Teardown: CukTech No.6 Power Card Air — Ultra-Thin Card-Form Fast Charger
2026-08-14 · Compiled by Best IT Parts from public industry reporting
CukTech has launched the No.6 Power Card Air, a charger built around an ultra-thin card-form design. This teardown opens the device to reveal how a full fast-charging circuit is packed into a body slim enough to slide into a wallet. The article walks through the internal layout — compact PCB with high-density components, the switching power stage, transformer and synchronous rectifier selection, and the thermal measures required to sustain output in such a constrained enclosure — along with the connector and foldable plug design. It also references CukTech's earlier 90W card-form charger to show how the form factor has evolved. For charger OEMs, power adapter wholesalers, and component buyers, the teardown is a useful reference on ultra-thin power supply design, PCB miniaturization, and thermal engineering in pocket-sized charging products.
