Overview

Brief Introduction

Established in 2018, Shenzhen Waydoo Intelligence Technology Co.,Ltd. is a high-tech enterprise integrating research and development, production, and sales of water sports high-tech products. With the experience of the R&D team and technological expertise, Waydoo launched the first underwater scooter, Waydoo Subnado, through several technical innovations. Subnado adopts an advanced built-in battery design, integrating a 98wh lithium battery, brush- less motor, motor drive, control, and charging circuit inside an aluminum cylinder with a diameter of only 60mm, which significantly reduces the volume of the product. Across the industry, Subnado is the first to use the USB-C charging system, which supports fast charging protocols such as PD 3.0 and charges up to 100w for fast charging and charging other USB devices. The power system adopts the form of a small diameter injection pump that achieves propulsion efficiency while obtaining up to 6.5 kg thrust. The compact size and portability make it ideal for travel. Waydoo provides users with various accessories, such as board and arm accessories. With the board accessories, users can leverage the Subnado for propulsion power to suit a variety of scenarios. Users can fix the Subnado on the arm without occupying both hands with the arm accessories, which is convenient to use underwater.
The quick-release & installation system design enables users to switch between multiple scenarios.
The Subnado provides you with the perfect experience underwater.

Product Feature

  • Two-speed thrust: The high and low gear provides two-speed thrust options. Users can switch to the high or low gear by pressing the trigger twice quickly. Users will hear one beep if they successfully switch to low gear or two beeps if they switch to the high gear.
  • Super gear: Quickly press the trigger three times. When hearing three beeps, users successfully switch to super gear; Within 1 minute, press the trigger to start the propeller. The propeller will spin at the maximum speed and provide the ultimate thrust.

Note: After one minute, the unit will automatically exit Super gear and switch to the gear before Super gear. To re-enter Super gear, quickly press the trigger again three times.

Note: The battery SOC should satisfy a specific range to enter the setting gear. (refer to figure 1)
figure 1

Gear Battery SOC requirement
High gear >25%
Super gear >37.5%

Note: When the battery SOC is below 25%, it will automatically switch from high gear to low gear. When the battery SOC is below 37.5%, it will automatically exit super gear and switch to high gear.

  • USB-C fast charging: Use a standard USB-C interface charger to charge Subnado; support PD3.0, QC2.0, QC3.0, BC2.1, and other charging protocols. The maximum charging power can reach 100W.
    (Note: It needs to be supported by the charger and use of an e-Mark charging cable to reach 100W charging power).

  • Reverse charging: Subnado can be used as a power source to charge other devices. Reverse charging supports standard protocols such as PD3.0, PPS, QC3.0, QC2.0, and BC1.2. The maximum reverse charging power can reach 100W.
    (Note: It needs to be supported by the charging device and use of the e Mark charging cable to reach 100w charging power)

Charging

How to charge Subnado

Charging

  1. Select a charger that supports PD protocol to speed up charging.
  2. Open the waterproof cover (facing down to prevent water from falling in). Check for moisture around and inside the USB-C port. If there is water, it needs to be dried first; if there is seawater, it must be thoroughly cleaned with alcohol. After confirming that there is no abnormality, insert the USB-C charging cable to start charging.
  3. During the charging process, the power indicator is displayed circularly in the form of a marquee, and the number of lights indicates the current power.
  4. The speed of the marquee indicates the charging speed; the faster the marquee speeds, the faster the charging is.
