Questions about Multi-Charger + Atra 3-in-1 magnetisches USB Kabel

The manual states under features: "Qualcomm Quick Charge 3.0 is backwards compatible with Quick Charge 2.0 and supports fast charging of compatible Huawei devices"
"Due iSmart charging technology automatically adapts to your devices and maximises charging speed".

So I would give it a try, or ask at a digitec shop if you can test it.
I hope I have helped you with this
