100W GaN USB-C Wall Charger, 3-Port
Anker and Belkin charge $70-90 for 100W 3-port GaN; at $54 with per-unit load testing and a 36-month warranty (theirs are 18-24), you get equal silicon and stricter QC for 25-40% less — we spend on testing rigs instead of Super Bowl ads.

Braided 240W USB-C Cable, 2m
Certified 240W braided cables from the big accessory brands run $25-35; at $19 this carries the same USB-IF certification and a longer flex-test spec, future-proof for EPR laptops — the only thing missing versus the $35 cable is the logo.

65W GaN Travel Charger with Folding Plug
Comparable 65W dual-port GaN travel chargers run $45-60 retail; at $36 with per-unit load testing, a cycle-tested folding plug, and a 36-month warranty, this is 20-40% under the brands for a strictly tighter QC regime.

10,000mAh USB-C Power Bank, 30W PD
Anker-class 10K/30W banks run $55-75; at $44 you get tier-1 matched cells and a metal thermal-mass shell — the two determinants of how long a bank actually lasts — plus a 24-month warranty, at 20-40% under equivalent name-brand units.

Surge-Protected Desktop Power Station
Comparable desk stations with 65W PD run $95-130 and almost none have replaceable suppression; at $74 this pairs a 65W GaN port with serviceable surge modules — the only station you keep after the MOVs do their job — at 20-40% under the category.

8-in-1 USB-C Hub with 4K60 HDMI
Comparable 8-in-1 hubs with true 4K60 (not 4K30) and UHS-II card slots run $90-130 from Anker, Satechi, and CalDigit's lower tier; at $69 with per-unit jig testing and an anchored pigtail this is 25-45% less for the same port silicon.

MagSafe-Compatible 15W Charging Stand
Belkin and Mophie Qi2 stands run $60-90; at $48 this delivers certified full-speed 15W MPP charging with a heavier, more stable base than either — the base is where they cheap out — for 20-45% less, warranted for 3 years.

USB-C to HDMI 2.1 Cable, 8K, 2m
Cable Matters and Belkin charge $40-55 for HDMI 2.1 conversion cables; at $29 with 100% per-unit signal testing — the category's defect rates make this the feature that matters — you save 25-45% and skip the return-lottery entirely.
