RIP Anker PowerCore+ December 2015 – June 2016, July 1, 2016
By HEITZIE –
Verified Purchase(What’s this?)
This review is from: Anker PowerCore+ Mini, 3350mAh Lipstick-Sized Portable Charger (3rd Generation, Premium Aluminum Power Bank), One of The Most Compact External Batteries (Wireless Phone Accessory)
We are gathered here today to celebrate the life of our Anker PowerCore+. We received it in December with such joy however, it passed away by June.
Our Anker was there every time our iPhone’s battery indicator hit below 10%. It was always there, ready to charge. For those seven months, it was one of the best friends a guy could ever have. And boy, did it charge until that fateful day during the last week in June.
I noticed my phone was near dead and so I hooked up my trusty Anker and went about my day. When I looked at my phone about an hour later, I noticed it wasn’t charging. I thought that maybe it was the cable. It had to have been the cable. Please be the cable! So, I switched it out but it wasn’t. The Anker had no response… and neither did I. #sadface
Anker is survived by his older brother (also a PowerCore+), who was purchased in September and is still going strong.
We will probably purchase another one because, you know… $10 bucks. So what, right?
Three stars because of battery life otherwise, four.
Anker contacted me and replaced the PowerCore by sending me a new one. Added one star for customer service awesomeness.

Hi, I’m the instruction manual they do not send you, August 25, 2015
By jim –
So yeah, how do I know if the unit itself is charging? A yellow light flashes until it is fully charged.How do I know if my device is charging? A steady green light will show until it is finished.What does the flashing green light mean? It means your charger battery level has dropped below that where it is of use and needs recharged.What does it mean when you don’t get instructions with a new product?It means you waste time looking for them.Fully charged this will bring my HTC EVO 4G LTE up from grave to full pretty close to twice.It will charge a iempire 5s grave to full twice with a bit left over.So why are they so secretive about what the operations functions are?Oh wait, it’s because I’m old. Turns out everyone already knew what those lights meant.

Full Teardown! Not All Batteries Are Created Equal!, November 25, 2015
By The Lone Consumerist –
Power Teardown! Not All Batteries Are Created Equal
***NOTE***This review contains technical observations which I have reported to Anker. Although they have responded to some of them, they have not yet addressed all of my questions. This review will be updated as answers to these questions come in.
Curious about the build quality and what’s inside? Me too, and I destroyed a battery so you don’t have to, and at full price! Overall, Anker’s build quality these days is pretty gosh darn good. Machined aluminum with an anodized finish, and tasteful silk-screening that complements the look and feel of the product. The battery I opened was verified to contain a high quality Panasonic-Sanyo NCR18650BF Lithium Ion cell, which is one of the finest cells available on the market today. Anker has clearly put a great deal of work into creating a fantastic product at a fantastic price. Unfortunately, I observed a number of inconsistencies in both order fulfillment and product performance, which I believe Anker will work to resolve ASAP, at which time I will update this review accordingly.
It is important to note that the battery industry is chock-full of snake oil, shams, and scams. Even with the difficulties that I observed, I am convinced that Anker provides products of better quality and consistency than most (if not all) of the competition as any “problems” that Anker may have are generally much worse with other vendors I’ve worked with in the past.
– Solid, Handsome Industrial Design– Extremely Compact, No Wasted Space Observed During Teardown– Premium Panasonic-Sanyo NCR18650BF Cells Inside – Finest in the Industry– Elegant and Intuitive Usage– Super-fast, Super-friendly Support with 18 Month Warranty – One of the Longest in the Industry– A.M.A.Z.I.N.G. Price! – 9.99USD at Time of Review for PowerCore+ Mini in Black
– Inconsistent Fulfillment, Frequent Product Updates/Changes May Result in Order Errors and Old Product– Inconsistent Performance of Internal DC Boost Converter Between Batteries, Affects Output Current and Capacity, Actual Available Capacity Varies Between 8.5Wh and 9.5Wh.– Possible Inconsistent Quality Control – Based on my numbers Anker deemed 2 out of 4 batteries to be possibly defective and shipped replacements (not arrived at time of this writing).– Some Revisions May Be Prone to Overheating and Loss of Efficiency
IMPORTANT!!! DO NOT USE CHEAP, THIN, OR LONG USB CABLES WITH EXTERNAL BATTERIES. YOU WILL WASTE UP TO 40% OF YOUR POWER!

I’m a bit of a voltnut. I care about the stuff that most people don’t. When it comes to batteries, I want every watt-second I can squeeze out of a cell. Unfortunately, the battery industry is full of lies, treachery, and deceit. Manufacturers are incentivized to fib here and there because now everyone shops by the numbers. People expect the numbers to be highly accurate, and don’t realize how complicated modern batteries can be, how often vendors lie about specifications, and how often cells are counterfeit. I’ve become so jaded over the years that I now expect most vendors to lie until proven otherwise. That’s why when I saw Anker advertise a 3350mAh USB battery for 9.99USD including shipping, I assumed it was too good to be true. It wasn’t until I saw Anker advertise its “Premium Panasonic Cells” that I became truly curious and decided to not only buy some batteries, but resigned to tearing one of them apart in the name of science!
For load-testing the batteries I am using a Maynuo M9712C Programmable DC Electronic Load. When I needed a power source I used a Rigol DP832A Programmable DC Power Supply, and verification of voltage readings was done using a Rigol DM3068 6.5 Digit Digital Multimeter.
In order to minimize power loss in the USB cable during whole product testing I custom-built an extra-short USB cable using 22AWG conductors, meaning that all of my numbers will be best-case scenarios for each of the batteries I tested. Real-world numbers will vary wildly depending on the type, length, and quality of cable used (more on that later).
So without further ado, let’s get to it!
Anker generally uses Amazon’s fulfillment for almost all of their products, which is smart as it offloads a great deal of…
