Best wireless charging pads under $20

The RavPower Fast Wireless Charger 10W Max with QC 3.0 Adapter is normally $27, but there's an $10 coupon on Amazon that brings it down to $17. That's a great deal for a fast-charging pad that comes with a fast-charging power adapter.

Anker sells a few different basic wireless charging pads that look similar. This model is the latest version (it's "upgraded" to fast-charging) and is only $12. It comes with a Micro-USB cable but no AC adapter. In order to activate fast-charging (7.5W or 10W) you do need a compatible power adapter. Basic adapters tend to be 5W. With one of those adapters, your phone will still charge wirelessly, just not as fast.

Mophie's "Apple-optimized" charging pad retailed for over $50 when it first came out (I use it now). It's now down to $20 for a limited time. This is a 7.5W charger -- the maximum charging speed for iPhones. (Android phones are capable of charging at 10W.)

This 10W (for Android phones) and 7.5W (for iPhones) wireless charging stand was on sale for $11.55 for Black Friday and Cyber Monday, but it's still decent value at $17 (we use it here in the office). On the plus side, you can charge your phone in landscape or portrait mode. Only downside: It includes a USB-C cable but no power adapter. However, the one that came with your phone will work just fine.

This is also available in a 2-pack for $33.

I use this wireless charging pad everyday at work. When it first came out in 2018, it was $50. Now it's down to $33 (new). But if you're willing to get the "renewed" version from Amazon, it's only $10. That's a great deal for a nice charging pad. It only goes up to 7.5W, but that's all the latest iPhones can do. Includes an AC adapter for faster charging.
