Frequently asked questions:

  1. Can a metal housing be used?
    A metal housing would create a faraday cage, it would block the bluetooth signal and the strength would suffer.
  2. What are the dimensions of the device?
    The approximate dimensions of the device are: Length 9.8cm, Height 3cm, Width 2.9cm.
  3. How is the latency?
    According to my tests, there is no noticeable latency and SterlingKey can be used even for competitive gaming. Due to the nature of Bluetooth, outside factors might affect the performance, your mileage may vary.
  4. Will you support the device after the launch?
    SterlingKey™ includes a USB to Serial Chip, and you will be able to update the firmware using the Type-C port connected to a computer, in case a new firmware is available.
  5. How much does the battery last?
    A 21700 battery with 4900mAh capacity has been used and tested to last for nearly 24 hours of continuous use.
    Wired keyboards are not optimized to be used with batteries, since they are meant to be plugged in directly to a power source. For that reason they can draw a lot more power than actual wireless keyboards, and that unfortunately affects the battery life.
    1. After 5 minutes of inactivity the device goes into Sleep Mode, so the actual battery life depends on the use of each user
    2. Charging up to 80% takes around 2.5 hours. Charging slows down afterwards to preserve the battery health. A full charge takes around 4 hours using a good quality 5V-2A charger
    3. By using a 21700 battery, it means that it can be easily replaced if needed, with the drawback of taking up a bit more space
