Overview

Anker describes this as a 250W charging station for the desk. It runs on an AC cord and offers four USB-C ports and two USB-A ports. The first USB-C port is rated up to 140W, the other three up to 100W each, and the USB-A ports up to 22.5W.

Anker states up to 240W with two ports in use and up to 250W with three to six, but doesn't publish the per-port split. A 2.26-inch screen and a control dial show readings and set the power-sharing mode.

Best for: A 140W laptop plus several more devices on the desk.

Independent tests

  • ChargerLAB: Teardown of ANKER Prime 250W GaN Charger (A2345), published . Our reading: found no faults, but didn’t test the power claims.
    Opened the A2345, photographed and identified its internal parts, and read each port's charging protocols with a USB tester. It reported no faults; it didn't publish load or temperature measurements.

Device suitability

  • Laptop: light (~30W)Likely fit
    up to 140W available from a single port (you need ~30W).
  • Laptop: standard (~65W)Likely fit
    up to 140W available from a single port (you need ~65W).
  • Laptop: performance (~100W)Likely fit
    up to 140W available from a single port (you need ~100W).
  • Laptop: maximum (~140W)Likely fit
    up to 140W available from a single port (you need ~140W).
  • Phone: typical (~20W)Likely fit
    up to 140W available from a single port (you need ~20W).
  • Phone: fast (pps) (~45W)Needs verification
    power is sufficient, but we couldn't verify PPS support, so we can't confirm its fastest charging.
  • Tablet: typical (~20W)Likely fit
    up to 140W available from a single port (you need ~20W).
  • Tablet: fast (~35W)Likely fit
    up to 140W available from a single port (you need ~35W).
  • Smartwatch: typical (~5W)Likely fit

Editor's notes

  • Laptops up to ~140W: use the first USB-C port (C1).
  • Laptops up to ~100W: any of the other USB-C ports.
  • Two devices: up to 240W combined; three to six: up to 250W, but the split isn't published.

Based on published specifications and typical power needs for each device type, one device at a time. It isn't a guarantee for a specific model, so check your device's own charging specs.

Evidence notes

  • Anker's page calls it an “Ultra-Powerful 250W Charging Station” and recommends “using the provided AC cord or a standard C7 2-pin AC cord”. No separate power adapter is listed.
  • Anker lists six USB ports (four USB-C, two USB-A) and no AC outlets.
  • Anker doesn't state the AC cord's length. ChargerLAB's teardown measures it at about 1.5 m, but that isn't a manufacturer figure, so we don't record a length.
  • Multi-port totals by number of ports in use: “Two Ports in Use: Up to 240.0W Max.”, and “Up to 250.0W Max” for three, four, five and six ports. Per-port splits aren't published, so no allocation table is recorded.
  • Anker notes that “OTA upgrades or different firmware versions may result in optimizations and variations in power distribution.”
  • Anker's USB-C1 voltage list starts at 9V (9V, 15V, 20V, 28V); we record it as published. USB-C2 to C4 are listed at 9V, 15V and 20V (100W max).
  • Anker lists voltage steps without naming USB Power Delivery or PPS, so both are marked unverified.
  • Release month not recorded: Anker's product page gives no date for this model, and we found no Anker press release naming it. The download date on its quick start guide isn't an availability date.
  • The page doesn't state how ChargerLAB obtained the unit.
  • We couldn't check the UL and Intertek certification databases automatically on 2026-10-24; a manual check is still to do.
  • No FCC ID is stated on Anker's pages we read.
  • No CPSC recall names this charger; Anker's recalls (2021–2025) cover power banks, speakers, coolers and children's products (saferproducts.gov and Anker's product recalls page checked 2026-10-24).
