Evio 8000 mAh Power Bank  (White, Lithium Polymer, for Mobile)

Hey it is very good product .... it is compatible for I phone up to 4S model, its worth buying it..... if you want to buy an I phone data cable means i will cost you around Rs.2000 minimum, but with this product you will get iPhone data cable & other two compatible data cable with Power bank for Rs 1850/- & it is awesome... once we charge full means .. we can charge our phone 4 to 5 time ( Full charge)..... only the thing is data cable is too short to charge the power bank & phone as well...

Good buy for an economical price. I bought it last week and it is working just fine as of now. Although the logo on the power bank is oriented differently but technical working of the product is fine.

Very useful device for reasonable price and 8000MAH is worth buying... just go for it and buy the device, if you commonly travel to remote places where the charging facilities are not available...

A real nice product. Value for money. I hv been using it for over a month and found it quite handy and charges my smart phone without any damage to the battery.

A very good charger that i use to charge my s3 thrice. Takes time to be completely charged but very effective given that most smartphones do not contain charge for a full day. If u are a constant user of net go for it.

Cons-
Heavy
Time for charging completely

Good product till now. It has been 20 days since I received the product and no complaints as of now. Overall worth the amount.

Eventhough product presentation is not good, i feel its worth for what i pay.... Logo on the Flipkart page on the device and Original logo printing has difference... i charged it fully i have use and see... i felt its working good, but need a month time to confirm its peformance.... its really a worth deal otherwise.

Update after Using 2months: Worst to buy, its discharge very fast, over heating... it may damage the mobile phone.... dont know whom to contact for service/repair.
