Charging MBA with Realme adapter

[Javi74]

Hi.
First of all, sorry about my poor English. It's not my mother tongue.

I've checked the specs of the original MBA power adapter:
- 20 V at 2.5 A.
- 15 V at 2 A.
- 9 V at 3 A.
- 5V at 3 A.

Im thinking about using a different charger, with different specs:
- 5 V at 2 A.
- 10 V at 6,5 A.

What expectations should I have? Will it charge at 5V at 2 A, providing 10 W instead of the 30 that the original power adapter gives?
Or is it dangerous and it could ruin my laptop?

How actually universal are USB-C chargers?

Thank you.

USB-C chargers are generally pretty universal. I would expect it would charge, just more slowly. It shouldn’t damage the laptop unless it is a faulty charger. (I’m not familiar with that particular brand).

At only 10W it might not charge depending on your activity. The SoC can use about 15W by itself. On the other hand, if you leave it overnight it should be fine. Even if it doesn't charge while in use, it will probably reduce the amount of battery used.
