TAIHE Gemini 4K Portable Touchscreen Display

Portable displays have been available for a while, but they used to be fairly heavy, as for example, Gechic On-Lap Monitor 2501M 15.6″ portable monitor weighted 1.3 kg with cover. However in recent times, we’ve seen several such products – LAPSCREEN and DUO Add-on Display – launched with lighter designs, and the advance as USB type-C and power delivery make those even more attractive since a single cable can be used to transfer video, and power both the display and the host device. TAIHE Gemini is yet another option, but at 15.6″ is larger than the two aforementioned products, it is equipped with its own battery and kickstand, and comes in two variants with either 1920×1080 Full HD or 3840×2160 (4K UHD) resolution.
