First impressions can be a MB Pro Retina hanging off and load a fully charged guter-. Even iPad and iPhone are not a problem. I especially like that you can charge the Power Bank with a 40W solar panel. As I said, that was the first impression. As the long-term efficiency will turn out, I now can not say. Edit (after a few charges), 04/12/2015 I now can find out the following: The fully charged Power Bank coped well 3 hours Operating the MacBook Pro 15 Retina (streaming over WLAN, which, as in some fully loaded recommended) while operating an Ipad including charging from 50 to 100% (also streaming. WLAN) and has still stood at 15%. Even recharging via a 40W solar panel works extremely satisfactory: When it is charging in direct sunlight, the display of at least 10% in an hour you can lt with a charge expected in not so good conditions (partially Thick clouds) with around 5%. in the hour. Clouds do not prevent loading, it's just slower. All in all, the XTPower MP-50000 Power Bank an admittedly expensive, but very worthwhile investment if you want to extend the hours without power. If the product also holds now even longer, even more so.
