The Best Cheap Qi Wireless Chargers For Sale on Amazon in 2019

Many of today's smartphones, including iPhones and Samsung Galaxy models, support wireless charging. Basically, a wireless charging device creates a short-distance electromagnetic field that a phone can receive and then convert into electricity for the battery to store.

I doubt that anyone needs a wireless charger, but they can be convenient. For example, if you keep your phone charging on a nightstand, it’s a pain to unplug the USB cable when you're groggy. Wireless charging saves you that effort (but you’ll need to place the phone back in the correct charging position).

Wireless charging used to be slow, but new "fast charge" standards like Qi are a big improvement and one reason why inductive chargers are so popular now. Charging stations come in all shapes and sizes, including stands, pads, docks, mats and in-car models.

Some folks wonder if wireless charging is dangerous. I don't know and I doubt that anyone truly does, but the U.S. National Research Council concluded in 1996 that "No clear convincing evidence exists to show that residential exposures to electric and magnetic fields (EMFs) are a threat to human health." Two decades have passed and nobody has linked inductive charging with cancer. I feel safe.

Here are some of the best-reviewed Qi wireless chargers that have sold for less than $30:
