Overview

Anker's 8-in-1 station is a compact power strip for the desk: two AC outlets, four USB-C ports each rated up to 140W on its own, and two USB-A ports at 5V/2.4A.

The USB ports share 240W with two to four in use and 237W with five or six; Anker doesn't publish the per-port split. It connects to the outlet through a separate wall adapter on a 5 ft cord, and Anker states 300J surge protection.

Best for: Laptops, phones and two mains plugs from one desk strip.

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
    up to 140W available from a single port (you need ~5W).

Editor's notes

  • Laptops up to ~140W: any USB-C port.
  • Two to four USB devices: 240W combined, but the split isn't published.
  • Lamps, monitors or other mains plugs: two AC outlets.

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 names it a “Charging Station” and “The Ultra-Fast 8-Port Compact Power Strip”, with “2 AC outlets, 4 USB-C, and 2 USB-A ports”.
  • Anker lists a separate “Wall Adapter” (21.32 oz) alongside the station (8.11 oz), and the user guide warns against suspending the “DC module in the output line”, so we record an external power supply. The guide also refers to a “built-in USB module” that supports 100–240V input.
  • Anker: “The length of the power cord is 5 ft (including the plug).” Converted to 1.52 m. Anker doesn't say which part of the cord the 5 ft covers relative to the wall adapter.
  • Weight not recorded as one figure: Anker gives 8.11 oz for the station only and 21.32 oz for the wall adapter.
  • Dimensions are converted from Anker's 3.07 × 5.43 × 0.71 in (station only); with the wall adapter, Anker lists 4.06 × 3.07 × 1.25 in.
  • Input voltage not recorded: the product page lists “100-240V 50-60Hz”, while the user guide lists AC input as 125V~ 60Hz, 13A for the outlets and notes the USB module supports 100–240V.
  • Multi-port totals by number of USB ports in use: “2 Port Output 240W Max”, the same for 3 and 4 ports, and “237W Max” for 5 and 6 ports. Per-port splits aren't published, so no allocation table is recorded.
  • USB-A output is stated as 5V⎓2.4A (12W) per port.
  • Anker lists USB-C voltage steps without naming USB Power Delivery, PPS or GaN for this model, so they are marked unverified.
  • Anker lists certification marks (cTUVus, UL standards, “FCC - sdoc(US)”) on the product page; these are maker statements, not certification records, and no FCC ID is stated on Anker's pages we read.
  • 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.
  • No independent review with shown measurements of the A91B2 was found.
  • We couldn't check the UL and Intertek certification databases automatically on 2026-10-24; a manual check is still to do.
  • No CPSC recall names this charging station; 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).
