General phone with the travel charger, able to do so, as far as possible use of seat-type charger. Retained from the phone manufacturer directly charge mobile phones that function point of view, there should be some technical support. However, damage to the components of such failures on the analysis, usually charging current is too large, over the phone due to the charging circuit of the load, causing the main reasons for such failures: first, mains voltage current instability in many cities in China, in particular the relatively high voltage at night; the second is the poor quality of the battery, or battery power caused by too ruthless. Of mobile phone users, the fast charge current is best used as a temporary or emergency charging method, the use of seat enrich my knowledge as the main charging. As a way even after the failure, nor will it damage the phone itself. If jewelry, keys, or the like beads exposed conductors and the battery electrode contact, these substances may make and complete the circSONY PCGA-BP2NX battery Dell inspiron 1420 battery Dell m1330 battery Dell M1730 battery Dell Inspiron 6400 Battery Dell Inspiron 9200 Battery Dell Inspiron 9400 Battery uit and become very hot, causing injury to persons.
