Update: there was some confusion when I made this video. I ordered the G2 model but when it arrived I couldn’t find any G2 branding on my device so I mistakenly thought I had been sent a G1 instead. In fact I had not. I did in fact receive a G2, it’s just that the G2 branding was very subtle and I missed it. The only indication seems to be a small “G2” on the back under the HP logo. Also I heard that the G2 model came with a USB-C connection, but that is wrong. My G2 has a USB-Micro connection, which I believe is standard.
