What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title and feature text claim a 20W plug with a 2 m USB-C to USB-C cable, while the contents fields name only a USB cable. Electrical details list 12 Volts output and 3 Amps alongside 20 watts, and the plug is described as both Type G and 2 pin. Verify the supplied kit, plug and output specification for the selected listing before purchase. The listed compatibility includes future or varied device models, which is a seller claim rather than independent confirmation.

Customer feedback highlights positive impressions of adapter quality and charging speed, with the summary saying some customers found it as quick as an Apple original. That may matter to buyers seeking a compact one-port USB-C setup, but reported impressions do not verify charging performance or resolve the listing’s unclear output and kit details. The aggregate rating is mostly high, though a small minority of ratings are low.
