    Hi,

    I'm looking for an USB power adapter to power on the switch when in nomade mode.
    Apparently the specs of the official AC adapter are 5-15V for 2.6A in output.
    The specs of the non-official ones for the Switch are 5V for 2.4A.

    The most of USB power adapter i see on online markets are 5V / 2.4A.
    So, is it enough to load the Switch in quick charge ?
    Also, do you know if Qualcom quick charge is supported ?

    Thanks !

    Yea this is the question i have been wondering.
    The offical switch says 5-15v like you said.
    From FFC testing sheet, they say the battery is 3.7v like the 3ds ,cellphone etc.... (any usb device that has a battery pretty much)

    but this 15v have me wondering.
    I know the macbook and some other laptops are usb-c but needs 13-20v in order to run and charge.

    I do hope the switch is simply a normal usb device and it will charge via any usb3 wall charger. I guess only those 2 guys with the leak systems would know.

    For those electrically challenged volts X amps = watts. So 5V x 2.6A = 13 Watts and 15V X 2.6A = 39 Watts. 3 times the energy. The likely scenario is the Switch needs the full 39 watts to charge and play while docked and will need less to charge and play handheld due to lower clock on the GPU.

    The question is what happens at 5V (2.4 or 2.6 A) with standard powebanks. Will that be enough to charge and play, just play and hold charge, or play with some battery drain? Nintendo hasn't said.

    Ideally a powerbank would provide enough energy to play and charge as quickly as possible so you can ditch wire. Just a hunch but I don't think that is going to happen at 13 watts with that screen on.

    I have half a dozen various sized standard powerbanks already, I am not purchasing another until I know more.

    And yes 15V powerbanks exist but they are of course more costly. On top of that what a manufacture claims are the specs on a powerbank are not necessarily what they actually deliver in the wild. For example when devices are first connected there is a negotiation and then charging commences. The Nook has some issues with some powerbanks and if it doesn't get the full (2.1 or 2.4A) from the powerbank it then negotiates down to only .5A which is crap for a tablet. Don't rely on listed specs, rely on actual tested results from those with the proper equipment to actually measure.

    For more detailed information check out "NLee the Engineer" on amazon, he is a top 10 (not 100) reviewer with an emphasis on rechargeable batteries and light bulbs.

    yea comes with a big usb charger.
    This charger will be mounted to the dock.
    So most of us will need another charger if you take the switch outside your house.
    It being able to charge via a normal cellphone charger would be great. Vs having to buy another one from nintendo for $20

    Yes, but generally you'll probably leave that connected to the dock.

    Compatible does not mean it will get its intended job done. That thing has a max 2.1 amp port. That thing will not even charge my iPad at its top 2.38A charge rate. Don't you think a gaming tablet is going to use a little more energy than an iPad?

    A standard bicycle hand pump is "compatible" with the 17" tires on my Jeep. It will even go up to 70 or 80 psi way beyond the 32 psi my tires need. Do you know how long it would take to inflate a vehicle tire with that thing?

    So nome no name chinese sellers are claiming their stuff works with the Switch on Amazon. What has Nintendo said? is there any evidence?

    The "This manufacturer said so, so it must be true" mentality has got to stop.

    I think the 15v is used by the dock to power usb ports if accesories are connected on it.
    So maybe a 12w (5v/2,4A) is sufficient for charging in nomade mode...

    True.

    Better to wait for an official third party maker like Hori to release a licensed Switch power bank.

    That may not even be necessary as officially licensed will carry additional costs, but knowing what the necessary performance specs we need from the powerbank is. (see wHori mSD card)

    I understand why Nintendo hasn't made this information public yet. Only a small percentage of the user base is going to be concerned with such things. "Ok my 3 hours is up need to plug it in, derp de derp." You would be surprised how many people do not even know of the existence of powerbanks for smartphones as it is or they saw one in SkyMall at $150 and blew the idea off.

    They don't want to muddy up their main message right now with all these configuration details like, power accessories, phone apps, Bluetooth, and "bulky gamer headsets" the general public starts crossing their eyes at and thinking "this shit is to complicated", screw it. They also want reviews to focus on the games and the fun, not specs and power delivery. "You get at least 3 hours of Zelda". That's all 98% of the people need to know. Us geeks that spend our free time arguing about analog vs digital triggers are not their concern right now.

    I'd imagine it uses the 15v when docked. 5v is probably used while mobile.
    They have stated that the clock speed is reduced while mobile so it would make sense.
    Plus you obviously want to use less power when mobile for battery life.

    I'd imagine if you get a 5v @ 2.5A ac adapter/battery bank, it should work fine for mobile play.

    Have to commend the power savings vs xbone/ps4/pc. Especially vs PC, those 1000watt rigs are causing quite a bit of greenhouse gasses. My gaming laptop is a mere 130 watt max but it's still quite a bit more than the switch.

    that would be very crapy to cut the system by 10volts when in mobile mode. And what if you have it in handheld mode but on a charge does it auto switch.

    Still so many questions and nintendo has said nothing.

    Well only about 13days left and these question will be answer. First thing im going to do is hook it up to my usb charger

    Some other points to consider which raises additional questions.

    We know it has a USB C connector but we don't know if it is USB 3.0 or 3.1 (at least I don't know)
    USB 2.0 spec is .5A minimum per port.

    So this leaves us with 1.6A for the Switch and the USB C port on the dock. That is not much. I am really starting to wonder how fast the Switch can recharge its battery while docked and playing at the same time.

    yea thats what ive been saying.
    I guess the first thing im going to do is try out different chargers and see what works.
    I know my phone needs at lest 1amp in order to do anything. those little .5 and .7amp chargers wont do anything but get hot.
    So i wonder if the switch can be charged with the 9v 2amp fast chargers, or normal 5v with system off or what the deal is.
