These powerful Dual Port USB Wall Chargers by RAVPower offer optimized charging speeds at up to 17W, and today you can pick up a pair at Amazon for just $12.99 when you clip the coupon on its product page and enter promo code HHUX8P7R during checkout. That'll score you two wall chargers for only $6.50 apiece, though the promo code will only work on the black version of this product.

Featuring iSmart 2.0 technology, these dual-port USB wall chargers provide an optimized charge for whatever's plugged in, and each one is capable of charging two devices at the same time. They've been engineered to safeguard your devices against overheating, overvoltage, overcurrent, and short-circuiting. Despite how compact they already are, these chargers also feature foldable prongs which will help them take up even less space while packed away.
