Looking for a nice battery pack to keep your devices charged up while you're away from the outlet? Well the Poweradd Pilot X3 is a great one to pick up. Right now it's on sale for $18.99 if you use promo code - NBX883SL - and it has to be sold by PoweraddDirect, or else the promo code won't work. That will give you $4 off. Which isn't a big amount, but hey a 10,400mAh battery pack for under $20 is nothing to sneeze at. You can pick it up from the link down below.
