The D808 famously charges via USB-C. The schematic detail for the TP4056 charging IC will show:

The XHDATA D808 is a widely praised portable shortwave receiver known for its sensitivity and DSP-based architecture. However, the manufacturer does not publish service documentation. This paper synthesizes available teardown data, component identification, and traced partial schematics from online reverse-engineering efforts. It presents a verified block diagram, lists key ICs, and directs researchers to the highest-quality known resources—including 300+ DPI PCB scans and manually traced circuit fragments.
