Power Bank
The Data Walker uses an external USB-C power bank that is user-replaceable and can be charged independently from the device.
Power Bank Specifications
- Type: External USB-C power bank (Kioson or equivalent)
- Capacity: 5000mAh
- Output: USB-C PD, 3A
- Display: LED percentage indicator
- Runtime: Multiple days of clinical use on a single charge
- User-replaceable: Yes - standard USB-C power banks are compatible
User-Replaceable Power
Unlike devices with internal batteries, the Data Walker uses a removable USB-C power bank. You can swap in a charged power bank instantly or charge it separately from the device.
Charging the Power Bank
The power bank can be charged while attached to the device or separately:
Charging While Attached
- Connect a USB-C cable to the power bank's input port
- Connect the other end to a USB power source
- The LED display shows charging progress
- Charging is complete when the display shows 100%
Charging Separately
- Detach the power bank from the Data Walker
- Connect to any USB-C charger
- Charge to desired level
- Reattach to the device when ready
During Clinical Tests
For accurate measurements, avoid having charging cables connected during clinical tests to prevent cable interference with walker movement.
Reading the LED Display
The power bank has a digital LED display that shows the exact battery percentage:
- 100-50%: Plenty of charge for multiple sessions
- 50-20%: Good for several more tests, consider charging soon
- Below 20%: Charge before next clinical session
- Display off: Press button on power bank to wake display
Battery Best Practices
- Keep a spare: Have a second charged power bank ready for busy days
- Charge overnight: Plug in at the end of each clinic day
- Avoid full discharge: Charge when battery drops below 20%
- Temperature: Charge at room temperature (15-25°C / 59-77°F)
- Quality chargers: Use reputable USB-C chargers rated for at least 5V/2A
Replacing the Power Bank
The power bank is a standard component that can be replaced:
- Recommended: Kioson 5000mAh USB-C power bank (or equivalent)
- Requirements: USB-C output, 5000mAh minimum, compact form factor
- Where to buy: Available on Amazon and other retailers
Instant Swap
If the power bank runs low during a busy clinic day, simply detach it and attach a fully charged replacement. No downtime required.
Troubleshooting
Power bank not charging
- Try a different USB-C cable
- Try a different power source/charger
- Ensure the cable is connected to the input port, not output
- Press the button on the power bank to check if it responds
Device not powering on
- Check power bank charge level (press button to see LED display)
- Ensure power bank is firmly connected to device USB-C port
- Try a different power bank if available
- Check USB-C port on device for debris
Power bank drains quickly
- Normal runtime is multiple days - rapid drain indicates a failing power bank
- Replace with a new 5000mAh USB-C power bank
- Lithium batteries degrade after 2-3 years of heavy use
