The Intex 10000 mah power bank has a very good start in the beginning but after using it for a few months it slowed down in charging .At first it used to take 7 to 8 hours to charge completely but now it takes only 6 to 7 hours .This shows that efficiency is declining day by day .
Now talking about its looks it is very thick and also very heavy. It also consists of a torch which might help you somewhere .But you cannot expect a power bank to last long if you are continuously using it everyday .
Advice :- Please avoid use of power banks when you are at home like while playing games and all .This will maintain the efficiency of power bank for a long time .So whenever possible try to use your charger unless it’s very urgent to use your power bank.
