In recent years, Apple has sold numerous wireless chargers made by third-party accessory makers. Belkin and Anker have probably been the most prolific, but there have been others — the most recent of which is the Dutch electronics company Zens.
This week, Apple quietly added the Zens Quattro Wireless Charger Pro 4 to its online store. The multi-device wireless charger has a unique double-decker design, which is unlike anything we’ve seen before.

The Zens Quattro Wireless Charger Pro 4 is a wireless charger with two identical levels, each with two wireless charging pads that support MagsSafe and Qi2. This means that it can wirelessly charger four devices simultaneously.
In total, the charger can dish out 60-watts of power, maxing out at 15-watts per wireless charging pad. This means that it doesn’t which wireless charging pad you place your iPhone on, it’s going to fast-charge at the same speeds.
