Top Power Banks to Buy in 2025

As a frequent traveler across the country, I'm always on the move with a bag packed full of tech gadgets. The challenge of keeping all my devices charged can be daunting, especially when I'm far from a power outlet. Thankfully, the evolution of power banks has transformed this challenge into a manageable task. By ensuring my power bank is fully charged before I hit the road, I can avoid the inconvenience of a dead phone or tablet during my journeys.

Navigating the sea of power banks available on Amazon can be overwhelming, with countless options from lesser-known brands. While these devices are essentially large batteries and seem straightforward, choosing a subpar model can lead to issues like overheating or swelling. To ensure safety and reliability, sticking with reputable brands like Anker, Belkin, Mophie, and the emerging Energizer is wise. Many of these power banks now support Qi wireless charging, a convenient feature for those who might forget their USB-C cable.

When selecting a power bank, capacity is key. A 20,000mAh battery pack can typically provide about two full charges for an iPhone and one for a tablet. For laptop charging, a power bank with at least 45W of output is necessary, with gaming laptops requiring even more. From my extensive experience with various power banks, I'm here to guide you in choosing the perfect portable charger for your next adventure.

Say goodbye to the hassle of remembering to pack cables with the Belkin Boost Charge Plus 10K, which features built-in five-inch Lightning and USB-C cables. Belkin smartly designed the power bank with slots on either side to tuck away the cables when not in use, keeping everything neat and organized. Despite the integrated cables, the charger remains compact, roughly the size of a smartphone and weighing just half a pound.

The power bank is limited to charging via the two built-in cables, which might require an adapter for less common devices. However, most modern electronics, including the latest iPhones, support USB-C, making this a non-issue for many users. With a 10,000mAh capacity, it's perfect for charging smartphones and some tablets. It delivers up to 18W when charging a single device, but drops to 23W when charging two devices simultaneously. It also supports pass-through charging, allowing you to recharge the power bank while charging a device.

It can fully charge a laptop one or two times, making it perfect for on-the-go professionals.

The downside is its size; at 6.13 inches tall and 1.95 inches thick, it's bulkier than most laptops it charges. Weighing 1.39lbs, it can add considerable weight to your bag. Yet, its utility is undeniable, especially at events like CES where power outlets are scarce, and I need constant power for my work.

Its portability is unmatched, weighing just 0.44lbs and only 0.58 inches thick, making it perfect for any bag.

What to Look for in a Power Bank

Capacity

Capacity is crucial when choosing a portable charger. Measured in milliamp-hours (mAh), a 3,000mAh capacity can double the battery life of most smartphones. Most power banks today offer at least 10,000mAh, providing multiple charges on the go. Remember, some power is lost during transfer, so the actual capacity might be slightly less than stated.

Ports and charging speeds

Different chargers offer varying charging capabilities, with some supporting standards like Power Delivery (PD) for faster charging. For quick phone charging, aim for at least 20W, ideally 30W, to handle larger phone batteries efficiently. iPads require at least 30W, while laptops need 45W or 60W to outpace their power consumption. Consider the charger's input wattage as well, as a slow-charging power bank 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 fully drain lithium-based batteries found in power banks. Doing so can damage the battery and reduce its capacity. Instead, recharge 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, but they must be in your carry-on luggage due to fire risk concerns. The TSA limits them to 100Wh or about 27,000mAh, so standard 10,000mAh chargers are usually fine.

How long do power banks last?

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