Syska X110 is a usless power bank. This product is taking about 10-12 hours to full charge.
I have only charged my 3300 mAh mobile once and this power bank drained completely. This is very bad experience with Syska.
Mi/Intex is quite good compare to this. After writing this review I am returning this product to Amazon. Also the total capacity of 11000 mAh is fake. It may be 7500 - 8000 mAh.
Hence, I recommend you to buy the power bank of lower capacity and avoid the Syska X110 mAh. You will be feel cheated after using this product.
