Summary
ESR’s new foldable 3‑in‑1 magnetic charger, highlighted in Time’s Best Innovations of 2025, aims to simplify on‑the‑go power for Apple users. The compact unit folds to fit backpacks or even cargo‑pants pockets and supports iPhone 17/17 Pro, AirPods and Apple Watch in a single platform.
The charger delivers 25 W of MagSafe power, charging an iPhone 17 to 60 % in roughly 30 seconds—about 20 % faster than Apple’s own 25 W MagSafe adapter. A built‑in active‑cooling fan drops surface temperature by 6.5 °F, mitigating heat‑related battery wear, while remaining virtually silent; users can mute it with a dedicated button.
In the video the reviewer demonstrates the fan’s near‑silence, the dedicated AirPods pad, and the flip‑up Apple Watch cradle, all certified “Made for Apple Watch.” The device’s sleek white and black finishes complement the M4 MacBook Pro, and ESR also offers a stationary desk stand and a vent‑mount car charger for broader use cases.
For frequent travelers and remote workers, the ESR charger consolidates three essential power accessories into one portable, fast‑charging, temperature‑controlled hub, potentially reshaping the accessory market and extending device longevity.
