The mobile phone can be loaded by approximately 110-120%, so it's enough for me from completely to survive a day with a long train ride and many energy-sapping apps.
The 2400mAh course not agree, otherwise the phone would have full charging at least 1.5 times let (Iphone: 1440mAh), but this is normal for inflation and external battery power bank providers (is one of the key selling points and bad refutable by Otto normal).
But there is enough for me and doing what it should, I'm happy and excited me less than the 1m cable from Apple, if I have to pull the power strip on my bed when I want to call the evening.
