Portable cell phone charger features: 
 1: compliance with international safety standards, charging circuit design, with more than a dozen senior IC design engineers and 2,000 square meters related to the automatic clean production workshop. 
 2: The selection of high quality international brands polymer batteries, built-in multi-protection devices, security, high-performance 
 3: Chargers reagent selected grade fire hard plastic material, durable 
 4: Battery-free memory characteristics, charge and discharge, easy to use 
 5: Turn the charger until the charging device, the circuit automatically adjusts the corresponding part of voltage and current strength, it will pause for 2 seconds before the charging voltage regulation and stability, complete protection of mobile phones and other electronic equipment and batteries 
 6: battery charger itself is low (charging time), the voltage is below 2.8V will automatically cut off the charging power supply, to maintain reasonable internal battery charger has a surplus capacity, and keep 3V voltage, the internal battery fully protect the aluminum structure, increase security
