Hohm Tech School 4 Battery Charger Hohm Tech

USB-C 4 AMP continuous power supply and stability made it possible for Hohm SCHOOL4 to do what it does so well.

Thinking outside the box, while keeping simplicity and user-error prevention at the forefront with safety features. 18 months of R&D led us to develop an extremely capable charger that makes other chargers look stupid. It has a 3-tier amp BLD (battery length detection) System; has a variable input voltage IPR (input power regulator) feature. This ELIMINATES USER ERRORS, and keeps them and their li-ion batteries moving forward without delay. This is simplicity at its best, while not forfeiting usable amperage or precision.

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 proper rate (0.5A, 1A, 2A per channel with 4A total distribution). Even li-ion batteries with a 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 targeted towards safety & performance, we integrated input voltage regulation. This is safety 101 here. This allows charger to not stress or damage USB adapters no matter the power supplying device. Fact is simple: today’s li-ion batteries need precise voltage and amperage delivery to ensure long reliable performance & life…Say hello to Hohm SCHOOL4, the ‘Professor’ of Chargers.
