23rd #USB #TypeC analysis is the +Anker​​ PowerPort+ 5 USB-C charger with USB-PD. [Model A2053111]
tl;dr: EXCELLENT. Overbuilt/over-specced charger. Has IR drop compensation (hooray!). Provides 45W Power Rules compliant USB-PD, not just 30W as printed. But suffers from unadvertised "Split PDO" at 20v, .55 PF could be better.

(Edit 9/3:) IR compensation is within allowable limits, thank you +Benson Leung for pointing out the change!

[PDF of Compliance Checklist for Anker A2053111]

These ended up on my doorstep, so I am analyzing them. This charger overbuilt, under-advertised, and functions great. I'd recommend this as a multiport charger for people with laptops. (Or Apple Type-A iDevices.) Only downside is it's glitchy with the 20v setting and is not particularly environmentally-friendly.

First, the ratings: on the side of the box it only claims 30W USB-PD, with voltages that are PD2.0 compliant. (5/9/15/20 -- 12v got the boot.) The Type-A ports have Apple 2.4A D+/D- signaling. However, if you actually look at the USB-PD signals it sends, it is actually capable of 45W. So you are getting more than you pay for!

Problem is the 20V PDO object is glitchy and isn't advertised until sometime after a device is connected. This means I couldn't run any tests at 20v using my Twinkie PD sniffer. This is called "Split PDO" and is described by +GTrusted​​ in their article on this charger here:

However from +Benson Leung​​'s testing with Dell and Chromebook laptops, this almost doesn't affect charging. The laptop will initially select 5v, say "I could use more", then the charger re-advertises with the 20V object included. The laptop then switches from 5v to 20v. So you might run into some problems with devices (like the Twinkie) that only look for the first advertisement.

This charger has IR drop compensation. (Hooray!) This makes it only the second compliant charger with a female USB-C port I've seen with this technology. This means it boosts voltage output at load to compensate for losses/resistance in the cable. For comparison, the dodocool 30W (port) and Innergie 45W (cabled) are the only other compliant chargers I've seen with this.

This means noncompliant devices like the Nexus 6P that require >4.95v to charge will work great. In fact, for the first time ever, I was able to see the Nexus 6P charge at a full rate of 3000mA in Ampere! It even shot to 3010mA briefly.

(Edit 9/3:) Please see the comments, Benson had pointed out there was a change and this IR drop compensation now within limits. So everything is A-OK!

This comes with a downside. The Anker IR compensation is almost TOO excessive. It boosts voltage using my OEM-quality Scosche 5A cable to 5.25v. That's right on the upper threshold of USB-PD acceptable 5v (+/-5%) voltages. If I were to use a "excellent" quality cord like the j5create 5A JUCX01, which has smaller IR drop, the Anker charger would overshoot voltage to an out-of-tolerance 5.30v.

This isn't as bad as it sounds. A non-USB-PD charger can go to 5.5v-4.0v at 3A load and be compliant. It just means the Anker is ever-so-slightly out of spec for a USB-PD charger, which are held to higher standards. This was probably by design, since cable resistance can only go UP, and I'd agree with their decision.

Finally, the Power Factor on this charger is extremely low. Even with just a Nexus 6P connected (5v/3a), it draws 18.1W/34.4VA at the wall. That a PF of .52 at light load, efficiency 83%.

Power factor isn't exactly efficiency... best way to think about it is it clogs public resources. A hydrogen-powered bus with 1 passenger on it is efficient, but clogs public infrastructure. Similarly a 1970s minivan packed with 12 people is a gas guzzler, but is "efficient" in that it frees up the roads.

Computer power supplies are actually required by law to have a PF of >.9 to free up the electrical grid, using "Power Factor Correction" circuitry (PFC). This circuitry is generally expensive, and optional, so most manufacturers omit it. I just make it a point to point out PFC since these high-power USB-C supplies blur the lines between "computer power supplies" and "wall warts". Helping the environment helps everyone.

All in all this charger is well built, engineered, and forgoing some (potentially big PDO) glitches is a good multiport charger. So this is proof Anker can make good products, if they put their minds to it.

