It's best to use the specific charger and cable that came with your phone as it's properly matched, but when you are forced to use an alternative, try to find something that has the same amperage rating.

There are fancy electronic measuring tools that can accurately tell you what the output of a charge is or if you have an Android-based smartphone, there's an app called Ampere that's fantastic.

Not only can it tell you the charging and draining data, but it also monitors the temperature and gives you some insight i
