Electronics Design – Enterprise Tablet Charging Docks

Rapid development and product launch in ~ 5 months

Client – Portsmith Technologies – a designer and manufacturer of enterprise IT products

Expertise Applied


Portsmith needed to develop a new version of an existing charging dock for Samsung tablets, but did not have the internal capabilities to do so.


SGW Designworks developed a new product based on an existing Portsmith tablet dock, reducing the time and effort required to complete the project.

Results / Outcomes

  • Multiple prototype and testing cycles led to the optimal design and feature set
  • Portsmith launched the Tab Active Pro Charging Dock in early 2019


In late 2019, Samsung launched a new enterprise tablet, the Tab Active Pro. Portsmith Technologies had already established itself as the market leader in enterprise tablet charging docks. To follow the success of their Tab Active 2 dock, Portsmith engaged SGW Designworks to develop a new dock for the larger Tab Active Pro. The new charging dock would need to charge five tablets simultaneously, provide safe charging (via fault detection and voltage regulation), and be priced competitively for the market space.

SGW Designworks took an evolutionary approach to the design, using as many elements of the legacy Tab Active 2 dock as possible. The result was a rapid development effort and a simple yet highly functional product.

SGW Designworks developed this simple and safe charging product for the Samsung Tab Active Pro family of tablets. The product is based on the same proven design used in the successful Tab Active 2 dock and was built with similar mechanical and electrical specs as well as strong ABS plastic construction. These characteristics have been proven in installations in every use case imaginable worldwide. The product’s multiple bays eliminate the need for a single wall charger for each tablet. Each slot remains powered off until a Galaxy Tab Active Pro is inserted, and if a fault is sensed, a protection circuit shuts the slot down.
