Chargers

USB-A and USB-C chargers are different in 2 main ways.

Design: USB-A features pin connectors and has a thin, rectangular cross-section, and can only be connected in one direction. USB-C, on the other hand, has an oblong-shaped plug that is smaller, more rounded, symmetrical, and can be inserted in any direction.

Performance: The USB-C standard is a big improvement on USB-A, which enables higher power capacity and much faster data transfer, which is why it is preferred by most major phone brands.

If the connectors match, generally you can use a different charger for your phone charging with no issues, though the charging speed may vary depending on the charger’s power wattage. That's why multi-port chargers and even wireless chargers are becoming more popular. However, it’s also recommended to use certified quality chargers from your phone's manufacturer or from an established company like Anker to ensure safe charging.

It depends. If you charge your phone using a certified quality charger with the same connectors as your original charger, there should be no effect on the phone. However, your phone or battery may be damaged or potentially affected when charged with cheap off-brand chargers if they were not made to official charging and safety standards.

It’s not advised to leave chargers plugged into the wall when not in use, even though energy experts say that phone chargers only use electricity when they’re charging. However, long USB cables from these USB wall chargers still pose safety risks, especially for families with kids, elders, or pets who could be tripped.
