Top Power Banks for 2025 Revealed

As someone who travels frequently across the country with a bag brimming with tech, I understand the challenge of keeping devices powered up, especially when far from an outlet. Thankfully, modern power banks have transformed this issue into a non-issue. By ensuring my power bank is fully charged before departure, I rarely find myself stranded with a dead phone.

While these devices are essentially large batteries and seem simple, using a substandard one can lead to serious issues, such as overheating or swelling. It's crucial to choose reputable brands like Anker, Belkin, and Mophie, which are known for their reliable power banks. Energizer is also entering the market, adding to the competition. Many power banks now support Qi wireless charging, which is a fantastic feature, especially if you forget your USB-C cable.

The key is to select a power bank with sufficient capacity to keep your devices running. A 20,000mAh battery pack can typically provide two full charges for an iPhone and one for a tablet. For laptops, especially gaming ones, a power bank with at least 45W of output is essential.

Although I haven't used every power bank listed here, my extensive experience helps me pinpoint what makes a great portable charger for your next trip.

Best Power Bank

Our Top Pick### Belkin Boost Charge Plus 10K

See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output23WPorts1 x USB-C, 1 x LightningSize6.1" x 2.9" x 0.7"Weight0.5lbPROSHas a USB-C and Lightning cable built inCan charge multiple devicesCONSNo additional ports for other devicesWith built-in cables, the Belkin Boost Charge Plus 10K simplifies charging by eliminating the need for additional cords. It features five-inch integrated Lightning and USB-C cables, ensuring you're always ready to charge. Belkin smartly designed the cables to tuck away into slots on either side of the charger, keeping them organized and tangle-free. Despite the cables, it remains compact, similar in size to a smartphone and weighing just half a pound.

While limited to these two cables, the power bank is versatile enough for most users, as USB-C charging is widely supported. Its 10,000mAh capacity can charge smartphones and some tablets, but with a maximum output of 18W per device, it's not ideal for laptops. iPhones can reach 50% charge in under 30 minutes, and the power bank supports simultaneous charging of two devices at a total output of 23W. Pass-through charging is also available, allowing you to recharge the bank while using it.

2. Anker 737 Laptop Charger

Best Power Bank for Charging Laptops

### Anker 737

2This powerful charger ensures your laptop stays powered all day. See it at AmazonProduct SpecificationsCapacity24,000mAhTotal output140WPorts1 x USB-C, 1 x USB-ASize6.13" x 2.15" x 1.95"Weight1.39lbPROSProvides ample wattage for fast chargingFeatures an informational displayCONSIts size is significantLaptops demand more robust charging solutions due to their higher power consumption. The Anker 737, with its 140W total output, meets this need and can even handle some gaming laptops. Its 24,000mAh capacity should fully charge most laptops once or twice.

However, its bulkiness is a notable drawback. At 6.13 inches tall and 1.95 inches thick, it's larger than many laptops it charges, and at 1.39lbs, it adds significant weight to your bag. Despite this, it's invaluable for on-the-go professionals, especially at events like CES, where power outlets are scarce.

3. Charmast Portable Charger

Best Budget Power Bank

### Charmast Portable Charger

The Charmast charger offers a 20,000mAh capacity for half the price, though with a slower 20W output. It's bulkier, at about an inch thick and weighing 0.8lbs, but it's a cost-effective choice for those who can afford slower charging times.

The Anker MagGo, with its Qi2 support, offers 15W charging, nearly as fast as the typical 20W wired fast charging.

Its lightweight and slim design, weighing just 0.44lbs and only 0.58 inches thick, makes it highly portable. However, its 10,000mAh capacity limits it to one or two full iPhone charges. Fortunately, its USB-C port provides quick wired charging as well.

What to Look for in a Power Bank

Capacity

Capacity is the most critical aspect of a power bank, measured in milliamp-hours (mAh). A 3,000mAh capacity is standard for flagship phones, so a 10,000mAh power bank can typically provide three full charges. Remember, some energy is lost during transfer, so you might not get the full stated capacity.

Ports and Charging Speeds

Power banks vary in their charging capabilities, with some supporting standards like Power Delivery (PD) for faster charging. For smartphones, a minimum of 20W output is recommended, while iPads and laptops require at least 30W and 45W, respectively. Consider the charger's input speed as well; a 20,000mAh battery with only 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 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, but only in carry-on luggage due to fire risk concerns. The TSA limits them to 100Wh or about 27,000mAh, so a standard 10,000mAh charger is typically allowed.

How long do power banks last?

The lifespan of a power bank depends on usage, build quality, and capacity. Reputable brands like Anker and Belkin typically last 2 to 4 years, while cheaper models vary. Higher capacity batteries tend to 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.
