I examined a 9,000,000mAh battery pack from eBay – here is my shopping for recommendation

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, would not it? Properly, you already know what they are saying.

A reader introduced this itemizing to my consideration, questioning the validity of such daring claims. Though I harbored vital doubts, I made a decision to analyze additional. All within the identify of science, in fact.

First, let’s put that declare of 9 million mAh into perspective. The $150 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 would must spend over $35,000 on 375 PowerCore 24K energy banks, and that is definitely not one thing I would wish to carry round—nor wouldn’t it match within the palm of my hand.

So, I ordered one in all these purportedly massive-capacity energy banks and waited just a few days for supply.

Here is what I acquired: 

Surprisingly, the packaging lacked any daring claims concerning the promised, but unrealistic, capability. Moreover, the plethora of typos on the bundle did not encourage confidence within the product.

Additionally: Lastly, a MagSafe battery pack that does not seem like a brick (and it expenses fast, too)

The facility financial institution’s useless state 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.

Possibly 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 wish to use my trusty metallic spudger, so as an alternative, I turned to a safer plastic instrument.

Then, to each my shock and shock, the facility financial institution blinked into life for just a few seconds whereas I used to be poking inside it.

After just a little little bit of power — 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 did this account for why it wasn’t working, nevertheless it additionally introduced a hazard of short-circuiting and even fireplace.

Additionally: My favourite USB-C accent of all time simply received a magnetic improve (and it is 30% off)

I took a better take a look at the batteries. 

Additionally: One of the best MagSafe battery packs of 2024: Professional examined and reviewed

They had been all no-name 18650 lithium-ion cells, and I measured their capability to be about 2,000 mAh. I think these could also be outdated “recycled” cells or probably seconds, as I would count on the capability of even an affordable 18650 cell to be about 2,300 mAh. This implies the complete pack had a capability of 6,000 mAh, a far cry from the 9,000,000 mAh that it marketed.

Now, to be sincere, that is finally what I used to be anticipating. 

Exaggerated claims dupe consumers into shopping for poor-quality energy banks constructed incompetently from low cost components. When you’re searching for an affordable energy financial institution, I would say throw an additional ten bucks into the acquisition and get your self this Baseus 10000mAh for $20. That means, you are getting a superb high quality energy financial institution that delivers what it guarantees, offers you a number of years of service, and will not be a possible fireplace hazard.
