RAVPower Filehub, $28 with code VZYR27KK

Right now, you can save $5 on RAVPower’s Filehub, which is actually two travel-friendly devices in one: A 3,000mAh USB battery pack, and a media streamer that can let you access files on USB flash drives and SD cards wirelessly from your phone or tablet. That’s perfect for, say, watching movies on a plane when your tablet is low on space.
