Best Portable Chargers and Power Banks: Never Run Out of Battery Again
A reliable power bank is one of those things you don’t think about until you desperately need one. The right one depends on what you’re charging and how long you need to stay off the grid. Here’s how to choose.
Understanding Capacity: mAh Explained
Power bank capacity is measured in milliamp hours (mAh). A typical smartphone battery is around 3,500–5,000 mAh. A 10,000 mAh bank gives you roughly 2 full phone charges; 20,000 mAh gets you 4+. Bigger capacity means more charges but also more weight.
Best for Everyday Phone Charging
For daily carry, a 10,000 mAh bank hits the sweet spot between capacity and portability. Look for at least 18W fast charging output so you’re not waiting forever for your phone to top up.

Best High-Capacity Option
For travel, camping, or multi-device charging, a 20,000–26,800 mAh bank gives you serious reserves. Models with multiple USB-A and USB-C outputs let you charge several devices simultaneously.

Best for Laptops
Charging a laptop requires a power bank with USB-C Power Delivery (PD) output of at least 45W, preferably 65W+. Not all power banks support this — check the specs carefully before buying.
