This document describes the Merlin Flash 4000, a portable power bank designed for charging smartphones and other devices, including wireless charging capabilities.

Function Description

The Merlin Flash 4000 serves as a versatile power bank, offering multiple methods for charging devices. It features two USB output ports for wired charging, a Type-C input port, and a Micro USB input port for charging the power bank itself. Additionally, it incorporates a wireless charging surface, allowing compatible smartphones to be charged simply by placing them on the device. An LED indicator provides real-time feedback on the power bank's charge level and status.

Important Technical Specifications

While specific technical specifications like battery capacity (mAh) are not explicitly stated in the provided manual, the device is designed to charge smartphones and other devices. The LED indicator, with its four segments (100%, 75%, 50%, and 25%), suggests a substantial battery capacity. The input ports (Type-C and Micro USB) are compatible with standard 5V USB adaptors, and the output ports (USB 1 and USB 2) are designed to charge devices efficiently. The wireless charging feature is compatible with smartphones that support wireless charging.

Usage Features

Charging the Power Bank: The Flash 4000 can be charged using either the Type-C or Micro USB input ports. Users can utilize the included cable, their smartphone charger (for Android devices only), or connect it to a computer or any 5V USB adaptor. The LED indicator will show the charging progress.

Charging your Smartphone (Wired): The power bank allows for simultaneous charging of up to two devices via its USB output ports. To charge a device, simply connect the appropriate cable from the power bank's USB port to the smartphone, then switch the power bank ON using the ON/OFF button.

Wireless Charging: For wireless charging, the power bank should be placed flat with its wireless surface facing up. After turning the power bank ON, a compatible smartphone can be placed on top of the wireless surface. It's crucial to ensure the smartphone is placed properly for effective charging. This feature is exclusively for smartphones capable of wireless charging.

LED Indicator: The LED indicator (#5) serves a dual purpose: it shows the remaining charge when the power bank is in use and indicates the charging progress when the power bank itself is being charged. The four LED segments correspond to 100%, 75%, 50%, and 25% charge levels.

Troubleshooting:

Smartphone not charging: For wireless charging, verify smartphone compatibility and proper placement. For wired charging, try a different cable or port, and ensure the power bank is ON.
Slow charging rate: If charging is slow and the LED indicates a low charge, the power bank likely needs to be recharged.
