This is a review of Anker 3.6A dual usb port wall charger: http://www.amazon.com/Anker®-18W-3-6A-Wall-Charger/dp/B00B8L36A6/
Just like cases, wall chargers market starting to get saturated with too many choices any time you search for one. But to find a good quality one that will live up to its current rating, have a reliable design that will not burn out, and with a relatively small footprint and dual output - that's not easy to find. I looked into testing of new Anker 3.6A wall charger to see how it will meet all these requirements.
First of all, the charger itself is very compact and lightweight. Under 80g with a dimensions of approximately 70mm x 55mm x 25mm it will be very comfortable to take with you while traveling. It's slim design is not obstructive if you either plug it into wall outlet (leaving enough room for another plug if its a dual outlet) or power strip where it could be used along side with other cables. For such a slim design it has a very impressive spec of 3.6A of shared output current between two ports. Obviously having a dual usb port is a huge bonus, but being able to supply 3.6A into both of them (combined and shared between two ports) or into each (if only one port used at a time) - this is very impressive! Yes, they have it labeled as one port being Android and the other one Apple, but while testing it with Galaxy Note 2 and Nexus 7 I found both ports work reliably to charge android devices. I guess this just means that you can also use it to charge Apple device with their proprietary charging circuit. I have another dual wall charger from about a year ago where I can't charger Android devices from "apple" port. This Anker charger, which I verified with their car charger as well, has no issues powering up Android devices I tested from their "apple" port. I also verified with my Note 2 that charging current was at max 2A, so the phone will be charged up at maximum speed. Furthermore, I had both Note 2 and Nexus 7 plugged in together, both charging as AC in battery setting, and I have verified Note 2 sinking 2A. Also while charging, I didn't feel any overheating, it stayed cool.
Definitely a highly recommended wall charger and a great value for under $12 for 3.6A dual port slim design which is covered by Anker's 18-month warranty.

I got this little guy ahead of your review, and can't agree more. Charger does the job very well on either port.
Thanks just ordered one. Been needing one for some time now what with three tablets and four phones. This will come in handy and with Amazon Prime's free shipping is a nice little deal.
One thing I have to mention is that when charging Note 2 and another Android non-Samsung device, I would recommend to keep Note 2 on "apple" port while other device on "android" port. I had two Nexus 7 tablets charging on both ports, starting at the same low battery level, and found the one connected to "android" port was charging at a faster rate. Bottom line, Samsung phones charge at fast rate from both ports, while other Android devices like Nexus 7 charge faster from android port versus apple one.

That explains some of the debate going on in the 2 amp car charger thread.
Some people were saying that "apple" 2.1a ports won't charge the note 2 quickly when others were saying it charged their note 2s fine. Maybe you should go report your findings in that thread too?

Hi, i'm a heavy user some days, so I need a compact charger I can put on my keyring. I thought I had the perfect one of eBay for ~$3 (http://www.ebay.com.au/itm/200720521235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649)
However, after several tests using "Charger Timer" I figured out that it only chargers at 500ma-thus making it take a very long time to charge. The point in this charger is to provide me with a quick battery boost ad-hoc, but it's pointless as it takes 1hr20 for a full charger(stock at 1000ma takes 40 minutes)
The seller offered me a replacement, but I'm not sure whether to take it incase I wait weeks then find out its the same low-output charger.
This is a popular charger (dx, eBay)-does anyone else own it? Does it work for you at 1.0a?
Can anyone suggest a cheap alternative compact charger?

