Anker Prime 240W GaN Desktop Charger (4 Ports, A2342)

Chargers

This is what matters about Anker Prime 240W GaN Desktop Charger (4 Ports, A2342).

About

A PD 3.1 EPR desktop unit with a detachable base for vertical desk mounting, running ActiveShield 2.0 (roughly 3 million thermal checks a day). The primary USB-C1 port carries up to 140W (28V/5A); secondary C2/C3 cap at 100W each, and the USB-A port at 22.5W — every combination sums to exactly 240W by design. Community-verified EPR emulator testing (KM003C) found the primary port is sensitive to cable resistance, sporadically dropping to a conservative 60W safety profile with certain cables instead of the expected 140W.

Power Delivery in
140W

Confirmed with

  • Notebook (generic)

    A MacBook Pro 16" M1 Max owner using this exact unit (A2342) documents the primary USB-C1 port sporadically negotiating only 60W instead of the expected 140W or 100W — EPR emulator testing traced it to cable-resistance sensitivity forcing a conservative safety profile.

    Confirmed — caveat
  • Steam Deck

    Sporadically negotiates only 60W on the port instead of full capacity (erratic behavior reported), but 60W is still well above the Deck's 45W requirement.
