Which Anker is which: 11 power banks, from the first page of Anker’s US power bank collection, read 6 November 2026. 2 Prime packs, 140W from one USB-C port: Prime 26K at 300W in total, Prime 20K at 220W in total. Cables built in: Laptop 25K with 2 cables and 165W; the 20K 87W pack with 1 cable and up to 65W to one device. 6 magnetic wireless packs: MagGo 2 Pro at 25W Qi2.2, MagGo Slim and Nano 5K at 15W, Zolo and 633 at 7.5W, and the 621. Watt-hours printed on 3 product pages: Prime 26K 99.75Wh, Laptop 25K 90Wh, Prime 20K 72.36Wh. The other eight pages give capacity in mAh only. Specs from Anker’s own US product pages.

Anker’s US store lists 11 single power banks on the first page of its power bank collection, from 5,000mAh to 26,250mAh, and six of them charge a phone wirelessly. Two Prime models give 140W from one USB-C port, and Anker prints a watt-hour figure on three product pages: 99.75Wh, 90Wh and 72.36Wh.

The names overlap, which is where the confusion starts. Nano is on both a magnetic 5K pack and a 10K pack with a retractable cable; MagGo is on two current packs and in the name of the older 621. The full product name, with its bracketed capacity and wattage, is what to match. Specs below are from Anker’s own US product pages and prices are what those pages showed on 6 November 2026.

Counting the rows: three packs over 100W in total, four with a built-in cable, six with magnetic wireless charging. Watt-hours appear on three of the 11 product pages. Four pages offered an auto-applied discount code on 6 November (the Prime 26K, Prime 20K, Zolo and 621); for those, the table gives the price before the code.

Prime: the two 140W packs

The Prime Power Bank (26K, 300W) (affiliate link to Amazon, opens in a new tab) and Prime Power Bank (20K, 220W) (affiliate link to Amazon, opens in a new tab) share the same port layout, two USB-C and one USB-A, and the same 140W ceiling from a single USB-C port, which Anker reaches at 28V and 5A. Both pages list control from Anker’s app.

What separates them is capacity, total output and recharge speed. The 26K holds 26,250mAh against 20,100mAh, outputs 300W in total against 220W, and Anker rates it for 250W of recharging across two ports, against 100W for the 20K. The 26K weighs 600 g on Anker’s spec sheet; the 20K, 510 g.

That 140W figure is at 28V and 5A. A USB-C cable with the 60W logo is rated for 20V at 3A, below both numbers; what the logo on a USB-C cable tells you covers which marking goes higher.

Laptop Power Bank and the 87W pack: cables built in

The Laptop Power Bank (25K, 165W) (affiliate link to Amazon, opens in a new tab) carries two built-in USB-C cables, which its full name calls built-in and retractable, plus a USB-C port and a USB-A output. Anker gives each USB-C cable or port 100W and the pack 165W in total, from 25,000mAh, which its page states as 90Wh.

The Power Bank (20K, 87W, Built-In USB-C Cable) (affiliate link to Amazon, opens in a new tab) splits 87W across three devices, with up to 65W to one. Its page has no specification table: it gives 20,000mAh, the built-in cable, a full recharge in 1.5 hours from a 65W charger by Anker’s figure, and an 18-month warranty, and calls it “approved for airline travel”, without a watt-hour figure.

The magnetic packs: six ways to snap one on

Six of the 11 attach magnetically to the back of an iPhone and charge it without a cable. Wireless speed is the clearest split: 25W on one, 15W on two, 7.5W on two, and a figure not given on the sixth.

How fast a phone actually fills is up to the phone as much as the pack: a power bank’s rating is a ceiling, for the same reason a 65W charger does not charge a phone at 65W.

Nano 10K: a cable that pulls out

The Nano Power Bank (10K, 45W, Built-In Retractable USB-C Cable) (affiliate link to Amazon, opens in a new tab) has no wireless charging. It has a retractable USB-C cable, a USB-C port and a USB-A port, 45W from USB-C and a 30W recharge. Anker’s spec sheet caps the output at 22.5W in total once the cable and a port are used together.

Watt-hours: the figure that matters for flying

Airlines set power bank limits in watt-hours, and the US limits for flying with a power bank explains them and how to convert from mAh. Anker’s three stated figures are worth taking as printed rather than converting: divide each by its mAh and the voltage Anker used comes out at 3.8V for the Prime 26K and 3.6V for the Laptop 25K and Prime 20K. That is our arithmetic on Anker’s own two numbers, and it means a fixed 3.7V conversion gives a slightly different answer for each pack.

