Car Charging Cables

You are standing in a car park with a half-flat power station and a long drive ahead. The car socket is right there, but how much will it really give you? This page helps you decide whether a car cable is a handy top-up or too slow for your station's size.

Aviation plug to cigarette socket

This is the cable for the B210 and B210P, as the retailer lists it. It plugs into the cigarette lighter port at one end and uses an aviation-style connector at the other. It is rated for 12V and 24V at up to 16A, and it is 20 inches long. That short length suits a station sitting on the seat or in the footwell beside the driver. If you own one of those two models, this is the one made for it.

DC7909 to cigarette socket

The DC7909 cable is for smaller stations. The retailer names the B80, EB3A, EB70 and EB70S. These are compact units, so a car socket is a sensible match. A small battery fills more of its capacity from a lift to the shops than a big one ever would. If you camp light and keep a small station for phones, lights and a laptop, this cable is worth keeping in the glovebox.

XT60 to cigarette socket

XT60 is a connector type, not a model name. The retailer gives no compatibility list for this cable, only its name. So check your station's manual or its DC input port before ordering. If your station takes an XT60 plug for DC charging, this cable is the match to look at. If it does not, move on.

XT90 to cigarette socket

The XT90 cable is the same idea with a bigger connector. Again, the retailer lists no models. The plug on your station's input has to match, so look at the port first and the cable second. It is a simple check that saves a return.

MC4 to cigarette socket for larger stations

This one is listed for the AC300, AC500 and EP500PRO. Its stated job is charging the BLUETTI EP500Pro from a car cigarette lighter port. It uses an MC4 connector, the kind often seen on solar inputs. These are big stations. Think about the numbers before you buy: a large battery will take a long time to fill from one car socket. For these models the cable is more of a top-up than a full recharge.

How to choose

• Match the connector. Aviation plug, DC7909, XT60, XT90 and MC4 are not interchangeable. Look at your station's input port.
• Match the model. Where the retailer names models, trust that list. Where it does not, check your manual.
• Check the voltage and current. The aviation cable is listed at 12V or 24V and 16A max. Your car socket and your station both set the limit.
• Think about length. The aviation cable is 20 inches, so plan where the station will sit in the car.
• Size up the job. A small station can fill up well on a drive. A large one will only gain a little. Follow the manual for your station and your vehicle.

Questions people ask

Is a car cable worth it for a big station?

It helps as a top-up on a long drive. It is unlikely to fill a large battery quickly, so pair it with mains or solar if you need a full charge.

Can I use any cable that fits the plug?

Not safely by guesswork. Check the connector and your manual. If the retailer names compatible models, stick to them.

Does the engine need to be running?

Many cars cut socket power when switched off, and some keep it live. Check your vehicle manual. Charging with the engine off can also drain the car battery.

Which cable for a small station?

The DC7909 cable lists the B80, EB3A, EB70 and EB70S. If yours is one of those, start there.
