Hohm Tech ONYX OHM 2A Matrix Display Charger

Love the simplicity of Hohm SCHOOL series chargers?   Then here is the candy of chargers.  ONYX OHM is utilizing the same speedy output power of Hohm SCHOOL 2 (2A combined) but is equipped with the upgraded USB-C input.

It doesn’t stop there.  A Matrix I/O screen with a light-bleed shield is on board so it is clearly visible from multiple angles.  We’re just warming up here…

The ONYX OHM charging system is directly influenced by BEV (Battery Electric Vehicles).  How so you may ask.  Let’s list a few here: 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.

There’s more.  The ONYX OHM is equipped with an HPSC microcomputer with a 4.2V automated voltage (V) detection circuit.  Sounds cool, but not as cool 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 most everyone’s cells without 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.
