This 21700 power bank utilizes battery retaining clips, though soldering is also feasible; the cover may be secured with screws, though this is optional.

Figure 4 illustrates the power board design.

On 2025.02.21, updated files incorporating a small board with USB-A and USB-C ports were added, allowing for personalized selection.—My gratitude to @zjw老哥 for the motherboard support.

STEP and Zhongwang 3D source files have been uploaded for convenient modification.

Requires a 21700 battery.

Type-C 3.1A charging board.

M2x4 screws (optional).

(Due to potential variations in material shrinkage, screw holes may require minor adjustments; a screwdriver can be used for slight enlargement.)

This project is a reconstruction of D3falt's design, released as an editable version to cater to individual preferences.
