Seen on eBay, three Apple USB chargers, including one transparent.
The first is a 5W American model, in white, listed for $120.
The second is a 20W USB-C model, in its American version. It is transparent, which is rarer (but common among prototypes). It is also listed for $120.
The last is a 29W USB-C model from the first MacBook in 2015. It only offers two voltages, which is quite surprising (5V and 14.5V).
The 14.5V is typical of the first MacBook
