20000mAh portable charger for $(removed)

This is the best price I've seen on a 20000mAh USB portable charger. It's $(removed), but if you use the promotion code Y4DFT2KK at checkout you can buy it for $(removed) (at least it was $(removed) the last time I checked.) I bring a 20000mAh charger when I travel and it keeps my iPhone 6 Plus fully charged for a few days with heavy use.
