Everything about the DC Cable Fuse
Why your DC cable has a fuse
Vehicle electrical systems spike — engine starts, jump starts, alternator surges. The inline fuse in your Inogen DC cable sacrifices itself to protect the concentrator’s electronics. If your unit suddenly won’t charge in the car but works fine on AC, this fuse is the first thing to check.
A 30-second fix
Unscrew the cap at the tip of the DC plug, drop in the new fuse, screw it back — done. At this price, seasoned travelers keep a spare in the glovebox permanently.

Frequently asked questions
How do I know the fuse is blown?
Your concentrator charges normally from a wall outlet but shows no external power when plugged into the car. Swap the fuse first — it resolves the majority of DC charging failures.
