An iPhone dongle is a small adapter that adds back ports or features your phone doesn’t have built in. Depending on your model and needs, a dongle can:

• Play audio: Connect wired headphones via a USB‑C or 3.5 mm jack.
• Charge + listen: Splitters let you power your phone and use audio at the same time.
• Show video: Output your screen to a TV or monitor via HDMI.
• Use accessories: Plug in USB drives, keyboards, or card readers with a USB adapter.

Match the adapter to your phone’s port (USB‑C or Lightning) and the function you want. Features and performance can vary by accessory.

Start by checking your phone’s charging port and your goal. Then narrow it down:

• Port type: Recent models use USB‑C; older ones use Lightning. Choose an adapter that matches your port.
• Function: Audio (to 3.5 mm), charge + audio splitters, video (to HDMI), or data/USB accessories.
• Specs to review: For audio, look for a built‑in DAC if you want higher fidelity. For charge‑through, confirm the wattage your charger and adapter support. For video, confirm the resolution/refresh rates listed.
• Compatibility notes: Check the product page for supported models and features like mic/call support.

Choosing this way can help you find a compatible dongle without guesswork.

Yes—many 2‑in‑1 adapters let you charge while listening, but capabilities can vary by model and accessory.

• Look for splitters: Adapters that provide a charging port plus a 3.5 mm or USB‑C audio jack are designed for simultaneous use.
• Check power rating: Confirm the pass‑through wattage meets your charger and phone’s needs.
• Audio features: If you take calls, check that the adapter supports inline mics and voice calling.
• Use tip: Plug in power first, then headphones to help devices negotiate power and audio cleanly.

Real‑world results can vary by cable, case, and app, so reviewing the product’s compatibility notes is helpful.

You can mirror or play video using a compatible video adapter and an HDMI cable.

1. Match the port: Choose a video adapter that fits your phone (USB‑C or Lightning) and supports HDMI output.
2. Connect: Plug the adapter into your phone, then run an HDMI cable from the adapter to a TV input.
3. Select input: Switch your TV to the corresponding HDMI input.
4. Power if needed: Some adapters work more reliably when connected to a charger.

Supported resolutions and app playback can vary by phone model, adapter, and content rights. Checking the adapter’s specs and your TV’s HDMI capabilities can help ensure a smoother setup.

You’ll find a wide selection of phone adapters on Walmart.com and in many stores.

• Shop online: Search for “USB‑C to 3.5 mm,” “audio splitter,” “USB adapter,” or “HDMI adapter,” then filter by features you want.
• Check compatibility: Review the product page for supported phone models and functions (calls, video, charge‑through).
• Pickup or delivery: Options may be available depending on your location and inventory.
• Read reviews: Customer feedback can provide insight into real‑world performance.

Inventory and features can vary, so comparing a few listings before you buy can make it easier to pick the right dongle.
