For example, I have never had to worry about the mileage of my car. But if I fill my fuel tank and run out of fuel within 3 days without doing anything out of the ordinary with the car, I shall immediately begin to question its fuel consumption. That is what has happened to me with my power bank. I began to use the Anker PowerCore II Slim 10000 mAh portable battery in June 2019. Some months ago, I noticed that I would plug it into the power mains to charge for hours and end up with two LED lights instead of four. Four LED lights indicate a full charge. If I unplugged it and plugged it back in one or two times, it would then charge fully. That behaviour was odd. And it began to get worse. Now, the power bank barely charges beyond one LED light. Drats. I used another portable battery before this one, an Oraimo Fast Charging 10000mAh power bank, and it was still in active use by its new owner, and giving no such issues. What made it even more interesting was that this Anker unit was a more expensive device than the Oraimo. In other words, my newer, more expensive Anker PowerCore II Slim 10000 mAh portable battery was misbehaving about a year into use, when an older, less expensive model still worked flawlessly.
So, how long can you use a power bank?
To answer this question, a good power bank should serve you well for nothing less than two years. In many cases, portable batteries work well into 3 or 4 years. If a power bank is misbehaving after a year of use, there is a problem with it. What made this sad is that Anker is known for their quality power banks.
Fixing the problem: Resetting the Anker PowerCore II
I ran a Google search to see if other Anker PowerCore II users were experiencing the same problem and found a few complaints like that. And I also found out that the device could be reset. Belkieve it or not, I had no idea that one could reset a power bank. Anyway, this was new info, and I used it. I performed a reset of my PowerCore II and plugged it to the mains to charge. Voila! Problem solved. My power bank was charging as good as new again.
How to reset Anker PowerCore II Power bank
If you are already itching to find out what the reset process is like, here it is. The power bank comes wiith a short USB charging cable in the sales pack. To reset it, use this charging cable to create a loop – plug both its end iinto the two respective ports of the Anker – leaving it in for about 3 to 5 seconds. Some others say to leave it for up to 10 seconds. I did 5 seconds and pulled out the cable. PS: I have no way of verifying that the above reset information is officially recommended by Anker, but it worked for me. If you use iit, you do so at your own risk. If possible, contact your device manufacturer for assistance. I later also found a suggestion that pressing and holding the Power button for 30 seconds will reset it too. That sounds safer than the charging cable loop.
How to use a power bank the right way
As with all electronic items, a power bank can be misused and abused, leading to problems. If you want your power bank to function properly and last as long as it should, you need to observe certain rules.
Shopping for a new power bank?
If you are shopping for a new portable battery, here are some tips. Personally, I am not a fan of bulky gadgets. This is why I love the slim profile of the Anker PowerCore II. In my books, a power bank should not leave a bulge when in your trouser pocket. Anker PowerCore 10000 PD Plus is a newer model and a credible alternative to my current model, but it does not have that slim profile. Still, that just might be how you like your portable battery, so check it out. If you can still find it in the market, the Soda SP60 6000 mAh portable battery performed well in our testing and usage. Finding it now is the real problem, as Soda Mobile has vanished from the market. There’s this cute itel power bank that I have reviewed and used, but it didn’t last either. It began to fail after some months of use. The good thing is that there are many portable battery products out there to pick from. Brands that I have used include: Oraimo, Xaomi, Anker, and OnePlus. There are others as well, so look out for them.
Is there anything to avoid when buying a power bank?
Yes! Those portable batteries that offer humongous battery capacity at ridiculously low prices? Stay. Away. From. Them. They are usually substandard products made by obscure manufacturers. Those ones will develop trouble quickly and die on you just as fast.
Conclusion
In closing, I am glad that my Anker PowerCore II is functioning well now and I do not have to replace it yet. Yay! Hopefully, I can squeeze 2 to 3 years out of it. But now, you also know what to expect from a good power bank in terms of life span. You also know the right way to use a power bank.
