Description
xOverview
Meet the TIANWIDJEW 2-pack 12V USB outlet panel, a lightweight, surface-mount charger designed for tight dashboards in RVs, boats, and cars. This unit blends three ports with a built-in voltmeter, giving you clean, at-a-glance readings of your battery status as you travel and keep essential devices ready for the road ahead.
Designed for space-conscious installations, it requires only a single wiring hole rather than a large round cutout. This makes it ideal for dashboards with limited space or custom builds where a slim, low-profile charger is preferred, without sacrificing performance.
Why this panel stands out
Real-time voltage awareness, combined with a compact form factor, helps you plan charging on the go. The multi-port setup ensures you can power multiple devices—phones, tablets, navigation gear, or cameras—without juggling adapters.
Key features
- Real-time voltage display to monitor the system while you drive
- Surface-mount design that fits on flat panels with a single wiring hole

- Independent outputs: USB-C PD 3.0 up to 30W per port and USB-A QC 3.0 up to 18W

Installation and durability tips
- Easy surface-mount installation on flat surfaces—drill a small wiring hole, connect black to negative and red to positive, then secure the cover plate
- Combine space-saving design with sturdy materials for long-lasting use in harsh environments
- Regularly inspect the waterproof cover to maintain its protective seal against dust and moisture
Real-world use cases
In an RV or boat, the voltmeter helps you gauge battery status during long trips, while the three-port array keeps essential devices charged for navigation, entertainment, and communication. For daily commutes, the compact form factor ensures a tidy dashboard without crowding switches or gauges.
