Apple's 20W USB-C wall charger costs $19. But there are plenty of arguably better alternatives, including Baseus' 40W Dual USB-C Fast Charger, which is down to $19.59 when you clip the instant 30%-off coupon on its product page at Amazon. Its list price is $28 (the white version costs $1 more), so you're saving $8 and essentially getting twice the charging capacity of Apple's charger.

I haven't tried this particular Baseus charger but have used others and haven't had an issue with any of them. I've tested and like its new 65W flat charger, which features a USB-C and USB-A port and is also a good deal at around $36. Baseus says this model is powered by the latest fifth-generation GaN (Gallium Nitride) technology. That technology allows for the charger to be smaller and not heat up as much while delivering more power.

This charger's maximum output is 40 watts, which is more than enough to charge a MacBook Air, or you can use the dual ports to charge two devices at the same time (each port would deliver 20 watts in that configuration). No cable is included but most new smartphones come with a charging cable and the latest iPhones include a USB-C to Lighting cable that would allow you to fast charge your iPhone with a wall charger like this.
