eCase via Amazon offers the Kmashi 10,000mAh MP816 External Battery Pack for $13.99. Coupon code "ME6ADK4L" cuts it to $9.29. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $6.55.) That's slightly under our mention from last month and the lowest total price we've seen for any 10,000mAh battery. (It's a current price low by $8.) It features dual USB ports and four status LEDs.
