Who doesn't love wireless charging? It's a super-convenient way to power up your Apple kit without the hassle of cables. However, one of the biggest drawbacks of wireless is the heat generated, which can slow down charging speeds and potentially damage your battery over time. 

The ESR 3-in-1 MagSafe Charger with CryoBoost aims to address this issue with a proprietary cooling system that keeps your devices at optimal temperatures during charging. This might sound like snake oil from other brands, but ESR is a well-established player in the mobile accessories market, with a strong reputation for quality, affordable products, so we definitely thought it was worth giving a go.

Belkin Boost Charge Pro 3-in-1 Wireless Charging Stand with MagSafe

The Belkin Boost Charge Pro 3-in-1 Wireless Charging Stand with MagSafe is Apple-approved and sold on the Apple website. Like the ESR charger above, it offers fast charging speeds for iPhones (25W) and AirPods, and Apple Watch (5W). However, there's no Cryoboost tech and it's also more expensive. So the only possible reasons to buy it are that you care about it being Apple-approved, or you prefer the look of the design.
