At the base, magnets are holding the device securely in place while connected to the magnetic USB charging dock.
Many electronic devices with magnets can affect each other. While charging on a laptop, JUUL can trigger a magnet inside your computer that puts it into sleep mode.
This won't damage your computer, but if it happens, try using an alternate USB port. JUUL should also be kept away from keycards, credit cards and other items with magnetic strips.
