Hauwei adaptive fast charger vs Tattu USB Wall charger. Will too many amps hurt my battery.

[Diven]

I just bought a used Huawei mate 10. I need a car charger and possibly a home charger.

I have my mate 10 charger rated at 5v/2.0 a. I could stick with it but then I wouldn't get the adaptive fast charge.

Huawei does not list the specs on their site for the adaptive charger other than 5v/2.0 a,,, or faster,,,lol. But I've seen pics of the charger and it says also 9v/1.67 a. Assuming that it's not a fake.

Tattu has their I/C system. It charges at 5v/2.4 a per side. Would the 2.4 a be too much for my battery to handle.

Is Tattu's wall charger the same as Huawei's adaptive charging?

What is a faster charge. More amps or volts. I'm confused,,,lol.

Different fast charging methods use different voltage/current combinations, so there isn't a single answer to the "voltage or current" question. According to this XDA article the Huawei system uses lower voltages with higher current, and 5/2.4 would be outside spec. But that was written before the Mate 10 so I don't guarantee they haven't changed it.

If course if the system is designed properly the phone should control charging, in which case attaching a more powerful charger would do no harm but also bring no benefit. Would I trust Huawei and Tattu to work together like that is a different question - remember that the downside of playing safe with a charger is slower charging, while the downside of incompatibility can be a lithium fire.
