The BLUETTI Hub D1 Adds 700W of 12V and 24V DC Outlets to Your Apex 300
The BLUETTI Hub D1 Power Hub is a DC distribution box for the Apex 300 power station and the B300K and B300 expansion batteries. It plugs into the P090D expansion port and gives you up to 700W of DC output through a 50A Anderson RV port, cigarette lighter and DC5521 ports, two USB-C ports and two USB-A ports.
The Apex 300 focuses on high-power AC output, and its USB and 12V ports are provided through the Hub D1. For RVers, van builders, overlanders and boat owners, the Hub D1 replaces a separate battery, fuse block and DC converter setup with one plug-and-play hub that switches between 12V and 24V in the BLUETTI app.
BLUETTI Hub D1 Features
700W of Total DC Output
Run phones, laptops, diesel heaters, water pumps, Starlink, RV refrigerators and more at the same time, up to 700W combined.
12V/50A Anderson RV Port
The Anderson port delivers 12V at 50A or 24V at 25A for high-current DC appliances. BLUETTI rates it for up to 600W of stable output. You can also connect it to your vehicle's fuse box or DC bus bar to supply regulated 12V or 24V power across your rig. The locking connector resists vibration and accidental disconnects on rough roads.
USB-C, USB-A, Cigarette Lighter and DC5521 Ports
Two USB-C ports output up to 100W each for laptops. Two USB-A ports share 15W. The cigarette lighter and DC5521 ports provide 12V/10A or 24V/5A, with up to 120W combined.
Switchable 12V or 24V
Set the RV, cigarette lighter and DC5521 ports to 12V or 24V in the BLUETTI app. The power button glows green for 12V and blue for 24V, so you can confirm the voltage before plugging in.
Flexible Mounting
Clip the Hub D1 onto your Apex 300, screw it to a wall or use adhesive backing to place it where you need DC power. The 4.92 ft input cable gives you room to position it.
App Monitoring and Protection
Over Bluetooth, the app shows real-time voltage, per-port power, total power and error codes. Built-in protection covers over-current, over-voltage, overload, short circuit, over-temperature and input under- or over-voltage.
Real-World Applications
RVs and campers. Power a diesel heater, water pump and 12V fridge directly from your Apex 300.
Van builds. Feed a DC bus bar from the Anderson port instead of wiring a separate house battery.
Boats and overlanding. Keep electronics, lights and Starlink running with a secure locking connection.
How It Compares to Common Alternatives
Versus a DC-DC converter and fuse block. The Hub D1 is plug-and-play, with no wiring, separate fusing or voltage conversion to set up.
Versus running DC loads through an inverter. Powering 12V devices directly avoids inverter losses and leaves AC capacity for larger appliances.
Versus the Hub A1. The Hub A1 connects up to three Apex 300 units in parallel for more AC output. The Hub D1 adds DC outlets.
Is the Hub D1 the Right Fit
-
Compatibility. It works with the Apex 300, B300K and B300 through the P090D port.
-
Power sharing. The cigarette lighter and DC5521 ports share 120W, and the USB-A ports share 15W.
-
Battery charging. The cigarette lighter port cannot be used to charge lead-acid batteries.
-
Environment. Keep it clean, dry and ventilated. It operates from -4°F to 113°F.
This may be a good fit if
- You own an Apex 300, B300K or B300
- You need 12V or 24V power for RV or marine appliances
- You want USB-C laptop charging from your Apex 300
Common Questions
How Do I Switch Between 12V and 24V?
Turn off the Hub D1, then change the output voltage in the BLUETTI app. Always confirm the indicator color before connecting devices.
What Happens if I Exceed 700W?
The Hub D1 turns off the cigarette lighter/DC5521, USB-A and USB-C outputs in sequence until the load is back within its limit.
Can I Use It With a B300K Battery Alone?
Yes. Connect it to the B300K or B300 expansion port and monitor it in the app over Bluetooth.
