Hohm SCHOOLUNO Single  2A Micro-USB Charger
  • 2A | 10W TURBOCHARGED

  • Plug & Play ready out the box.  Connect to your preferred USB 5V Power Adapter and it’s ready to work

  • Built from Fire-Retardant materials adds to the list of safety features

  • Unilateral design derived directly from the high-quality SCHOOL charger lineup

  • Long-throw sliders allow cells up to 71mm length

  • Simplistic LED system.  RED = charging; GREEN = charged

  • Optimal contact with the top portion of the cell with its Multi-Groove positive post

  • Has the safety features one would expect from Hohm Tech.  Enabled with:  1. PCB Overheat Prevention;  2. Short-Circuit Prevention;  3. Reverse-Polarity Prevention;  4. Over-Charge Prevention

  • Li-ion sizes: 26650, 22650, 21700, 20700, 18650, 18490, 18350, 17500, 16430 (RCR123), and more

  • Charging with proven CC & CV (constant current & constant voltage)

  • Just like its bigger siblings, it utilizes the integrated IPR System.  IPR= Input Power Regulator.  This enables the charger to withdrawal demanding high power from underpowered USB Power Adapters

  • Designed specifically for protected and non-protection 3.6v/3.7v Li-ion (lithium-ion) cells

  • Big-Bore Slot to secure both small & large Li-ion cylinders (easily handles 26650 girths)
