BLUETTI DC Hub for Charger 2
This DC Hub plugs into BLUETTI Charger 2 and gives you Anderson, cigarette lighter, DC5521, USB-C and USB-A outlets, up to 600W in total.
Flick the RV (Anderson), lighter and DC5521 outputs between 12V and 24V to suit your gear. Monitor voltage and power over Bluetooth in the BLUETTI app.
BLUETTI lists one compatible model: BLUETTI Charger 2. The hub runs from Charger 2, not from a power station directly. It is not the Hub D1 (that hub is for the Apex 300).

Outputs
Bluetti says the hub powers RV appliances, diesel heaters, laptops and electronics.


Engine off?
With only the engine and solar feeding Charger 2, the hub depends on them. Connect a BLUETTI battery (such as a B300K) to Charger 2’s BAT port and the DC Hub keeps running with the engine off.
The 600W is shared across all the hub’s ports.
Which hub?
BLUETTI makes two similar-looking hubs. This one is for Charger 2. Hub D1 is for the Apex 300 (and B300K/B500K) and does not connect directly to Charger 2.

Yes, if a BLUETTI battery pack is connected to Charger 2’s BAT port. Without one, it relies on the alternator and solar.
