What would you like to know about the ASIWO U1 before purchasing?
No, it will float slightly on the water.
No, it’s not safe. Submerging the battery pack or replacing it underwater can damage the connectors between the battery pack and the main board.
Yes, the battery, motor, and main board connectors are waterproof. However, water will enter the body during use.
Place the ASIWO U1 sea scooter in the water. When you're ready to begin, press and hold both triggers to start the propeller. To stop the propeller, simply release the triggers.
Note: You must hold both handle switches to power on the scooter; holding only one will not activate it.
3-Gear Switch: Use the left handle to shift down and the right handle to shift up.
Important: When changing gears, do not release both handles at the same time. Always hold one handle while using the other to shift gears.
- Before starting, check if the Bluetooth indicator on the controller is on. If it is, the U1 on your SUP is powered on and ready for Bluetooth control.
- Once your SUP with U1 is in the water, press the gear-1 button for a smooth start. You can then press the gear-2 and gear-3 buttons to increase speed as needed.
- Safety Instructions for SUP Receiver and Security Locker: Attach the receiver to the tail of the SUP and ensure it is secured on top to prevent it from falling into the water and interfering with the Bluetooth signal. Also, install the security locker on the receiver and attach it to your leg. If you fall into the water without the security locker connected, the U1 will automatically stop.
Sorry, the ASIWO U1 doesn't support the swing foil board.
Underwater scooters can accumulate salt crystals, sand particles, and chlorine or acids from swimming pools, all of which can cause corrosion. To prevent damage, it's important to rinse the scooter with fresh water within a few minutes after your dive. The longer corrosive materials remain, the greater the risk of damage.
Ensure the battery and main board connectors are completely dry before storage; otherwise, they may be damaged by oxidation from electrolysis after powering on.
The issue may be caused by sand particles or salt crystals in the motor compartment. Try submerging the machine in water for a few minutes, then start it repeatedly to restore normal motor function.
No, We suggest you contact your local dealer to replace the battery pack.
To extend battery life, it's recommended to fully charge the battery pack after using the underwater scooter, store it separately, and recharge it every 2 months.
If there is corrosion on the battery's contact point, such as a green or white layer, follow these steps:
Step 1: Mix vinegar and salt, then wipe the battery's contact point with the mixture. This will remove the corrosion and restore the shine.
Step 2: After cleaning, allow it to dry naturally. If storing for an extended period, apply a small amount of wax or Vaseline to protect it.

Yes, it supports for Kayaks. The weight of the ASIWO U1 battery is 1.87kg.
We will launch an adapter for Kayaks and an external outboard battery. The external outboard battery may weigh less than 10 kg.
