Detailed overview: Aukey PB-Y63 27600mAh 140W power bank
The Aukey PB-Y63 Spark Sling is a very high-capacity power bank, designed for heavy on-the-go needs. With its 27600mAh (about 99Wh) and an output of up to 140W via Power Delivery 3.1, it sits at the very top of the category: it does not just charge smartphones, it also powers demanding laptops, MacBook Pro included, at full speed.
It has a digital display showing in real time the power delivered and the remaining runtime, a real comfort for managing its use. Its 27600mAh capacity charges a smartphone many times, or gives a full charge back to a laptop. An important detail for travellers: it stays just under the 100Wh threshold, which makes it carry-on allowed by most airlines, where many banks of this capacity are forbidden.
On paper, it is one of the best very-high-capacity power banks, on a par with the Anker 737. But one major point must be flagged: the Aukey brand was banned from a major marketplace in 2021, in the same purge as RAVPower, for fraudulent customer-review practices. Since then, Aukey is sold only via its own European site (eu.aukey.com) and has disappeared from French marketplaces.
In practice, the product remains buyable directly from Aukey, but its availability and after-sales support are less obvious than with major brands still present in mainstream retail. For a very high-capacity power bank meant to charge a laptop, it is therefore advisable to compare it with alternatives like the Anker 737 (24000mAh, 140W) before choosing.

Our tester's review: Guillaume Hoarau
The Aukey PB-Y63 is one of the most ambitious power banks on the market: 27600mAh, one of the largest capacities you can take on a plane, and 140W output, enough to charge a MacBook Pro or a USB-C laptop at full speed. In use, it is a real backup powerhouse: several smartphone charges, a laptop topped up effortlessly, and a display that clearly shows the power and remaining runtime. Staying under 100Wh is a real plus for travellers. Technically, it rivals the Anker 737. The main downside concerns the brand: Aukey was banned from a major marketplace in 2021 for fraudulent reviews, and is now sold only on its own European site. Availability and after-sales support are therefore less obvious than with Anker or Ugreen, which calls for comparison before buying.
Frequently asked questions: Aukey PB-Y63 27600mAh 140W power bank
Yes, that is its main asset. With 140W output, it charges most USB-C laptops at full speed, including a MacBook Pro, on top of smartphones and tablets.
Yes. At about 99Wh (27600mAh), it stays just under the 100Wh cabin threshold allowed by most airlines, which is rare for such a high capacity.
The Aukey brand was banned from the Amazon platform in 2021 for fraudulent customer-review practices. Since then, it is sold only via its own European site and has disappeared from French marketplaces.
For a very high-capacity, powerful power bank, the Anker 737 (24000mAh, 140W) or the Ugreen 145W (25000mAh) are excellent alternatives, far easier to buy and to get warranty support for.
