Key Features

• Case Compatibility: The charger body is slim enough that it won’t block adjacent outlets on most power strips.

• Intelligent Chipset: Automatically adjusts the current to match your device’s needs (e.g., it will slow down for AirPods or Apple Watch to protect their smaller batteries).

• Safety Suite: Includes a dynamic temperature sensor that monitors heat and a PMW (Pulse Width Modulation) chip to manage power flow and prevent over-voltage.

• Build Material: Made from UL94-V0 rated fireproof PC (polycarbonate) with a scratch-resistant matte finish.

Performance Expectations

• iPhone 12–15: 0% to 60% in roughly 30 minutes.
