Will it charge the 3 amp HP Chromebook 11? If i use one port will the other one go as high as 4.2amps for example? Or are the ports limited to a max

I don't know about the Chromebook specifically. It will charge anything else I own and I don't get the "not compatible" message on any of my equipment, including Apple products. If you use one port the other will not go to 4.2 amps. Just deduct the amperage the other equipment needs to charge from the 4.2. Yes the ports are limited to a max 2 amps per port if two devices are connected and the ad on Amazon confirms this too.

Each port is 2A. You can't combine. Since this is a smart charger, it will likely very slowly charge your chromebook. It might be so slow though thtat the chromebook says it isn't being charged.It worked well for tablets and mobile phones until it broke. At $11, worthwhile.

I believe each port is rated it at 2.1 amps, which the max for each port, I hope this helped

Normally you can use these USB ports for charging , it works , but not the same as a standalone device charger . A single USB port's power specifications is 5V 0.5A when a standalone device charger is 5V 1A , it will be very slow when you using a USB port for charging and that's why we say "USB hub only, not a standalone device charger"

I'm actually using a spare one for that function now. HOWEVER, it will only charge items at the USB limit of 500mA per port. Most true chargers are capable of 700mA to 1000mA depending on the device.

If your laptop can be charged with 9 or 12 volts, and it draws no more than 4.5 amps while charging, then yes. However, I'm pretty certain that most laptops require around 18 volts for charging, maybe a chromebook could be charged with this guy, but I would need to check. If you want to post a link to your laptop I could tell you with certainty whether or not you can charge yours with it.

I couldn't tell you. The one I bought charges my chromebook, but I have to connect a usb mouse because the touch pad is very glitchy using this power cord!

The one i have has a spot for AC power for those devices that need more power but its best for low power devices. cord on mine is 4in. approx.The slots are running parallel but share the 5v USB power so there will be a drop on power between all devices.

They both are connected to the same circuit inside, and it is the total current of 3.1A that matters. So any one of the port you can use for charging a tablet (and it will take 2.1A current from that port), and the other port can be used to charge a smartphone (which will take 1A current from that port). Thanks!

Yes. I have a slightly different model of HP chromebook, but I am confident it takes the same power cord. I verified using a search and found this evidence as well: http://www.ebay.com/itm/Hp-Pavilion-Chromebook-14-c010us-c015dx-c025us-c050nr-c050us-Ac-Adapter-Charger-/370855339111 Hope this helps! --Chris

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.

No. The only ports are two USB 2.0. However, you can buy an adapter for your memory card that plugs into a USB port for a few bucks. Alternatively, you can pick one of the Acer Chromebooks, which all have SD card slots included, though their overall build quality, screens, keyboards, speakers, etc are inferior to the HP 11, so it is a trade off.

The USB 3.0 standard is .9A per port. So with a 5V, 5A power adapter, you can only connect five bus-powered USB 3.0 devices (.9A x 5 = 4.5A) before running into problems. You have a little more flexibility with USB 2.0 at .5A (can use all ports except the charging port), but if you're going to do that, you might as well buy a USB 2.0 hub and save some money. Anker has a similar product (9 USB 3.0 + 1 charging port) that comes with a 12V, 5A charger. The power adapter is not a wall-wart...it's a brick similar to what laptops use, and it's bigger than the product itself!!! It adequately powers nine USB 3.0 devices and an iPad because of the whole Volts x Amps = Watts thing and some undervolting to allow the 12V adapter to power 5V devices.

Hello Tim. The USB ports can be used for charging one 2.1Amps device or two 1Amp devices.

It should be similar to your charger. If you use a two amp port it might be quicker if the device allows it. I have never timed it versus my charger.

My understanding is that 2A is the maximum. If you use one usb port, that port will get the 2A. If you use both the current will be distributed. 4A seems too much to take from your car battery anyway.

HiActually your laptop need 45W (19V 2.37A) and this charger Output: 19V 3.42A. so the output is more than you need it, its working but not good for your laptop and Hardware..... ,search to charger output 2.37 A Best RegardsEng.Yasser

Because you devices negotiate with the computer they are allowed to draw more than 1/2 amp. A "Charging USB Port" will only supply 1/2 amp and will shut down if overloaded. Try one device at a time. From Wikipedia " The USB Battery Charging Specification Revision 1.1 (released in 2007) defines a new type of USB port, called the charging port. Contrary to the standard downstream port, for which current draw by a connected portable device can exceed 100 mA only after digital negotiation with the host or hub, a charging port can supply currents between 500 mA and 1.5 A without the digital negotiation. A charging port supplies up to 500 mA at 5 V, up to the rated current at 3.6 V or more, and drops its output voltage if the portable device attempts to draw more than the rated current. The charger port may shut down if the load is too high."
