DETAILS
Overview
Turn the AC300’s 24V socket into a DC5521 plug
This BLUETTI cable plugs into the 24V cigarette lighter output on the BLUETTI AC300. At the other end is a DC5521 plug, so you can run 24V devices that have a DC5521 input straight from the power station.
BLUETTI suggests it for gear like a CPAP machine, at home during an outage or on the road. Always check that your device runs on 24V before plugging it in.
Fits: BLUETTI AC300 (24V version). BLUETTI makes separate 12V versions of this cable for other units, so contact our team if you have a different model.

Which version is this?
The AC300 24V version
BLUETTI sells this cable in three versions that look the same:
- ✓AC300-24V: this listing, for the AC300’s 24V cigarette lighter output
- ✓B230/B300-12V: for the 12V socket on the B230 or B300 battery
- ✓AC60/AC180-12V: for the 12V socket on the AC60 or AC180
Only the AC300-24V version is sold here. Don’t use it to run 12V-only devices from a 24V socket.
Frequently asked questions
Which BLUETTI model is this for?
The BLUETTI AC300. It converts the AC300’s 24V cigarette lighter output to a DC5521 port.
Is this a car charging cable?
No. It doesn’t charge the power station. It takes power out of the AC300’s cigarette lighter socket and delivers it through a DC5521 plug to your device.
Can I run a CPAP machine with it?
BLUETTI says yes, for 24V devices like a CPAP. Check that your CPAP takes 24V DC with a DC5521 plug. If it’s a 12V model, or you’re not sure, contact our team first.
How long is the cable?
72cm, per BLUETTI.
I have an AC180 or B300. Will this work?
Use the matching 12V version instead. BLUETTI makes AC60/AC180-12V and B230/B300-12V versions. This one is the AC300-24V version.
