School 2A
The world spoke, we listened and took action. After 11 month of R&D on the operations and features…we present Hohm SCHOOL2A. What is the 2A? It’s two things: 2 x bays & 2 x amp (2A combined output capability). There is no need for a screen on this charger. It is 100% autonomous. It is equipped with our BLD1 System, which automates the step-up/down output so both small and larger cells charge at the proper rate. Even li-ion batteries with or without PCB/PCM3 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.

Applying more forward-thinking towards safety & performance, we integrated input voltage regulation. This is safety 101 here. This allows the charger to not stress or damage USB adapters no matter the power supplying device. The fact is simple: today’s li-ion batteries need precise voltage and amperage delivery to ensure long reliable performance & life…Say hello to Hohm SCHOOL2A, the smarter charger.

UNO
Simplicity in a single-slot form. We present Hohm SCHOOLUNO. 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:
  • BLD1 System – Automates charge amplification & reduction on li-ion cells
  • 0V2 Activation – among lowest Volt Recognition points ever to ensure low charge cells get back to where they ought to be (4.2V)
  • Input-Power Autonomous Regulator integration (no more stressing USB power adapters or ports)
  • 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] over charge; B] short-circuit; C] wrong battery type detection; D] reverse polarity
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, consistency, and safety.
