Commercial Restroom Problem
- 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 maintenance costs
Commercial Restroom Solution
AeroCharge Long-Range Wireless Power allows wireless sensors to operate continuously
- AeroCharge patented wireless power technology allows commercial restroom fixtures to be powered on at all times and never run out of charge
- Fixtures 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