+Nathan K.​, thank you, brother for the wonderful review. You should consider writing newspaper articles (if you don't do that already). You write really well.
andy o
I got this one and the non-PD one. Glad to see it's good, was a little worried after the cables thing. Has anyone checked out the non-PD one that you know of, +Nathan K.?
Hey +Nathan K.. I actually think the allowable range in the USB 3.1, USB 2.0, and the USB PD specifications are all 4.75 to 5.5V now, so the Anker is not out of spec. This was changed with an ECN (Engineering Change Notice) back in 2014.

In a recent USB 3.1 doc bundle, see USB 3.1 ECNs/USB 3.1 ECN VBUS Max Limit.pdf

In fact, looking at the USB_PD_R3_0 V1.0a 20160325 ECN clean markup 20160802.pdf document, Table 7-18, vSafe5V is defined as 4.75 to 5.5V.
I assume that it's OK to use this with Nexus 5X phones? Is it overkill?
andy o
+David Orr​ yes it is. I use it with my N6P and even can charge iOS devices with the USB-C to Lightning cable.
+Benson Leung​ Thank you for the heads up, I've edited the post and added it is all good! That's great news.
+Nathan K. Sure. Just bear in mind that this ECR has been in effect since 2014, so this is not a recent change.
+Nathan K. Thank you for all of the time you have spent testing, researching and reviewing these products, it is greatly appreciated. Could you please clarify what type of USB cable I should pair with this to achieve that elusive full charging current on the Nexus 6P? Thanks again!
+Jeff Steelmon Any good quality and in-spec C-to-C cable (USB 2.0 is ok) should allow you to fast charge from this charger.
andy o
+Nathan K.+Benson Leung​ so if the N6P doesn't get >4.95V will it not charge at all, or does it just not request the 3A, charging at BC1.2 spec?

I've been using the Monoprice Palette 6ft C,C cable and as I've said before I strongly suspect high IR drop, but on the non-PD version of this charger it appears to only charge at not much faster than BC1.2.
+andy o​ The 4.95v value is something I discovered empirically from my tests. It appears to use that as a cutoff for drawing current, apparently via BC1.2. I haven't proven it rigorously as I lack a lab power supply.
I have one of these, and while it works great with my Macbook when connected directly, it won't charge the Macbook if I connect it through the Apple USB-C Digital AV Multiport Adapter. The Apple charger works fine in the same configuration.
Anker support said that they were aware of the issue, and were working on an upgrade, but I can't figure out how to tell if the upgraded version is available.

I used the original lg cable. I don't have any problems with my original charger and the same cable. The Anker was brand new so no debris. I sent it back to Amazon. 
+Lasse O , I remember +Benson Leung once said this could happen if a CC pin was broken off or not connected in the phone. There's some "not good" behavior with the LG OEM chargers that would steamroll over this issue. Does your 5X OEM charger happen to have a model number ending in MCS-N04WD? You can see on the back.
Lasse O
My charger model is MCS-NO4ER. Didn't have any other USB c cable to try with. My phone said "charging rapidly" but it still took 30-45 min longer to charge. The app Ampere listed the max USB current differently everytime I connected to the Anker, but always shows 3000mah when connected to the lg charger. I can see some of your Ampere screenshots shows lower voltages too...
+Lasse O I use a Nexus 6P, so the ADC calibration, lithium ion cells, and the charge controller board may be different. I wouldn't use that as a comparison point, only reference for the same firmware+software+phone.
+Nathan K.
so, is this(A2053111 60W version) still THE A+ wall charger? :) based on review and that you also use it in some of your cable reviews, I guess it is.
Also +andy o asked about smaller one I guess about Anker PowerPort5 USB-C 40W 5-Port A2052111: - Anker USB Type-C 40W 5-Port USB Wall Charger, PowerPort 5 for iPhone 7 / 6s / Plus, iPad Pro / Air 2 / mini, Galaxy S7 / S6 / Edge / Plus, Note 5 / 4, LG, Nexus, HTC and More: Cell Phones & Accessories
if 60W is overkill just for phones, should I go for 40W version? Is that 40W version still "untested"?
andy o
+Madfish M the 60W one actually does up to 45W on the C port via USB-PD, which means 5, 9 and 15V at 3A, and 20V 2.25A. Like +Nathan K.​ says, on the charger it says 15V 2A and 20V 1.5A but apparently that's wrong. The 40W one is not USB-PD and can only do 5V/3A on the C port. Both will charge the N6P, N5X and Pixel at 15W but only the PD version will charge the pixel XL at 18W (9V/2A).
Hi,I'm having some problem with this charger and with 40W version.

