The product has been slightly modified. The revised version is a circuit board without a chip, and the function of timing shutdown for 60 seconds after a button press has been canceled. It is now set to turn on the pump upon pressing the button, and the pump will stop upon pressing it again. During transportation, if the product is bumped into the switch, it will continuously operate with a sound, and it will stop working after about two hours. Consumers must charge the product before their first use.
