      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

USB power jacks

Recommended Posts

Our boat has plenty of the standard 12v automobile style power plugs. But most them are occupied with some USB converter... Just more bits of kit to keep track of. So, does anyone make a panel/wall mountable USB power jack? Ideally it would supply 2 amps of +5V. It would replace the jack below with a USB port (and a 12v-5v converter).

I think he's trying to consolidate his USB power outlets / ports into one outlet and free up the other 12V outlets because he currently has only one USB / 12v outlet. So that link will give him multiple charging points at one 12v outlet.

 

I have a panel mounted 4port USB hub on my boat, but it is a hub, there is no 12v > 5v conversion. Worst case he could take one of the devices on that link, hack the power side to wire into his 12v system and then panel mount it. But why tear up some good joinery just to panel mount something that will be useless in 5-10 years when the next power source comes along?

 

There were 21,000+ hits on that search, just at Amazon. I'm pretty confident there is a solution to every 12v / USB need.

 

Vous comprenez?

You can get bulkhead mount USB connectors from someone like Digikey and find a 12 volt to 5 volt power supply to power them all. You can get any current you want that way.

 

They also make USB power cigarette plugs that are flush and maybe just gluing these into your existing outlets would be the easiest.

isn't 2A allot to draw from USB

 

are the cables up to that load ??

 

most things would fry if plugged into a USB packing 2A

 

what kind of device are you trying to power

 

 

You can get whatever Cig/lighter plug mount and jam one of these to convert it to what they don't make

 

But it's 1/4 of what you say you want it to put out

 

2A is a Bunch !

 

 

$8.00

Juice your gadgets without losing a cup holder

e24a_tiny_usb_car_power_adapter_inhand_embed.jpgOne of the best things about technology is watching new devices shrink in size as time goes on. Remember how big cell phones were back in their infancy? They were practically bricks and could only barely make phone calls. Now we have phones that are handheld computers and cameras, and handheld computers and cameras that occasionally make phone calls when the stars align. *cough* ANYHOO, one such device that is finally shrinking to a manageable size is the car power adapter.

 

Say goodbye to the clunky chunks of plastic and metal that blocked the driver's side cup holder! The Tiny USB Car Power Adapter fits snugly into the cigarette lighter, jutting out just enough for you to be able to pull it out. But you won't want to do that! You'll be thrilled to have a charger that you can use to power up your phone or phone-like device, mp3 player, or other electronic wonders. You'll be even more thrilled that you can still fit your giant +32oz Vessel of Caffeine into your cup holder for those long drives. Perfection.

Hot topic. Oui, my Google-fu is pretty good. But the S/N ratio is very high on these keywords.

 

My plan is to exactly replace the chain of 12v plug and adapter with one clean install. Maybe 2 USB connectors on a 1 sqr inch panel. Dawoody remember we are talking 2 Amps of 5 Volt power,not twelve. And thats the standard output for ipad charging. Some of the plugs linked to are a step in the right direction. but still need a 12-5 volt converter. I can wire that up if need be, but would like an all in one solution.

 

At any given time we got two iphones, a ipad, and a HeroHD all wanting USB-based power. This could be a small block of USB plugs, and not a line a huge 12v auto plugs with adapters plugged into each. My Davis Ultralight is the only actual device I have that wants that cig plag.

I think the panel mount and 12v are an oxymoron from the manufacturer's standpoint. They assume if you've got 12v, you've got a cig lighter.

 

This product will give you the four outlets for your four devices, and you'll have have the cig lighter: http://www.amazon.co...31321841&sr=1-3

 

That device you link to is pretty close for a short term fix.

 

But I think you are wrong about the 12V and USB power aspect. Try and find a new car without a USB jack in it. They know that the vast majority of mobile devices now are USB powered. Now thats not to say that there is not a place for 12V cig lighters, but I think you can expect to see USB power plugins (both as OE and AM) for marine use very quickly. Those little plugs are a total stop-gap solution.

I completely agree that the cig lighter outlets are a crappy 12v outlet. I've had mil-spec 12v outlets on my last two boats for the deck outlets, but the cig lighter outlets are still the most practical below decks.

 

My point about cutting up your joinery is that 10 years ago nobody used USB for power, and neither will they 10 years from now. USB as a data connection is going to be a "legacy" connection within 3-4 years, replaced by wireless or faster wired connections, just like 9 pin serial ports had their day and are now gone. We're already using wireless to transfer data to the i-devices, who needs a all the serial connection stuff when all you want is a little juice? In another 4-5 years we'll see a different way to charge all of these device (most of which have a life cycle of only 3-4 years). So why cut up your joinery today for something that won't last as long as your boat? If you've got a replaceable panel that's expendable (I have formica at my nav station) then no worries, cut away and replace the whole panel in a few years.

