works well charging a wide range of battery type. You can also change the charging rate so you can charge quickly or slowly if you want to preserve the life of your Rechargeable batteries.

Very good 3 different charger cables can be used. So when you loose your normal cable find a i-phone cable or another make & they work bout time someone made this charging method. Recommend 100%
