Overview

A small adapter from NOCO that converts the X-Connect plug on GENIUS and G-series chargers to a standard SAE connector, letting the charger reuse existing SAE cables, pigtails and accessories already wired into a vehicle.

It solves one specific problem: NOCO's newer chargers use a proprietary X-Connect plug, so anything already wired with a standard SAE connector needs this piece to bridge the two. A 20A micro-blade fuse and a watertight housing carry over the same protection as the charger itself. It explicitly does not work with NOCO's Boost or Boost X UltraSafe lithium jump starters.

Converts X-Connect to a standard SAE plug
Built-in 20A micro-blade fuse
Watertight, rugged connector housing
Not compatible with Boost or Boost X jump starters

Who it's for

Fits owners of NOCO G750, G1100, G3500, G7200 or G4 chargers, or a GENIUS1 through GENIUS10 unit, who have SAE-wired connections already installed on a car, motorcycle, ATV or side-by-side. Not for Boost or Boost X jump starter owners, since NOCO excludes those models.

What buyers say

From Amazon customer reviews.

Buyers who already have NOCO GENIUS chargers say it connects cleanly to SAE pigtails and fits curved-style SAE ends on ATVs and side-by-sides such as a Polaris Sportsman or Pro R, while a squared SAE end reportedly won't seat. The recurring complaint is price, since NOCO's proprietary connector leaves no cheaper alternative, and one reviewer noted the polarity is reversed from what they expected on the exposed pin.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

Lets one charger serve multiple SAE-wired vehicles
Built-in replaceable 20A fuse for protection
Watertight housing suited to outdoor storage

What to check first

Costs more than a generic SAE adapter
Polarity placement surprised one long-time reviewer

Performance notes

A replaceable 20A micro-blade fuse protects the circuit and the housing is built watertight for the same outdoor exposure the charger sees. Fitment reports are positive on curved-style SAE female ends used on ATVs and side-by-sides, though a squared SAE end reportedly will not seat against it.

Frequently asked

Questions about the Noco GC009

Does the NOCO GC009 work with the Boost jump starters?

No, NOCO states it is not compatible with Boost or Boost X UltraSafe lithium jump starters.

Which NOCO chargers can use this adapter?

Will this fit any SAE connector on my vehicle?

Reviewers report it seats on curved-style SAE female ends common on ATVs and side-by-sides, but a squared SAE end will not mate with it.
