About YESPER

YESPER was founded in 2011 by an automotive enthusiast and amateur racer who understood firsthand the critical importance of reliability on the road. Years of track driving, long-distance travel, and real-world breakdown experiences revealed a simple truth: emergency power equipment is only valued when it is needed most — and failure is not an option.

Driven by this insight, YESPER was created with a clear technical mission: to develop powerful, dependable, and practical emergency energy solutions that perform under extreme and unpredictable conditions. This philosophy continues to shape our approach to engineering, testing, and product design.

YESPER’s R&D capabilities span battery chemistry, power management, control systems, and discharge technologies, supporting a comprehensive portfolio that includes sodium-ion batteries, automotive and heavy-duty replacement batteries, jump starters, portable power stations, and in-vehicle inverters.

Backed by 748 patented technologies, self-owned manufacturing facilities, and advanced production systems, YESPER delivers consistent quality, high performance, and scalable solutions for global markets.

Today, YESPER products are trusted in 100+ countries and regions, enabling drivers, professionals, and partners worldwide to stay powered, prepared, and confident — wherever the road leads.
