If you only want a travel phone charger, this is the best one I’ve ever owned:

(I didn’t buy it from Ali Express - it just seems it’s sold out on most other websites.)
Available in black and white.
Small, light, fast charging for iPhones.
The only downside is that it doesn’t work in Switzerland because it has a rectangular base that doesn’t fit into Swiss outlets.

I lost one and immediately bought 3-4 new ones because it seems like they don’t make them anymore.
