Anker 737 some questions, caffe2go

[Ricotta Elmar]

hello guys, something random

 

i have bought this anker 737 gan

but there a  few things that noticed now that it have a display,

 

1. i have a ugreen 100w gan charger, i charge my anker 737 with it , i use the battery it's own cable witch suppose to handle the load but on display i see it reach max 88w and no other devices connected,

2. i have 2 mobile nespresso devices "caffe2go"

    they don't charge with a usb-c to usb-c cable for some reason,

    i have to use usb-a to usb-c,

    what i noticed is realy wierd,

    they have a wierd charge behavior i think ?

    what i tried sounds realy odd ,

    when i charged them both at same, 

    one of them charge with its own cable usb-c to usb-a 2.0 at +/- 10w

    the other one charge with a usb-c to usb-a 3.x adapter and a usb-a to usb-c 3.x cable and charge at +/- 17.9w

    i also tried a usb-a to usb-c 3.x cable and it charge at 12w O.o?

    so basicly i get double the charge speed by using adapters O.o?

3. when i only plug in the usb-c to usb-a 3.x adapter the charger for some reason activated and draw 0.1w O.o

4. one plus 8t charge with with max 10w,  it suppose to handle 65w but no mather what port it wont change, so basicly their advertising is kinda false that they support fast charge on every device,

5. my samsung galaxy s9+  also charge at max 10w no mather what i do,

6, my ipad pro and steam deck charge at +/- 35w,

 

i think the gan chip needs some tuning
