Original USB HUB and HDMI adapter for Gemini PDA are really expensive. Maybe it's interesting for Planet Computers fans, but for those, who just bought a good device for using it, there is no need in purchasing original devices just because of Planet Comptuters logo on it. Especially, if there is a lot of cheaper analogs around.

So, I start this topic to post here reports of experience with using such third party devices with Gemini PDA, to help others choose a device they need.

Please, post model names, links to the pages with description or where it could be purchased with your experience how it works with Gemini PDA.

I received my Gemini PGA about 2 weeks ago.

I found an interesting fact about its charging. A have 4 differrent wall chargers, which support Qualcomm Quick Charge.
One of them is native charger for YotaPhone 2. It supports Qualcomm Quick Charge 2.0 only, because YP2 supports it (it has Qualcomm Snapdragon 801 chipset onboard).

Other three are chinese QQC 3.0 chargers from AliExpress^
  1. Ordinary QQC 3.0 charger, I purchased first.
  2. Another one, I purchased later, 'cause it says it have more power (1.6A max @12V vs 1.5A normal chargers do).
  3. The one from VINSIC I purchased last together with powerbank. I purchased it because it has charge LED indicator.

Gemini PDA has Cortex (not Qualcomm) CPU, so it should not support QQC. Indeed, the one for YP2 and first two from AliExpress charge Gemini with normal 5V. Also there is no Quck Charge LED indicator on the one for YP2 is not lit.

But the last one (from VINSIC) have charge LED indicator burning bright (which means Quick Charge is active) gives 9.3 - 9.5 volts output (measured with special USB Type C cable with built-in digital voltmeter and amperemeter)! blink.gif

So, I wonder, if Gemini PDA officially supports Quick Charging? Of so, which type? And why it works with only one of my QQC chargers?
