The Acefast A78 is a 20 W GaN charger with USB-C and USB-A ports, created to combine modern devices and accessories with traditional connections through one adapter. Its compact body and distinctive texture make it easy to recognise and suitable for home, office or travel use.

Two connections for an easier transition

The USB-C port serves current equipment while USB-A keeps existing cables and accessories useful. This combination avoids replacing an entire charging setup at once and makes it easy to alternate between a phone, headphones, watch or power bank with one charger.

A compact design with personality

The geometric-inspired surface improves grip and visually distinguishes the adapter from other chargers. Its contained format is easy to store and helps make better use of the space available around wall sockets and power strips.

GaN technology for everyday charging

Gallium nitride supports efficient power conversion in a small body. The charger adapts delivery to compatible devices and brings together practicality, portability and connection flexibility for regular charging without unnecessary complexity.

Who is it recommended for?

It is a suitable choice for users with a mixture of USB-C and USB-A cables who want a single compact adapter. It also works as a spare charger for work or travel and for anyone wishing to extend the useful life of current accessories.
