UpBright Car 12V DC Adapter Compatible with Inogen One G3 G4 G5 DC Power Cable Model BA-306 BA-301 Auto Vehicle Boat RV Camper Cigarette Lighter Plug Power Supply Cord Cable Battery Charger Mains PSU

I have used 12VDC car cords daily for years and have tried substitutes, mostly because of the high replacement cost of original equipment for use with the Inogen, G2, G3, G4 and the Oxygo equivalent units - ie; prices ranging from $45 to $80 US. The substitutes have failed or didn't work - but this one does work in cars but will not plugged into other shortened female receptor sockets found in battery packs and other accessory equipment (the male plug is slightly too long as compared with the inogen unit and will not make ground tab contact). Key features are the unusual large metal button (see photo) on the male plug, good fit on the female and adequate wire gauge ...18 gauge or 16 gauge required and decent insulated wire quality. The original equipment is slightly better, a more versatile male plug that seems to fit almost all receptors besides autos, sturdier build quality and has a 5 foot cord vs a 3 foot cord that this unit has - its just hard to justify the very high cost. Recommended for use in autos.

This item works as advertised. My only issue is it might be a bit less heavy duty as the connectors and wire get a little warm. They do not get dangerously hot, but for the price I'd like to see one gauge larger wire and better quality connectors.

I was VERY Leary of how thin the wires were but turns out they are about the same gauge as original just without a thick covering. I used it for 2 hours didn’t blow my fuse and didn’t heat up. It was warm to the touch at the outlet but not hot. I’ve been using it for about three weeks and it’s fine so far!

Gets very hot during use. Wire gauge obviously not big enough. Also, plug gets very hot. You get what you pay for.

Was disappointed with the quality considering the cost of the cord. Okay for an occasional backup but I wouldn’t use it as my main cord.
