External Batteries and Power Banks for Mobile Phones

External batteries, or power banks, provide essential backup power for mobile phones during travel, long work days or outdoor activities. They vary in capacity, charging speed and port options so you can pick a model that meets your charging routines and device needs.

Key features to compare

Capacity is measured in milliamp hours (mAh) and indicates how many full charges you can expect. Fast-charging technologies and multiple output ports let you power phones and accessories quickly. Lightweight power banks are ideal for pockets, while higher-capacity units suit multi-day trips or charging tablets.

Shopping tips

• Ensure the output voltage and amperage match your phone’s requirements for safe charging.
• Consider the size-to-capacity ratio if you need portability over maximum power.
• Look for safety features like overcharge protection, temperature control and sturdy casing.
