I agree with the suggestion of not having any labels on the power supply. Surely, an owner will quickly learn the meaning of the three LEDs and not need to read the labels when checking the status of the charger.
After all, there didn't seem to be a need to have labels for the display on the LDR preamps which is much more complex and multifunctional.
Think elegance, simplicity, minimalism. Just my two cents.
