3-Min Read to Find out How we Made It
Smaller. Lighter.
In 2014, we set ourselves a challenge: make power banks 10% smaller and 10% lighter. Suppliers told us it was a "mission impossible". But like Tom Cruise, our engineers don’t believe in limits.
They ventured across disciplines and industries, pushing the boundaries of battery technology.
The result?
By June 2024, we unveiled TinyCell™ high-density batteries, achieving a 20% reduction in size and 15% in weight. Then came HyperStack™ Architecture in July 2024, pushing circuit stacking to the limit. And by October 2024, we launched TinyCell™ Pro, making everything even smaller and lighter.

Then came HyperStack™ Architecture in July 2024, pushing circuit stacking to the limit.
And by October 2024, we launched TinyCell™ Pro, making everything even smaller and lighter.
That’s how we created the smallest, thinnest, and lightest 10K, 20K, and 25K power banks on the market. We set the bar high — and then we crushed it.
Faster. Safer.
At INIU, we know your time is precious. Slow charging? No thanks. That’s why, over the last decade, we’ve relentlessly pursued faster charging speeds. We were among the first to adopt dual-way USB-C for speedier charging. We embedded 100W, 140W, and even 240W power delivery into our products, combined with the latest standards like QC 4.0+, PD 3.1, and Qi2.2.
At INIU, we’ve spent 10 years pushing limits. We made chargers smaller and lighter to redefine portability, and we made them faster and safer to redefine performance. This isn’t just talk — it’s a promise. Now, go ahead and feel the difference.
