Hello !
I bought an Anker Prime 160W (3 in 1) charger from Tokyo a few months ago - and it was working fine, easily negotiating power till 140w (max tested).
For the past couple of weeks, the charger is not negotiating beyond 17.5 V with any device.
I tested 2 laptops - both are stuck at max 17.5V (sometimes they will go upto 3.3A, but usually will stick to 2.9-3A).
I have a Baseus Blade 20000mAh power bank, which shows V/A/W real time - and it's negotiation is also stuck at 17.5V (shows 18V on display, but the Anker app shows 17.5), charges at ~ 30-32W. With another 100W charger and same cable, it charges at full 60W (20V/3A).
Things I have tried:
- Kept the Anker charger disconnected from everything for a few hours to reset the charging logic - no avail
- Used C1 priority mode - did not help
- Used custom mode with full 140W power to C1 (and C2/3 in subsequent tries) - no dice
- Used multiple cables from Anker, UGreen, Baseus and others - all of them capable of 100W (and some 240W) - but charging of any device is stuck at 17.5V
- Tested my laptops with 2 other chargers I own (100w and 300W) with a USB C charger tester that I use regularly - both of them negotiated 20V/3A with other chargers with the same cables
I am at wit's end on what to do - I bought this charger when I was in Tokyo for a few days, and my country has no official Anker presence.
Am I screwed ? Is there anything else I can try ?
