I am looking for a way to charge my cell phone via USB. If I cut off the plugs and put on terminals and connected directly to my boats battery would this work?

Way too much trouble.....

I have a marine 12v outlet that I just put 2 wires on with alligator clips, you can pick
up a plug in usb charger at a dollar store and plug into that and charge.

I use mine if needed while traveling on the bikes and it is portable.

Another idea we use is one of those little jump start deals about the size of a cell phone.
I paid $39 for mine and it will charge up 2 phones, has a flashlight if needed, and of course
will jump the bike

And if you don't have a couple of these 'cigarette lighter outlets' get some. Lots of 12v stuff easily plugs into them. The device in the OP seems unreasonably complicated and has one specific function, whereas a 12v cigarette lighter outlet can be more versatile.

Thanks, I don't have a cigarette lighter outlet. My electronics needs are minimal. I do plan on installing a GPS/Fishfinder but that would be wired directly. The only reason I am considering this USB option is I bought a bluetooth speaker that I plan on using with my phone. I want to have the ability to charge the phone as needed.

I agree that a cigarette lighter gives you more options, but I'm just not sure there are too many options I haven't considered for what my needs are. (Although I am open to suggestions!)

I like the fact that I could just hook up some alligator clips and have a USB charger available without any additional installation needs.

I guess my primary question is whether this product is appropriate for cutting off the plugs, attaching terminals or alligator clips and hooking it up to my 12v batteries.

Btw, it's a 17' CC boat with outboard.

This sounds like a good option too.

A USB charger is a transformer with an output of about 5 volts. Hooking a 12 volt output direct to your phone is not a good idea.

If you can find the other half of the plug from the manufacture...

...and wire that directly to the battery, it would be a nice enough set up. When you want it, just plug it into the plug/wires already hooked to the battery.

But yes... you could cut the plug off, add alligator clips, and use it that way.

That is an Anderson Power Pole connector, keep it and wire in a mate.

If anything, check to make sure that a 3A charge won't cause a problem for your phone's battery.

Cigarette lighter socket is a good simple way to go. Install a double and you can charge your phone and run your plotter. KISS

I installed 3 cigarette lighter outlets in my boat. With them I can:
Charge my phone
Run my iPad as a gps/chartplotter
Charge my Bluetooth speaker
plug in a portable fan
Use a gazillion candlepower spotlight
And, I suppose, I could light a smoke if I so desired.

Correct. Plus its a PIA.

Drill a hole.

Install this receptacle: $16

Yup.

The world of electronic gizmos runs on 5.5 vdc, any more.

Gotta have that 12-5.5 vdc transformer, or toast your expensive gadget.

If I tried to use alligator clips sooner or later I would get reverse polarity and ruin the device.

My vote is for cigarette lighter sockets an adapter like this. I have at least 4 of these.

This sort of thing is available cheap—

You can plug in any 12 volt device: light, radio, power tool, etc.

Buy one of these and you've got a USB socket for charging:

Besides simplicity and low cost, I like the multi-use aspect.

No fuse, sparky alligator clips. What could go wrong? See post #12

Basic idea of what I made, but with a marine outlet....... And a fuse.

It's also worth noting, that ABYC specifies that the only device(s) hotwired to the battery(ies) should be the bilge pump(s).

Also, also...Jefe's boat is gasoline powered and so any electrical device should be ignition protected, per ABYC ( and common sense).

Well, it's an outboard, so it's not as big a deal as a gas powered inboard.

ll, it's an outboard, so it's not as big a deal as a gas powered inboard.

That's what the regs say. But I disagree with the regs. It's the fuel tank, gas fumes, and battery fumes that might ignite. An outboard moves a big source of ignition--the engine--out from machinery spaces. An outboard isn't likely to ignite leaking fuel or trapped vapor the way an inboard might. But other ignition sources, such as have been discussed here might. I say, safety still needs to be adhered to in those spaces.

For full regulations, check the Code of Federal Regulations (33 CFR 183.410. (https://www.uscgboating.org/regulations/assets/builders-handbook/ELECTRICAL.pdf)) or ABYC E-11.4.15 and E-11.5.3.

The whole gas/ diesel safety issue is a bit of a conundrum. Yes: gasoline, or its vapor, will ignite much easier than diesel. Scientific fact.

But, there is something on the order of 60 times the number of gasoline-powered boats compared to diesel powered boats. Yet, boat explosions are rare as fur on fish.( Although it only need happen once to be bad!!)

The same 12 volt socket is available with loop terminals that can be put on the battery with no risk of sparks.

What a bunch of pusillanimous pettifoggers you guys are.

Yes...feeding +12 VDC to a lithium-ion battery that is expecting +5 VDC is likely to lead to


https://m.youtube.com/watch?v=5J96ywv7yAM

Lithium-ion batteries have energy densities approaching that of dynamite.

But there's more to USB charging than a transformer putting out +5 volts DC on pin 1. Pins 2 and 3 are data lines. Pin 4 is ground. First thing that happens when you plug it in is a negotiation regarding power. How much (at least 100mA is required, but if the device desires more, it has to ask for it.) There is also a negotiation about the direction of power delivery (which end of the connection is providing it).