i dont know if this would work for you or not, but I just ordered the Anker Astro Slim 3 and it has two ports that will charge at 1 Amp each. It is slim enough that i have been able to charge my Galaxy S3 while using the phone and stacking the charger directly behind it. So far, i am very pleased with it. I am attaching a couple of pictures so that you can see it. I am charging my nexus 10 and my nexus S in the picture. Hope this is helpful
Thanks for that!
But I'm after something much more compact.
I'm really surprised this isn't a common thing-having it on my keyring (even if 0.5a) has been incredibly handy.
Any other suggestions?
Sent from my GT-I9305 using Tapatalk 4 Beta
Has anyone got a suggestion for me yet?
I've finally received the one I ordered, and no surprise, despite being advertised as 1a, it charges slooowly at 0.5a.
Size of it was prefect- fit nicely on my keyring and wasn't even bulky
And then after a week, it broke...
I like Anker stuff as well since I reviewed a lot of their products (in my signature link). The problem is that it sound like you are not from US, Australia from your ebay link? That is always an issue because a lot of US companies deal only with a few international amazon. You mentioned DX.com - love their products as well, reviewed a lot of their stuff, always a pleasure to deal with, and they ship to Australia without a problem.
Here is my thought about your 500mA charging. Are you sure its not a cable? Most of today's chargers are 1A-2A (all new Galaxy stuff charges at fast 2A speed) while tablets like Nexus 7 use at least 1A. So it's easy to get 1A charging speed out of most of today's chargers since they all use a common voltage/current regulator chips inside. BUT, you will LIMIT your current with usb cable. A lot of these cheap cables are designed for computers, and a common USB2.0 PC port only outputs 500mA, and cables are made out of thin wire. Thin wire will limit your current, will overheat, and will create other problems. For 2A you need to use USB cable with a thicker wires. So just look around your house for different usb cables to confirm. Usually the OEM cable that comes with your phone will be designed for max charging speed of your phone. I like buying Monoprice cables, but again not sure if they ship overseas.
At DX, look for the HTC One chargers. After lots of frustrating purchases those were the only that I could find that delivered the mentioned current.
I think you may have trouble finding one that fits your country's wall socket.
Have you tried different cables? My S3 draws anything between 0.3 and 1A from my charger depending on the cable I use.
This is a review of Anker dual usb port 4.8A (2x 2.4A, total 24W) car charger. http://www.ianker.com/product/71AN2452C-WA
Just a few months ago I reviewed Anker's dual usb car charger with 3.6A combined output. One of the comments I heard back was about charging Note 2 and iPad 4th gen. As you know, Note 2 needs 2A for a full charge while 4th Gen iPad needs 2.4A. Or perhaps you got Note 3 in addition to Note 2 and need to charge up both of these 2A phablets in your car. In that case 3.6A doesn't cut it. The solution: 4.8A charger with dual usb port output each being able to deliver 2.4A.
Continuing with their new environmentally safe cartoon package, this one arrived in a neat little box. In addition to car charger, it came with Instruction manual which I want to mention specifically since Anker has been updating these with more and more useful details. They might as well call it a car charging Guide. But one thing I do have to mention, even so this charger has 2 ports labeled Android and Apple - in case of Note 2 or any other newer Galaxy phones, both ports can be used to charge your phone at full speed as I captured in the pictures below using Galaxy Charging current app.
This new 4.8A charger is the same size as their previous 3.6A model. Its very compact at 31g with 2.9" in length and 1" x 0.9" at the dual usb port opening which is smaller than some of the other single output car charger. This car charger is able to accommodate simultaneous charging of 2 plugged in devices at 2.4A each for a total output of 4.8A, and according to instruction manual has built-in multiple circuit protections. With Anker's standard 18 months warranty from the date of purchase, and a current price of $11.99 - this is one fantastic value and definitely a highly recommended accessory if you want to charge multiple power hungry devices at full speed in your car.
Here are the pictures.

thank you for the review! What micro-usb cable are you using to charge the device? I'm noticing that the cable has much to do with the amperage being drawn from testing I've done with all the cables and chargers I have.
Thanks again, Vectron. Excellent review.
By the way, how did you find the accuracy of the app you were displaying to measure the current?
I bought the USB power monitor that you reviewed. I d/l the app Galaxy current (the same one you
are using) and they never matched each other. The app always show 1800 like yours when the USB
gadget wasn't installed (on a 2A charger). It showed very differently with it inline, like 1100 mA.
I wonder if you saw the same thing?

