Charging
- The RejuvULite has a 1000mAh Li-Ion rechargeable battery.
- To recharge, simply set on a standard NFC charger. Which one? If you don’t have one around your house already, hundreds of models are available from stores such as Target, Best Buy, and Amazon. Links are provided with examples.
- When setting the RejuvULite on the charger, the charging indictor turn on, which is a small red light within the inner corner, as seen in the picture within the gallery.
- The charge time is dependent on the charger. In general, a full charge should be expected within 2 hours.
Power control
- Only on the RejuvULite, an advanced technique is used to only turn on full power when the light is shining directly onto a surface.
- This is a much appreciated feature that makes the product much more comfortable to use.
- When the RejuvULite is shining on an object, it will only output about 10% of the maximum power.
- When it detects it is covered by an object, it will ramp up to full power over 3 seconds.
- When it no longer shines on a surface, power will be immediately cut.
Reset and what happens when the battery is dead
- As a Li-Ion rechargeable battery is used, several methods are in place to ensure the product remains safe.
- There is a protection circuit that ensures the battery remains within expected operating conditions:
- A charge protection circuit ensures it cannot be overcharged.
- A discharge protection circuit completely disconnects the battery when its operating voltage drops too far, such as when not used for a long time.
- While the battery is likely to reconnect automatically, if it doesn’t this protection device can be reset by pushing a button through the small hole adjacent to the button. A paper clip, pin, or other small cylinder can be used to push this button.
- When the battery dies when operating, the device will turn off, but issue a double beep. This is to distinguish it from the standard beep occurring after two minutes of usage.
Timer
- When pushing the button, the RejuvULite will stay on for two minutes. It will beep after two minutes and turn off automatically.
