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.

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.

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?
