Blue Bar 4 Port USB Charger – 2x QC3.0, 2x PD, Volt Meter, On/Off Switch (12V)

4 Port USB Car Charger with Volt Meter

The Blue Bar 4 port USB car charger gives you four charging outlets — 2x USB-A Quick Charge 3.0 and 2x USB-C PD — from a single 12V panel-mount unit. A built-in volt meter lets you keep an eye on your vehicle or battery voltage at a glance, and the on/off switch means you can kill power to the unit without pulling a fuse. A hinged flip cover keeps the ports dust-free when they’re not in use.

Specifications

Shared output — what to know before wiring multiple devices

Ports share output current in pairs, so total available power depends on which ports are in use at the same time:

• Port 1 + Port 2 in use together: combined output is 5V 3.4A (17W total), rather than each port’s individual maximum
• Port 3 + Port 4 in use together: combined output is 5V 3.4A (17W total), rather than each port’s individual maximum
• All 4 ports in use together: total output is capped at 34W (17W + 17W)
• Port 1 + Port 3 in use together: total output up to 54W
• Port 2 + Port 3 in use together: total output up to 60W

What it suits

Suits dash, centre console, canopy or accessory panel installs in 4WDs, utes, caravans, camper trailers and boats where you need multiple fast-charge USB outlets from a single 12V point.

Q: What size hole or panel cut-out do I need?
A: The unit measures 80mm x 45mm x 15mm, with mounting bolt holes 63mm apart for a flush/recessed fit.

Q: Does it have a volt meter?
A: Yes, a volt meter is built into the unit so you can monitor voltage at a glance.

Q: Is there a cover over the ports?
