You don't need to take your phone case off your phone to use these chargers.
Brad's Deals Editor Michael,
Get this Aukey 10W Wireless Fast Charger Stand for $12.99 when you apply the code on the product page before heading to checkout at Aukey Direct via Amazon. Shipping will add $5.99, but you can have your order shipped for free using a Prime account or a Prime free trial. These chargers are only sold through Aukey's Amazon store, but this is $4 less than the lowest price they've ever dropped to. They're compatible with any Qi-enabled phone. However, the Fast Charge and Quick Charge features only work with the Galaxy S9/S9+ and the iPhone Xs/Xs MAX and XR. If you have one of those phones, you'll also need to pair the charging pad with the phone's original wall charger. Sales tax is charged in most states.
