Design & development

The key to advanced performance

Because Maha designs its own microcontrollers, we can respond to the market with features no one else offers — engineered in-house from the silicon up.

Robust core technology

Designing our own microcontrollers lets us ship never-before-seen features fast.

Market & tech-driven R&D

We listen to customers and invest in fundamental technology to raise performance and cut cost.

Above-and-beyond safety

Meets and exceeds UL, CE, GS, C-Tick and PSE — with multiple-redundant protections.

Reliability

Verified with 25G HALT accelerated life testing and −40 to 80°C thermoshock.

Manufacturing

Production & testing, done right

Our state-of-the-art hub in Taiwan runs highly automated production and testing for high yield and throughput at a competitive cost. Every facility is ISO-9001 certified, plus UL, TÜV and other accreditations.

Every product is tested individually by automated systems — removing the human factor from quality control — then run through a rigorous burn-in and cycling sequence, with random in-production sampling for extra reliability and aging tests.

Our story

"Maha" means infinity

The story of Maha Energy didn't start with a glorious beginning or a big entrance. It's the story of a young couple with two little boys — first-generation immigrants realizing their American dream. Today, Maha Energy is a minority woman-owned small business with a big ambition: better power solutions for a better environment, for generations to come.

Among the first to introduce NiMH battery technology and tailor-made professional-grade chargers, the Powerex brand earned its reputation through years of hard work. Charles, armed with his electrical engineering degree, designed the legendary MH-C777 Universal Charger — whose movable contacts could charge virtually any battery. Next came the MH-C9000 WizardOne charger-analyzer, giving users full control over charging and analyzing AA and AAA cells.

The company kept pushing professional-grade chargers for those who demand the most, while driving NiMH capacity from 1550mAh all the way to 2700mAh today, with low self-discharge. Powerex now offers some of the highest-capacity, best-performing consumer rechargeables on the market — staying true to its values for over 30 years, with products that outperform and service that's second to none.
