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). (1 sourced review, 1 lab-tested.)
Praised: Charges a 100W ultrabook as expected, with charging curves comparable to similar-spec rivals; Distinctive see-through design plus IPS info screen; more travel-friendly than the metallic Chargeasap Flash Pro; USB-A port reliably handles anything thrown at it.
Flagged: Clear polycarbonate shell developed faint milky discoloration streaks early in testing; Charged a Galaxy S22 Ultra only ~35W (below its 45W rate) and cannot fully fill a laptop to 100%; On-screen temperature and charging readouts did not match FLIR imaging or a USB multimeter.
