1050NP Ultrasonic Inverter — 2000W High Power, 3 Modes, 6.56–16.4ft Effective Range, 12V Battery Compatible for Freshwater Fishing

Compact and portable: The unit’s small footprint (7.87*4.92*2.76in) fits into a tight storage spot and is easy to carry for outdoor use. Powerful conversion: With 2000W output it converts direct current into high-frequency alternating current; a built-in pure copper transformer and a microcomputer numerical control chip deliver stable, long-term operation. Effective fishing technology: Ultrasonic inverter technology is used to incapacitate fish at distances between 6.56-16.4ft, improving your catch success. Safety features: Includes full current limiting protection plus intelligent pulse technology to help ensure safer operation. Precise control and feedback: A digital display shows battery level, real-time voltage, and frequency. You can select among three modes — powerful mode, mixed frequency, main frequency — and use the front knob to fine-tune the frequency to match conditions. Wide compatibility: Designed for 12V20AH or above batteries and compatible with lithium batteries, car batteries, and tricycle batteries; the unit adapts to both high and low voltage scenarios. Thermal management: An internal heat dissipation fan together with large cooling holes rapidly remove heat to keep the inverter running smoothly and extend service life.
