If a SUPRUS electric lighter dose not work, please check the following: 

1.Don’t use a fast charger to charge the lighter. These fast chargers have built-in chips to control power, which may be vulnerable to hacking attacks that can cause power surges in the charger, which may damage normal electric devices.

2. Don't forget to close the slide out tip after use. 

3. Try charging the lighter by plugging it into the USB port of a computer.

4. Long-term inactivity will affect battery life.The battery needs to be charged at least once a month to activate the vitality.

5. The tips are made of heat-resistant ceramic (the ceramic does not burn). The lighter may not work properly when there is built up carbon and wax on these tips.  Please clean the tips regularly after use. 

If it still does not work, you can contact the SUPRUS team with the email: service@suprus-beauty.com to get a replacement lighter.
