Can Anker ever go wrong? Love the dim LED and charge indicator, Working Voltage Boost, and Power Filtering
By Spencer Smith
The first thing I noticed after taking the charger out of its protective sleeve, was the heft. This charger really must have a decent transformer inside of it. I have 4 port chargers that weigh less than this. Whether the weight is a transformer or heat sink its a win win in a charger.
The finish is glossy white with a matte grey front fascia. Luckily the white does not show fingerprints and the grey wont show scratches from the plugging of USB ends. The 2 prong wall 120V plug has a nice click when folding and unfolding and allows the charger to be plugged in either way. The charger is also no wider than a fruit named company's standard brick charger.
LED indicator light:
Quite the nice feature as a lot of phones charge faster with the screen off. As soon as a (likely) shunt resistor shows lack of voltage on the output, the light will return to blue indicating a full charge.
Even with both ports under a (2+2) = 4A load, the charger only got slightly warm to the touch. The efficiency is great in this bad boy.
Quite the nifty feature here, I have a resistive load tester and on a 1A load the charger output 5.08V but when a 2A load was present which will increase voltage drop in a cable, the output voltage was boosted to 5.15 volts to compensate. Very cool.
It also seems that very clean power is output by this charger. I don't have an oscilloscope but large capacitance almost always show a clean output. I was able to unplug the charger and have my output monitor stay lit for almost 5 seconds. Quite a few millifarads here.
Most importantly, the output:
iPad Air 2 with screen on playing video: 1.87A
iPad Air 2 with screen off : 1.77A
Samsung Note 4 with screen on: : 1.15A
Samsung Note 4 with screen off : 1.29A
From an electrical engineer's perspective, this is THE charger for anyone with an Apple product
Please remember this charger DOES NOT support Qualcomm's "Quick Charge" protocol

Potency x 2
Hey there fellow nerds and non-nerds!
I used a Drok USB Ammeter/Voltmeter...
DROK USB 2.0 Digital Multimeter, Ammeter Voltmeter Capacitance & Watt Meter, 7 Modes Multi Tester, DC 3A 12V Amp Voltage Power Meter, Charging System Tester, Fast Charging and Data Sync Dual USB Ports
... to compare this Anker 2-Port USB charger against three other 5V USB chargers, tested back-to-back, while under the heavy load of an iPad 3 showing its battery at a 14% state of charge.
The Anker outperformed the other three chargers, maintaining a slightly higher than 5V output (at 5.16V) - which helps to overcome a 5V battery's internal resistance, especially as it approaches 100% charge - topping it off - while essentially matching the current delivered by the Apple iPad 3 charger (2.02 Amps vs. 2.03 Amps), but offering two USB ports instead of only one. Nice!
Note that simultaneously charging an iPhone 6s with the Anker’s 2nd USB port had no impact on the measurements taken while charging the iPad 3 on the 1st port. In other words, the Anker's two USB ports appear to be independent - one port is not "weakened" in either amps or volts when the other port is also in use. Nice!

Caution Fire hazard!
Warning this charger is a fire hazard. It was working ok when I received it couple of weeks ago. But today my kids complained that they could hear something and they saw a spark from the charger. Wife confirmed it when she tried to test it herself and she also saw.the spark when she unplugged it when she heard the noise.
I went to read the other reviews and I am not the only one having the sparks issues. This needs to be recalled.
