Working Condition: 3rd Generation iPod with Homemade AC Adapter

This is a rare 20GB model of the 3rd generation iPod (Dock Connector).
It's a unique model among all iPods, with all buttons and the wheel being touch-sensitive. As it's a product from over 20 years ago, few units still function properly.
The 3rd generation can connect to a PC via USB, but it cannot charge or supply power. Therefore, I will include a self-made AC adapter for charging.

It works without any problems, and the battery is still alive. I measured it to last 7 hours from a full charge, but the degree of degradation is unknown.
Also, as it's an early iPod product, it has significant self-discharge even when not in use. Please be aware that the battery drains easily because the HDD spins constantly when connected to a PC.
The exterior has some scratches, but it's in good condition with few scratches for an old product.
Also, the screen display is faint and difficult to see by default, so please adjust the contrast.

Although it works without any problems, this is a release of an old collector's item, so please understand it as a vintage item.
Instant purchase is possible, but I will not offer a discount.
