Detailed overview: Anker A1383 20,000 mAh 87 W built-in cable power bank
The Anker Power Bank 20,000 mAh 87 W, reference A1383, belongs to that new generation of power banks carrying their own cable. The USB-C cord sits in the casing, held in a groove, and deploys in one motion: no need to carry a separate cable, or to realise at the station that you forgot it. Anker rates it for over 10,000 bends, a credible figure given the quality of the braid and the reinforcement at the connector.
The 20,000 mAh capacity, around 72 Wh, places this pack at the top end of models still allowed in the cabin (the usual limit being 100 Wh). In practice it recharges a recent smartphone about four times, a tablet once or twice, or tops up an ultraportable through a working day.
On power, the A1383 delivers up to 87 W in total. The built-in USB-C cable and the USB-C port each reach 65 W, enough to feed a MacBook Air, a Dell XPS 13 or a Nintendo Switch at fast-charge speed. The USB-A port rounds things off with 22 W. Three devices can therefore be powered at once, with the pack intelligently splitting the available output between them.
Recharging the pack itself is a strong point: with a 65 W USB-C charger it goes from 0 to 100% in about an hour and a half, where many models of this capacity ask for three to five hours. A small display shows the remaining charge as a percentage, more precise than the traditional four LEDs. At 465 g it remains a bag power bank rather than a pocket one, but that is the price for this combination of capacity, power and convenience.

Comparison
Around 70 euros, the Anker A1383 compares to the 20,000 mAh fast-charging packs sought for travel and nomadic work, via searches like "20000 mAh power bank laptop" or "power bank built-in cable". Here is how it stands against three alternatives: the Anker Prime 20000 200W, the Ugreen Nexode 145W and the Anker Zolo 20000.
| Criterion | Anker A1383 87W | Anker Prime 20000 200W | Ugreen Nexode 145W | Anker Zolo 20000 |
|---|---|---|---|---|
| Capacity | 20,000 mAh | 20,000 mAh | 20,000 mAh | 20,000 mAh |
| Total power | 87 W | 200 W | 145 W | 22.5 W |
| Built-in cable | Yes (USB-C) | No | No | Yes (USB-C) |
| 0-100% recharge | ≈ 1.5 h | ≈ 1 h | ≈ 1.5 h | ≈ 5 h |
| Observed price | ≈ 70 € | ≈ 130 € | ≈ 100 € | ≈ 40 € |
In short, the A1383 occupies a very coherent spot: it offers the built-in cable and a useful 65 W for an ultraportable, without the price of 145 to 200 W models whose power exceeds what most users need. The Prime 20000 and the Ugreen Nexode target those charging a 16-inch MacBook Pro or several demanding machines; the cheaper Zolo 20000 stops at 22.5 W and suits phones above all. For a traveller wanting a single pack that does everything without carrying a cable, the A1383 is the best compromise of the group.

Our tester's review: Guillaume Hoarau
We carried this Anker A1383 through a month of travel, and the built-in cable genuinely changes things. It sounds trivial, but no longer digging through a bag for a USB-C cord is the kind of detail you never give up once you have had it. The cable is short but well designed: it stows in a groove in the casing and doubles as a strap to grab the pack. On power, the 65 W available on that cable charged our MacBook Air through a meeting without the machine complaining, and an iPhone 16 went from 20 to 80% in a little under half an hour. The 20,000 mAh easily cover two days of heavy phone use, or a full day juggling phone, earbuds and tablet across the three outputs. The small display shows the remaining percentage, which avoids nasty surprises at the airport. Two honest caveats: at 465 g you feel it in a jacket pocket, and the 1.5-hour full recharge assumes you have a 65 W charger to hand, otherwise expect far longer. For travel or nomadic work, it is an excellent companion.
