USB‑C Audio Solutions

Grab USB‑C earbuds from Samsung, Belkin or Apple for $20 or less. If you have 3.5 mm headphones, a USB‑C DAC lets you plug them directly into your phone. Apple’s version costs about $10; iFi’s higher‑end models run around $50 and improve sound quality.

USB‑C Endoscope

A flexible cable with a tiny camera and LED ring plugs into the USB‑C port and turns your screen into a live window. Use it to inspect drains, walls, behind appliances or any tight space.

  • 16.4 ft cable length
  • IP67 waterproof rating – can be submerged
  • Works with both iPhone and Android

USB‑C Flash Drives for On‑the‑Go Storage

When cloud backup is slow or expensive, a USB‑C flash drive is the low‑tech fix. Dual‑connector drives (USB‑C / USB‑A) work in phones, laptops and Macs without adapters.

  • Samsung model: up to 400 MB/s, $26 for 64 GB
  • SanDisk model: 256 GB for about $45
  • Allows 4K video recording directly to external storage

USB‑C Video Output & Docking

Travelers can connect a $15–$40 HDMI or DisplayPort adapter (Anker, Belkin) to stream to hotel TVs. Samsung Galaxy users can enable DeX mode for a desktop‑like experience with resizable windows and a taskbar.

USB‑C Thermal Imaging Camera

FLIR’s thermal camera plugs into the USB‑C port and shows a color‑coded heat map on your phone. Use it to locate drafts, check attic insulation or monitor hot outlets.
