Chargers are of different types as alot of gadgets has their own charger even phones have their own set of chargers. Phone chargers are of five types but these days only three are popular, the other two were old chargers for small phones in the past. Now we just have mainly the USB, Type-c and apple chargers. I have been using USB chargers from the past till now and I have used Type-c once but never used iphone chargers before.
Chargers are always fast when they are new building as they gradually get old, their strength begins to drop gradually and their are chargers that are very strong, even after using them for alot of months their strength still matches with the way it was when it was totally brand new and such chargers are very rare and also quite expensive.
It hurts alot whenever our phone chargers gets bad because it mostly happens unexpectedly, we might want to do something urgent in the midnight and our charger suddenly spoils, the phone battery might be low and even if we have some savings specially for solving emergency problems, we may not be able to purchase a charger that moment because all the stores are locked.
The current charger am using is an itel charger and I ordered it from a shopping platform last year June. It wasn't expensive at all and am glad that the charger is still strong. There are charger heads with three pin and there are some with just two pin just like mine. I only love black chargers, I don't like coloured especially white chargers at all. What about you, how does your charger serve you? I hope your phone charger isn't stressing you at all.
