The official Samsung Galaxy S4 wireless charging kit is expensive and doesn’t work with most Galaxy S4 cases, but a $27 Galaxy S4 wireless charging receiver is slim enough to slide inside the existing Galaxy S4 back so you can use wireless charging and cases.
With a little investigating I found a Galaxy S4 wireless charging adapter that connects inside the back of my Galaxy S4 without adding any noticeable bulk. This is a Qi wireless charging receiver that retails for just $27 on Newegg and is easy to install.
Once installed the Samsung Galaxy S4 wirelessly charges on any Qi wireless charger, including the Nexus 4 wireless charger.
For the past two weeks I’ve used the cheap Galaxy S4 wireless charger to charge my Samsung Galaxy S4 without plugging in.
This Samsung Galaxy S4 wireless charging receiver is designed to connect to the same contacts the official Galaxy S4 wireless charging back does. Users can remove a small sticker to attach the Galaxy S4 wireless charger to the battery, or users can rely on the pressure of the case to hold it in place. I did not use the sticker during my review, and like that there is enough pressure to keep it in place, in case I need to switch batteries down the line.
This accessory works with the Nexus 4 wireless charger, which keeps the phone at an angle to see notifications. Users can also pick up a different Qi wireless charger from a local carrier store or online. As long as it has a Qi logo it should work.
Installing the Galaxy S4 wireless charging receiver is as simple as removing the back, lining up the contacts and snapping the back of the Galaxy S4 in place. This back is tighter than without, and the middle bulges a bit, but the Galaxy S4 still fits in most cases.
Placing the Galaxy S4 on a Qi wireless charger will immediately start the charging process, and if unlocked it will show a pop up confirmation. Unlike some devices, this Qi wireless charger is not picky about where it needs to sit to charge. The Galaxy S4 sits on the slanted Nexus 4 wireless charger without slipping off, a common complaint with the Nexus 4.
This Galaxy S4 wireless charging receiver is not as fast as plugging in to a USB port, but it is perfect for charging up at my desk or charging overnight.
Newegg sells the Galaxy S4 wireless charger for $27 and users can purchase a Qi charger for around $40 to $60.
