Posted: Thu Oct 10, 2013 9:22 am Post subject: iPad charger?

I've been looking for an accessory adapter that will charge an iPad (while in use). All the adapters I've found so far either don't put out enough power to charge the iPad or, if they can, get really hot and eventually fail. 



Has anyone found a charging adapter that will work (on 14v and 28v aircraft)?



I was also thinking of building one with a panel mount USB port. But so far, every circuit I've found has... issues.     Does anyone have a suggestion for such a circuit?

I picked up a few cigarette lighter adapters from Dealxtreme that were supposed to be able to provide ipad current. Some couldn't, and one made my car radio unusable whenever it was plugged in. Sorry to not be able to provide any more help, other than to say that you may have mixed results with the seemingly easy and cheap import options.

Dan,



I mentioned this once in passing and have avoided further mention for fear of sounding like a marketing wonk, but since you're interested...



I've been developing a product to do exactly what you need.  As it's shaping up, it should be a board about 1.25 x 2.5 inches with a rugged dual-USB receptacle at one end and a connector for ship's power at the other.  It will comfortably charge two iPads -- or pretty much any other USB-charged device -- at once, and will include noise filtering and automatic shutoff in the event of charging system failure.  The USB receptacle is a panel-mount unit that uses two #4-40 screws.  It can be mounted in a custom cutout in the panel, or I plan to offer sub-panels to fit standard instrument cutouts.  You could of course also fabricate your own mounting solution.



Stay tuned; I'm pushing hard to have it ready ASAP.



Eric

I use a 12 volt cigarette plug from Radio Shack that puts out the required amps for 2 iDevices.  I haven’t looked for a 28V charger. 

You do have to specify that is for an iDevice to get one with the proper power output.

Eric -

I would certainly like to have a couple of them for my project. Big 

problem on my trip to Alaska.  We had purchased 3 or 4 expensive USB 

recharging receptacles and converters.  By the time we got to Calgary, 

every one of them had crapped out, two of them wouldn't even work on 

plugging them in, although they all worked when we checked them prior to 

the trip.  We got a ride to a Radio Shack, and bought a couple more, and 

those managed to work until we got to Anchorage.  We were flying with 2 

iPads for redundance, thank goodness, plus had the weather on the 

Stratus ADS-B, and an iPhone for a back up panel.  Sure enough, we lost 

a vacuum pump about an hour out of Ft. Nelson, Canada, and the iPhone 

app made it a non event, even with weather closing in.  Had to make a 

couple of more legs before we could find a replacement vacuum pump.

That experience has convinced me to include USB plugs plan for extra 

electrical taps for whatever hand held equipment is available when I get 

it completed.  Plus, I just hate having all the cords running all over 

the cockpit.

Marvin,

Thanks for this story!  That's *exactly* why I'm designing this product.  The market is flush with USB chargers of every size, brand, color and price.  Sadly, apart from a few OEM products, they seem to share one trait in common: poor design, parts quality and manufacturing.

It's obvious that portable touch-screen devices are the way forward for many pilots, and USB has become ubiquitous for charging them.  Now we need a reliable charger.

Hi Eric,



Is it a "no-noise" circuit or switched w/minimal noise ?

BTW I've been very pleased with the 24V to 19 V (for Lenovo tablet) no noise charger/PS you made for me.

And you need to design so that the unit can be hard wired into the panel, not just portable.

I bought one from Best Buy about 3 years ago - I use it in my truck for my

iPhone most of the time; but it has had no problem on long trips keeping

the iPad going.  It even has a USB adapter on the top of the cigarette

plug that I have used simultaneously to charge another device.  Works like

a charm.

Ooops! Sorry, Eric, I was to fast, obviously not paying attention as to who the originator was -

I was referring to Eric Jones (Perihelion Design) in my earlier post.

Rumen

P.S. You are right, I've been burned twice with these "nice, professionally looking" 5 V devices on ebay.

Now, I am testing this one:     tinyurl.com/l7h235y

Presume it's a switcher, but no noticeable noise; hope it doesn't burn out (and my tablet).

Would appreciate feedback from others, if anyone else is using it.

