How Does Wireless Charging Work? A Simple Buyer's Guide
Wireless charging sends power from a charging pad to your device through a magnetic field, so you do not plug in a cable. You place a compatible device on the charger and it starts charging. Here is what to know before choosing one.
The basic idea
A wireless charger contains a coil that creates a magnetic field when powered. Inside a compatible phone, earbud case or watch, a second coil picks up that energy and turns it into electric current for the battery.
Because the two coils need to be close and lined up, placement matters. If the device sits off-center, charging can be slower or may not start.
What your devices need
Not every device supports wireless charging. Check the specifications for your phone, earbuds and smartwatch. Many newer models support it, but some earbud cases and watches need specific chargers.
The charger also needs a power adapter plugged into the wall. Using the adapter recommended in the product listing helps avoid weak or interrupted charging.
Cases and placement tips
Thin plastic or silicone cases normally work fine. Thick cases, metal plates, wallets stuck to the back and some ring holders can get in the way.
Line up the center of the back of your phone with the charging area. If it does not charge, remove the case and try again to find the cause.
Why choose a multi-device stand
If you own a phone, earbuds and a smartwatch, a stand that charges all three saves cables and space. The Foldable 3-in-1 LED Wireless Charging Station does this on one compact, foldable unit.
It also includes an LED light that works as a soft night light, which suits a bedside table.
