Almost bought this on Amazon for $29. Was in Walmart, Baldwin Park, CA, tonight, looking for something else, and saw the posted price of $21. Bargain I thought. When they rang it up, it was $15!!!! This charger is incredible! Charged my Pixel XL and Galaxy Tab, at the same time. Pixel was at 70%, and Galaxy Tab was at 68%. Both charged to 100% in 17 minutes! See attached receipt (erased out credit card info). Please note that the link below only shows web price. Again this is a YMMV, but thats why I attached my receipt. Good luck!
