The main unit requires a charging voltage of 25.2V. Only the original charger should be used. Overcharging is strictly prohibited. The remote control is charged via 5V USB.
The remote control operates at 868 MHz. If the signal is lost continuously for more than one minute during operation, the main unit will automatically shut down for safety.
Do not store the unit in environments exceeding 60°C. Do not use it in water temperatures above 35°C.
Operation is restricted to users aged 16 and above. Minors must use the device under adult supervision. Children must not clean or maintain the device independently.
It includes built-in overcurrent and overtemperature protection. If the unit suddenly stops running at full speed, stop operation immediately, allow it to cool down, and then restart it.
The wristwatch-style remote control requires pairing. The wired dive controller does not require pairing. Simply tighten the data cable connector to ensure a watertight seal and press the depth reset button before each dive.
6070 brushless motor.
Fully charge the battery before first use. If the device will not be used for an extended period, recharge it every three months. Charge only on a flat, non-flammable surface. A green indicator light on the charger indicates a full charge.

No. This inflatable kayak is not a life-saving device or rescue equipment. It is designed for recreational use only and must be operated under adult supervision. Do not leave the kayak unattended in or near water.
Inflation must follow the numbered valve sequence. Start with valve No.1 (seat), then inflate the remaining air chambers in order. Do not use high-pressure air compressors. Avoid overinflation, as excessive pressure may damage seams or air chambers.
This inflatable kayak supports a maximum load of approximately 390–485 lbs (177–220 kg) and is designed for 1–2 persons. Do not exceed the recommended capacity shown on the product label for safety and performance reasons.
Yes. All users must wear a certified personal flotation device (PFD) while operating the kayak. This is especially important for children, beginners, and non-swimmers.
Yes, night use is possible where permitted by local regulations. Navigation lights must be installed and used in compliance with applicable boating laws.
Avoid overinflation in low-temperature conditions. Air expands when exposed to heat or sunlight, which may increase internal pressure. Since this kayak does not include a pressure relief valve, users must monitor air pressure carefully.
This inflatable kayak is designed for sheltered waters, including lakes, calm rivers, and protected coastal areas with limited wind and wave conditions. It is not intended for rough offshore waters.
Before each use, check weather forecasts, wind speed, tides, and water currents. Always inform someone onshore of your planned route and expected return time. Avoid operating in unstable or severe weather conditions.
Not necessarily. Air pressure may change due to temperature differences. First check valve tightness. If pressure loss continues, use soapy water to identify potential air leaks.
Use the included repair kit. Clean and dry the damaged area, apply adhesive, and place a repair patch firmly over the puncture. Allow at least 12 hours to dry, then reinforce the edges and allow additional curing time. Do not repair while the kayak is inflated.
Store the kayak in a clean, dry, and well-ventilated area. Ensure it is fully dry before storage to prevent mold or material damage. It can be stored inflated or deflated. For long-term storage, deflation is recommended.
No. Do not use solvents, alcohol-based cleaners, or harsh chemicals, as they may damage the PVC material. Use mild soap and water with a soft sponge for cleaning.
Connect the paddle blades and shaft by inserting them into the connector and tightening securely. Ensure all locking points are firmly fixed before use.
Avoid areas with swimmers and divers. Maintain at least 50 meters distance from dive flags (Alpha flag) and comply with local boating safety regulations.
At least one passenger should understand basic kayak operation. All passengers must remain seated while in use. Standing on the kayak or sitting on the bow is strictly prohibited. Do not operate under the influence of alcohol or drugs.
