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.

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.
