## What reviewers say

**Shargeek Storm 2 Slim Power Bank 20,000mAh 130W** — Only one whitelisted tester (Notebookcheck) hands-on-reviewed this exact model; mainstream outlets like PCMag, Tom's Guide and Wirecutter never covered it. Notebookcheck found the Slim charged a 100W ultrabook as expected and praised the see-through design, but flagged early milky discoloration of the clear shell and sub-rated phone charging (~35W to an S22 Ultra).
