compatibility for common import tasks on iOS 9.2–12.

Who is this for? The HOYULLI zoyuzan adapter is aimed at mobile creators, travelers, and multitaskers who need wired audio, simple charging, and direct USB connections without carrying multiple dongles. It’s useful for photographers importing camera footage, musicians connecting MIDI gear, commuters who prefer wired earphones, and anyone who needs occasional keyboard input or USB drive access on iPhone and iPad. If you rely on your mobile device for content capture, productivity, or audio playback and want a compact, all-in-one connector, this adapter simplifies your setup.
