## What is White Lightning SmartGPU?

The White Lightning SmartGPU™ App is a companion for the White Lightning SmartGPU™ and allows users to monitor the external power supplied to their airframe from inside the cockpit through a bonded & secure Bluetooth Low Energy connection, instead of needing to be in the line of sight of the display panel. A compatible White Lightning SmartGPU™ is required for use.


+Application Features:
- Displays real-time Input/Output Voltage and Current readings
- Provides supply health and performance metrics through temperature readings.
- Remote pause/resume control of output voltage

The White Lightning SmartGPU™ is unique with its advanced user interface, remote operation and control via a mobile device app, and its option for full-time battery maintenance charging.
