Chargers

There are 3 types of cable connectors that are used for charging phones.

USB-C Charging Cables: This is the most commonly used charging cable, designed to work with all the latest Android phones, and a wide range of tablets, laptops, and more.

Lightning Charging Cables: The Lightning connector is used exclusively with Apple devices, though not all of them. Some older iPhone models (before iPhone 15) still use a Lightning connector, while most iPad chargers and MacBook chargers now use USB-C. A Lightning cable is also needed for charging certain AirPods models.

Micro USB Charging Cables: The Micro USB cable is now virtually obsolete. In the past it was the main charging method for phones, small items like toys, and early wireless headphones.

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. From USB-C to USB-C cables to USB-A to USB-C options, Anker delivers reliable charging solutions for all your devices.

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 and power adapters 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 or power adapters if they were not made to official charging and safety standards.

It’s not advised to leave power adapters or 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.

No, a 45W charger isn’t too much for modern phones, and most phones today regulate how much power they accept. For instance, an iPhone 16 typically caps at 30W, while some Android devices can take 45W or more. Anker's phone chargers adjust automatically to match safe levels.

Most smartphones only need one full charge per day from the USB charger. Heavy users, such as gamers or professionals relying on video calls, may need more top-ups. Frequent small charges are fine, as modern lithium-ion batteries don’t require full discharges like older models.

For iPhone chargers, 20W or higher is ideal for fast charging. For modern Android phones, many support 25W-65W or higher charging. Anker's 30W to 100W or higher USB-C chargers with multiple ports cover most smartphones safely while offering flexibility for tablets or smaller laptops.
