Mr.GadgetsShenzhen is a city so developed that it is called the “Silicon Valley of China.”
Many recent new brands and manufacturers originate from Shenzhen.
It is also one of the “four major cities” of mainland China, known as “Bei-Shang-Guang-Shen.”
Ms.GadgetsBei is Beijing, Shang is Shanghai, Guang is Guangzhou, and Shen is Shenzhen.
The manufacturing country is also China
The products are also manufactured in China, just like the company’s location.
History of VOLTME

The company has over 20 years of experience in the charging field and has provided OEM supply to multiple famous brands. Aiming to “promote technological innovation and provide customers with more enjoyable, comfortable, and creative products and services,” they established their own brand, “VOLTME.”
Mr.GadgetsOEM means manufacturing products for other brands. Incidentally, they have reportedly also handled OEM production for a certain famous “Company A.”

Ms.GadgetsThe fact that they can offer a 24-month warranty shows how confident they are in their products!
Mr.GadgetsWarranty periods are proportional to confidence in the product, after all.
Proprietary V-Dynamic technology, next-generation GaN III technology


V-Dynamic is a technology independently developed by VOLTME. It is compatible with charging standards such as USB PD and Quick Charge, allowing the charger to intelligently manage the output and temperature of each port, enabling more efficient charging.
Additionally, VOLTME USB chargers adopt GaN III (Gallium Nitride).
GaN III has the benefit of reducing the time required to fully charge a device. It also supports “USB Power Delivery (USB PD),” a charging standard that enables rapid charging with high output up to 140W, which can reduce charging time.
Furthermore, it features excellent thermal conductivity and heat dissipation, resulting in less heat generation compared to conventional silicon chargers, higher energy efficiency, and the ability to maintain high output while remaining compact.
Mr.GadgetsSo, thanks to this high level of technical capability, they can create compact and powerful products!
