Charger with excellent loading characteristics but also many drawbacks

neutral
- External Power Supply
- Charging current not einstllbar, gentle charging impossible

negative
- Very loud fan
- Go illumination lights should after last pressing the keys possibly after 1min from
- Small font on the display, nothing for older people
- Very short cable on the power supply
- Very little technical. Dokomantation how high such as the discharge?
- Capacity measurement and refresh function are mentioned in the documentation only, but not described
- The manual is very short and only by trial and error to understand
- The manual is in at least 20 languages, but so tiny that they can barely read, I have enlarged the German part copied

Conclusion
I use it only if I do charge batteries quickly, or want to measure the capacitance. Otherwise I prefer to take my old processor-controlled plug-in charger
