WTB Bare wire USB charger with 3+ ports

Looking for a USB charger for a minimum of 3 devices in the plane.

Looking to power:
TF700 with Avare
Stratux
Dynon D3
maybe more...

The Anker charger listed above is radio quiet, but I have experienced the cigarette lighter plug spontaneously withdraw from its charging socket leading to failure to provide power to my tablet... Would be nice to not have to worry about the Anker charger losing power. Would be nice to have more than 2 charging ports.

There are plenty of 120v multi-port USB charging strips.
Are there any radio quiet, mulit-port, 12v USB charging strips?

Maybe a couple of these?:

I have an early D1 PocketPanel. I ordered a second cigarette charger, took it apart, molded a fiberglass surround for it, and wired it to my avionics buss. No extra wires running over my panel.

I think the blue led's on the Amazon one you linked would become an issue at night. JMHO. I have used this one in two planes, no noise at all, good performer:

Also installed one of these behind a panel for various devices needed for wireless HUD testing, works great, no noise:

Love that 2nd one (star tech) but reading the questions and answers, it appears the amp rating per port may be low.

That star tech powers my Skyradar to GRT link- USB 2.0 means a measley .5Amp. No good for device batteries. Runs panel lights, host a bluetooth dongle and the Thumbdrive.

$70 USB 3: has been out a while, not QC or anything special, might be worthy.
