The Four Device Portable Backup Battery

This is the backup power bank that can recharge four devices at once. Ideal for keeping mobile devices powered up away from home, it has a 1-amp USB port for charging a smartphone, two 2.1-amp USB ports for charging tablets, and an integrated 90-watt AC outlet for connecting low-voltage electronics such as a laptop. Individually, the rechargeable 25,200 mAh lithium-ion polymer battery can replenish an iPhone eight times or a Samsung Galaxy Tab 2 1/2 times before the device itself needs recharging. A row of LED lights indicates the remaining battery level, and the USB ports automatically shut off when the connected phones or tablets are fully charged to conserve the bank's power. Lightweight and portable, the device is ideal for camping trips and other travel and is approved for in-flight use. Recharges in 20 hours with included AC adapter. 6" L x 5 1/2" W x 1" D (1 3/4 lbs.).
