Charging this device via USB your device is telling you it’s drawing power from a USB port—whether that’s a wall adapter, a laptop, a power bank, or even your car. But here’s the catch: not all USB ports deliver the same amount of power.
- Standard USB 2.0 port: Delivers up to 0.5A (500mA)
- USB 3.0 port: Up to 0.9A (900mA)
- USB-C Power Delivery (PD): Can deliver up to 100W (20V/5A) for compatible devices
The type of cable data USB you use also matters. Some cables are designed for charging only, while others support both charging and data transfer.
Types of USB Cables: What’s Best for Your Device?
USB-A to Micro-USB
Still common for older Android phones and accessories. Slower charging, but widely available.
USB-A to USB-C
The new standard for most Android devices. Supports faster charging and data transfer.
USB-C to USB-C
The gold standard in 2025. Used for the latest Android phones, tablets, and even laptops. Supports high-speed charging and data.
USB-A to Lightning / USB-C to Lightning
For iPhones and iPads. Apple’s proprietary connector, but USB-C to Lightning supports fast charging.
Pro Tip: Always use a high-quality, certified usb cable for android phone or your specific device. Cheap cables can be slow, unreliable, or even dangerous.
Android Cell Phone Charger: What Makes a Good One?
