Title: Gemini shutting down PS Vita charger?
Post by: John Veness on September 17, 2018, 03:58:41 pm
Has anyone tried charging their Gemini with a PlayStation Vita charger, specifically the PCH-ZAC1, as pictured:

I've tried using this charger, with the USB A-to-C lead which came with the Gemini, on two occassions. Both times, the Gemini was charged up a few dozen percent OK, but then stopped charging before it was full (less than 50%) - the red light on the top of the case went out, and there was no charging symbol on screen. What's more, the charger itself seemed to stop working on other devices. However, after some hours or days, the charger started working again. As I say, this happened twice, exactly the same, including the charger coming back to life again later. I haven't tried since, in case it was causing some damage. The Vita charger seems fine for all my other devices, and other non-Gemini USB chargers seem to work OK on the Gemini.

So, as I say, I was wondering if anyone else has tried this charger, or wishes to do so if they're brave. I can't work out what would cause it to stop working for several hours like that. If it was a blown fuse, you would expect it to not start working again!

Sounds like a thermal cutout, did the charger get hot when connected to the Gemini?

I don´t know much about the smarts involved with USB charging, but just looking online at the specs for the PCH-ZAC1 and the details on your photo, 1.5A at 5V seems a bit light for charging the Gem.  I haven´t got mine yet, but I´ve read on here that the Gem charges 2A at 5V, up to 1.25A at 12V, which is a lot more power than the charger you´re trying can supply.