Interesting points. I agree that the power and data interconnects between devices is a moving target. But I think USB as a connection will be around for a while. 5 volts is preferred voltage for most devices, and because the automotive market has embraced it, it basically grants it at least a 10 year lifespan... as all automotive OEMs and T1 suppliers assume that. Good discussion. And you are right, I'm never shy when it come to cutting holes in boats!

For all its faults, USB is going to be around for a long time as both connection and power port. All cell phones are going to it as a standard. There are still serial ports around too, and how many years have we had the cigarette lighter? Nobody even uses it for that anymore!

I think if i understand it right, he's just looking to charge a ton of usb items off one port not the 6 he's using now. Find a usb hub with an external power connector. Then you'll have 7 or so usb ports to charge from.

 

Canadian tire carries a number of similar solutions. Couldnt tell you the brand off the toP of my head. And being in minnesota, the store does fuck all too.

sounds like a good solution but a lot of those USB hubs will not put out enough power to change a phone for example. At least not the ones I bought. Very frustrating btw.

That's not a bad temporary solution. You would have to find one that came with a 120AC to 12DC converter and cut off the converter and just use the plug. As Alan notes the question of current to each devices comes up.

Most "smart" phones need a minimum of 1 amp @ 5v, with tablets needing 2 amps @ 5v. Not too much commercially available, other than the oem adapters.

 

Looks like the TAPP mentioned above will do the 1 amp stuff.

There are some 2A USB car-charger adaptors. Here's one:

Amazon.com

 

The total available current is 2A, so you can use one jack for a high-current load, and the other for a low-current one. I've not used this particular device, but have used similar ones. Yes, the cigarette lighter format is a poor one, but sometimes you have to deal with the real world. Or, go to a lot of trouble.

That is good for iPads, but Apple uses a circuit that is liable to trip up the unwary...I've got a Touchpad and the Apple chargers would not charge it. Fortunately, a Scottish fellow took one apart and discovered that by soldering in a resistor between two of the lines that led to the jack, it would now charge the Touchpad! Sold several of the devices to Touchpad aficionados.

hrm, i believe USB hubs are limited to 500ma. 2A at 5 volts! holy!

To get the iPad to charge effectively, you need 2.1A. It will charge at lower amperage, but usually only while sleeping and the charging icon won't show up.

We use a consumer-grade 6 port powered USB hub in the navstation. It has its own, hard-wired 12volt feed. It is usually full (!), but it will charge up devices OK. Sometimes see strangeness with iDevices (as mentioned above). Not sure on the amp output.

this is what i was talking about CT having. It's almost the same except it is hard wired not a plug in as this one is.

 

 

 

 

http://www.ebay.com/...=item4ab4a4ad2f

 

combine that with 2 of the cigarette usb plugs and now you've got 6! they have a sticky pad on the underside of it.

 

 

 

I think they're $15 Cdn if you want one pm me and i can send it to you.

 

 

edit: just stumbled upon this

if you can find a 12v to 5 converter, you should be good to go

Its probably not exactly what you're looking for but if you need a new sound system then you could kill two birds with one stone as I believe you can charge off it. I dunno, seems like a cool product.

 

http://leftcoast.biz/iWeb/Left_Coast/Simple_stereo.html

 

Yes, you can charge off it. I picked one up last fall. Really sweet, no moving parts. I keep several of the iPod-to-USB cables around 'cause they are always getting lost. monoprice has them for ~$5.00. m/m 3.5mm cables too.

You can pick up a radio with ipod integration (that charges it too) and a wired remote for the cockpit for under $100 online. I can't see spending that much for a unitasker.

Our boat has plenty of the standard 12v automobile style power plugs. But most them are occupied with some USB converter... Just more bits of kit to keep track of. So, does anyone make a panel/wall mountable USB power jack? Ideally it would supply 2 amps of +5V. It would replace the jack below with a USB port (and a 12v-5v converter).

Your panel cutout may not fit but this is what you want if you want one USB only. Two types available, one USB only (APUSBE) or one USB and 3.5mm MP3 input (APUSBE). The 12V/5V conversion is done onboard. It is automotive and not marine, though if you are using a USB hub, that may not be marine or waterproof either. Can't tell you panel cutout size....

I like the jensen MS30 and will probably install it in my boat: http://www.rocktheboataudio.com/html/62087.html

Don't know about the sound quality, but it's light, small and has all the features that I want.

Anyone got any experience with it?
