Motorized Shades Problem

Battery life of motorized shades creates a poor user experience

  • Short battery life (less than 6 months) causes outages and limits scaling of products
  • Replacing and recharging batteries is highly inconvenient

Motorized Shades Solution

  • AeroCharge patented wireless power technology allows motorized shades to be powered on at all times and never run out of charge
  • Shade battery charges over-the-air up to 12 feet away from power source
  • System operates in unlicensed spectrum without causing interference to other wireless electronics
  • Compliant with FCC safety standards
  • No line of sight needed

Product Integration

  • Receiver is integrated on one or multiple sides of a device
  • Delivered power at 6 feet: 2 mW per device (50 mWh - 6V / 8 mAh over a 24 hour period)

Uses Cases

Motorized Shades

Self-Dimming Window Glass

Motorized Awnings
