FAQ
Q: Can I charge different types of batteries at the same time?
A: Yes, each of the 4 slots is independent. The Hohm School will automatically adjust the power for each battery individually.
Q: Does it support 21700 batteries?
A: Absolutely. It is designed to fit and safely charge 18650, 20700, 21700, and even larger 26650 cells.
Q: Why are there no buttons or screens?
A: The "Hohm School" philosophy is to make charging foolproof. It uses an internal micro-processor to handle all settings automatically, ensuring safety without user error.
Q: How do I know when my batteries are done?
A: The LED indicator for that specific slot will turn from Red (charging) to Green (fully charged/standby).
