Where the facts come from

Our sources and standards

Every source behind the current catalog, and how we use each one.

How we check a product

Maker documentation is our main source for which model is which and what its specs are. Independent test publications help us check real-world performance and the limits that matter. We sum up their findings in our own words and never pass off another publication’s testing as ours.

Customer reviews can point to common frustrations. We treat them as a reason to dig deeper, never as a verified measurement.

Standards, safety and program rules

USB-IF Power Delivery voltage and cable overview

USB Implementers Forum, Program policy, checked October 2, 2026

Primary standards-body explanation of 100 W Power Delivery through 20 V and a 5 A USB-C cable. Applied to the EcoFlow manual’s 20 V and 100 W input ceiling. This is a connection requirement, not proof of a particular charger pairing or a sustained charging rate.

USB Type-C Cable and Connector Specification Release 2.0

USB Implementers Forum, Program policy, checked October 2, 2026

Printed pages 36 to 37 and 143 establish cable current limits and electronic marking for more than 3 A. Used for the 5 A cable requirement at the EcoFlow 100 W ceiling. This base specification does not imply that a current cable must carry a retired 100 W certification logo or that the station supports higher extended voltages.

US support FAQ and authorized Amazon sellers

Hurom, Program policy, checked September 22, 2026
