cocoa169 5 I bought this charger as second charger for my lenovo laptop because I'm doing 50% home office and I often forget to bring my charger to office.The size is very compact, smaller than my laptop original 45W charger even though with higher power. I compared it with a 65W charger from my personal Dell laptop (2020), this charger is twice smaller.I read that some other GaN charger has got some thermal issues and they became very hot while charging, I was a little bit afraid about it however no issue with this charger, it get a little bit hot but just as my original 45W charger, I can touch it without any issue, the temperature is comfortable.Using it with a 100W usb C cable, it is charging my laptop faster than my original charger so I guess the 65W are there.I highly recommend it, it's also cheaper than the other competitors.
