Fitness Equipment Problem

Fitness equipment display and sensor battery life is costly and limits usage

  • Short battery life (less than 6 months) causes operational gaps, poor user experiences, and limits scaling of products
  • Replacing batteries is highly inconvenient and increases operational costs

Fitness Equipment Solution

  • AeroCharge patented wireless power technology allows fitness equipment to be powered on at all times and never run out of charge
  • Devices charge over-the-air up to 12 feet away from the 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)

Use Cases

Cable Machines

Rowing Machines

Cycling Bikes

Non-motorized Treadmills
