Material analysis of the Weten Rechargeable Personal Safety Alarm reveals a high-decibel piezo-electric transducer capable of producing a 130dB acoustic output. The device is powered by an internal lithium-polymer battery and includes a USB-C charging circuit, eliminating the requirement for disposable coin cells. A secondary visual alert is provided via an LED strobe utilizing pulse-width modulation (PWM).
Technical specifications indicate that the device operates as a localized deterrent with zero wireless connectivity (Wi-Fi, Bluetooth, or GPS). Performance is dependent on the mechanical pin tension and internal contact spring; fatigue in these components can lead to false triggers or activation failure. Battery self-discharge metrics suggest that the Li-Po cell requires recharging every 30 to 60 days to maintain sufficient amperage for full decibel output.
The chassis lacks an IP-rated dust cover for the charging port, making the internal electronics vulnerable to corrosion in high-moisture environments. It is designed for immediate, audible alerts to individuals in the immediate vicinity.
Technical recommendation: Perform a monthly pulse test by engaging the pin for one second to verify battery charge and transducer functionality.
If you require a system that notifies a remote party when a button is pressed, the Nestling Wireless Caregiver Pager is a more suitable choice.
