Comparison
At around £111 to £154, the EcoFlow Rapid Pro 27K compares with high-end power banks of roughly 25,000 to 27,000 mAh, targeted by searches such as "laptop power bank" or "140W power bank". Here is how it sits against three references: the Anker Prime 27,650 mAh, the Ugreen Nexode 145W 25,000 mAh and its bigger sister the Rapid Pro X.
| Criterion | EcoFlow Rapid Pro 27K | Anker Prime 27,650 | Ugreen Nexode 145W 25000 | EcoFlow Rapid Pro X |
|---|---|---|---|---|
| Capacity | 27,650 mAh | 27,650 mAh | 25,000 mAh | 27,650 mAh |
| Total output | 300W | 250W | 145W | 300W |
| Built-in cable | Yes (USB-C 140W) | No | No | Yes |
| Screen | Yes | Yes | No | Yes |
| Observed price | ≈ £119 | ≈ £137 | ≈ £77 | ≈ £204 |
In short, the Rapid Pro 27K stands out for its 300W output, the highest of the group, and its built-in 140W USB-C cable that avoids carrying accessories. The Anker Prime is its closest rival (identical capacity, 250W), the Ugreen 145W is far more affordable but less powerful and without a screen. The Rapid Pro X offers the same performance with an even more premium finish, but clearly pricier. For a powerful all-in-one travel bank, the Rapid Pro 27K is excellent value.

Our tester's review: Guillaume Hoarau
The Rapid Pro 27K has become our go-to travel bank, and it owes that mainly to its built-in 140W USB-C cable: no more digging through the bag, you pull out the 60 cm cable and charge, laptop included. The 300W output across four ports lets you plug in a MacBook, a phone and a tablet at the same time without slowing down, real convenience on the move. Its 27,650 mAh (99.54 Wh) stays under the aircraft cabin limit, making it an ideal flight companion, and the LCD screen gives the remaining percentage at a glance, no guessing. Recharged on the Rapid Pro 320W station, it reaches 80% in about twenty minutes, spectacular. The interchangeable magnetic cases are a fun touch to personalise the look. Two honest caveats: at full power it warms up and drains fast (300W is huge for a power bank), and the price sits above classic power banks. But for anyone wanting a single battery able to recharge everything, laptop included, it is an excellent choice.
