Description
The Single 18650 Li-Ion Battery Power Bank Case is a sleek, compact, and economical portable power solution designed to turn a spare 18650 lithium-ion cell into a pocket-sized emergency charger. Featuring a durable aluminium body with a stylish powder-coated matte finish, this enclosure houses a single removable 18650 battery, providing a stabilized 5V DC output (up to 1A) via a standard USB-A port.
Equipped with an onboard charging and discharging circuit, it serves a dual purpose: functioning as a portable power bank for your microcontrollers, development boards, and smaller electronics, while also acting as a standalone battery charger via its Micro-USB input port. Built-in LED indicators show clear status feedback for both charging and discharging states.
Caution & Note: Pay strict attention to battery polarity during installation; placing the battery the wrong way will permanently burn the internal circuit. Note that this module does not include overcurrent protection (draw current should not exceed 1A). Colors are shipped randomly based on stock availability. 18650 battery is not included.
