The $17.59 RavPower 12000 phone charger (75 percent off its $70 list price) boasts a pair of fast-charging USB ports. That means you can charge two devices at once, perfect for sharing a charge during a long-haul flight.
Once fully juiced up, the RavPower 12000 can charge an iPhone 7 more than four times over. The RavPower portable battery can also charge an iPad Mini up to 1.8 times, or a jumbo-sized phone like the Android-powered Samsung Galaxy S7 up to three times.
Weighing in at just shy of 12 ounces and about the size of an iPhone SE, the RavPower 12000 is small enough to slip in a pocket. It also comes with a pair of microUSB charging cables plus a travel pouch.
