For me, I’d never use quick charge on Chinese marketed devices… I don’t trust the safety mechanism…
As for the charger, the Hi10 comes with a charger inside the package. I received an Euro plug, so I had to buy a US one… VC Lemon decided not to send me a charger and aliexpress can’t do anything about it, or so they told me.
For charging, max amp for Hi10 is rated at 2A for 5 volts. If you try to use 5.3V rated at 2A, it’ll cause very slow charge, I tried it.
