OEM/ODM Portable Power Bank Manufacturer
Why carry around a tangled bundle of chargers when a single book can do it all? At Shenzhen Gina Technology Co., Ltd., we design and manufacture the ultimate multi-functional business accessory: the custom Power Bank Diary. Built straight into a premium A5 corporate notebook, our smart diaries effortlessly solve workspace battery anxiety while giving your clients a high-end tool for daily productivity.
We pack massive, retail-grade battery capacities (up to 8,000mAh–10,000mAh) directly into the spine and covers of our journals. Equipped with integrated ultra-fast 22.5W wired charging cords and smooth 15W magnetic wireless alignment drops on the cover, these tech notebooks keep smartphones, tablets, and wireless earbuds completely powered during marathon meetings or long flights.
We love working with brand managers to make these truly unique. Every single power bank diary we build can be heavily customized with eye-catching Glow Logo Tech that beautifully illuminates your client's corporate branding whenever a device is charging. From premium leather options to sustainable materials, our Shenzhen manufacturing facility manages everything from rapid prototyping to strict QC testing.
