Compact, Durable Design
Crafted from high-quality materials, this DIY power bank case offers durability in a compact, sleek shell that's easy to assemble and carry.
Its exquisite appearance enhances your DIY project with a professional finish.
Versatile Charging Ports
Equipped with two USB output ports: one 5V-1A and one 5V-2A, allowing simultaneous charging of devices with different power needs.
A micro USB input port (5V-1A) is also included for recharging the power bank itself.
User-Friendly Controls and Indicators
The power motherboard features a 'one-button control' switch to display power levels via four LED indicators representing 25%, 50%, 75%, and 100% charge.
Long press switches the LED flashlight on or off, while double-clicking turns off the output to cut current flow for safety.
Safety and Installation Notes
Ensure correct battery polarity to protect against damage, as incorrect installation can burn the board.
Test battery function before installing the shell to avoid damages during assembly or disassembly.
