Whether you're constantly on the move or even relaxing at home, your smartphone, tablet, or other gadgets drain their batteries surprisingly fast. That's where a reliable portable power bank comes in—ensuring you stay connected anywhere, anytime. Unsure which one fits your needs? Our expert guide breaks it down.
Key Factor: Focus on Capacity First
There are endless options in sizes, colors, and designs—even customizable power banks. But the real key to a smart choice is capacity.
Measured in milliampere-hours (mAh), a typical iPhone 11 battery holds 3110 mAh, while the Galaxy S10 packs 3400 mAh.
To fully recharge your device from empty, pick a power bank with at least matching capacity. Got a Galaxy Tab with its hefty 7300 mAh battery too? Opt for at least 10,000 mAh to cover both.
Unsure about your device's specs? Check the manufacturer's site under technical details, or simply Google "[your device] battery mAh"—like "iPhone X battery mAh" for quick results.

Higher capacity means more charges, but it also means heavier, bulkier, and pricier units. Balance this with weight, size, design, and budget for the ideal fit.
In short, before buying a power bank, verify your devices' capacities and choose one that fully supports them—in power and portability.
