Cuktech is best especially you are Xiaomi/Poco users. It's formed by ZMI team that was responsible for legendary Xiaomi 10400 power bank

Out there many versions of cuk tech pb now. I just got 10 plus last 11.11 and it's decent for charging phones with up to 120w (only with Xiaomi/Poco selected models) and laptop up to 65w

If want a bit cheaper maybe just for iPhone then can consider cp13/cp25 or 10 mini

Yes all their current models now with ccc because basically cuk tech is from china with Chinese packaging even tho I bought from laz mall cuk tech official. Since last year all Chinese made power banks now with ccc as mandatory stamp certification

Just need to specify the correct model that with 3c during checkout
