Anker ·25,000 mAh
A 25,000 mAh power bank rated at 90Wh with 165W total output, three USB-C ports, and two built-in cables so a separate cable is not required.
Best for Travellers who would rather not pack a separate charging cable
Read the verdictResearch-based assessmentOfficial specifications and documented evidence. Not hands-on tested. Research score only. Not a Travistello Pick.
The short answer
The most practical travel option in this shortlist rather than the most powerful one. Two built-in cables remove the accessory most people forget, the 90Wh rating leaves real margin under the cabin limit, and the price sits well below the Prime. It gives up single-port output and app control to get there.
Travistello research score
Research-based, using Travel Power Bank Research Model v1.0. No physical test is implied.
165W documented total output is higher than the UGREEN, and the 100W input is faster, but 100W from a single USB-C port is materially below the 140W the other batteries here document. Sustained delivery is not independently measured.
30% of overall scoreAnker publishes 25,000mAh, 3.6V / 90Wh for this model and describes it as flight-approved. A published 90Wh rating leaves a real margin under the 100Wh threshold most carriers apply. Travistello has not verified acceptance for any specific airline, airport, or route.
25% of overall score90Wh at 595 g is roughly 151Wh per kilogram, the least energy per kilogram among the options here that publish a rating. The built-in cables account for part of that weight and remove a separate item from the bag, which is the trade this pack is built around.
20% of overall scoreThree USB-C ports, one USB-A port, a status display, a retractable USB-C cable, and a lanyard cable make this the most self-contained option in the set. No app connectivity is documented.
15% of overall scoreThe observed $119.99 official price sits well below the Prime for the same published 90Wh, with a documented 18-month warranty. The UGREEN snapshot is still cheaper for equivalent rated energy.

Evidence & methodology
A 0 to 10 research model for travel power banks. Flight readiness (25%), charging performance (30%), capacity to packed weight (20%), ports and usability (15%), and value and ownership (10%) are scored from time-stamped official specifications. Scores do not claim independent charging efficiency, sustained-output, thermal, or cycle-life testing.
