please recommend USB outlet that works Boondocking

[towpro]

I charge my phone at night. one of the new Androids that uses the Turbo charging system 2X.

My Wolf Creek has a USB charger built into it, but it don't even work when the shore power is plugged in.
There is also a 12V outlet present.

But when I am boon docking, I don't have 120V and the 200W solar only boost the voltage during the day time but I need to charge at night.
I have Two 90Ah 12v AGM batteries,so surely I can afford to charge a phone.

can any body recommend USB charger that meets the following:
1) will run off 12V. standard 12V car type plug, OR replace my 12V USB adapter that is in panel mount.
2) Will run off 12V, meaning batteries are not being charged by solar or AC power, so it will not be 13.X volts, it will be 12.4v-12.7V that you see with a battery that has a little load on it.

all the car chargers seem to be designed to be used when the car is running, which means they see 13.X volts

Make sure it is 2+ amps for every USB outlet

Example on amazon

thanks.I found one on amazon, plugs into 12v outlet, and had 2 outlets.
one outlet is Charge 2 for my Android and the other outlet is standard USB for her apple. hopefully this will work as we become less dependent on shore power and more dependent on solar.

I did monitor today as I lifted the camper from low level up to 40" to load it on my truck, all done without AC hooked up, when I was done I went in and Bogart still said 100% charged. this tells me that all 4 jacks running was supported 100% by my 200w solar system 🙂

What Jim said.

I use a standard 99 cent usb car charger, off my house battery.

Or, if I want to be extra inefficient, I use the usb socket on my 120v power strip that is plugged into the inverter ;). I figure it doesn't matter much, for the amount of juice a phone uses.

I just use a 12V adapter in the lighter plug.

I haven't actually had a problem charging with a 12V power outlet and typical cell phone charger.

I use a Samsung charger that can do adaptive charging for my Note 4 and we use an Apple certified charger for wife's iphone. https://smile.amazon.com/gp/product/B00FK6G59O/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 is the one we have for the iphone. It's a fast charger.
