    The front USB outlet in my 2021 doesn't charge the phone plugged in to it. It just seems to be for connecting Android Auto with no charging. Am I missing something? Using the phone's GPS while driving, or playing music from your phone is sure to drain the battery relatively quickly. I can't understand why the outlet doesn't supply power. Only the rear seats get phone charging?

    Yesterday it did charge the phone while using Android Auto, but two times the day prior it did not. I'll have to get a new cable and see if something's wonky there.

    I am having the same issue. Not the cables or phone tried various and the back chargers work. Apple play won’t work either. Then it does. Front wireless charger experiencing same glitch, on sometimes won’t turn on with the button.

    No, that's the way a LOT of cars USB ports work.
    The "front" port is there as an AUX input only and supplies only enough power to keep a 10 year old basic phone charged. Most phones will charge a little if the phone if OFF or completely idle.

    I think this is a major oversight on the part of car makers.
    Some of them do it right.

    You have to use it if you want to use Android Auto or Apple Car Play. I don't know of any phone that has separate USB ports for data and charging. That means you're forced to choose between navigation and charging.

    I'm sorry, but Toyota really flubbed the design here with the front USB situation. Why one Earth would you put only one USB outlet in the front seat area when two are required just to use the head unit to full capability? And why would you design that one outlet so that a connected phone would lose its charge? This is one of those design choices where I'm truly at a loss for words. I can't fathom what they were thinking.

    Apparently Toyota couldn't imagine a scenario where a driver wants to charge their phone and use Android Auto as they drive down the highway listening to music. And let's not even get crazy and add a passenger who also has a phone they'd like to charge to the mix. That's beyond all comprehension. :confused:

    It seems like every other car company on the planet understands that mobile electronics are proliferating, and they put more outlets of various types in their cars. A lot of cars have multiple 12V outlets, multiple USB outlets, and even 120V outlets. Toyota is the only company I know of that's actively reducing the availability of outlets for portable devices as time goes on. It's doubly baffling as they're a Japanese company, a society which is renowned around the world for being on the technological edge.

    Somewhat exaggerated, I think.
    The "input" USB port is supplied with the entertainment head (radio).
    Toyota does not build them. The company that DOES build them doesn't care.
    But Toyota could cause them to care.......and they don't......or didn't for a long time.
    I don't know if new models are still like that or not.
    But I DO know that a lot of different brands of care WERE that way for a LONG time.

    How is it an exaggeration to say Toyota is subtracting electrical outlets from their cars while other manufacturers are adding them? It's an objective fact that can be verified by anybody.

    If you sent your kid to the hardware store to grab a socket set that had a 1/2-inch socket in it and he came home with a set that didn't, would you accept his excuse of "I didn't make it"? When any organization, including Toyota, procures products and services they do so with a set of specifications. If Toyota isn't specifying that the head unit needs to be able to function with Android Auto/Apple Car Play while playing music from a USB device simultaneously, that's completely Toyota's fault. Likewise, if they don't specify that a device connected for Android Auto/Apple Car Play must receive enough current to function for as long as it's connected, it's also 100% their fault.

    Everyone is right about the shortcomings of the front USB, may I suggest a work around.
    Get a 12V plug charger powerful enough for your device, and use the 120 Watts available half an inch from the useless USB music interface.

    Ah! The obvious approach. :D (y) I have one and it charges both our phones as well as the dash cam, and (on long trips) the Garmin GPS. Oh, and it has a little display that shows the 12V level as well as three more 12V outlets in case I need to power another 12V device like a GPS power adapter or something.

    Except, I was under the impression that you need to connect the phone to that USB data port to use Apple's Car Play. Or did I misunderstand?

    That means you can't use the sole 12V outlet in the car for anything else. In my car it is already in use for an inverter. Used to be fine back when Toyota had 2 12V outlets in the car.

    Correct. You have to choose between Car Play/Android Auto and charging your phone.

    You could get one of these to solve that problem.

    You're still splitting 120W between all devices where you used to have 240W available. That product can help as long as your phone charger isn't PowerDelivery or QuickCharge capable. Otherwise you may pop the fuse trying to run the inverter and charge your phone/tablet from the same outlet.

    Obviously you’re still constrained by the 120W limit on the PP. There is no changing that easily. But the adapter allows you to plug in a second dongle.

    The USB connector on the Prime is intended as a data connector and not a power supply for charging anything.

    You can work around this by getting a powered USB hub which plugs into the Prime's USB connector and is also powered by connecting to the 12v power outlet or other 12v power connection.

    These kinds of powered hubs are readily available to home or office use and usually cost about $10 to $15 and come with a small "wall-wart" power supply that plugs into a 120v AC outlet and provides 5v DC to the hub. They're used when you want to connect multiple devices to the USB connector on your computer and need power in excess of what your computer's USB connector can provide. You could acquire one of these and make your own power cord to plug it into the Prime's 12v lighter-style outlet but I couldn't promise that it would like 12v DC from the car rather than the 5v DC from the wall-wart.

    Or you could get one of these devices:

    You'd need to get a cord to go from the green connector to the Prime's power outlet, but that should not be hard. Just get any cord with a "lighter-style" 12v DC connector and connect the other end to the powered hub. (Note that this device says it's happy with anything from 7v DC to 48v DC, so your car's 12v DC should work fine.)

    My 12V outlet is already occupied by an inverter. All these workarounds will have a pile of hardware on my center console and no room for cups, or to set the phone down. Will Android Auto work through a USB hub? I'm heard second-hand accounts that it will not.

    I think the real solution for me is to install what Toyota neglected to install - a second 12V outlet in the rear seat. I'm not eager to tear apart the center console for that project, though. The more difficult problem to address is the paltry single USB port.

    If everything were as it should be, one would be able to plug their phone in and enjoy using Android Auto/Car Play while the phone charges, the front passenger would also be able to charge their phone, and the stereo could be playing music from a thumb drive connected to another USB port. I don't think there's a realistic solution to that problem given the hardware in the car.

    Get a better cable. My 2021 PP charges through the front USB. It's not a strong charge, but it does sustain the battery in my Galaxy 20 while using Google maps.

    Also, why not just plug into one of the backseat ports? Keep a 3 ft cable plugged in and pulled into the front area and Bob's your uncle.

    You can't use Android Auto from the backseat ports, which is why I was saying you're forced to choose between charging and using Android Auto.

    I have an iPhone 8 and the phone charges when plugged into the front USB and using Google maps on CarPlay. About a 25 minute ride charges the phone about 15%. Not fast, but the GPS does use a bunch of power. This works the same as the 2019 Sienna we have.

    Since you have AA, your head unit is different than mine so I suppose your charging could be different as well. I'd still try a short, brand name USB cable and see if it makes a difference. Although USB is a standard, some cables are definitely better than others.

    Our phones charge just fine via AA use/port.
    Tip - the monoprice atlas flex cables are cheap and work well. A while back I was able to get a couple USB A to C for $1.xx ea (closeout on that color/length)
