AirTab 15.6″ Portable Display Provides 2x USB-C Inputs (Crowdfunding)

AirTab Portable Monitor

While portable displays have been available as far back as at least 2012, they’ve become more popular in recent years as they can both offer a secondary display to your laptop, or add a larger screen to your smartphone. In the last two years, we’ve already covered BlitzWolf BW-PCM1, T-bao T15A, TAIHE Gemini (which ended up being a failure), Airview, and Desklab among others. But apparently, there’s room for more with the launch of AirTab, a 15.6″ portable touchscreen or non-touch monitor, on Kickstarter that’s already surpassed its $10,000 funding target. AirTab specifications: 15.6″ display with 1920×1080 resolution up to 60 Hz refresh rate; 4ms response time; 256 cd/m2 brightness Touchscreen – Air Touch model only USB – 2x USB-C ports Power Supply – Dimensions – 335 x 245 x 4.9 mm Weight – 500 grams AirTab comes with a foldable magnetic cover that allows the display to be used […]
