This power bank spring kit offers a practical foundation for creating a custom portable charging solution. Designed for DIY enthusiasts and repair technicians, it provides the housing and basic electronics needed to assemble a functional power bank using your own 18650 lithium-ion cells. The kit is supplied without batteries, allowing you to select cells that meet your capacity and performance requirements. With a 10W charging output and multi-U port connectivity, it delivers reliable power for everyday devices.

Features and Construction

The kit combines a lightweight plastic shell with a cylindrical aluminium case designed to securely hold a single 18650 liquid lithium-ion battery. The housing is available in black or white, both supplied as shell and board without batteries.

Material and Build

The outer shell is made from durable plastic, providing a lightweight enclosure that protects internal components. Inside, a cylindrical aluminium case offers a rigid structure to house the 18650 cell, ensuring stable contact and heat dissipation.

Size and Practical Fit

Measuring just 45 x 76 x 22mm, the compact form factor makes it suitable for portable use or fitting into existing equipment enclosures. The small footprint does not compromise the multi-U port output layout.

Uses and Placement

This spring kit is intended for integration into custom power bank builds, replacement enclosures, or electronic repair projects. Its open design lets you select your own battery and use it in various contexts.

Event or Professional Use

Technicians and makers can use it to refurbish old power banks or create custom units with specific battery capacities. The multi-U port output supports simultaneous charging of phones, tablets, or other USB-powered devices.

Everyday Home Use

For home users, the kit allows building a backup charger for travel or emergency situations. The 10W charging power is adequate for topping up a smartphone or small electronics overnight.

Benefits and Buying Value

Choosing this spring kit lets you control the battery quality and capacity, reducing waste by reusing existing 18650 cells. The modular design simplifies future repairs or upgrades.

Reuse and Low Maintenance

Because the batteries are user-replaceable, you can swap in fresh cells when old ones degrade, extending the power bank's service life without replacing the entire unit.

Why Choose This Product

It offers a cost-effective way to build or repair a power bank with standard 18650 cells, giving you flexibility over cell type and capacity. The multi-U port output and 80% conversion rate ensure efficient energy transfer.
