EDIT:
I just read one of the critical reviews. I've pasted it below for reference. The problem is they are not taking into account the actual energy capacity of the battery. They are simply assuming mAh can be converted between his MacBook and the battery pack and the iPad which is incorrect. The batteries in the MacBook are 3S which means they have a nominal voltage of something like 11V while these battery packs are 3.6-3.7v. So at least for this one, it is simply the user thinking they're smarter than they are. I mean, does he really think a $35 battery pack that is the size of two smartphones will be able to charge his laptop 7 times?? He must be lying when he claims he has a 20k mAh battery that can charge his macbook pro 4 times. That would break the laws of physics and would also not make sense why laptop manufacturers don't just put bigger batteries in their laptops if they can be so cheap and so small.
Obviously the real issue is your phone. I don't lose more than 1-2% over night on a modern device.

For reference I have a 20,000 mAh pack and it charges my MacBook Pro 4 times fully, with enough left for my iPhone and iPad before dying.
So, like many other batteries on this site, 30,000 mAh is not truthful.
*I bought a battery a few months ago that claimed it was 26,800 mAh, and when I hounded the seller because I knew that was not possible, he immediately took the product down and told me it was actually 8000 mAh.
You have to be very careful when buying, as sellers will put whatever they want in the description, and that stinks. All 3 of these are going back.
