Welfnobl IB-P1103 Waterproof 8-Gang Rocker Switch Panel with Dual USB
Built for Demanding Environments
The Welfnobl IB-P1103 is a waterproof 8 gang Switch Panel engineered for people who work and play where conditions get rough. Whether mounted on a bass boat cutting through morning spray or bolted inside an RV parked off-grid, this panel keeps every circuit within finger's reach. Welfnobl designed the IB-P1103 around one simple promise: reliable power control that survives salt spray, dust, and vibration. Backed by a rugged ABS+PC+Aluminum housing, it is the kind of equipment you install once and forget about — because it simply works.
Eight Rocker Switches, Total Control
At the heart of the IB-P1103 switch panel are eight independently labeled rocker switches, each with a crisp, tactile snap and a built-in LED indicator light in blue, green, or red. No more guessing which switch runs the navigation lights and which one feeds the live-well pump. Each rocker is sealed against moisture and rated for DC 12V/20A or 24V/10A service, so you can run lights, pumps, radios, and auxiliary gear from one organized hub. Welfnobl laser-etches every label for long-term readability.
Dual USB Charging That Keeps Devices Ready
A modern vessel or work truck lives on charged electronics, which is why the dual USB charger matters. The IB-P1103 delivers 5V 2.1A + 2.1A output — a full 4.2A of combined charging current — enough to power a chartplotter and a smartphone at the same time without slow-down. Welfnobl tuned the USB circuitry for stable, low-ripple charging, protecting battery health over seasons of use. When your GPS and phone both sit at 5% at dusk, two fast ports side by side stop being a luxury.
A Digital Voltmeter You Can Trust
Battery failure rarely announces itself — unless you have a digital voltmeter watching your back. The IB-P1103 features a bright blue-backlit display that reads input voltage across the full 12-24V DC working range in real time. One glance tells you whether your battery bank is healthy, charging, or quietly dying. Welfnobl calibrates each meter for accuracy within tight tolerance, because a voltmeter that lies is worse than no voltmeter at all. Monitoring your 12V/24V electrical system becomes effortless.
True IP66 Waterproof Protection
Rain, deck wash-downs, and engine spray are facts of life on the water. The IB-P1103 carries a genuine IP66 waterproof rating, sealing the entire faceplate against powerful jets and heavy seas. The waterproof rocker switch panel construction combines an aluminum frame with corrosion-resistant hardware, so salt air won't eat it alive. Welfnobl pressure-tests this design rather than assuming it passes. Compared with unsealed generic panels that corrode within a season, IP66 protection is the difference between replacing gear annually and installing it permanently.
Circuit Breaker Safety You Can Rely On
Every circuit on the IB-P1103 routes through integrated circuit breakers with reset buttons, giving you resettable overcurrent protection without hunting for spare fuses at midnight. If a short or overload occurs, the breaker trips in seconds — protecting your wiring harness, your battery, and your vessel. Rated for 12V/20A and 24V/10A per circuit, this pre-wired switch panel with circuit breakers meets the demands of serious electrical loads. Welfnobl includes a cigarette lighter socket (12V/24V) for portable accessories, rounding out a complete power distribution solution.
Wide 12V/24V Compatibility
Flexibility defines the IB-P1103 pre-wired switch panel. It accepts an input voltage of 12-24V DC, making it equally at home on 12V boats, bass boats, pontoons, and jon boats as on 24V trucks, buses, and industrial equipment. Measuring a compact 150×110×30mm, it fits tight helm consoles and cramped dashes where space is scarce. Output is steady 12V DC across switched circuits. Welfnobl builds one panel to cover your entire fleet — boat, RV, trailer, and work truck alike.
Pre-Wired Installation, Ready Out of the Box
Nobody enjoys splicing eight circuits by hand, which is why the IB-P1103 arrives pre-wired with clearly identified leads. Connect the main positive and negative, mount the panel with standard hardware, and the system is live. The included cigarette socket, dual USB ports, and digital voltmeter are all integrated into the harness. From marine and automotive to RV and off-grid solar setups, this Welfnobl switch panel turns a weekend wiring project into an afternoon task — professional results without the professional labor bill.
