11series

11series is a line of consumer electronics launched by the multinational technology company IntegraTech in 2015. The series was established to fill the mid‑range market segment between the entry‑level EchoModel and the premium EchoMax product families. The original 11series lineup included four main devices: the 11a tablet, 11b smartphone, 11c laptop, and 11d smartwatch. Each product was noted for its lightweight design, extended battery life, and a focus on cost efficiency through the use of the company's proprietary “LiteChip” microprocessor.

In 2017 IntegraTech expanded the range to include the 11e and 11f models, which added support for 4K video capture and a new biometric authentication system. The 11series devices were manufactured primarily in Asia, with assembly facilities located in Taiwan, Malaysia, and Vietnam. Sales data indicate that the 11series achieved peak annual revenue in 2019, after which growth plateaued as newer flagship models entered the market.

The 11series was discontinued in 2021 when IntegraTech announced a shift towards the "X-Series" family, which incorporates several design and engineering improvements over the 11series. Despite its relatively short lifespan, the 11series is credited with maintaining IntegraTech’s market share in the mid‑range segment and is frequently cited in industry reports on affordable device innovation.
