Summary

A 20,100mAh (72.36Wh) travel power bank that can run a laptop at 140W from a single USB-C port and refill itself at 100W in under an hour.

Strengths

  • Delivers 140W to a 16-inch MacBook Pro in real-world testing, with no slow-charger warnings.
  • The 100W input refills it in about 45-50 minutes, with 50% in roughly 25 minutes.
  • 220W total runs a laptop and a phone together without dropping into slow charge.
  • The smart display and app show live wattage and time-to-full.
  • At 72.36Wh it stays under the airline carry-on limit.

Weaknesses

  • One Reddit owner reports throttling under sustained power; two reviewers did not see it, so treat it as unconfirmed.
  • Warranty terms are inconsistent: 24 months on Anker’s EU and UK pages, 12 months on the US storefront.
  • The 72.36Wh headline is not what reaches your phone, because Anker says 30-45% is lost in conversion.
  • The charging base is sold separately and is not included.

Full research notes and sources

Output, recharge and heat

Popular Science tested it over several weeks and found the 140W single-port and 220W total figures show up in real use with no slow-charger warnings and no throttling. Fstoppers ran it for a month with a 16-inch MacBook Pro: 140W delivered with no throttling, laptop and phone together handled without drama, and a full recharge in about 45-50 minutes with 50% in roughly 25 minutes. It says 72.36Wh extends a 16-inch laptop by about 60% or charges an iPhone 17 Pro Max about 4 times, and the unit survived a 3-foot drop.

Heat is well controlled but present. Anker rates the safety system as ActiveShield 4.0 temperature monitoring, and recharging may pause when the cells are warm after heavy use.

What the numbers leave out

The 140W output requires a 5A cable, and Anker says a 100W-plus charger is needed to hit the 100W input. More importantly, Anker’s own FAQ states 30-45% of energy is lost in conversion, so a fully charged 20,100mAh bank delivers only about 11,250mAh to your devices. Simultaneous charge-and-discharge also reduces output to 70-80% of input power, and the display itself draws power and adds a little heat.

Warranty and app

Warranty coverage depends on where you buy. Anker’s EU and UK product pages list 24 months, the US storefront’s “what you get” lists 12 months, and a reseller spec sheet says 2 years, so confirm terms before relying on them. The app handles firmware updates (7-10 minutes, keep it open) and power-distribution settings over Bluetooth, and there is a reset procedure for Bluetooth pairing.

Is it worth it?

At $179.99 list it is expensive for the capacity class, and Anker has sold it with a $50 discount. Price bands help here: below about $130 it is a strong buy for laptop-class output in a carry-on-safe pack; $131-160 stays good value for frequent travellers; $161-180 is fair and only makes sense if you need exactly this combination of 72.36Wh, 140W single-port output and 100W input; above $180 it is weak value next to higher-capacity packs. A January 2026 hands-on saw a $149 sale price, and Fstoppers referenced $150. If 220W total is not needed, the Anker 737 (140W total) is $109.99. The optional charging base is extra at about $99-100, and a Newegg bundle with the base lists at $279.99.

Which model this is

This page covers the Anker Prime Power Bank (20K, 220W), model A110B. The A110G is the Black Myth: Wukong limited edition with identical published electrical specifications. Don’t merge it with the older 200W A1336, the Anker 737 (PowerCore 24K, 140W), or the 26K/300W model; those are different products.
