TL;DR: unifi Technician GPON ONU New Replacement Power Adapter was Different Model and Same Voltage with Different Lower Amperage
Yesterday after Power Outage and Back On, unifi FiberHome GPON ONU AN5506-04-BG 12V = 1.5A AN5506-04-B5G(E1) since 2017 December couldnt power back on at all, every other electrical appliance was still working well, try to contact TM via few method, 100 was the fastest to respond and record the detail, unifi easyfix could only report issue without record the detail, on-site appointment schedule was next day before 24 hour, unifi Technician arrive at schedule time, they didnt get the report detail, explain to them again, they just get a New Replacement Power Adapter from their vehicle and the unifi FiberHome GPON ONU work again without any issue including full correct speedtest with correct ping latency, however their New Replacement Power Adapter was Different Model and Same Voltage with Different Lower Amperage, is there any issues in the long run? thx in adv.

Lazimnya if it came with 1.5A PSU, better get back 1.5A or higher.
The manual says Power Consumption is <9W, so 12V 1A PSU is sufficient. No idea why it originally came with 12V 1.5A. Maybe 1A no stock or different hardware using more power.
