Introduction

Anker's line of PowerCore portable chargers can charge any USB device, and leverage high-capacity battery cells that make it possible for some of their devices to hold enough energy to power up your iPhone 6s up to seven times over before you'll need to recharge it. Having one of these devices handy can help ensure you won't have to worry about your portable electronics running out of steam while in an important meeting or out with friends. Common problems with the PowerCore line of chargers are typically associated with powering up the charger, charging connected devices, not understanding the meaning of the LED lights on the device, and issue with dirt and other debris getting into the USB ports.

PowerCore Won't Charge

  • If possible, use either the Micro USB cable that came with the Anker PowerCore charger to power it back up, or a certified third-party cable. If you're using a non-certified, third-party cable, the Micro USB connector may fit, but it may not power up your portable charger. Additionally, third-party cables can also potentially do a great deal of harm to your device, as they don't go through the required testing that certified cables go through.
  • Ensure the outlet you're connected to is working. If possible, try connecting another device to that outlet to see if it works.
  • If you're portable PowerCore charger is not charging quickly, try using another wall charger. A 2 amp charger will fully recharge your device over 12 hours. A higher-output charger will power up your device faster.
  • If you've noticed that the PowerCore doesn't charge while you have devices connected to it that are charging, that's because it's not possible to do that. This is not good for the battery, and as a result Anker doesn't make it possible for the user to do that.

Connected Devices Not Charging

  • If the situation is one where devices connected to your Anker PowerCore won't charge at all, ensure that the charging cable is firmly connected to both the portable charger and the device you're attempting to charge. Additionally, try using a different USB cable in the event there may be issues with the cable you currently have connected.
  • If the connected devices aren't charging quickly enough and you have multiple devices connected, remember that when multiple devices are connected the charger is outputting the same amount of power, but it is splitting it between the two devices, so it will take twice as long.

How often do you have to plug in your phone for charging over the course of a day?

What do the lights on my PowerCore mean?

There are a couple of different reasons the LED lights on your Anker PowerCore charger could be flashing:

  1. If your portable Anker charger is connected via the Micro USB cable to a wall outlet and charging, a percentage of the LED lights on the device will light up, illustrating the percentage of the device that is charged and ready for use. All of the lights on the portable charger will go dark when the device achieves a full charge.
  2. If there are devices connected to your PowerCore charger, you'll notice that the LED display shows you a percentage that illustrates how much of the battery is available for use.

Environmental Elements

While the Anker PowerCore is a fairly rugged portable charger as a result of a strong outer shell, dirt, sand, and other environmental elements can get lodged in either the USB ports or the Micro USB charger, and cause a variety of issues associated with charging. The unwanted debris may result in sporadic charging of connected devices, or sporadic powering up of your charger itself. Additionally, over time, the build-up of dirt and debris can do serious damage to both your portable charger and connected cables, potentially resulting in both not working further down the line. As a result, it's important to keep your Anker charger away from elements as best as possible.

In the event that you do see visible dirt and debris inside of your charger, do not attempt to remove it using a paper clip, knife, or any other sharp object, as those can also damage your device. Try using a Q-Tip or other soft object to try and clean out any debris.

Questions & Answers

  • My ANKER external battery's lights flash randomly when it is charging. I have noticed the battery itself feel a little convex on the top. Do you know why this is happening?

    I've never encountered this with my charger, but I wonder how old it is and how long you're leaving it plugged in for. I wonder if it's getting too hot for too long. If you're leaving it plugged in, I would unplug it when you're not using it. The only problem is that the damage may be done. You may want to reach out to Anker support to see what the random blinking light means.

      I tried to boost my car with Anker Model 1501. It appeared to be fully charged but would not perform. In fact, it went completely dead after. I wall charged it until all four lights went on. Now the LCD light will not go on and it will not even charge my phone. I had a horrible thought - did I connect the wrong cables to my cat battery? Did that put my charger to death? After an alternate boost my car works fine. Thankfully!

      I currently am using the Anker Powercore 20100mAh and using it to charge my Pixel 2 phone. It can charge when still on a table but the slightest movement (even picking up the phone) will stop it from charging. The cord in all the way in on both ends. Also, even when it does charge, it charges very, very slowly.

