Case Study: a cell phone accessories company creates an ultra-slim wallet-sized charger with AJProTech

a cell phone accessories company creates a 7mm ultra-slim wallet charger with AJProTech

AJProTech partnered with a cell phone accessories company to address a market need for a truly portable charger. The challenge was to create an ultra-slim, wallet-sized device that was not only compact and durable but also featured an efficient power supply and was inexpensive to manufacture.

The solution implemented by AJProTech involved a complete electrical and mechanical design process, resulting in a charger with foldable prongs and an isolated AC-DC converter using a planar transformer for a low profile. AJProTech delivered a prototype that was just 7.5mm thick, optimized for BOM cost, and featured universal compatibility and safe charging. The project progressed to the electrical and mechanical prototyping phase and preparation of a pilot batch.
