4Score 510 USB Charger

If you purchase a 4SCORE Day Pen, this USB compatible charger is already included. But, if you need an extra one, this is designed for our 510 thread Day pens. It features Auto Safety Shut Off, Rapid Charge, and an Overcharge protection chip. This just means it will charge as fast as possible, and stop charging once it’s ready to go. This keeps everything safe and working optimally.
