Instead, when your device is out of gas, you could just plop it down on a charging surface (maybe built into the kitchen counter) and pick it back up when the charge is done. No cable. No searching for outlets.
But wireless-charging technology is still in its developmental stage, and technical challenges still stand in the way of its working perfectly. For one thing, if other metal objects like pens or coins also sit on the charging surface, the phone of tablet to be charged won’t charge, or they will charge at a very slow rate. Some wireless-charging technologies can charge only one device at a time.
