The Mophie Wireless Charging Base and Belkin Boost Up Wireless Charging Pad (both $59) should deliver fast wireless charging to the iPhone X, iPhone 8 and iPhone 8 Plus. However, Apple also revealed that its smartphone lineup will support up to 7.5-watts of fast wireless charging too. Using a non-7.5W wireless charger topped the same iPhone X from 46% to 60% in over 30 minutes, which speaks of marginal gains here and there, but gains nonetheless. However, iPhone X jailbroken actually means that the Apple's latest phone does have vulnerabilities that can be exploited to offer users a jailbreak.
Faster charging is pretty much always a plus, especially when it comes to wireless charging.
Up until iOS 11.1 the Qi-enabled iPhones could charge wirelessly by up to 5W and after 11.2 they can go as high as 7.5W - this was divulged by accessory maker RAVpower.
iOS 11.2 is in public beta right now, and usually a full release isn't far behind. Smartphones like the Samsung Galaxy S8, Galaxy S8+ and Galaxy Note 8 all support the Qi 1.2 standard, which allows for 15W charging.