tl;dr: is it possible that this 60W and 40W are passing voltage on shield of cables? +Nathan K. if you (or anyone else) are still in possession of this charger, can you please check this.

long: For start, I just realized that(since I needed to use I bought AK-A2053311. I also noticed that also have same model number. So I just hope only difference is EU wall socket.

I used this charger with A8181011(from you're 22nd analysis) cable and by accident it touched my face, I feel something. Then I touched shield(outer part) of C connector with tip of my lip and I'm feeling electricity. Then I tried with few other(C->C and A->C) cables including original nexus5x cable, same thing. Also tried it on few different locations(home, work...), same thing.
When I try same thing with original nexus 5x charger&cable, I don't feel this.Well I feel but much much less than with Anker combination. Wouldn't even notice it unless I'm looking for that.

I currently don't have multimeter next to me so can't measure, but will try to get it.
I you still have this charger and A8181011 Anker cable, can you please check if something is leaking to shield of cable. Some similar problem you had in your 48th analysis.

p.s. if someone thinks specific links should be here, I can post them.
p.p.s. sorry for long post :)
+Madfish M No worries. Long posts are OK. I prefer details. I think what you are talking about is "ground leakage current" something endemic to SwitchModePowerSupplies.

Either that, or there is a fault across the transformer linking the primary and secondary! See this video:

So I'd first use a multimeter to make sure there isn't 220VAC on the shield braid, then I'd check for ground leakage. (I can't quite say how I'd test that though.)
+Madfish M I checked and there is SOME voltage leakage to ground (60VAC) or so but the current is so freaking small it's negligible. Even the Apple 87W has the same voltage -- but at a much less current. I don't have meters sensitive enough to measure it.

If this really bugs you, get the Apple 87W and buy the 3-pin grounding cord to go with it. I've linked it below. It MAY help. - Imgur: The most awesome images on the Internet
Huh +Nathan K.​ man, you are fast :)
It's not that it bugs me much, since I never leave (any)charger connected to wall after I finished charging and no dog around to chew the wire :)
I just wonder if port on phone side (or phone itself) will maybe "wear and tear" more because of this.? As that ground leakage is transfered to phone, right?
It doesn't help that housing of charger is metal :)

Btw, your measurement on Apple's charger is with or without 3-pin cord? I guess without.
Also, you measured it(voltage) shield against gnd pin in wall outlet or? 
+Nathan K. +Madfish M, This is a very real thing, especially in countries with 220V power. See : - Vibration (tingling) sensation on the Mac Book Pro | Official Apple Support Communities

Also :

As Nathan points out, there's an easy remedy for the Mac adapters, switch to the grounded duckhead, and make sure to use a well grounded outlet. When I was in China, I went with my usual 3-prong laptop supplies but the travel adapter I brought with me stripped off the ground pin so all of my metal-body laptops would buzz when I touched them.

Finding a grounded cable for the China plugs helped tremendously.

Unfortunately for the Anker power supplies, since they are 2-prong only, you'll have to think of other more innovative ways of getting them to be grounded. It can be done though. You just have to use your imagination.
+Nathan K. When I was in China I took advantage of the fact that the Anker charger has copious spare Type-A ports and my Chromebooks typically have two Type-C ports.

I used the Chromebook's 45W charger with the China AC plug IEC 60320 C5 cable I bought at an electronics market to make sure the Chromebook was earth-grounded. Then I plugged an A-to-C cable from the Anker to the other Type-C on the Chromebook. The Chromebook would not charge from the Anker charger (since the other charger was more powerful), but it would earth-ground the rest of the ports on the Anker multi-port.

Then whatever I plugged into the Anker's Type-C port (my other Chromebook, for instance) would not buzz.
