If you’ve been holding out for a great deal on a portable battery charger for your iPhone or Android phone, now might be a good time to strike.

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.
