The BEZGAR HJ821 2 Packs Remote Control Boat Set is designed for exciting water adventures with two high-performance 10-inch RC boats that let friends and family race together. Featuring powerful dual motors, these boats reach speeds of up to 15 km/h (9.3 mph) for fast-paced fun in pools, lakes, and calm saltwater. The advanced 2.4GHz anti-interference control system allows multiple boats to operate simultaneously without signal conflicts, making it ideal for multiplayer racing. Bright LED lights enhance visibility for evening play, while dual-speed modes let users switch between high-speed racing and extended cruising. Each boat includes a rechargeable 3.7V 1200mAh lithium-ion battery, delivering up to 50 minutes of high-speed use or up to 2 hours in low-speed mode under suitable conditions. The built-in water sensor helps protect the motors by activating the propellers only when the boat is in water. Designed for kids aged 8+ and adults, the HJ821 set combines durability, easy operation, and thrilling performance, making it a great choice for outdoor summer fun, family competitions, and gift-giving occasions.
