What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
UGREEN Nexode Power Bank 25,000mAh 145W (PB553)
Two whitelisted outlets hands-on tested a UGREEN 25,000mAh 145W power bank and both recommend it. TechRadar's bench measured 76-88% of rated capacity delivered across loads (85% at 20W, 88% at 30W, 82% at sustained 100W, 76% at 140W) and praised the compact 505 g build as smaller and lighter than similar-capacity rivals. Engadget clocked a fast iPhone 15 refill (about an hour and a half from 4% to full) and confirmed the digital charge display reads accurately. Downsides: TechRadar found it runs hot and throttles at sustained 100W+ and self-recharges at only 65W; Engadget flagged weak value at the $120 launch price and intermittent stock. Note: TechRadar lists the unit's model as PB205 rather than the title's PB553, but capacity, total 145W and 140W single-port specs match exactly. (2 sourced reviews, 2 lab-tested.)
Praised: Fast charging — strong measured efficiency across loads plus quick real-world phone refills from the 145W / 140W single-port output; Compact and relatively light for a 25,000mAh (90Wh) capacity; Accurate digital charge-percentage display.
Flagged: Runs hot at sustained 100W+ output and can throttle back its wattage; Self-recharge input limited to 65W; Weak value at the $120 launch price and intermittent stock availability.
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.
