Easy Chester Ultimate: guided charging and safety tests in the field
Easy Chester Ultimate brings charging tests, communication checks and electrical safety tests into a guided, portable workflow for work at the charging station.

From connection to test report
Connect the system to the selected AC/DC interface, choose the required tests and follow the guided sequence through execution to the report.
Touchscreen, transport case and PDF report
Use the 10.1-inch touchscreen to operate the tester at the charging station. The published reference weight of the system in its transport case is 15.7 kg. A configurable PDF report brings the test results together. Interfaces, safety tests and maintenance services are selected as part of the system configuration.
The product’s development
The Mini-Charger-Tester has been available since 2016. In 2024, it evolved into Easy Chester with modular hardware and broader charging-interface support. Generation 2 followed in 2025, extending the platform and load options. Ultimate continues this development with guided operation and an integrated field-testing workflow.
