This is currently the latest appliance manufactured anchor that is on the market only since March 2013. It is a very handy device - in terms of size with a pack of cigarettes compared. The mobile battery pack has enough power to get through times a camping weekend without power. The Astro E4 13,000 has two USB ports, (even simultaneously) with which devices such as smartphones, tablets, and even batteries of e-cigarettes can be loaded mobile. Even Samsung Tablets are hereby charged (as opposed to the anchor with 10,000 mAh). He also charges quickly, provided you load with a power AC adapter on. Many USB power supplies have only 0.7 mAh (thus the battery pack loads extremely slowly - about 20-25 hours), good already 1.0 mAh, but the battery pack even jat a current consumption of up to 1.5 mAh. The original Samsung power supply units of Galaxy Tab 2 7.0, as well as the Note 10.1 has a power output of 2 mAh, which loads the battery pack without any problems. The more mAh, the faster load the battery pack. It does not matter if one power supply has more power, a maximum of 1.5 mAh Only ever recorded. I invite the battery pack with my Samsung USB power adapter and with my Samsung cable (connector S2 / S3 perfectly match the battery pack!) The attached anchor adapter cable are not used by me. Tip from me: I have found me a power supply for the vehicle power supply - and even herewith the anchor can E4 13,000 mAh battery pack be super charged (again, you should ensure there is sufficient mAh of car adapter, then the completely empty Powerpack is also here charged in about 10 hours). Conclusion: newest anchor device, the price is also very good, very good processing (nothing wobbles) and the battery pack stores even over a longer period, the performance - hardly self-discharge - that speaks for good batteries. I, the external battery pack E4 13,000 fully recommend. So I'm also without power always mobile!
