Qualcomm Quick Charge 2.0 devices can accept 3 amps @ 5 volts for 15 watts total, is this compatible with Qualcomm Quickcharge 2.0 at 3A charging?

beau. this one here has two ports. one @ 2.1a and another @ 1a. i dont think this combines both porta for a total of 3.1a.

I asked an engineer at work about this. As long as the voltage matches, and the amperage does not exceed the limit of the charger, the device that is being charged will take only the electrical energy it requires. It won't hurt it. If the amperage of the device being charged exceeds the amperage limit of the charger, the charger may burn out.

I think it's restricted to 2.4 amps per port, however, this should not be an issue, no device that charges using USB pulls 4 amps

This won't even charge modern cellphones as fast as most car-chargers (or that type of USB output that you plug into the cigarette lighter) can do. RE: John Taylor's misleading answer.2.1amp standard for USB3.0 and newer USB2.0 * 5volt standard USB socket = 10.5 wattsThis product's 0.5 amp * 12v = 6wattsUSB3.1 in 2015-16 = 100 watts!!!!! Try to wait for charging products that accomodate USB3.1 if you can; it's a HUGE jump in wattage & e.g. my Galaxy Note2 (USB2.0) take 8+ hours to recharge; also expected in 2015-16 are 1080p 3D head-mounted micro-LED displays worn like sunglasses for <$500 (mass-consumer price range) that draw ANOTHER 7watts or so.

Yes one of the ports is 2.1 amps and will be able to. I have an LG G2 and it charges great

I think this was 5V/1A output. Its a little slower than plugging it into Wall. Yes it will take longer for phone to charge on 0.5A than a 1A. There are a few chargers like Alpatronix which have 2.1A output as well.

Don't know, but it puts out 2.1 amps. I found it enough to charge all of my USB devices.

There are many USB chargers, max 2 amps. The 1 amps give a better charge, the 2amps give a faster charge. I used the one that came with my cell phone. All USB ports are supposed to put out the same voltage which is around 5 volts. So anything that will charge through a USB port will work.

My Nokia N900 came with a 2A quick charger, and can charge from either slot. Essentially, if your device can use a 2A charger, using the 2A port will work just fine. If not, your device will likely limit it's own intake to 1A anyway. Without data communication, most devices default to 200mA or 500mA anyway (USB standard) to not over-tax the source. To get 2A use one usually has to use a cable designed to trick the device (commonly shorting the data pins) to do this, or change it's settings once connected.

Read the USB wall pack's voltage input range. If it is ends up being only 110/120VAC 60Hz, then you can use another comparable output USB charger (amperage needs to be equal to or higher than the supplied pack).The USB side of things is not an issue, as 5VDC is the USB standard, so a wall adapter with USB charging ports on it will work just fine, so long as it is able to supply enough current (amps).The wall adapter is relatively inconsequential and equivalent ones made for your power grid are easily found if this one ends up not supporting your power grid.

Well, all I can say is that I use it with an Anker battery pack, which says 1.5A input current.As far as I know these new chargers, which output via a USB connector, establish sort of connection with a device being charged. And the device itself will only take whatever it is capable of.So it's not like the charger will shove those 2Amps down the device's USB connector.Your device is supposed to support whatever current is listed on the device. Otherwise it will just use as much as it is capable of.That's what I've been told.Hope this helps.

As others have stated you can't exceed 2.2 to 2.4 on a given port, but that wouldn't matter, because it isn't the charger that decides the amps to charge at it is the device. The only thing the cable and chargers do is supply enough amps and low power loss. An average device won't pull above 2 amps regardless of the output of the charger. The S4 pulls 1.8amps at its full draw and its oem cable and charger are rated for 2.1 if i remember correctly.

Sorry I'm not sure about the compatibility side! I never purchased the quick charger I just use the factory supplied cord for the hd disc video camera with battery still docked in camera and it only takes about 30mins or so and last a long time ill put it this way the small blu ray disc are able to burn 45mins hd and I do 2 of them with no problem! Ive had the batt 3yrs with no issues. I hope that I helped you and sorry for the late reply! Regards,Pete.e

The input voltage is 120volts. 60hz @ up to 14.5 amps. So up to 1740 watts ac. Hopes this helps. It's a great charger just it is heavy and the clamps are bulky. Compared to the Midtronics. But in my opinion this is still the better charger

No, the first two (5 and 10) are Watts, not amps. At 2.1A, this provides about the same power as the 10W iPad charger (multiply by 5V, which is USB standard). I have this outlet and it does seem to charge at full rate.

@Eric never mention any 5.1V. To answer your question this charger is stock OEM rated at 1.2 amps the phone itself can also be charged by a 2.0 amp charge it was design for that if you happen to come across a generic charger rated at 2.0 amp.

The first answer is a bit off, because they did not consider the step down from the power supply at 12V to the USB slots at 5V. The power supply is 5A at 12V, or 60 watts. The 9 USB slots provide .9A each at 5V, for a total of 36.5 watts. Add the 2.1A at 5V for the charging slot, and you have a total of 36.5 + 10.5 = 47 watts. This is within the capability of the power supply. So, you should be able to deliver the full rated power to all of the slots simultaneously.

I am puzzled by your questions. The question about the Pwr+ 5V 2A Rapid Charger appears to be, "Does it come with a charger?" This product is considered a charger, or charging adapter, for any device with a micro USB connection that prefers 5 Volt 2 Amp charging. I hope that helps!
