Traveling across the country with a bag full of tech can be a challenge, especially when devices run out of power away from outlets. Fortunately, modern power banks are both efficient and portable, solving this issue seamlessly. I ensure mine is fully charged before leaving, which usually prevents any power-related stranding during my travels.

The market is flooded with power banks, many from lesser-known brands. While these devices are essentially large batteries and may seem simple, choosing a low-quality option can lead to serious issues, such as overheating or swelling. Established brands like Anker, Belkin, and Mophie are known for their reliable power banks, and even Energizer is making strides in this space. Many of these power banks now support Qi wireless charging, which is a convenient feature if you forget your USB-C cable.
The key is to select a power bank with sufficient capacity to keep your devices powered. A 20,000mAh battery pack typically offers about two full charges for an iPhone and can charge a tablet once. For laptops, you'll need a power bank with at least 45W output, with gaming laptops requiring even more. Having tried numerous power banks, I can help you choose the perfect one for your needs.

Belkin Boost Charge Plus 10K
Best Power Bank
Our Top Pick### Belkin Boost Charge Plus 10K
1This 10,000mAh power bank features built-in cables, eliminating the need to carry them separately. 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 devicesForget the hassle of packing cables; this power bank comes with integrated Lightning and USB-C cables. Belkin's design ensures these cables stay organized, tucking neatly into slots on either side of the charger. Despite the built-in cables, the power bank remains compact, roughly the size of a smartphone and weighing just half a pound.
While limited to these two cables, the power bank is versatile enough for most users, as the latest iPhones and many other devices support USB-C charging. The 10,000mAh capacity is ample for smartphones and some tablets, with a maximum output of 18W for single-device charging. It supports simultaneous charging of two devices at a reduced total output of 23W and offers pass-through charging for recharging the power bank while using it.
Anker 737 Laptop Charger
Best Power Bank for Charging Laptops
### Anker 737
2This powerful charger ensures your laptop remains operational throughout the day. See it at AmazonProduct SpecificationsCapacity24,000mAhTotal output140WPorts1 x USB-C, 1 x USB-ASize6.13" x 2.15" x 1.95"Weight1.39lbPROSHigh wattage for fast chargingInformational displayCONSSignificant sizeLaptops demand more power than phones or tablets, making the Anker 737 an ideal choice with its 140W total output. This capacity is sufficient for most laptops and some gaming models, supported by a 24,000mAh battery that can fully charge laptops once or twice.
The main drawback is its size; at 6.13 inches tall and 1.95 inches thick, it's larger than many laptops. Weighing 1.39lbs, it adds considerable weight to your bag. Nonetheless, its reliability is invaluable for working on the go, especially in scenarios like CES, where power outlets are scarce.
Charmast Portable Charger
Best Budget Power Bank

With a 20,000mAh capacity, it can charge your phone multiple times, though its output is limited to 20W. This is still suitable for fast charging but not as fast as premium models.
Resembling the Belkin Boost Charge Plus 10K, the Charmast is thicker and heavier, at about 1-inch thick and 0.8lbs. While it may charge your phone in 1.5 hours instead of one, the lower price makes it an attractive option.

What to Look for in a Power Bank
Capacity
Capacity is crucial when choosing a power bank. Measured in milliamp-hours (mAh), you'll want at least 3,000mAh to double your phone's battery life. Most power banks today offer 10,000mAh or more, providing multiple charges on the go. Keep in mind that some power is lost during transfer, so you won't get the full capacity.
Ports and charging speeds
Different chargers offer varying charging speeds, with some supporting standards like Power Delivery (PD). Compare the charger's output capabilities with your device's supported charging speeds. For quick phone charging, aim for at least 20W, but 30W is ideal for larger batteries. iPads require at least 30W, while laptops need 45W or 60W. Also, consider the charger's input speed, as larger capacities take longer to recharge if the input is low.
Power Bank FAQ
Should you drain your power bank before charging it again?
No, it's not necessary to fully drain lithium-based batteries 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 unused.
Can you bring portable power banks on a plane?
Yes, you can bring power banks on planes, but they must be in carry-on luggage due to fire risk. The TSA limits them to 100Wh or about 27,000mAh, so a standard 10,000mAh charger is generally fine.
How long do power banks last?
Power bank longevity varies based on usage, quality, and capacity. Reputable brands like Anker and Belkin typically last 2 to 4 years, while cheaper models may vary. Higher-capacity batteries often last longer. To extend life, avoid overcharging, store in a cool, dry place, and charge fully every three months.
