battery life.
Deliver quality.

Empower your electronics development with cutting-edge power analysis, battery simulation, battery and energy harvesting testing.

Unlock long battery life of embedded and IoT devices in three steps

We can show you how.


Profile, analyze and refine your embedded and IoT application and devices for low energy use.


Profile batteries and use battery simulations for your specific application to find the right match.


Test your energy sources, from batteries to energy harvesting, for your specific usage to ensure best battery life.

We can show you how.

Otii Ace Pro

A complete solution for energy profiling and optimizing embedded devices, and simulating batteries to ensure the perfect match.

Otii products are used by developers and teams in 3500+ companies in 65+ countries

“Can’t imagine firmware development now without using an Otii Arc, and Otii Automation Toolbox allowed us to automate our production power profiling during the final test.”

Mathew Key, CTO at Isansys

“Thanks to Otii, we have been able to reduce our Strips current consumption even further to reach more than 10 years battery life. Every developer should have Otii Arc.”

Mats Pettersson, CTO at Sensative

“Working with Qoitech and establishing this low-power mindset certainly enriches the LoRaWAN community.”

Wienke Giezeman, CEO at The Things Industries

“If you are looking into optimizing your IoT device for low-power design, reach Björn Rosqvist from Qoitech, I cannot express how much energy we saved with the Otii Arc.”

Tal Klinger, Hardware & System Engineering Team Lead at Trax Retail
