      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

USB power jacks

41 posts in this topic

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).

Has reading comprehension reached French Polynesia? He's trying to get rid of exactly what you just linked,

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 !

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:

 

41LlYgZ%2BrjL._SL500_AA300_.jpg

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.

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.

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....

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

The one linked above has a 5v 2A output, but is that per port or in total? IMO it's most likely 1A per port...

 

I've found this myself, though it's only 5v 1A...
