A quick scan of the reviews shows that some users reported being able to use their phone after recharging with Mobeego for many hours longer than the "up to 4 hours of extended battery life" advertised. It depends on how they were using their phone, which of course is the same when using the phone's initial charge. For example, one reviewer got 3 hours while using the phone's GPS - a known battery hog.
Another reviewer said he used it while camping. "My phone was at 5% when I plugged this in and my phone charged until it reached 92% and the battery can was dead. This was better than I expected and was able to use my phone the rest of the day until I charged it that night at camp." So it all depends on how the phone is being used.
As for Amazon advertising it for only Apple products, thank you.I don't see mention of Android or Windows phones either. So I issued a correction and notified Amazon that it also works on Android and Windows phones, and included a link. I would imagine that the company has already done this, but just in case.
