USB-C Adapters: The Game-Changers
- Charge your MacBook (100W)
- Connect a 4K monitor (via DisplayPort Alt Mode)
- Transfer photos from a USB-A camera
When to Stick With Legacy Connectors
- USB-A: Ideal for older desktops, printers, or budget chargers (still 45% of legacy devices).
- Micro-USB: Common in IoT gear (smart cameras, Bluetooth speakers) due to low cost.
- Lightning: Required for pre-2023 iPhones—but Apple now uses USB-C (thanks to EU rules).
The Bottom Line: Invest in USB-C Adapters
- Reduce clutter: Ditch 5+ cables for one.
- Save money: Avoid buying new chargers for every device.
- Stay compatible: Use USB-C hubs to connect old USB-A/Micro-USB gear.
