Top Power Banks for 2025 Revealed

As a frequent traveler across the country with a bag brimming with technology, I've faced the challenge of devices running out of power far from an outlet. Thankfully, the evolution of power banks has transformed this issue into a non-issue for me. With a reliable power bank charged before departure, I can keep my devices powered up no matter where I am.

With countless power banks available on the market from lesser-known brands, selecting the right one can be daunting. While power banks are essentially large batteries and not overly complex, safety and reliability are crucial. You don't want to risk a battery that might swell or overheat. Trusted brands like Anker, Belkin, and Mophie are renowned for their reliable power banks, and now Energizer is also entering the fray. The integration of features like Qi wireless charging is a testament to how these devices have evolved to meet modern needs, adding convenience especially when you forget your USB-C cable.

When choosing a power bank, capacity is key. A 20,000mAh battery pack can typically charge an iPhone twice and a tablet once, while power banks with higher outputs can even charge laptops. For laptops, especially gaming ones, a power bank with at least 45W of output is essential.

Having tested numerous power banks, I've honed my ability to identify the best options for different needs, helping you pick the perfect portable charger for your next journey.

What to Look for in a Power Bank

Capacity

Capacity is the most critical factor when choosing a power bank. Measured in mAh (milliamp-hours), you'll want at least 3,000mAh to double the life of a typical smartphone. Most power banks offer 10,000mAh or more, providing multiple charges on the go. Keep in mind that there's always some power loss during transfer, so you might not get the full stated capacity.

Ports and charging speeds

Chargers vary in their capabilities, with some supporting higher voltages and amperages for faster charging. Standards like Power Delivery (PD) can maximize energy transfer. For quick phone charging, aim for at least 20W, ideally 30W, to match growing battery sizes. For iPads, a minimum of 30W is recommended, while laptops require 45W or 60W to outpace their power consumption.

Consider the power bank's own charging speed as well. A 20,000mAh battery with a slow 5W input will take a long time to recharge.

Power Bank FAQ

Should you drain your power bank before charging it again?

No, it's not necessary to fully drain lithium-based batteries found in power banks. Doing so could damage the battery and reduce its capacity. Charge your power bank before it's completely depleted or every few months if not in use.

Can you bring portable power banks on a plane?

Yes, you can bring power banks on a plane if they use lithium-ion or lithium metal batteries. They must be in your carry-on luggage, not checked bags, due to fire risk. The TSA limits them to 100Wh or around 27,000mAh, so a standard 10,000mAh power bank is generally allowed.

How long do power banks last?

Power banks from reputable brands like Anker and Belkin typically last 2 to 4 years, depending on usage, build quality, and capacity. Cheaper models may vary in longevity. Higher capacity batteries often last longer. To extend the life of your power bank, avoid overcharging, store it in a cool, dry place, and charge it fully every three months.
