What is it?
A 20,100mAh (72.36Wh) power bank, model A110B, with two USB-C ports, one USB-A port and a display. Anker lists up to 140W from one USB-C port and 220W combined. This listing does not include the charging base.
Who is it for?
Someone whose outage plan includes a laptop that charges over USB-C, or several devices at once. For phones only, Popular Science calls it unnecessary weight and money.
How is it used?
Recharge it before the outage with a charger of at least 100W and a 5A cable for its fastest input. Then connect the laptop to a USB-C port. Anker supports charging the bank and a device at the same time.
Every outage plan starts with the phones. Then somebody remembers the work laptop, the one with the deadline on it, and the phone bank on the counter suddenly looks small.
What it does when the power is out
The Anker Prime Power Bank 20K 220W is the bank for that laptop. Anker lists up to 140W from one USB-C port and 220W combined across two USB-C ports and one USB-A port. One owner saw about 140W going into a MacBook Pro, and says charging a phone and earbuds at the same time also worked fine.
It does not hold more than a phone bank. Anker lists 20,100mAh, or 72.36Wh, about what the 87W A1383 holds. What you pay for is how fast it can push that energy out. Popular Science says it plainly: if you only need to charge a phone, it is unnecessary weight and money.
Plan the recharge before the storm
For its fastest input, 100W over USB-C, Anker asks for a charger of at least 100W and a 5A cable. The US box has a 240W USB-C cable and a pouch, but no wall charger and no charging base. Fstoppers got a full recharge in about 45 to 50 minutes. Anker also supports charging the bank and a device at the same time. If it sits in the cupboard between outages, Anker’s quick start guide asks for a charge at least once every three months, so put that date on the calendar next to the smoke alarm check.
Heat, an app and a laptop battery
SmartZone measured 90 to 93 percent of the rated energy as usable, and also found that it throttles hard and runs hot above 140W. There is no built-in cable, which 9to5Mac missed. The display and the app settings are a matter of taste: one commenter says the best thing for charging speed is to set it to AI mode and leave it alone, and a commenter is baffled that a power bank needs firmware updates at all.
Popular Science adds that this is a 72Wh pack, not a full replacement for a laptop battery. Count on topping up the laptop for the one job that cannot wait.
Straight from the threads
"Tested it with my MacBook pro and it hit around 140W. Charging my phone and noise-canceling earbuds at the same time also works totally fine."Owner on r/UsbCHardware, December 2025
"I use iPhone 13 Pro Max and an older 10” iPad. If they are both around 10-20% battery i can charge both full with this battery bank."Owner on r/anker
"Honestly, for maximum charging speed, the best thing you can do is put it in AI mode and leave it alone."Commenter on r/UsbCHardware
"I'm baffled why something as trivial as a powerbank needs an App and firmware updates:-("Commenter on r/anker
The first owner names the bank by output and capacity (Anker 220W, 20K), not by the A110B number; the box in his photo reads Anker Prime Power Bank (20K, 220W).
Main limitation
It stores about the same energy as the 87W A1383 in our guide; the extra is output, not capacity. SmartZone found it throttles hard and runs hot above 140W.
Who should pick something else
- Your outage list is phones and a light: the Anker 87W power bank holds about the same energy and keeps its cable built in.
- You expect several days without power: compare stored energy in the emergency power bank guide.
Compare both Ankers
Capacity, ports and recharging sit side by side in the emergency power bank comparison. The laptop with the deadline gets the 140W port. The phones can wait their turn.
These photos come from a used eBay listing of the Anker Prime A110B and from an owner on Reddit who posted it right after unboxing. Neither shows the charging base, which this listing does not include.
Questions before you choose.
Does 220W mean more stored energy?
No. Watts are power, not stored energy. Anker lists 20,100mAh and 72.36Wh, about what the 87W A1383 holds.
Is the charging base included?
No. This listing is the A110B without the charging base; the base is sold separately. The older 200W Prime (A1336) is a different model.
Will it run a laptop through a long outage?
Popular Science calls it a 20K-class pack of about 72Wh, not a full replacement for a laptop battery. Plan on top-ups, not a full workday.
Who sells it on Amazon?
On October 22, 2026 the Amazon offer was sold by AnkerDirect, not by Amazon. Check the seller on the page before you buy.
