Do you love the simplicity of Hohm SCHOOL series chargers from Hohm Tech? So do we, which makes this one the candy of chargers. This is the ONYX OHM, and it utilizes the same speedy output of Hohm SCHOOL 2 (2A combined) but is upgraded with USB-C input. It doesn’t stop there. It is equipped with a Matrix I/O screen with proprietary Light-Bleed Shield so it is clearly legible from multiple angles.

The ONYX OHM charging system is directly influenced by BEV (Battery Electric Vehicles). Wonder how so? Let’s list a few: 1) the displayed SoC (State of Charge) is based on Real-time & Real-world charge % like today’s EV (Electric Vehicles); 2) Omits stratagem data from displaying; 3) Integration of imperative safety features including
low-voltage preconditioning, DC overload, overcharge prevention, reverse polarity, cell fault detection, short-circuit prevention, and fire incubation.
If you thought Hohm Tech was done there, you would be wrong. The ONYX OHM is equipped with an HPSC microcomputer with a 4.2V automated voltage (V) detection circuit. Sounds nice, but not as nice as the efficient PWM control technology making CC & CV promote an extra layer of reliable charging. Last but not least, the ONYX OHM uses >71mm slots to ensure it charges everyone’s cells without any fitment issues. Every Hohm Tech product is tested and certified by the rightful authorities/laboratories and accredited entities to achieve Compliance & Certification of: CE, ROHS, FCC, Air/Sea Transport, and is backed by Industry Leading PLI. We do not cut corners. We deliver what we promise… chart-topping performance, capacity, and safety.
