<\/figure>\nSteasy\u00ae gently and evenly heats pre-cooked meals using steam \u2014 without a microwave and, thanks to its Battery-powered design, without needing an outlet. A small amount of water inside the device is heated to generate steam, which warms the food in the inner tray in about 15 minutes without drying it out. This gentle steaming process helps preserve flavor, texture, and valuable nutrients.<\/p>\n<\/div><\/div>\n\n\n\n
\nWith its high-quality materials, smart app control, and fully mobile design, Steasy\u00ae is the ideal companion for the office, university, construction sites, or on the go \u2014 delivering warm meals in excellent quality whenever and wherever you want to enjoy them.<\/p>\n<\/div>![\"\"](\"https:\/\/www.jauch.com\/blog\/wp-content\/uploads\/2026\/04\/Jauch_Steasy-outside-825x1024.png\")
<\/figure><\/div>\n\n\n\nThe update: Jauch now supplies the cells and the complete Battery production<\/h2>\n\n\n\n
In the first product version, Nexenic used standard 18650 and later 21700 lithium ion cells. Today, the Swiss start-up <\/a>relies entirely on Jauch\u2019s own 21700 lithium ion cells. Depending on the configuration, Jauch\u2019s lithium ion cells<\/a> offer either high continuous discharge currents of up to 45 A or highly energy\u2011optimized variants with up to 5,000 mAh. They also deliver excellent cycle stability and incorporate integrated safety mechanisms such as the CID.
In addition, they provide significantly higher capacity, ensuring that Steasy\u00ae continues to reliably achieve its 15\u2011minute steam\u2011cooking time \u2014 while the device as a whole benefits from a substantially longer service life<\/p>\n\n\n\n![\"\"](\"https:\/\/www.jauch.com\/blog\/wp-content\/uploads\/2026\/04\/Jauch_lithium-battery-Steasy-1024x389.png\")
<\/figure>\nWhat this means for users and the environment:<\/p>\n\n\n\n
\u2022\u202flonger device lifetime
\u2022\u202ffewer Battery replacements \u2192 less waste

Made in Villingen\u2011Schwenningen: Battery Assembly at Jauch<\/h2>\n\n\n\n![\"\"](\"https:\/\/www.jauch.com\/blog\/wp-content\/uploads\/2026\/04\/Jauch-Steasy-battery-production-1024x683.jpg\")
<\/figure>\nAnother major change: The complete lithium ion Battery is now manufactured at Jauch\u2019s headquarters in Villingen\u2011Schwenningen. In our in\u2011house Battery production<\/a>, the cells are measured, sorted, assembled, and final tested. Thanks to automated welding processes, the Battery packs can now be produced in Germany with exceptional efficiency and consistently high quality \u2014 a clear advantage for production and series reliability.
The close proximity is a real benefit: Nexenic is located in the Zurich\/Winterthur area, and Villingen\u2011Schwenningen is only about 70 kilometers across the border. This allows in\u2011person meetings, testing, and coordination to take place quickly and without complication.<\/p>\n<\/div><\/div>\n\n\n\nFast availability: Increased supply security through in\u2011house production<\/h2>\n\n\n\n
Since Jauch now manufactures the Battery packs itself, availability is significantly higher and no longer dependent on external manufacturers. Nexenic benefits from:<\/p>\n\n\n\n
\u2022\u202fstable delivery times
\u2022\u202frapid prototype builds
\u2022\u202fdirect engineering contact
\u2022\u202ffull transparency throughout the production process<\/p>\n\n\n\n
Certified at the Jauch Test & Certification Center: UN 38.3 included<\/h2>\n\n\n\n
The Steasy\u00ae Battery is fully tested at Jauch\u2019s in\u2011house test and certification center<\/a>. This also includes the UN 38.3 transport test, which is mandatory for shipping a lithium ion battery worldwide. The tests simulate transport-related stresses such as pressure, temperature changes, shocks, and vibration.<\/p>\n\n\n\nWith Jauch cells and full Jauch certification, the entire Battery system is now qualified and safeguarded from a single source.<\/p>\n\n\n\n
On\u2011site insights \u2013 a technical conclusion from Reto Muhl<\/h2>\n\n\n\n
Reto Muhl, CTO and co\u2011founder of Nexenic, personally visited the Battery assembly operations in Villingen\u2011Schwenningen \u2014 and came away impressed: \u201cThe Battery production at Jauch is very well structured and exceptionally clean. The entire workflow is designed for reproducible quality.\u201d<\/p>\n\n\n\n
His key points:<\/p>\n\n\n\n
\u2022 Each individual cell is electrically measured before being installed.
\u2192 Benefit for Nexenic: Maximum pack consistency, long\u2011term stability, and a lower failure rate.<\/p>\n\n\n\n
\u2022 High level of automation thanks to modern spot\u2011welding machines.
\u2192 Benefit for Nexenic: Precise, repeatable welding points and therefore high mechanical robustness.<\/p>\n\n\n\n
\u2022 Clear process steps and quality checks at every stage.
\u2192 Benefit for Nexenic: Transparency, full traceability, and reliable series production.<\/p>\n\n\n\n
Conclusion: More performance, more quality \u2014 all from a single source<\/h2>\n\n\n\n
With the Jauch 21700 cells, the production of the Battery pack in Villingen\u2011Schwenningen, and the certifications conducted in Jauch\u2019s own test and certification center, Nexenic now receives a fully optimized Battery system that aligns perfectly with Steasy\u00ae\u2019s premium standards. The user experience improves \u2014 and with European production, Nexenic simultaneously strengthens regional value creation.<\/p>\n\n\n\n
