Is 45W enough to charge a laptop?

Only for light ones. A 45W USB-C laptop like a MacBook Air will charge, but slowly under load. Gaming laptops and most 65W-and-up models need a bigger charger.

Can I charge two devices at once?

Yes, one on USB-C and one on USB-A. The 45W is split between them, so each device charges slower than it would alone.

Does it support USB-C Power Delivery?

The listing only names Quick Charge 3.0, which is a USB-A standard. Check the USB-C port's PD profile before relying on it for fast charging a phone or laptop.

Will it work in Europe?

The 12-230V input covers European voltage. You still need a plug adapter for the outlet shape; check that the prongs are not fixed to a US-only plug.

Is GaN worth it over a regular charger?

GaN lets a 45W charger run smaller and cooler. If size and heat matter for travel, it is worth it; otherwise a standard brick does the same job.

What comes in the box?

The charger only. No USB-C or USB-A cable is listed, so plan on using your own.

Our take on the MIRO D2 GaN 1C1A 45W Fast Charging Wall Charger

The MIRO D2 is a compact GaN wall charger with one USB-C and one USB-A port, rated 45W total with Quick Charge 3.0 on the older USB-A side. GaN internals keep it smaller and cooler than a same-wattage silicon brick, and the 12-230V input covers US and European outlets. It suits charging a phone or tablet fast and topping up a second device at the same time. No price was given for this listing, so check the current best price against the 45W single-port chargers it competes with.
