How much amp is in each port and is there one that has more amps? What amps can you get plugging in 4 devices vs 3 vs 2 vs 1?

The product images show that this outputs 4 amps max. I don't own this product, but my guess is that each port is 1 amp.

Sorry, I cannot really help. I have no devices like iPads that take more current to charge. Mine is used to charge 2 iPod Touches and two vanilla (old, not smart) phones. I also use it to charge a Kindle and occasionally another device or two. None of them high power. For my purposes, it works great.

The charger has two 2.1A ports and two 1A ports. When I plugged in both my iPhone 5 and external battery pack to charge them both, I noticed the charger getting hot. I purchased this charger simply to charge my Trent PowerPak Xtreme battery, and it works well for this.

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)

Sorry, I don't know the answer on the exact amps. Is there a specific reason why you might want 2.1a on both sides? All I can tell you (a non-electrician) is that it supplies enough power on the right side to charge an ipad (but not on the left). So, I suspect that it can't be sharing (1A on each) as that would not provide enough power on the right to charge an iPad.Hope that helps.

All multiport USB chargers will split the power between the ports but this one is 3A. One port will get 2A and the second 1A so it is sufficient to power all new devices that require 2A charge (like iPad and large screen smart phones) and use 1A port to power second device without compromising on time. Just make sure to use original device cable.

To answer your question yes is port supplies the 2 amps. Each USB port is dedicated. Unlike a hub that would split power. I had two iPads connect as well as one iPad and one iPhone and it worked perfectly

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.

'Over-amping' a device is impossible by the laws of physics. So no worries there. The amperage listed per port is the maximum that port is capable of supplying. A device will attempt to consume the amps it was designed to up to the limits of the port it is plugged into. More amps means faster charging.This is all before Apple enters the picture because they do strange things to try and force their customers to buy only their products. So a 2A 'apple' port may not supply the full 2A to non-apple devices and vice versa. Unless Apple got their act together which I doubt...

Yes. One port is a bit faster than the other but we do plug in two phones or a phone and a tablet. The tablet works best in the 2.1A port. I like mine very much. It sticks out less so less in the way. With the red color you see it at a glance.

Well it does have three ports and I believe one is 3.0. Not absolutely certain on it, because I don't really know much re differences between the two types.

I really wish people would look more closely at the product. I myself am trying to find the same information as you and almost bought this unit. However, taken directly from the manufacturer's website (Accell), I found the following: USB CHARGING: 2 Ports, 5V, 2.1A Shared. So unless the manufacturer incorrectly described it's own product, this, just like most others, have a total of 2.1A for all usb ports. If using both usb ports at the same time the 2.1A will be split, reducing the charging time of 2 devices (ipads, tablets).

MANUFACTURER RESPONSE: Thanks for asking! 2.5A is the total power available from the power supply- NOT the amount of power available to ANY ports. To say that another way, you would have 625mA (.625A) power per port max when using all 4 ports. The max current draw for a device complying with the BC 1.1 specification from any given port is 1500mA (1.5A). Please note this full current draw would be available to only one device at a time. When charging 2 devices simultaneously, we would expect charging at a max rate of around ~1250mA (~1.25A)- assuming no current is required by devices in the other two ports. Sorry we can't offer a more clear explanation here- USB charging is really a complex topic where devices from different manufacturers have very different behaviors. To top that off, many devices actually negotiate with the host PC to determine what rate to charge at, so behaviors on these will vary depending on whether a host PC is on and awake versus when there is no host PC or when the PC is sleeping.

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.

usually the adapters for each device have the amp info on it-very small writing. if not, check the devices user manuals.

I would check with Wagan to be sure, but as near as I know the output from any port is standard USB at 2.1 amps. I hear some Samsung devices have problems due to their proprietary wiring of USB.

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

there are 2-3.0 ports and 4-2.0 ports in the back and 2 2.0-ports in the front. a total of 8 ports.

You can plug in any 4 USB devices you want. I have 3 charger USB lines and an accessory in mine.
