Resolved: Anker battery pack users - a question

Evening all,

I've got an Anker PowerCore 20000 (http://www.androidheadlines.com/201...core-20000-quick-charge-3-0-battery-pack.html), and if you fully charge it, unplug it and then replug it in, it proceeds to charge again for between 5-15 minutes.

Anker sent a replacement for the one which does this, but the replacement also does this.

Is this strange charging behaviour common in Anker products, especially in the PowerCore range? Does it suggest an issue with the batteries?

Any info would be much appreciated - I get the impression the CS rep, whilst very nice to send out a replacement, didn't actually know about the issue and just saw I'd flagged a complaint and wanted to placate me, rather than solve the issue.

Hugh

A lot of charging circuitry will naturally allow this to happen. Just don't do it. When it says it's full un-plug it, why do you feel the need to play around with it?

In phones you will have software based battery stats which decide when a battery hits 100% based on it's voltage and it decides that's it. Hardware only based chargers are calibrated to stop charging simply when the battery reaches a certain voltage and stops increasing IIRC, and as soon as you disconnect the charger the batteries immediately lose some voltage, and because there is no software to remember that the battery has just been fully charged to 100%, which means when you reconnect they will try to charge again.

How do you know it's charging? Have you put a USB power meter on it to see if it's drawing any amps?

I have the same power bank, and while the lights do light up if you disconnect then reconnect after a full charge, it's not drawing any amps. It looks like it's just balancing the cells in the pack if it's already charged - which is what the last 5-15mins of a charge cycle should do anyway.

Sounds like you're trying to find an issue where there isn't one.

I was given the exact same last month. This one and my older 13000mAh Anker does this. This is quite common though, especially with AA and AAA chargers in that re-inserting the batteries will invoke the ETA meter for a few mins. Also camera batteries (Canon at least).
 
Thank you all for your comments and for sharing your experiences.

I'd like to emphasise that I mentioned it to Anker, and they were the ones who essentially confirmed it was an issue by sending out a replacement.

I was not sure it was an issue, hence asking Anker. Sounds like their CS rep doesn't know it's perfectly normal behaviour, so that explains it.

Thank you all again for the suggestions as to why it happens, and for confirming that it has yet to be indicative of any issues for any of you.

I have the same Anker battery and I've put it through all sorts of pain. Charging on the move while on a motorbike, charging other devices while it is charging both on a bike and on the mains. It has never let me down. When out on a bike trip I just try and keep it as charged as possible. It charges iPad, iPhone and 3 GoPro batteries at once on the go and it just keeps going.

Super bit of kit.
 
Basically the charger once unplugges has no reference frame, so once you plug it in itll assume there is some charging needs done and begins until it detects overvoltage/another peak.

Once its done unplug and use, your overcharging it which is not a good thing to do, lots of chargers are capable of this although any that are worth their salt *should* prevent you doing it enough to blow up the battery, but do you want to take that chance?

As mentioned mobile phones and laptops are "always on" and employ a range of tools to prevent any damage by overcharging as a phone going nuclear is bad for pr, just ask samsung.
 
I have a USB battery pack from another manufacturer and it always did exactly the same thing as your's is, nothing strange about it as others have said; its like every time you plug it back in it takes 15 mins analysis to determine it doesn't need any more charge
