The Accessible Talking Power Bank is a portable charger designed for users who are blind or have low vision. It features voice prompts and vibration feedback to announce charging status, battery levels, and low battery warnings, ensuring users can easily monitor their power without needing sight. It offers a compact, lightweight design for on-the-go use.

Features

Speech Output: Announces key actions like:
“Charging started” / “Charging ended”
“Power bank is charging” / “Power bank is fully charged”
“Battery low, please charge”
Battery level status (e.g., “100% remaining”)
This helps users understand what the device is doing without needing to see any display or lights.
Tactile Feedback (Vibrations): Vibrates once for:
Charging start/end
Low battery warning (repeats every 3 minutes when below 10%)
Confirmation of power bank charging
Vibration count (1–4) gives a quick way to identify battery level by touch alone, making it especially useful when speech is not practical (e.g., in noisy environments).
Battery Level Indicators: Users can check battery status via:
Voice announcement (“x% remaining”)
Vibrations (1–4 based on level)
LED lights (for sighted users or those with partial vision)
This helps users understand what the device is doing without needing to see any display or lights.
Port Layout and Orientation:
Clearly described orientation of ports with labels (USB A, USB C, USB Micro, Speaker)
Designed to minimize confusion, particularly with the speaker port, which could be mistaken for a charging port—this is clearly labeled as not for cable use.
Independence and Confidence:
A blind or low vision user can independently manage charging, know when the device or power bank is full or needs recharging, and avoid overcharging—all with no need for sight.
Battery capacity: 10,000 mAh (milliamp-hour)
Battery type: Li-polymer battery
