👉 30W chargers = decent (basic fast charging)
👉 60W+ chargers = 🔥 very fast (similar to wall charging)
🔥 Why Most Car Chargers Are Slow
Here’s the truth:
- Old USB-A chargers = slow
- No Power Delivery = no fast charging
- Fake wattage claims = common problem
👉 What you actually need:
- Minimum 30W output
- USB-C port
- PD (Power Delivery)
❓ FAQ
Is 20W enough for iPhone 17?
👉 Yes, but not ideal in a car environment
What is the optimal power?
👉 30W to 60W
Can I charge multiple devices?
👉 Yes, but power is shared between ports
🔌 Charging Cable (Important!)
We used a USB-C to USB-C PD cable (100W rated)
👉 This is critical. A weak cable = slow charging even with a powerful charger.
👉 🔥 Recommended cable (Amazon)
👉 💰 Cheaper option (AliExpress)
Why it matters:
stable performance under load
supports fast charging protocols
prevents voltage drop
