Overview

Anker's Prime 100W charger offers two USB-C ports and one USB-A port. The top USB-C port is rated for up to 100W on its own, which covers laptops that charge at around 90–100W over USB-C.

Anker states 100W combined with two ports in use and 89W with all three, but doesn't publish how the total is divided. It recommends the upper port for a laptop when both USB-C ports are in use.

Best for: A 100W laptop, with room for a phone.

Device suitability

  • Laptop: light (~30W)Likely fit
    up to 100W available from a single port (you need ~30W).
  • Laptop: standard (~65W)Likely fit
    up to 100W available from a single port (you need ~65W).
  • Laptop: performance (~100W)Likely fit
    up to 100W available from a single port (you need ~100W).
  • Laptop: maximum (~140W)Works, but slower
    the strongest suitable port is rated 100W, below the ~140W you selected. It should still charge, just more slowly.
  • Phone: typical (~20W)Likely fit
    up to 100W 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 100W available from a single port (you need ~20W).
  • Tablet: fast (~35W)Likely fit
    up to 100W available from a single port (you need ~35W).
  • Smartwatch: typical (~5W)Likely fit
    up to 100W available from a single port (you need ~5W).

Editor's notes

  • Laptops up to ~100W: use the top USB-C port.
  • Laptop plus phone: 100W combined with two ports, but the exact split isn't published.
  • Three devices: 89W combined across all ports.

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 ties the 100W single-port figure to the top USB-C port (C1). Wording elsewhere suggests C2 may also reach 100W, but it is ambiguous, so we list C2 as not published.
  • Neither USB Power Delivery nor PPS is named on the pages we checked.
  • 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 found for this model (checked 2026-10-24 via saferproducts.gov).
