The Best Portable Chargers to Keep Your Devices Powered in 2026
A dead phone battery at the worst possible moment is easy to avoid with the right backup power on hand, and that's exactly what the best portable chargers are built for, whether you need a quick top-up or enough capacity to charge a device multiple times over. Here is what to look for and our picks for the best portable chargers for 2026.
What to Look for in Portable Chargers
Not every portable charger is built for the same job, and matching capacity and features to how you'll actually use it makes a real difference.
Battery capacity, measured in mAh, determines how many charges you'll actually get. A 10,000mAh charger typically delivers around two full phone charges, while a 20,000mAh model can handle four or more, and dedicated power stations rated in watt-hours offer enough capacity to run small appliances during an outage.
Charging speed varies significantly between models. Look for a charger that supports fast charging standards like USB Power Delivery (PD) or Quick Charge, rated at 20W or higher, since a slower charger can take considerably longer to refill both your phone and the charger itself.
Built-in cables add real convenience by eliminating the need to carry a separate charging cable, though they also mean you're limited to whatever connector type is built in, usually USB-C, unless the charger includes multiple cable types.
Size and weight come down to how you plan to carry it. A slim, pocket-friendly charger is easy to bring along daily, while a larger, heavier model trades portability for significantly more capacity, which matters more for extended travel or emergency preparedness.
Number of ports and pass-through charging matter if you need to charge multiple devices at once or want to charge the power bank itself while it's simultaneously charging a connected device.

Best for Emergency Backup Power: Jackery Portable Power Station Explorer 300
Jackery's LiFePO4-powered station is a different class of device entirely, offering 292Wh of capacity, enough to run small appliances, charge a laptop repeatedly, or keep essentials powered during an outage, not just top off a phone. Its strong review base and high price reflect genuinely different capability from a standard power bank.

How Much Capacity Do You Actually Need?
Most people who just want a backup charge for their phone during a normal day are well served by a compact 10,000mAh charger, since that's usually enough for two full charges without much added bulk. Frequent travelers or anyone away from an outlet for multiple days should look at 20,000mAh or higher for more charges between recharges. If your goal is emergency preparedness or powering something beyond a phone, like a laptop or small appliance during an outage, a dedicated power station rated in watt-hours is a different category entirely and worth the added size and cost.
Frequently Asked Questions
Can I bring a portable charger on a plane?
Most airlines allow portable chargers in carry-on luggage as long as the battery capacity stays under 100 watt-hours, which covers the vast majority of standard phone power banks, though it's always worth checking your specific airline's policy and never packing one in checked luggage.
How long does a portable charger take to recharge?
This depends on the charger's own capacity and the wattage of the wall adapter you use, but a 10,000mAh charger typically takes around 2 to 4 hours with a fast charger, while a 20,000mAh model can take considerably longer, often 4 to 6 hours or more.
Do portable chargers degrade over time?
Yes, like any lithium battery, a portable charger's maximum capacity gradually decreases after hundreds of charge cycles, though quality chargers are built to retain the majority of their capacity for a few years of regular use. Storing it partially charged rather than fully drained or fully charged when not in use helps extend its lifespan.
Conclusion
For everyday carry and quick top-ups, the INIU 45W Fast Charging Portable Charger remains the most trusted, proven choice among portable chargers. If you need more capacity for travel, the INIU Smallest 20000mAh Power Bank delivers several charges in a remarkably compact size. Anyone focused on emergency preparedness should look at the Jackery Portable Power Station Explorer 300 instead.
