The external battery lasts for just over an iPhone battery charge and is thus prima suitable to get more done to provide enough energy. I test the battery for a few months now and I am very excited and can only recommend it.
When I asked a question to the support, I was this immediately answered and solved my problem immediately.
Conclusion: If I could forgive 10 stars, I would do so. The value for money is just great!
