The release version still features two USB-C ports, three 15W USB-A ports, and a universal mains outlet (10A max, 1000W rating at 100V, 2,500W at 250V), but the release version features one 65W USB-C and one 45W USB-C port.
The prototype I've been using topped out at 61W.
You can charge up to six devices simultaneously (one of those devices being mains powered).
The Passport III integrates the US, UK, EU & AU plugs into a sleek all-in-one unit, so it can plug into and accept pretty much any plug or socket you encounter (note that it does not alter the voltage of the outlet -- the voltage in that country is the voltage you will get out of the Passport III).
On the safety side, it's built using the care and attention to detail that I expect from a Zendure product. Quality components, a resettable fuse that acts as temperature control, and the charger is built around GaN technology to keep things compact and cool and safe.
