Quality every time.

There are cheaper alternatives out there, but I know the quality I am getting when I buy OptiMATE. I know it will work. I'm willing to pay a premium for that.
I needed to divide the power in my kayak so I could add the ability to charge my phone. All of the connections are SAE, so this was the logical choice.
I have never been, and will never be, compensated for a review of a product. This is my opinion, and lots of it.

This Y adapter is very flexible and has a good feel to it

I purchased this to complete a simpler on-shore charging system for my boat, the kit will work for any situation where you need to periodically charge or maintain 12volt batteries.
This Y adapter is very flexible and has a good feel to it. The connections are tight and secure. Each connector has a provided boot to provide some protection to the connection. The splitter worked great for my purposes and is now allowing me to charge two batteries with a single charger.
The charging solution I am using this with includes two different charging sources, a Suaoki 60Watt solar and a Noco Genius G3500 Smart Charger. Both are great and provide a similar amount of power to the batteries. The solar charger does not work so well at night though, and the wall charger does not work when out camping on the boat.

Using the Suaoki solar charger requires the using of a solar charge controller for safety. The Suaoki can be directly connected to the battery, but then the voltage must be monitored as it can overcharge your batteries and lead to premature failure or worse. I am using the Instapark PWM charge controller for this task and it is a perfect match to the system.

The NOCO Genius uses properietary connectors and while it comes with a few different options, none of them made it compatible with my requirements. I ordered the NOCO to SAE adapter and now it connects to a standard SAE plug and works well, interchangably with the Solar charger.
http://amzn.to/2wrOxl0
In order to add flexibility in placing the solar panel or connecting the NOCO charger, I added an SAE extension. Essentially this is a 12V extension cord. Any SAE to SAE cable will work provided it has sufficient gauge(AWG). For a 15ft length this should be at least 12AWG with 10AWG or even 8AWG being better. For a 5ft length 16AWG or 14AWG will be acceptable, of course 12,10 or 8 still better. Anything smaller less than those maxiums will degrade the charging capacity as it will cause an significant voltage drop. Here are a couple alternatives that look good.

I used two ring terminal to SAE adapters, one for each battery, as the aligator clamps were problematic and not particularly reliable. The aligator clamps meant that I had to climb into the compartment where the batteries are stored in the boat and almost always insured a good bump on the head. Sometimes I would come back the next morning to find one had fallen off. Using ring terminals insures a secure connection to the battery and allows me to quickly connect/disconnect without bumping my head. I used the Tetra-Teknica MotoBasics 16 gauge 2 feet 10A fused 2 pack for my solution.

In order to charge the two batteries in parallel, I needed to add an SAE Y adapter. The OptiMate Y-splitter worked nicely. I disconnect it when not charging as I do not want power accidentally pulled accross this connection if the boat is using a single battery. I am looking for a solution, a diode that will allow me to keep this connected permanently without that risk.

The system is working well and keeping my batteries topped off between outings without a problem.

Check fuses first
notfastenuf✓ Verified Purchase•December 14, 2016
Great cables. Had an issue with my charger but it turned out that one of the in line fuses that was bad. Strange, it wasn't blown but it measured a resistance when I checked with my multimeter. Not sure if that was related to my charger frying itself or not. Replaced fuse and cables are great again.
No good
Kindle Customer✓ Verified Purchase•November 7, 2016
Well after I installed this on my motorcycle I thought my usb port tgat i use to charge my phone shorted out and caused the fuse to blow 10amp fuse. Then I noticed my other accessory wasn't working has a 4 amp pull max so upon checking out the Y splitter I realized the wiring in it was no good took that off and put things back how they were and now both accessories work again . I was trying to eliminate some of the wires under my seat well scratch that idea. I'm not worried about contacting the seller because I'm just going to cut my loss and move on.
Great stuff

Very good build quality. I use Optimate for all my SAE stuff on my bike. I put this on after the Optimate batter tender lead. I really like this one since it has fuses. I run an SAE extender from here up to the bars for USB charging ports. I would put a small rated fuse in like 2.5 or 5 if using for that purpose. Protect your electronics better.
