So i know this isn't academic and all but can someone tell me a solution for my portable charger is a mobi free it turns on the light when i plug it in but after 2-3 seconds it turns off i have tried charging the power bank but it turns on the red light meaning that it doesn't need more battery so any ?

Well that means either the manufacturers for the charger didn't make it right or its something wrong with the battery because that has never happened to me. I think you should just get a new charger because I have heard that the MOBI FREE brand isn't that good i would recommend for whatever phone you have just go to eBay  and search for new unused iphone or whatever phone you have because when some people buy a new phone they already have the charger so they sell it online. 

Hay i i wanted to make sure you have a good day today how are you and call not text but something like that
