Available variants and package contents:
White Kit: white case, charging module, USB-A to USB-C cable, connection wires, button, screws, and assembly pads/strips shown in the product photos.
Black Kit: black case with the same kit components as the White Kit.
Only Module: one charging module and two connection wires. Case and USB cable are not included with this option.
Batteries are not included with any variant. Assembled-product photos illustrate the finished result.
Assembly requirements:
This is an electronics assembly kit, not a ready-to-use power bank. Installation requires experience with lithium-battery electronics and soldering.
Follow the supplier's assembly instructions, observe the marked battery polarity, and use the specified parallel battery configuration, never a series connection. Incorrect wiring or inadequate insulation can damage the circuit and create a safety hazard.
Test the module and all charging functions before closing the snap-fit case. The case is not intended for repeated disassembly.
