Top Power Banks of 2025 Revealed

As a frequent traveler across the country with a bag packed full of technology, the challenge of devices running out of power far from an outlet is a familiar one. Thankfully, the evolution of power banks has transformed this issue into a minor inconvenience. Ensuring I charge my power bank before leaving home means I rarely find myself stranded with a dead phone. The variety of power banks available today, from reputable brands like Anker, Belkin, and Mophie, to even Energizer, ensures there's a solution for everyone. Many of these now support Qi wireless charging, adding convenience for those moments when a USB-C cable is forgotten. The key is to choose a power bank with sufficient capacity to keep your devices powered up; a 20,000mAh battery can typically recharge an iPhone twice or a tablet once. For laptop charging, a power bank with at least 45W output is essential, especially for gaming laptops which require even more power.

When searching for a power bank on Amazon, you'll encounter hundreds of options, many from lesser-known brands. While power banks are essentially large batteries and not overly complex, safety and performance can be compromised with low-quality units. Issues like battery swelling and overheating are serious concerns, making it crucial to select from trusted brands. The inclusion of wireless charging in many modern power banks is a bonus, especially when a cable is out of reach.

Choosing the right power bank involves considering capacity and output. A 20,000mAh battery can generally charge an iPhone twice or a tablet once, while laptop charging requires at least 45W output. Having tested numerous power banks, I've honed in on what makes a portable charger exceptional for your travel needs.

What to Look for in a Power Bank

Capacity

Capacity is crucial when choosing a power bank. Measured in milliamp-hours (mAh), a 10,000mAh battery is standard and can typically charge a smartphone three times or more. Keep in mind that some power is lost during transfer, so the actual capacity might be slightly less.

Ports and charging speeds

Chargers vary in their output capabilities, with some supporting standards like Power Delivery (PD) for faster charging. For smartphones, at least 20W is recommended, with 30W being ideal for quick charging. Tablets require a minimum of 30W, while laptops need 45W to 60W to keep up with their power consumption. Consider the charger's input speed as well, as a large capacity with slow input can 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 drain lithium-based batteries fully before recharging. Doing so can 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 as long as they use lithium-ion or lithium metal batteries. They must be in carry-on luggage due to fire risk, and the capacity is generally limited to 100Wh or about 27,000mAh, making standard 10,000mAh chargers acceptable.

How long do power banks last?

Power banks from reputable brands like Anker and Belkin typically last 2 to 4 years. The lifespan can vary based on usage, build quality, and capacity. To extend the life of your power bank, avoid overcharging, store it in a cool, dry place, and charge it fully every three months.
