A premium 36W color screen aluminum alloy detachable power bank DIY kit with features like no activation required, no welding needed, tool-free battery replacement, and plug-and-play functionality. Equipped with an Immersion Gold PCB, gold-plated high-current springs, and compatible with multiple battery specifications, its shell is made of 6063 series aluminum alloy, enabling tool-free disassembly and battery replacement via threaded fastening. The bottom features laser-engraved markings (wear-resistant) for compliance with airline and high-speed rail regulations. It supports simultaneous output from three ports, pass-through charging, two bidirectional Type-C ports (36W input/30W output), a 0.96-inch IPS HD color screen for real-time data display, and an NTC temperature control system for safety. The outer shell temperature stays below 45℃ during charging/discharging, with additional functions like long-press to activate low-current ECO mode and short-press to check battery voltage.

Key Features

1. Durable Aluminum Shell: Crafted from 6063 series aluminum alloy, the shell consists of 3 parts—top cover, tube body, and bottom cover—secured by threads for tool-free disassembly and battery replacement.
2. Wear-Resistant Markings: Custom laser-engraved bottom markings (sunken design to prevent wear) ensure compliance with airline and high-speed rail regulations.
3. Triple Port Simultaneous Output: Supports simultaneous output from Type-C1, Type-C2, and USB-A ports (total power not exceeding 15W at 5V peak when all three ports are in use).
4. Pass-Through Charging: Supports pass-through charging (total power not exceeding 15W).
5. Bidirectional Type-C Ports: Type-C1/C2 support bidirectional charging/discharging—36W input (PD 12V3A) and 30W output (PD 12V2.5A), fully compatible with all Samsung/iPhone models (iPhone 16/15/14 series) for maximum power.
6. High-Performance USB-A Port: USB-A supports one-way output up to 18W, with SCP protocol supporting a peak of 25W.
7. 0.96-Inch IPS HD Color Screen: Displays rich real-time data, including charging/discharging status, port activity, battery temperature, and remaining power.
8. Low-Temperature Operation: The outer shell temperature remains below 45℃ during charging/discharging (tested at 27℃ room temperature).
9. NTC Temperature Control System: Enhances safety—automatically shuts down when battery temperature exceeds 65℃ and resumes operation when it drops below 45℃.
10. High-Current Gold-Plated Springs: Positive and negative electrodes use gold-plated springs with a peak current load of 12A.
11. Practical Functions: Long-press the button to activate low-current ECO mode; short-press to check battery voltage.
