Qoitech's Otii Ace Pro is a development tool for energy optimization of battery-driven and energy-harvesting devices. It is an isolated programmable power supply and a measurement unit that can precisely source voltage (up to 25 V) or current (up to 5 A) and simultaneously measure voltage and current with a high sample rate (up to 50 ksps) and low step size. It computes power and energy that enables engineers and developers to easily see and optimize their devices' energy consumption and battery life under test. Otii Ace Pro can be upgraded with Otii Toolboxes, software licenses that elevate the instrument into specialized tools such as battery profiler and simulator, or automation tools. It can be used in product development, test and verification, quality assurance and maintenance (for example as part of continuous integration set-up), and in technical sales.

The Otii Ace Pro measures 10.95 cm x 14.45 cm x 4.45 cm (W x L x H) and weighs 450 grams. It is designed for the office, lab, usage at home and field measurements. The innovative mechanical design allows for efficient heat dissipation, so no fan is needed, resulting in low noise.
