My previous tests have shown that the delivery and performance of the RavPower panels are better than that of the armature.
Both come in plain cardboard packaging and therefore see at first sight noble, stable and very good processed. The RavPower has also not yet come up 4 small, matching color, carabiner while the product description. So a nice little extra about which I was very happy!
If it now goes to the performance of the two is clearly the RavPower front! Above all, the low light performance is insanely good! In the morning at 6:50 in high fog (see photo) in Rostock it has already started my Power Bank to charge! This gets the device from Anker not out (comparison). In good sunshine it loads my Samsung Galaxy S5 in about 90 min (2,800 mAh) in direct charge with suboptimal orientation (hanging on the window like on the photo to view it) on! So there is still much potential there.
Next advantage over the anchor are the two small, single charging sockets that allow the large battery bank in set in the storage compartment and close! At anchor it's a great female adhered firmly even in the equipment compartment. This ugly marks is emerging on the outside and the battery bank does not fit in the storage compartment.
The Power Bank together with the solar panel allow to load me for a week and my S5 My Gear Fit exclusively with solar power. We had both good, sunny weather rich, as well as bad weather sun arm. So I'm in good spirits for the holidays :).
Fazi: The RavPower 15W Solar Charger is a very strong buy recommendation for all who need not do without battery-powered devices that can be loaded via USB.
This also applies to radios, flashlights and what I know are powered by AA batteries for example, (is the perfect charger for example the NiteCore UM10)
