I have one. It is a 74wh battery, With a .8m apple thunderbolt 3 cable it will charge my 16" Macbook pro by 50% in an hour discharging to zero. Using the apple 96w charger it will recharge the battery to 100% in about 45 minutes. Even with the best charging cable you are only going to get 52wh out of this battery due to energy/heat loss. A 13" Macbook pro has a 58wh battery. You will get less than a full charge from this battery. I have repeated this charge/recharge cycle at least 20 times in the last month. It is consistently repeatable.

The wireless charger on mine will not work through my case but it is an Otterbox Defender. That is pretty much a worst case (pun intended). With the case off, positioning the phone or device is finicky to the point of being painful. It is easier and faster to just plug your phone in.

You can charge multiple devices at the same time but the charge rate reverts to slow on all devices. You are still only going to get 52wh of charge spread out among your connected devices.

I got the early bird on Indiegogo so I only paid $149. For an airline safe battery that gives me an extra 4-5 hours of work time it is worth that to me. I got this solely to recharge my 16" Macbook pro. It does that, so I am happy with the purchase at the price I paid. You can still get this at $149 if you shop around for deals.
