fast charging charging compartment intelligent 4-in-1. Automatically detect Pro 2/ Pro batteries (mixable). Charge, discharge, charge, store. Quickly charge 2 batteries at the same time. 0.96-inch OLED screen. 24W total charging power. Dual-channel fast charging butler, mobile power converter, charge collector, and battery storage box Unparalleled , 0.96-inch clear OLED screen, displaying all battery and charging information. The fastest charging speed, carefully designed optimization algorithm, dynamically allocates charging power to charging channels, charging faster. Mobile power mode, bidirectional charger design, can not only charge your Pro 2/ Pro/ battery, but also charge your mobile devices when needed. Charging voltage accuracy is critical to battery life, safety and user experience. If the charging voltage is too high, the battery be overcharged; overcharging the battery shorten the battery life at best, and endanger charging safety at worst. If the charging voltage is too low, the battery cannot be fully ; long-term undercharging cause the battery fuel gauge to be unable to calibrate and provide reliable power information. The ultimate customizable experience provides 6 adjustable parameters to meet the advanced requirements of PRO users. It also provides extremely high playability. Pro 2/ Pro/ automatic battery detection. Intelligent algorithm can detect the chemical characteristics of Pro 2 (4.48V) and Pro/ (4.40V) batteries, use different charging curves for different batteries, and support mixed charging Operating environment temperature: 32 to 104℉ (0 to 40℃) Charging power limit (each channel): Up to 15W adjustable Charger mode USB-C input: 5V 3A; 9V2.7A; (max 24W) Mobile power mode USB-C output: 10.5W (5V2.1A) Charging time at room temperature: Tested with a (unaged) Pro 2 1800mAh 4.48V battery * : 10W charging power, from 0% to 80% in 40 minutes; 10W charging power,
