The gold mophie Powerstation XL 10000 drops from $69.99 to $29.99 with free shipping at Verizon Wireless. You can also get one in rose gold for $34.99. The lowest price we found for one at any other seller was $51. These power banks have two USB ports, so you can recharge two devices at the same time. The 10,000 mAh battery in them can provide three full recharges to a Samsung Galaxy S9 or an iPhone X. Sales tax is charged in most states.
