Pros

  • Compact design that is noticeably smaller and more traveriendly than traditional chargers, with folding prongs adding to portability.
  • Delivers strong and consistent power, including a full 100W output on the main US port, supporting demanding devices like MacBooks and power banks.
  • Dual US ports allow simultaneous charging of a laptop and another device without reducing performance significantly.
  • Reliable USB Power Delivery (PD) 2.0 compliance ensures compatibility with a wide range of laptops, tablets, and phones.
  • Solid, weluilt construction with no loose parts, and it stays securely plugged into outlets without wobbling.
  • Stays cool during use and avoids overheating even when all ports are in active use.
  • Supports wide input voltage (1040VAC), making it suitable for international travel with a basic plug adapter.
  • Charges MacBook Air M3 and other newer devices effectively, delivering true 100W power on the primary US port.
  • Offers clear charging indicator lights and some surge protection for peace of mind.
  • Works better and charges faster than many original brand chargers, with support for various device types including iPhones, iPads, Samsung phones, and Framework laptops.

Cons

  • Does not support PPS (Programmable Power Supply), meaning it lacks compatibility with newer fasharging protocols that some devices use.
  • US and secondary USB-C ports provide lower maximum power outputs (12W and 18W respectively), which may slow charging of some devices compared to the main USB-C port.
  • AC outlet prongs have been reported as loosely fitted or improperly spaced, causing potential instability or poor connection in some wall outlets.
  • To fully use the charger’s top power capacity, a higuality USB-C to USB-C cable must be purchased separately.
  • Some devices, like Samsung phones, won’t achieve superfast charging speeds with this charger.
  • Works better on power strips or lower outlets rather than directly plugged into certain wall outlets due to prong fit issues.

Bottom Line

The Amazon Basics 100W Four-Port GaN Wall Charger is a compact, reliable, and efficient charger that handles multiple devices at once while delivering true 100W power output on its main USB-C port. It’s ideal for travelers and users needing to charge laptops alongside phones or tablets without bulky adapters. However, if you require the latest PPS fast-charging protocol or need flawless outlet prong fitment, this may be a drawback. For a straightforward, durable charger with great value and compatibility across many popular devices, this is a solid choice — just be prepared to invest in a good USB-C cable separately. If PPS support or better outlet prong design is important to you, you might consider chargers from brands like Anker or others that explicitly feature those capabilities.
