If a company lies this much about capacity quality is pretty much guaranteed to be shit, avoid like the plague.

I don't have any idea about the quality of this one but all power banks are like that.

can someone help me understand the output amperage.
Can you use all outputs simultaneously, and get the max rated amperage for each out put?

can this theoritcally output 6amp?

Numbers look good... But how long it will hold the charge? I have bought a few powerbank that failed on me less than a year of use.

But i cannot comment on this particular one. I never used it. Just be aware that can be an issue within short time frame.

They're not BSing on the capacity. There is just an inefficency between what the power bank has and how much it transfers to your phone.

Even if you buy a 20000mah Anker or other reputable power bank, it will not charge your 4000mah phone 5 times.

Got one...
hoping it's enough to keep an LED projector like this, https://www.amazon.ca/dp/B0759HMFFN
powered for outdoor use for at least a full movie

edit: I don't think it's going to work but i will keep it for something else anyway. Thought it had AC power outlet on it.

What? That's not how battery capacities are measured. Sorry bud but 20800mah is supposed to be 20800, those numbers are not to include resistance on unique charging applications.

A quick rule of thumb is to assume that the real world capacity of your powerbank is 2/3 of the theoretical capacity mentioned on the package. So for a quality 10000 mAH powerbank it will be about 6600 mAH and for a 26800 mah powerbank it will be about 18000 mAH.
