It combines the charging capability of its bigger brother Hohm SCHOOL2 but combines that power into 1 single slot. That is 2000mA (2A output) of single-cell charging speed. We did not go with 3A as this often accelerates cell degradation and reduces cycle life. 2A charging is a speedy yet conscientious charging speed for today’s lithium-ion cells. There is no need for a screen on this charger. It is 100% autonomous. It is equipped with the IPR System1, which automates the step-up/down output to match the power adapter that supplies the power. Whether you use an older 0.5A or a newer 2A (or greater) power supply/adapter, the Hohm SCHOOLUNO will do a proper job. Even li-ion batteries with or without PCB/PCM2 are easily balanced to the correct voltage. This ensures today’s small li-ion batteries’ chemistry integrity is not compromised, allowing them to get the cycle life they deserve.

Equipped with:

> IPR System – no more stressing USB power adapters or ports
> Low-Voltage Activation – If a cell has low voltage and is not charging on other chargers, let this charger go to work for you.
> Compatible with ALL li-ion cells from as short as 30mm to as long as 71mm
> LED indicator that reports color and blink variation for quick/easy readout
> PCB/PCM3 compatible so even protected cells aren’t left out in the cold
> Protection 101: A] Short circuit; B] PCB overheat C] Reverse polarity; D] Over-charge prevention
