Using this Platinum + Candlelight is a breeze. First, plug in the charging adapter. Connect the power trays using the linkable pin charging system if you want to charge multiple candles at once. Place the candles on the charging trays. The red light on the tray will show that the candles are charging, and when it turns green, they're fully charged. You can use them right away. For best results, charge the candles for at least 10 hours before the first use. When not in use, keep the candles in a cool, dry place. Avoid exposing them to extreme heat or moisture. If you notice any decrease in performance over time, just give them a full charge. Remember, it comes with a one - year warranty, so if there are any problems, contact us.
