An influence financial institution boasting an enormous capability of 9 million milliamp hours (mAh) that matches within the palm of your hand, all for just a bit over $10, sounds too good to be true, does not it? Effectively, what they are saying.

First, let’s put that declare of 9 million mAh into perspective. The Anker PowerCore 24K has a capability of 24,000 mAh, and it is fairly a large energy financial institution, weighing in at 1.3 kilos. To attain a capability of 9 million mAh, I might have to spend over $35,000 on 375 PowerCore 24K energy banks, and that is definitely not one thing I might need to carry round—nor would it not match within the palm of my hand.
So, I went forward and ordered considered one of these purportedly massive-capacity energy banks and waited just a few days for it to be delivered.
This is what I obtained:
Surprisingly, the packaging lacked any daring claims in regards to the promised, but unrealistic, capability. Moreover, the plethora of typos on the bundle did not encourage confidence within the product.
The ability financial institution being lifeless on arrival additionally did not enhance my first impressions. Even worse, regardless of my makes an attempt to cost it, nothing labored. It was fully unresponsive out of the field.
Perhaps I might fall again on the “guarantee.” I doubt it.
It was time to roll the cube and take it aside to see what was inside. At this level, my cash was on much more disappointment. Since I used to be prying into an influence financial institution, I did not need to use my trusty steel spudger, so as a substitute turned to a safer plastic instrument.
Then, to each my shock and shock, the ability financial institution blinked into life for just a few seconds whereas I used to be poking inside it.
After a bit of little bit of pressure — typically an unreasonable quantity — the case popped open and I might see what the issue was. One of many wires from the battery was disconnected. Not solely does this account for why it wasn’t working, but it surely additionally introduced a hazard of short-circuiting and even fireplace.

I took a better have a look at the batteries.
They have been all no-name 18650 lithium ion cells, and I measured the capability to be about 2,000 mAh. I believe these could also be previous “recycled” cells or probably seconds, as I might count on the capability of even an inexpensive 18650 cell to be about 2,300 mAh. This implies all the pack had a capability of 6,000 mAh, a far cry certainly from the 9,000,000 mAh that it marketed.
Now, to be trustworthy, that is finally what I used to be anticipating.
Exaggerated claims are getting used to dupe consumers into shopping for poor high quality energy banks constructed poorly from low-cost components. In case you’re in search of an inexpensive energy financial institution, I might say throw an additional ten bucks into the acquisition and get your self this Baseus 10000mAh for $20. That method, you are getting high quality energy financial institution that delivers what it guarantees, gives you a number of years of service, and will not be a possible fireplace hazard.
