berly got this phone iphone 8 plus. love this phone, but im worried because i was on 2% battery life and i used a off brand 10amp car charger to charge up up to 23% and i dont know if car chargers do damage to my phone or are safe to use, a guy told me that in can swell up my phone or cause fire.. do you think any damage occurred that i cannot notice internally? someone please give me a serious opinion..
