Wal-PD604 mobile power products are top lithium-ion batteries with a capacity of 10,000 mA when, and uses synchronous rectification technology, making it higher energy conversion efficiency, which in appearance is the use of one-piece aluminum alloy shell , can effectively protect its internal components, the surface after the grinding process, smooth and mellow feel good. Features: * three USB output interface * Use constant voltage constant current technology, cell phone charger 0 damage fertile PD604 this mobile power products have three USB output interface, are 5V / 2.4A, 5V / 2.1A and 5V / 1A thus meet the different currents of mobile phones and flat-panel charging needs, but it can be done at the same time charging, which greatly reduces the charging time. The mobile power source for handsets also achieve the ultimate protection, constant voltage constant current technology, can charge the phone 0 damage.