To be honest, the app and usb dongle are great for relative measurements, not the actual accurate measurement. That is a truth. When you have a dozen of different cables and chargers and trying to make sense out of it, these tools come very handy to determine which combination will give you the highest charging current. Is it accurate? The only way to check it by dealing with a known mAh capacity target and timing how long it will take to charge it from zero to full (or some starting percentage which you will have to factor into your final calculation). Once you know total charged "mAh" capacity and "h" it took to charge, you calculate by dividing mAh/h to get your mA charging current speed. On a few occasions I came very close with what I have been reading with Charging Current app. But in general, just use all this as a tool to determine best combo of your external charger/cable.
Looking Nice......
I recently picked up an Anker dual car charger (link). It has two ports labeled Apple, the other Android. Both ports can supply 2.4A, for a total of 4.8A.
When I charge my phone from the Android side I get very close to 1A, but when I use the Apple side that goes down to around 500mA. To note, I used the same cable and only one port was used while testing. I used Battery Monitor Widget to track the charge rates.
Either side is strong enough to charge our phones, but it would be great if they both charges at full charge rates. So now I am looking for a wall charger and ideally I would like a dual port charger that can charge two Android devices at over 1.5A. I know we can't use 1.5A but it will future proof the chargers for a while, or will work with tablets.

Maybe look at getting a powered USB hub? I know the 2 I have at home can supply more than the 500mA USB2 spec as they've back powered my raspberry pi with a hdd attached before.
from my limited research, apple and android phones use different methods for signaling AC charging.
Android phones like to have the data pins in the USB cable shorted to each other to signal the phone for AC fast charging.
Not sure what Apple does, but it's not the same. That's why there are two different ports on the charger. Android ports have the data pins shorted together.
On a side note, you can also buy "charging only" cables on amazon that do the data pin shorting inside the cable. this may let you use your android phone with the apple labeled USB ports.

This is correct. Apple devices want to see some combination of 2V and 2.8V on the data +/- lines to signal wall adapter charging. They do it this way because it allows the charger to tell the device what amperage it's capable of delivering (500mA, 1A or 2A) which is pretty cool.
It's been my impression that even using an charging only cable/adapter an Apple charging port will only give you 500 mA.
For what it's worth I recently emailed Anker about this and they said as much. I don't have an appropriate cable or charger to test it on. But Anker also told me they will be releasing new chargers in December that feature their smart charging port which detects what type of device you've attached (Apple, Samsung or generic Android) and then behaves accordingly. I just ordered one of their external battery packs (Astro3) which has one of these ports for 2.1A plus 2 x 1.5A Android ports. A similar AC charger would be nice if you can wait.

This is a review of MPow 4.2A dual usb port car charger. http://www.amazon.com/Mpow®-4-2Amps-Charger-Android-Devices/dp/B00HLHHBHA/
Car charger is probably one of the most common smartphone accessories. We all like to take trips, stream our favorite music stations, keep our eyes on the traffic with Google maps, make some phone calls, and maybe even have wifi hotspot running for other passengers in the car. All this is going to drain your phone battery in no time. That's why we need to keep our phone on a charger while driving. And not just any charger, we need something that's going to source enough current to charge your phone at max speed. Let's take a closer look at what I found.
Both of the MPow car changer units, black and white, arrived in a nicely packaged box with a front display showing the actual charger. Taking it out of the box revealed a very compact dual car charger, about 3.5" in length and almost 1" across usb port side. When I say compact, I mean it was a size of a regular single port charger, while they were actually able to squeeze two in there. Another good point about compact size is that it won't take too much room in cigarette outlet and won't interfere with anything next to it. Once plugged into the outlet, it has a nice soft blue light to indicate the power is on and also to guide the connection in the dark. I do have to note that usb connection itself is a bit on a tight side which is actually good to hold the cable without falling out. But at the same time pulling on the cable will actually remove the charger itself unless you hold it down with your hand.
The most important test is if it can actually deliver 2 amps per port. A lot of the chargers claim they do, but it only works when one port is plugged in. In this case, I was able to confirm charging my Note 2 at max speed (the same reading I get from my original 2A Samsung wall charger), and I was able to do that while also charging Nexus 7 (HD, 2013 edition) which charges at 1.5A. Although I don't have two Note 2 to verify full 4.2A dual charging capacity, I have a feeling that won't be a problem.
Overall, I found this dual usb car charger to have great performance, solid build, and delivering it's advertised charging capacity without a problem. Covered by 18-months warranty and currently on Amazon for $6.99 (down from original $9.99, need to use code MPOW01CA at checkout) - this is one fantastic value!

