Something to keep in mind for those who would take this flying, it has 111WH printed on the battery which is more than the 100wh limit for carry on before you are technically supposed to get airline approval for. Of course YMMV on whether TSA will actually check closely, but potentially more hassle to bring something this large when flying.
That's true for most of these battery packs. I'd like to know by what metric though. Did they actually open it up to see the capacity of the cells they use? If so, that would be misleading and false advertising. However, if they simply tried to charge their device and got less total energy than expected, that is not necessarily false advertising since all battery packs lose some energy in the charging process.

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.
I've never seen one that stays on...Aukey, Ravpower, Samsung, etc.

Obviously the real issue is your phone. I don't lose more than 1-2% over night on a modern device.

Sent back two as they did they same issue. Once my phone was charged, the battery turns off and then my phone discharges. I'd wake-up with 87% sometimes. Even my cheapo chargers keep my phone at 100% until they give it up.
I've owned many battery packs over the years and every single one turns itself to prevent extra battery drain, not a deal killer at all for me.

The mophie battery cases stay always on ready to charge unless you turn them off manually so it usually charges the phone keeping it at 100% until battery depletes. I've encountered same with other battery packs as well (it's one thing for the phone to cut off the charging and not enable it again unless re plugged or it reaches certain level but I also agree on phone loosing more than 4-5% while on standby at night which would indicate battery is outlived its cycles and needs to be replaced), there are exceptions if it's being used as hotspot for example.

This guy is losing a whopping 13% over night. I've owned Android and Apple phones, never heard of such a thing. If their phone isn't ancient, I suspect a rogue app like Facebook or Instagram is killing the battery.

There are people in the other threads for this model that have reported that the actual battery capacity is lower than 30k mAh. Does anyone have any recent first-hand experience with this or testing one of these?
