How can one refill a Butane lighter?
To refill a butane lighter, first, ensure it's completely empty by purging any remaining fuel. Next, turn the lighter upside down and insert the butane fuel nozzle into the refill valve on the bottom of the lighter. Press the can of butane firmly into the valve for about 5-10 seconds. Allow the lighter to sit for a few minutes before using it to allow the fuel to stabilize.
