ASOMETECH's charger advertises GaN semiconductors and a 140W total output across multiple USB-C/USB ports with QC4.0 and PD support; that combination suggests very-fast multi-device charging and compact GaN efficiency, but available buyer feedback is minimal (31 units sold) so reliability and real-world multi-port power distribution remain uncertain.
Buy if you need a compact, high‑power GaN charger for laptops and phones; avoid if you require proven long‑term reliability or detailed certification info.
