I personally used this product almost for 3month, and my experience with syska was very interesting. It is very usefull for train journey and in emergency especially in the season of monsoon because light goes off so many times.
This product is easy to carry, light weight and design is also attractive.The battery life is not so long , but usable, you can charge a mobile of 3000mah almost 3times.I think 3times chargeable powerbank is not so bad.All of us can not buy a high price rank powerbank , so this powerbank appears as a money saver.By the way I think this product should have less price.I cant not rate it as value for money but it is just ok for all. If I say its durability it is also ok because when I was travelling to Kolkata in a train it helped me to charge my mobile almost for 33hr, in this period I charged my for 3 times, this is quite ok.So I can say I liked this experience with this product.
What I felt so irritating with this product is that at the time of connecting charger point to powerbank, it sometimes automatically get disconnected.I don't know why but again try to connect it and get connected again. I think this problems should be solved by the company.I can recommend to buy this product for its durability, excellent battery life and especially for its price that is quite ok for all people.
