I'm using the Baseus cable with the wattage reading and I can confirm with you the rate is quite similar to yours. I noticed it was 41W for a long time until 80% when it dropped to 30 then at 90 it stayed at about 18-19W until full. I did not notice the device getting too warm to touch maybe because I had the keyboard cover on.It's nice that it's charging quickly but I'm a little concern over the temperature. It's about as warm or warmer than a Switch after gaming for a good 2~3 hours (not the heat at the exhaust vent, just touching the back cover). It charge really quick though, from 20~85% is under an hour!
Yes, I am using a USB-C power meter. The weird part is that is charging constantly just under 40W (about 37~39W). I can start charging from under 20%, under 50% or above 60% but it will still charge at the rate of a little under 40W. Why I said it's weird is because from what I found on the internet, if the charger and cable couldn't hit the 45W (10V@4.5A) requirement then it will default to the next level of 30W (or 20W, I can't really remember). I know the power meter will grab some juice, but up to 5W difference? That's quite a bit. Currently waiting for a second power meter to arrive so I can cross reference the results.
Any chance I can trouble any of you who can do 45W charging and have a power meter can help to test and share your finding please? Thanks! :3
I doubt the reader will draw up to 5W and I think the figures you obtained is fairly accurate. I would assume the differences between our readings would be the ambient temperature and the equipment.
From my understanding, as the battery capacity is much larger than phones, they can "absorb" charge at faster rates for longer than say a 5000maH battery.
Also with PPS, the charging profile isn't 10V 4.5A. It is a dynamic range between 3.3-11V up to 4.05A so technically 45W isn't accurate (max 44.55W). I never seen the cable read close to 45W before. Max I got was 41W.
