Great Product
This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

Plugs Right In To SAE Connectors
I’ve always made my own adapters to go between battery chargers and my various vehicles and equipment with SAE style connectors. This adapter saves time and hassle and works perfectly.

Should be included.
Ctek makes a great charger. Wish they’d include this with the product. Their proprietary plugs are annoying.

Works well for both battery charging and for a quick check of battery health
I install SAE quick disconnects on all my car and motorcycle batteries. This allows for quick and easy charging. I use this CTEK comfort indicator not only when I am charging with my CTEK battery charger but also as a quick check of battery condition. Just plug this comfort indicator into the SAE disconnect. Green light illuminated means your battery is charged over 90%. Yellow light means the battery is charged between 40% and 90%. Red light means the battery is charged less than 40%. Couldn't be easier.

Defective Product
Product defective, flashes yellow or red on full charge on a new battery that works as it should. Missed the return window, stuck with a useless product. Contacted Ctek, they responded promptly and sent a new replacement. I give full credit to Ctek with supporting its products, regardless of who the vendor was.
