Mophie Launches $150 'Powerstation USB-C XXL' Aimed at New MacBooks

It just doesn't add up.

Many lithium battery pack specs don't seem to add up.

I've seen several games played, like a battery listing 20v XXXmAH, but the XXX capacity is based off the of the 5v of the USB port instead of the 20v listed in the spec. I've seen an extraordinarily high mAH number followed by "pB equivalent"--the actual capacity was printed too, in small fine print on the back, and was a tiny fraction of the big number on the front. And I've seen outright fraud, like a 100,000 mAH USB battery bank for $19 with all reviewers saying it only charges for a few minutes.

It is frustrating because I need real numbers in order to know if a battery will get my CPAP to run through a whole night or not, and it's all a bunch of interpretations and lies.

What you mean? Mah doesnt depend on voltage
1mah means it can produce 1milliamps of current for an Hour
And Watthours Shows Energy stored in the bank
Not sure if that Has anytjing to do with voltage
Cause When you multiply Power*Time you get energy and energy is Energy It doesnt depent on what voltage your charging

It sure does.

milliamp-hours = 1000 × watt-hours / volts

If you have a 100Wh capacity battery, at 5V that would be 20,000 mAh.
Whereas with the same 100Wh capacity battery, at 20V that would be only 5,000 mAh.

Im sorry I were a Bit unclear on that
And I Was wrong about the Mah thing i meant watthours is watthours man...(i was Sure that watthours Doesnt depend on voltage But I was'nt sure wheather Mah depends on voltage or not ,and yeah my bad, it does but the question is how bad is this morphie (so-called19500mah) bank)
Its Like joules ,enegy is energy, but your right Mah is currentxtime which does depend on the voltage...
So If you calculate the morphie 19500Mah bank ...
How much would that? Be something like 15000mah? Its interesting Cause i got ~2ful charges and it only went down one Light on the charge Level Guage(i havent charged he powerbank i just bought it yesterday and it has 50percent battery and Afer charging my 6S plus 2times it's on 25%)
Thnx for help man
Jesus bless!❤️
And sorry for my english man ,obviously im not native

It is 82.536 Wh.

It is 82.536 Wh.

So its 16507.2mah,But i guess if you do the same thing to anker products it will be Lower than What they claim
For example, The 26800mah anker powerbank should'nt have been calculated At 5Volts, cause the highest you can take on an air plane is 100watthours/27000mah(most articles ive Read Use these to as equilevant) and 100watthours At 5V is 20,000mah ...

I dont know man
But it doesnt die ... This Actually feels like 30,000mah ,maybe its more efficient Than My anker/griffin powerbanks...

Bought this for my iPhone X / MacBook Pro finally. I was not impressed by the price so I bought some cheaper options out there, but those are much heavier for the same battery size. This thing managed to limit the weight and size to an acceptable level, with the fabric material it's nice to hold.