Good review. My car has a USB port built into the head unit, and it really isn't meant for charging. My Galaxy S III would just barely stream music via Slacker and hold the same battery percentage. If yoou're getting the same kind of charging capabilities out of this as you do with you wall charger, that's mighty impressive. I think I'll have to put this on my list of general accessories to get.
Hello Vectron, I just checked the amazon link, it's $7.99 now.

Thanks for pointing it out. I noticed they (MPow) constantly run specials on their products (car chargers, speakers, batteries) which gets noted in special offers section with a coupon code.
Perfect review. Might pick this on up.

Do you know the lowest price of a car charger? I found many car chargers which range from $7.99 to $14.99.
This is a review of Bolse 60W (12A) 7-port usb wall charger. http://mybolse.com/product/detail_B00L2SBZ80.html , available on amazon: http://www.amazon.com/Desktop-Technology-Bluetooth-Speakers-Detachable/dp/B00L2SBZ80/
How many smartphones and tablets do you have in your family? A lot, right? How about wireless headphones or speakers, or maybe smartwatch, or activity bracelet, and so on. What does it all mean? You have all these devices requiring a usb charging port. If you are relying on the original single port wall charger that came bundled with your gadget, you will not have enough wall power outlets to cover each device. There is a number of multi-port charging solutions, but so far I haven't found anything in compact footprint and higher than 40W. Apparently Bolse realized that if you factor in all the latest devices that benefit from 2A fast charging and latest iDevices that require 2.4A, you will need more current to keep everybody charging happily at the same time. So they come up with a 7-port compact wall charger that's able to supply 12A of a combined current!!! Here is what I found.
Arrived in environmentally friendly packaging, it had plenty of details about the product as you flip the box around. The most notable details were compact size (approximately 4.3" x 2.6" x 1.2"), 12A of a combined current, and 7 ports featuring new SmartIC technology. This new SmartIC technology is based on a controller chip which detects and optimizes amount of current based on a device you are using. Each of the 7 ports of this charger have this SmartIC technology so you don't have to guess which port to use for your phone or your tablet or even your iPad. In addition to current detection to maximize the charging speed, each port also has over-heating, over-current, and short circuit protection. As a matter of fact, the top of this charger has perforated surface to allow a better cooling of the device. The wall charger itself connects to a power outlet through a provided 5ft cable, and there is also led indicating when charger is powered up.
During my testing I had no issues connecting multiple devices to this charger, and was able to monitor and to confirm all of them charging at their max speed where the only limitation was the usb cable. You should be aware that not every usb cable will be able to provide a maximum amount of current due to a thickness of the wires which play a limiting factor in charging speed. Also, the max combined current can't exceed 12A, so for example, you can't have 7x iPad w/Retina charging simultaneous at the max speed, or 7x Galaxy phones/tablets charging at 2A each at the same time. But still, a combination of 7 USB ports and 12A of shared current is more than enough for any household.
Overall, I was very impressed with a spec of this wall charger and wasn't disappointed with its actual performance. Being able to supply 12A of combined current, providing 7-ports for charging, and equipping each port with SmartIC technology, while being covered under 12-months warranty - definitely a great deal, now offered on Amazon for $35.99.

Great review, I was a bit cautious about buying one of these from Amazon or eBay as I have been 'stung' before by similar cheap Chinese products that fail quickly or are just plain dangerous. So now I intend to buy one based on your recommendation!
Your comment about the USB cables is interesting, I struggle to find a quality USB cable because there never seems to be a proper specification to them when ordering online. It seems to be common assumption that USB cables are all the same. Can you recommend any quality ones?
Usb cable recommendation is always a tough one because most of them are inconsistent in production quality. I used to love monoprice cables, but now you get one good out of two or three. It doesn't really matter if you spend more money since I've seen better performing $1 cables than some $6. Might as well get a bunch of cables and see which one gives you a faster charging speed. You can use something like I reviewed here: http://forum.xda-developers.com/showthread.php?t=2451375 - doesn't tell you the exact reading but rather a relative reading so you can compare to find the one with a faster charging speed.
That's been very helpful. Thanks very much for the info.