You got lucky!  I've got one that I use in my truck too that has been a good one.  But the ones we took to Alaska were junk.....and 3 of them were expensive, which we bought under the premise that "you get what you pay for".  Not so!  We took all of them apart in the motel to see if we could fix them....just junk.  I've got one from my old Noki smart phone that is really good, and two Apple units that are in constant use.

That looks exactly like the most expensive one we had on the trip, but ours did not have the big lable.  Lasted only the first day in the airplane.  I think we paid $30 or $40 for it in an electronic shop at home.

What voltage did you use them/it on?

I might be wrong, but it seems that most of the products advertised for 12-24 V can't really handle well the 24-28V bus. I had one toasted the instant it was plugged in, free running, no load.

Hi Eric,

 I have been thinking about how to do this too.  The panel mount would  be ideal.  When  you get it ready to test or sell, sign me up.

Marvin,

Thanks for this story!     That's *exactly* why I'm designing this product.  The market is flush    with USB chargers of every size, brand, color and price.  Sadly, apart    from a few OEM products, they seem to share one trait in common: poor design,    parts quality and manufacturing.

It's obvious that portable    touch-screen devices are the way forward for many pilots, and USB has become    ubiquitous for charging them.  Now we need a reliable    charger.

 Eric -

 I would certainly like to have a couple of them for my project. Big    problem on my trip to Alaska.  We had purchased 3 or 4 expensive USB    recharging receptacles and converters.  By the time we got to Calgary,    every one of them had crapped out, two of them wouldn't even work on plugging    them in, although they all worked when we checked them prior to the    trip.  We got a ride to a Radio Shack, and bought a couple more, and    those managed to work until we got to Anchorage.  We were flying with 2    iPads for redundance, thank goodness, plus had the weather on the Stratus    ADS-B, and an iPhone for a back up panel.  Sure enough, we lost a vacuum    pump about an hour out of Ft. Nelson, Canada, and the iPhone app made it a non    event, even with weather closing in.  Had to make a couple of more legs    before we could find a replacement vacuum pump.

 That    experience has convinced me to include USB plugs plan for extra electrical    taps for whatever hand held equipment is available when I get it    completed.  Plus, I just hate having all the cords running all over the    cockpit.

12 Volt - two of the cheaper ones did the same thing, even though we had tested them at home.  Alternator at the time was putting out 13.8 volts according to the volt meter.

 What voltage did you use them/it on?

 I might be wrong, but it seems that most of the products advertised for 12-24 V can't really handle well the 24-28V bus. I had one toasted the instant it was plugged in, free running, no load.

 That looks exactly like the most expensive one we had on the trip, but ours did not have the big lable.  Lasted only the first day in the airplane.  I think we paid $30 or $40 for it in an electronic shop at home.

Rumen:  No worries.  I think I've seen three Erics on the List!  I haven't seen the charger you've got, but I'm sure it's a switcher.  They all are.  Getting enough current at 5V to rapid-charge an iPad through a linear regulator fed with 14V would make an 18-watt heater!



Marvin:  Panel mounted and hard wired is exactly my plan.  Nice, neat installation and zero hassle during use.



Michael and Earl:  Thanks for your interest; I'll add you to my contact list.



Cheers,



Eric

Add me to the list - I already have the panel spot and fuse slot identified.



Is there an 'easy' way to determine externally whether a given cheapo or 

high price cig plug usb charger is the switcher/linear regulator type or 

the type that has some chance of working for awhile?  'Easy' being 

defined as with a multi-meter or perhaps even a quick peek inside.



I've been thru a number myself.  I have one that seems to work on my 

other non-iPad devices but I've been saving it for an emergency iPad charge.



In the end, I was so ashamed of having cigarette plug in my '10 that I 

hid it behind a back seat cushion.  Given the variety of devices needing 

a USB charge, I can't wait to put something up front.  I figure by the 

time I get it, the USB standard will change but that's life.

Eric, as you can see, there's quite a bit of interest in your iPad charger. Not sure what switching IC you will use, but I woild like to see an automotive charger that provides two USB outputs.  The ones I've used are flakier than hell, and I'm starting a 6,000 mile USA round trip in December.  I want to take my Garmin 496 so I can capture breadcrumb trails to send home to mama. That will require one 12 cigarette socket and two USB outputs.  Anyone know of something reliable that exists today?
