This battery pack is very good and served its purpose fully. The processing is very valuable and the integrated flashlight feature is very convenient. Charging time and capacity of RAVPower in my opinion top. With a load I can my Galaxy Tab2 and my Galaxy S3 and S4 several times Load (tablet and mobile phone or S3 and S4 simultaneously). The charge status indicator (blue LED) is helpful to know about the existing capacity of the battery notification. In short, the device is top and gets a strong buy recommendation!