For the eight packs whose pages show no watt-hour figure, the label on the pack is the place to look. Anker calls the Prime 26K, Prime 20K and Nano 10K flight-approved on their pages, and the 87W pack “approved for airline travel”.

Who each one suits, by the specs

  • A laptop that charges over USB-C at more than 100W: the Prime 26K or Prime 20K, at 140W from one port.
  • A laptop plus a phone without carrying cables: the Laptop Power Bank, with two built in.
  • An iPhone, wirelessly and at the highest stated speed: the MagGo 2 Pro.
  • An iPhone, wirelessly, in a pocket: the Nano 5K at 0.34 inches, or the MagGo Slim for twice the capacity.
  • One cable for everything, no wireless: the Nano 10K or the 87W pack.

Questions people ask

What is the difference between Anker Prime 26K and Prime 20K?

Both give 140W from one USB-C port and have two USB-C ports and one USB-A. The 26K holds 26,250mAh (99.75Wh) and outputs 300W in total; the 20K holds 20,100mAh (72.36Wh) and outputs 220W. Anker rates the 26K’s recharge at up to 250W across two ports, the 20K’s at 100W.

Which Anker power banks charge wirelessly?

Six of the 11 we read: the MagGo 2 Pro at up to 25W, the MagGo Power Bank (10K, Slim) and Nano Power Bank (5K, MagGo, Slim) at 15W, the Zolo Magnetic and 633 at 7.5W, and the 621, whose page gives no wireless wattage.

What is the difference between Anker MagGo 2 Pro and MagGo Slim?

Both hold 10,000mAh and snap on magnetically. The MagGo 2 Pro is Qi2.2 at up to 25W, has a fan, a display, a fold-out stand and 45W USB-C. The MagGo Slim is 15W wireless with a 30W USB-C port and a 0.58-inch body.

Can an Anker power bank charge a laptop?

Anker gives the two Prime packs 140W from one USB-C port and the Laptop Power Bank 100W per USB-C cable or port. The 20K 87W pack gives up to 65W to one device; Anker says it takes a 14-inch MacBook Pro to 50% in under 40 minutes.

How many watt-hours is a 10,000mAh Anker power bank?

Anker’s product pages for its 10K packs do not print a watt-hour figure. It does on three larger ones: 99.75Wh for the Prime 26K, 90Wh for the Laptop 25K and 72.36Wh for the Prime 20K. For a pack without one on the page, check the label on the pack.

Is the Anker Prime 26K allowed on a plane?

Anker states 99.75Wh and calls the capacity TSA-approved. Airline limits are written in watt-hours, so that figure, not the 26K in the name, is the one to compare with your airline’s rules.

How we researched this

No one at bitcritiq has handled this product. Everything here comes from published sources, listed below.

What this cannot tell you
These are Anker’s own specs; we have not used any of these power banks, and this page does not rank them. The collection reported 38 items, including bundles; a “View More” control did not load further tiles in our browser, so models beyond the first 24 tiles are not counted. The Power Bank (20K, 87W) page has no specification table, so its ports and input are not stated here beyond what its feature text says. The MagGo 2 Pro page gives a comparison table instead of a specification list, and the 621 page lists no wireless wattage. The MagGo Power Bank (10K, Slim) showed one price with no higher price beside it, and the collection tagged it as on sale; we could not see a regular price. Prices and codes change often.
How we chose this, and what we did
Why this subject
Anker sells power banks under several names at once (Prime, Nano, MagGo, Zolo, Laptop Power Bank, and older three-digit models such as the 633 and 621), and the names describe different things: Nano appears on both a magnetic 5K pack and a cabled 10K one. We had covered the flight limits for power banks but not which Anker is which. Part of our lineup series; chosen as a carried pipeline candidate ahead of holiday travel, not on measured search demand.
How we looked at it
Read through a browser on 6 November 2026: Anker’s US power bank collection (anker.com/collections/power-banks, sorted Recommended) and Anker’s US product page for each of the 11 models, taking capacity, watt-hours, output, ports, wireless charging and price from each page’s price block, specification section and key features. The count of 11 is the single power banks among the first 24 tiles of that collection: we left out bundles and multi-packs, the Prime Charging Base (a dock, not a battery) and the Prime Power Bank (27K, 250W), which was marked sold out. Watt-hours are marked only where the page states them; the control for the “not listed” rows is that the same text search found watt-hour figures on the Prime 26K, Prime 20K and Laptop 25K pages. Prices are the price shown on each product page on 6 November; where the page offered an auto-applied code, the table gives the price before the code. The implied voltages in the watt-hours section are our arithmetic on Anker’s own two figures.
