Folks,
Of the zillions of USB power supplies available, do you have any thoughts about what works well in an AB airplane? I want one 2A port for an iPad and a couple of 1A ports for other stuff.
Thanks,

Art,
I am in the process of installing one of these. http://www.appareo.com/stratus-power/ This thing is supposed to be FAA certified and TSO’d. It’s not cheep but if it works as advertised I’ll be a happy camper. I got tired of replacing those cigarette lighter units that worked sometimes and didn’t work other times.

Once I get it installed and get my ADS-B 2020 gizmo installed I’ll report on them.

If you want plug&play, talk to these guys:https://www.steinair.com/?search_category=&s=usb+power&search_posttype=product

They have a stellar rep with the RV-x crowd; they've built panels for a lot of RVs. They supposedly are taking an off the shelf USB jack and modifying it to ensure that it's quiet and reliable.

Thank you! I don't know why I didn't think of checking SteinAir. That looks perfect.

I have fitted the two port version of this in my Europa Aircraft. I have not used it in flight yet ( only started test flying recently), but it has had some very good reviews in the UK

Wow! I should hope they got good reviews... Based on today's exchange
rate, the Charge 4 is a bit over $257 (plus shipping)! You could
purchase eight of the SteinAir version for that!

Another one worthy of consideration if you need/prefer a "horizontal"
charger would be the Belite Aircraft USB Dual 2.4 amp charger, which
sells for $75. It can be seen at
http://www.beliteaircraftstore.com/usb-dual-2-4-amp-charger/ (The
single-port version can also be ordered through Aircraft Spruce, though
it's a bit more expensive for some reason...)

Good lord, people!! You can pick these power regulators up every day that plug into a cigarette lighter for $5! They are all an LM357. I have a junk drawer full of them. And, the cigarette lighter jack is good for older equipment that is configured for it. Why would anyone ever pay over $10 for one?

Why is aviation expensive? Because, people are will to pay for it?

While I agree that $hundreds$ is just silly, there can be issues with cheaper (and even some less cheap) adapters. Some generate quite a bit of audio frequency and RF 'noise' that gets injected and/or transmitted into intercoms, radios, nav systems, etc. SteinAir claims to modify the ones they sell to ensure that there's no noise.

Another potential issue is that a lot of tablets, especially the the self focused ones (i etc), don't play well with many aftermarket chargers. The tablet needs to hear from the charger to know it's ok to draw the full 2+ amps, or it won't quick charge; sometimes that means it will discharge faster than it will accept charge current.

Slightly more than $10 (I paid $12 without the cable), but these work
great to charge both Android and iPad devices at the same time, dual 2.4
amp ports (4.8 amps total), with no spurious RF emissions that I've been
able to notice.

$20 including a cable is still a pretty good deal:

Slightly cheaper on Ebay, search there for "scosche usbc242m"

This attitude makes it almost impossible to make a good quality one for a reasonable price for the OBAM market.
You’re competing with junky $10 units that don’t even deliver their advertised power rating— and people think they can just build their own with a 7805.....
Short answer: you can, but it will be useless, and if it does somehow work it will dissipate more power in heat than it delivers to the device.
These power supplies are deceptively complicated between the efficiency, noise, and interface requirements for the different devices.
Don’t be so quick to pan the good ones, because at least in this case, if you want a ‘good’ one you’re probably going to have to pay for it.

Wow! - I never expected to stir up such a hornet's nest Rolling Eyes Very Happy

I chose the Charge2 for two reasons:

1. As has been mentioned here, I had experience of the lousy performance of cheap cigarette lighter adaptors in my C182
2. Having spent an age (and a fortune) designing my "perfect" Control Panel for my new homebuild, I wanted something plumbed in that was aesthetically pleasing, and harmonised with the other instruments (Dynon).

The original requirement was for something to power my PilotAware in the 182, and followed a lot of discussion on the PAW Forum. I understand from there that for those who had no option but to follow the cigarette lighter approach, (or wanted a cheaper option), one of the Anker adaptors fitted the bill.

You are also competing with good ~$10 units that deliver the power,
don't overheat, and aren't causing radio interference, but you are
correct that there are a lot of junk ones out there, which is why I and
others have offered feedback on units we've tried.

If it doesn't work out, you have a $10 (or $12 in my case) unit you can
use in the car, or, do like I did and test it in the car for a few
months before using it in the plane.

I completely agree with you that this is a hard market to compete in,
simply because there are so many good options available at a wide range
of price points.

Ernest, because I don’t want the $5 charger killing my +$1,000 audio in the airplane.  I have gone through a handful already in my airplane.  They are not all created equal.

Good lord, people!! You can pick these power regulators up every day that plug into a cigarette lighter for $5! They are all an LM357. I have a junk drawer full of them. And, the cigarette lighter jack is good for older equipment that is configured for it. Why would anyone ever pay over $10 for one?



Why is aviation expensive? Because, people are will to pay for it?

Wow! I should hope they got good reviews... Based on today's exchange

rate, the Charge 4 is a bit over $257 (plus shipping)! You could

purchase eight of the SteinAir version for that!



Another one worthy of consideration if you need/prefer a "horizontal"

charger would be the Belite Aircraft USB Dual 2.4 amp charger, which

sells for $75. It can be seen at

FWIW, I purchased a single USB plug unit from Stein a few years ago.  Charges at 2amps, no interference noticed, looks good panel installed.  Wish a two port version was available from Stein back then.

John,


Thank you! I don't know why I didn't think of checking SteinAir. That looks perfect.
