very minimal, sturdy, and compact charger, charges the nothing phone 2 very quickly (slightly raises temperature but at normal levels). I recommend it

Very good charger with a very small footprint, which charges the mobile phone exactly as its specifications claim. It does not get very hot, while its small size makes it suitable for a charger that one can carry in their bag without thinking about it.

I don't know if it actually delivers up to 45W, but I have done various charges on an iPhone 15 Plus. The phone charges fully in about 95 minutes (from 20% to 100%) with the following time data (for iPhone 15 Plus with a 4383mAh battery). The charging was done with an ANKER 1.8m cable.

The first 50% (from 20% to 68%) in about 30 minutes.
From 68% to 87% in another 30 minutes.
And from 87% to 100% in the remaining 35 minutes.

In conclusion, in approximately the first 40 minutes, it charges from 20% to 80%, which is very satisfactory if you want to charge a phone and have limited time available. I believe it supports fast charging.
