## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazing Quality Product
*by A***R on January 26, 2024*

Works perfect to place my vehicle on the battery maintainer for the season

### ⭐⭐⭐⭐⭐ Perfect.
*by H***F on October 30, 2014*

Just what I wanted for a cig adapter. There is a sticker on the tube it comes with but if your not sure, the Long end plastic covering the metal (female) of the Sae is (+) and the exposed side you see metal (male) is the (-).I got this with the mind of using a charge controller and small solar panel while its in my car to help keep the battery charged this winter so I don't have a dead battery. I don't drive my car much specially in the winter so I need to keep the battery healthy.

### ⭐⭐⭐⭐ Not just for cars - I use it with a portable jumpstarter
*by I***C on September 17, 2014*

I use this with my either my Optimate 6 or my Optimate 2 to make it easy to charge my Stanley jump-starter pack with air compressor.My jumpstarter has it's own internal charger, but I prefer to know the battery is getting an even better and smarter charge than what comes with the jumper, and when the Optimate 2 isn't doing other chores, I'll use it with this adapter for long term maintenance on the jumpstarter.
