The SUNSHINE SS-916 Ultra IP Android Charging Activation is a professional battery activation and charging board designed for mobile phone repair technicians. It is widely used to activate, test, and fast-charge smartphone batteries, especially when dealing with dead or deeply discharged batteries that cannot be charged normally.

This device features a multi-interface design with up to 27 battery connectors, allowing it to support a wide range of Android devices as well as iPhone models (from iPhone 6 to newer series). This makes it a highly versatile tool in repair shops handling multiple brands and models.

One of its key functions is low-voltage activation, which helps revive batteries that have dropped below safe charging levels. Combined with fast-charging protocol support, the SS-916 can quickly restore battery voltage and prepare devices for testing or normal use. It also includes a real-time digital display, allowing technicians to monitor voltage and current during operation for accurate diagnostics.

The tool is equipped with an intelligent automatic identification circuit that detects battery polarity and adjusts output voltage and current automatically. This ensures safe and efficient charging without manual configuration. Additionally, it supports adaptive 9V charging, automatically switching voltage levels when required.

Safety is a major focus of the SS-916. It includes over-current protection, which automatically cuts off power when current exceeds about 2A, preventing battery damage or overheating. The system also helps reduce risks such as short circuits and overcharging, making it reliable for professional use.
