USB power outlets

Hi all. Anyone know how much juice the USB power outlets put out? Just curious.

I believe the standard is 1.2A. I would install one the puts out 2.4A. These provide better power to Ipads and other power hungry items. The 1.2A ones barely charge the cell phones when not being used and take FOREVER to fully charge. That's my current experience anyways.

Stein has good one like these:

At this point, I'd recommend looking for a device that supports USB QC or PD. Its not just a matter of amperage anymore.. its also the output voltage.. and negotiation with the device.

With the proper charger (PD), the iPhone will negotiate a higher voltage and be able to charge in 1.5 hours vs. about 3 if it were stuck at 5v/2.5A.

I'm looking to retrofit with this: https://powerwerx.com/panel-usbc-pd-...very-qc30-blue

Sorry thought it was obvious. I'm talking about the ones that come standard in the RV-12 avionics kit.

I replaced the one between the seats in my legacy RV-12 with q dual outlet I bought on Amazon and put in a switch since the original design had the receptacle wired right to the battery and my receptacle has a light that might drain the battery.

I replaced by USB power outlet today with one that supports USB PD. Here's the 5 minute video of the job:

Just by looking the referenced PD 18W Powerwerx unit seems to have a nylon or ABS plastic housing. Which is probably just fine for a center console of an RV-12.

However, when mounting on the instrument panel or near systems runs I always try to pick these ports when they have a metal housing for shielding (usually Aluminum). The transformers built into these USB ports can tend to put out EMI and the metal housing shields that an order of magnitude better than ABS plastic or nylon since those materials are invisible to EMI. Here is a link to a $13 all-metal body example with two QC3.0 ports and one 30W PD USB C port from eBay shipped from NJ:

Here are some pictures of others with 20W PD for a bit less $ but shipped from China (yuk):

I like that one better.. man, wish I found that first.

Although the spec sheet doesn't list the input current rating, or how it should be fused.. the output max is 60W (12v x 5A).. which is fine.. but I'm sure there are some DC-DC conversion losses.. so it might be possible to pop a 5A fuse if you plug in 3 devices and they all want max power (unlikely, but possible).

For that price, I might buy it and test it on the bench... and swap out the part I just installed.

In all honesty I might lean towards a two-port version. An aircraft is the last place I would want somebody to plug too many high-amp devices into one source. I mean, all these things are made in China on the cheap all the while advertising perfect specifications. And to make that concern pointless at least they are fused. But I have installed and see discussions here about having great luck with the $10-ish high-amp metal housing power ports.

I just checked on my 12iS and it is the same outlet shown in post #2.
So the answer is each jack puts out 5 volts 2.4 amps.
