This will almost certainly not be 26000 mAh.

I'm with you on that one aswell.

Common sense and the fact that all these random non-brand powerbanks lie.

What common sense? The cells that go into these can come in this capacity and the only way to test the capacity is to take the cell out of the unit and test it which the majority of reviewers don't do. I'm not saying it isn't false advertising but Ive had 2 brilliant 22,400mha packs for about £14 each.

You can test it without taking it apart.

I bought a ravpower 15000mah from amazon and questioned the capacity the reply follows:
Dear customer,
We understand your concern. Please allow me to explain this issue. Hope it can clarify.
The voltage of a power bank is 3.7v. And to charge a portable device, its output voltage should rise to 5v. As there is a process of boosting the voltage from 3.7v to 5v, some battery juice will lose when charging a device
The average conversion rate of a power bank in the market is around 80%, we can use a formula to calculate the actual output = nominal capacity*3.7v/5v*80%. As the conversion rate of our power bank can reach 86%. We can get the result that the actual output of 15000mAh is 9546mAh.
The one without iSmart logo is the older version. But please rest assured that the performance is the same. Sunvalleytek is our exclusive distributor so all the RAVPower products sold by Sunvalleytek is genuine.
Any additional questions, please do feel free to let us know.
Thank you for your continued support.
Sincerely,
Livia

Clearly a response from someone with either a very basic understanding or being conservative with the truth. Not all power banks use 3.7v, it is more common to use a 3.7v Li-ion cell but some do use 4.2v Li-po. Li-ion are safer but have a lower power density. The efficiency of the voltage conversion will vary a lot between brands and 86% seems very optimistic. The efficiency also varies depending on the discharge current used. You also will never get the full capacity of the cell either due to the protection built into the power bank, the charging circuit will stop the cell charging before 100% is reached to increase the life of the cell and reduce fire risk. You also will never discharge a cell 100% in the device, it will shutoff before to again protect the cell. The only accurate way to measure the cell is to take it out of the device.
