22.5W DIY Power Bank Kit with TFT Display & Fast Charging

This DIY power bank kit features a 22.5W bidirectional fast charging mainboard compatible with multiple mainstream protocols including PD, QC, and Apple fast charging standards. It supports simultaneous output via one Type-C port and two USB ports, enabling quick charging for various devices.

Designed for tech enthusiasts who want a customizable power bank, it provides efficient and stable current and voltage outputs to ensure reliable device charging.

The module includes quadruple intelligent protections against overcharging, over-discharging, over-voltage, and overheating. These features safeguard both the batteries and connected devices, minimizing risks during operation.

• Built-in protection eliminates need for separate protection board
• Supports high conversion efficiency and stable electrical parameters

A real-time color TFT screen displays key parameters such as remaining power, voltage, and temperature. This visual feedback helps users monitor battery status at a glance, enhancing user experience.

• Accurate power indicator with intelligent self-learning
• Screen requires careful handling due to fragility

Designed to accommodate two 1260110-type 3.7V lithium-ion cells (batteries not included), batteries must be soldered in parallel for safe operation. Lithium iron phosphate batteries are not compatible. The protection circuit on board simplifies assembly by removing the need for an external protection board.

Careful assembly is essential: avoid reverse polarity to prevent damage, ensure proper insulation of battery wiring, and secure batteries inside the casing to avoid rattling or collapse. The snap-fit casing is intended for one-time assembly after thorough testing.