      Fingers crossed. We've got a few of them, and haven't run into any issues yet.

      Yes, this ultimately should be fine. However, it's generally not a good idea to leave cables plugged in that you're not using. It does introduce a fire hazard, and probably results in a few extra cents on your electric bill.

      I charged it up once and it worked perfectly, since then it hasn't charged back up at all. Had to return it because it isn't supposed to be a 1 use product. Tried switching up cables and outlets etc etc

      Owned two ankers the 21600 and the 10000. Very dissapointed first one the charging brick at first was fine after about a month of use one of the usb's stopped working and it would always discharge constantly even if nothing was plugged in, became useless. That one at least came with a wall charger, but now the wall charger doesn't even work at turbo 3 speed it just short circuits and sparks. The 10000 have owned for a week now I charge it all the way up till all the dots are full and the lights turn off completely. Plug it in to charge first 2 dots are gone within 3 minutes of charging my phone, maybe I get half a charge out of it and my phone is 3000 mah. Just a shame they have good specs but terrible quality control.

      Well it's called this anker earbuds are reliable. I've had my earphones for a month into weeks. I only use my earphones when I work out so at most for an hour or 5 times a week. The earphones are supposed to be waterproof because I sweat a lot. I charge my earphones for two days straight and still no response. So I guess I live in a learn because I will not be buying any more products from anker. That your phone should've lasted more than a month and two weeks. I try to hold out from buying Dre beats but I guess I'll be purchasing those ear phones now.

      Used my Anker 20100 only a few times. Tried to charge it up last night and only one bar. Wow, so disappointing. Got Anker quiet keyboard and mouse bluetooth combo as well and after a few use started to get noisy like a regular keyboard. What do you know. First time it's on me. Second, well, it's time to move to a different brand.

      Hi Max

      Last Thursday, I got the Anker Astro e1 5200 Ah. I charged it until it got to two bars. Then I tested it out by charging my iPod touch. It did okay till the second light was out. Then I charged the Anker and left it for a few days and now the lights won't come on. Helppppp!! I don't know what to do!!!

      I have the same problem, I have the Powercore 20100,, when you charge it the led starts at the 4th one as if it's 75% charged but it actually is charging... Tried all the chargers in the house+- no luck. It's a shame I had to change brand because of this.

      Anyone encounter this? After 4 or 5 few charges Anker Astro E1 5200mAh my iPhone6 battery keep shows 100% most of the day - late in the day starts slowly to go down and when about 75%, suddenly goes dead. Turn the power back on back up for several seconds it shows 75% and then goes dead again. Wonder if this has anything to do with the charger of is a iPhone issues.

      I was given an Anker 20100 in November of 2016, and have used it 5 times to charge my phone since December. Today is my first time charging it and after four hours of being plugged in with its original charging cord, the first led is still blinking and the charge hasn't increased at all.

      I am going to give it a few more hours before I give up entirely.

      Hi Joe,

      First, sorry to hear about the troubles you're having with your Anker Astro. We have a few different Anker chargers, and I've always had good luck with them. With some batteries you have to charge them fairly regularly to cycle them and keep them going. It sounds like you used it sparingly, which in the world of chargers can actually be a detriment. I would recommend calling Anker with your issue to see what happens.

      Best,

      Max

      I purchased a brand new unopened Anker Astro E1 5200mAh portable charger on Sept 2015 for $20.

      I used it three times to charge my Samsung cell phone for about 20 minutes. I carry it just for emergencies.

      But 16 months later now the charger won't charge. It has one blue button which just blinks. I'm using the USB cord the charger came with but I've tried numerous adapters and usb cords. I think the charger is defective but since I didn't purchase it from AnkerDirect there is no warranty. It's an Anker Astro E1 5200mAh Ultra Compact Portable Charger External Battery Power.Model: A1211 SN:O5DEGL

      It didn't slowly not take a charge; it just stopped charging one day. But I only used it three times. I think this is last time I ever buy anything Anker.
