Hohm Tech - Onyx Ohm Charger 2 Slot, with screen

The ONYX OHM charger combines advanced technology and the highest safety standards to make the charging process of 3.6V and 3.7V Li-ion Batteries (NMC, LIR, INR, ICR) efficient and safe. Through the real-time display of the state of charge (SoC), it enables precise monitoring based on the actual state of the battery. Equipped with a high-precision single-chip microcontroller (HPSC) and a special detection circuit, the device automatically shuts down when fully charged to protect battery life.

Each of the independent charging slots is equipped with comprehensive safety precautions: protection against reverse polarity, short circuit, lower voltage, incompatible battery type, overcharging, overheating and DC overload.

With its USB-C input, the ONYX OHM offers universal flexibility and adapts intelligently to the output power of the adapter used. In addition, the ONYX OHM has a preconditioning function that gently charges weak Li-ion batteries with a 200mA current until they reach 2.8V. With precise PWM control, constant current and constant voltage (CC/CV), a safe and stable charging process is guaranteed. Thanks to the high-contrast matrix I/O display, the charging information can be easily read from any angle. The ONYX OHM displays the real-time charge status, which may naturally differ from other Chargers as the device reflects the actual battery capacity.

This charger is ideal for users who require high precision and comprehensive protection when charging cylindrical Li-ion batteries.
