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

I use this purely as a charger not as a USB hub. The key is being BC 1.1 compliant. I charge an iPad and iPad mini at the same time. It can pump 2.5 amps max across all ports. It will charge all 4 devices at normal USB rates but if you only hook up 2 devices they should both charge twice as fast! (1000 mA rate)

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.

It has no 'amps' per se. This is a passive,not powered, hub so it will be able to source no more total current that the USB port that it is connected to.

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

No, there are no problems if you charge cell phones on a 2.1Amp port, The rating shown here is a limit. so let's say your phone only allows charging at 0.7 amps, You can put it in any of the 4 ports.But let's say you have a tablet that can take up to 1.8 amps you can put it in the 1 amp port but it will just take longer to charge unless you are using it at the same time where it may not actually charge it would just keep you at the same level while you were using it.

I have the HP 10 inch, I am not sure what other specs might be needed in order to answer your question. It works just fine w/mine. However, I did notice that the charger would get hot initially if i attempted to charge and surf. I simply allowed it to charge fully before operating.

Haven't tested this one specifically but almost all that have been legitimately tested that are similar to this one have 2.4 total so if you have one item plugged in it will draw up to 2.4 a. If you have two plugged in the unit will allocate the 2.4 amps between both items but no more. There are plenty of chargers out there that will deliver a full 2.4 amps to each usb port but they are a little more expensive.I hope this helps and good luck!Chris

I'm sorry Demetre but I don't know. Perhaps you can find the specs from the manufacturer. It worked just fine for the 2 or 3 things I had plugged into it. It was just a stop gap measure until I could get my new laptop online.Bill

Most PC's and chargers limit the current to about a 1/2 amp. That's due to the USB 2 spec. There are a few, such as Apple, Kindle, and others, that charge at higher currents. I would have no reservations using this extension at 2.1 A. Go for it.

Either port will charge fine but the 2.4 is faster. Its similar to the difference between plugging it into your computer to charge (1 amp slow) or a wall charger (2.4 amp faster). Both will do the job one is just faster.

The standard is 500mA for USB 2.0 and 900mA for USB 3.0. Do the math, and you'll see that the power supply doesn't cut it for 24 USB 2.0 and 4 USB 3.0 ports. 24 x 500mA = 12A 4 x 900mA = 3.6A The power supply would need to be 15.6A at 5V. Since the power supply is only 4A at 5V, you're only going to be able to power four USB 3.0 devices (900mA x 4 = 3.6A) OR eight USB 2.0 devices (500mA x 8 = 4A). Perhaps Manhattan should do what Anker does and use a 12V adapter and whatever they do to undervolt/cut down their USB 3.0 9-port hub to 5V per port (that thing comes with a 12V, 5A power adapter! The brick is almost as big as most laptop power bricks!) Using the formula of Volts x Amps = Watts (5V x 15.6A = 78W), we can conclude that at 12V, only 6.5A would be needed (12V x 6.5A = 78W). It's a shame, though, as a 28-port USB hub is cool as all hell, but in practice, it doesn't work right unless you're using all self-powered devices (devices that have their own power adapters).

It works with x3a - 19v ac adapterIt does not work with x3c - 12 ac adapterPlease enter B00DUMFZ6O into Amazon search for Samsung Chromebook 303C seriesBest to allPWR+

I used mine to replace a charging port on a Acer laptop.worked ok, but was tricky. don't overheat the connections! use as little heat as needed to melt the solder. don't overdo it on the heat. hope this helps.

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-/370855339111Hope this helps!--Chris

Yes - "Two high-powered USB charging ports with 3.6 Amps of charging capacity" I bought this and have no issue charging two of anything (including ipads) - love the product!

Nope. Use any port for any item, such as any phones &/or iPads or other tablets. Just do not exceed the 6.2 Amp maximum. Interestingly enough, I discovered that when I went above the max output of the charger it proceeded to charge 2 iPads & 1 iPhone while keeping the third iPad "on hold" until one of the other three items were charged. Then it polished off my phone. Hope this helps. This is the best of 4 chargers I have had. The other thee went into the trash.
