About
A 24,000mAh (>600g) prismatic power bank and one of the earliest mass-market units supporting bidirectional PD 3.1 EPR (28V/5A, 140W), managed by PowerIQ 3.0. The 140W ceiling is a hard total, not per-port — C1 and C2 cannot both hit 140W at once. Steam Deck OLED owners report a systemic handshake failure where the console rejects the PD 3.1 profile and drops to just 20W with warning lights, typically fixed by inserting a hub/dock as an intermediary; the ASUS ROG Ally, by contrast, reliably negotiates 30W Turbo mode and is recognized by Armory Crate as a valid 65W+ adapter.
