This aluminum-finished panel is made for vehicles and marine craft that need reliable switched power plus convenient device charging and voltage monitoring. It fits cars, trucks, RVs, ATVs, UTVs, trailers and boats, offering a tidy, boltable control point that keeps essential equipment accessible and protected from moisture and vibration.

How does the built-in voltmeter help me on the road or water?

The center voltmeter displays the system voltage at a glance so you can spot battery drain or charging issues before they become a problem. The clear numeric readout is always visible above the USB ports, letting you monitor electrical health while driving or at anchor.

• Real-time voltage readout for 12–24V systems
• Helps detect low battery or alternator faults early
• Mounted centrally for easy viewing from driver or helm

Will the dual USB charger fill my devices quickly?

The panel includes two USB outputs rated at 2.4A each (4.8A combined), supplying near-full charging speed for phones, tablets, GPS units and other USB devices. You can power two devices at once without reducing charge efficiency for most modern gadgets.

• Each port provides up to 2.4A, total 4.8A
• Simultaneous charging for two devices at optimal current
• Works with smartphones, tablets, dashcams and accessories

Is the panel durable and easy to install in my dash?

The housing is constructed from reinforced aluminum with corrosion-resistant pins and comes with mounting screws and a DIY sticker set for labeling. The unit’s waterproof design and secure connectors make it suited to harsh environments while staying compact for flush mounting.

• Strengthened aluminum face for long-term use
• Waterproof construction ideal for marine and off-road use
• Includes screws and sticker labels for a neat installation

How do the night glow stickers and switches improve usability after dark?

Night glow stickers and illuminated switch elements provide low-glare visibility so you can operate switches and locate USB ports without bright cabin lights. This helps maintain situational awareness in low-light driving or boating conditions.

• Glow stickers highlight switch functions at night
• Subtle illumination avoids distracting glare in the cockpit
• Easy to read ports and switches when ambient light is low
