Review: Easy to Use! - This works great with the NOCO Genius 5 charger. I use this to keep my Porsche battery charged by connecting it to the 12-volt auxiliary port (ensure your car has the "smoking package"). It is so much easier to use than connecting directly to the battery! You just need to roll the window down a bit to let the cable inside. The red light on this connector shows it is working properly. Great design for this little device that saves time connecting to the charger.

## Questions & Answers

**Q: water proof/resistant?**
A: The GC003 is not water proof.

**Q: does the gc003 work with the genius 5**
A: Yes, the GC003 works with the Genius5. Thank you
-Joe Battery Tech

**Q: What size wire and what size fuse ? Thanks**
A: Manufacturer needs to update their product description.   Purchased mine in 10/2020, and it came with a 10A fuse.  Wire gauge seems to be 16AWG.

**Q: Can i give my car a jump using the gb50 boost xl 1500a ultrasafe lithium jump starter from in side my car with this?**
A: No, this accessory is not compatible with the GB50 or any other NOCO Jump Starter, it is designed for select models of our Battery Charger/Maintainers. It is not safe to jump start a vehicle via the 12V auxiliary port in a vehicle, therefore we do not manufacture an accessory that would allow for that.

Great item

### ⭐⭐⭐⭐⭐ The best way to connect and maintain your sxs battery
*by G***B on May 25, 2026*

Such an easy way to keep my sxs battery charged. This addition to my NOCO Charger made the connection a 10 second job. No removing a seat, pulling a floor pan and disconnecting the battery to wire in a secondary cable. Worth every penny.
