Detailed overview: Anker Prime 20,100mAh 220W power bank
The Anker Prime 20100 (220W) succeeds the 200W generation with a clear power jump: its two USB-C ports now reach 140W each (up from 100W on the previous model), and total output climbs to 220W with the USB-A port included. That's enough to charge a MacBook Pro M4 from 0 to 50% in just 28 minutes, or a 13-inch iPad Pro (M4) in 48 minutes.
Its 20,100mAh capacity, or 72.36Wh, stays under the 100Wh cabin baggage limit set by airlines, so it travels without restriction and can charge an iPhone 16 Pro up to 3.6 times. Recharging the battery itself benefits from the same power boost, with up to 100W USB-C input to recover 50% of its capacity in 31 minutes.
The smart display, which rotates automatically depending on the battery's orientation, shows the remaining percentage, the power delivered on each port and the estimated charging time in real time. Paired with the Bluetooth-connected Anker app (PowerIQ 4.0 technology), it lets you track exactly how energy is distributed across the three ports and customise the screensaver. The ActiveShield 4.0 system monitors temperature continuously to keep every connected device charging safely.
Another strength is two-way charging, which allows the same USB-C ports to handle both input and output as needed. The box includes a certified 240W USB-C to USB-C cable (1 metre) plus a travel pouch, so there's nothing extra to buy. The one downside noted by several users: at 510 grams, it's a dense unit, better suited to a work bag or travel case than a jacket pocket.
With 626 reviews and a 4.6/5 rating on Amazon, the Anker Prime 20100 220W is aimed at mobile professionals who regularly charge a laptop, a phone and a tablet on the road, without wanting to invest in the pricier, bulkier 26,250mAh model.

Comparison
At around £90, the Anker Prime 20100 (220W) competes with fast power banks aimed at searches like "140W MacBook power bank" or "flight-approved fast charging power bank". Here's how it compares to three alternatives: the previous-generation Anker Prime 20000 (200W), the Ugreen Nexode 20000 145W, and the bigger Anker Prime 26250 (300W).
| Criterion | Anker Prime 20100 220W | Anker Prime 20000 200W | Ugreen Nexode 20000 145W | Anker Prime 26250 300W |
|---|---|---|---|---|

| Display + Bluetooth app | Yes | Display only | Display only | Yes |
| Price observed | ≈ £90 | ≈ £100 | ≈ £85 | ≈ £160 |
In short, the Anker Prime 20100 sits at the sweet spot of the range: it delivers the real power jump of the 220W generation (140W per port, versus 100W on the older model and the Ugreen), while staying notably more affordable than the Prime 26250 300W and its 250W input reserved for the most demanding use cases. For anyone charging a laptop daily without needing 300W, it's the best balance of capacity, power and price in the Anker Prime range.

Our tester's review: Guillaume Hoarau
We carried the Anker Prime 20100 on business trips for several weeks, between trains and impromptu work sessions in coffee shops. The 140W USB-C port lives up to its claims: our MacBook Pro M4 went from 20% to 70% during a single lunch break, no wall charger needed. The display, which rotates automatically depending on how the battery is held, stays readable even in bright sunlight, and knowing exactly how many watts go to each port avoids nasty surprises. The Bluetooth-connected Anker app adds real convenience for tracking the charge remotely. The one real gripe: at 510 grams, it clearly belongs in a bag rather than a pocket, and the price sits above a generic power bank. For phone-only use, it is overkill. But for anyone regularly charging a laptop on client visits, it is a dependable choice, charge after charge.
