A quick search on Amazon reveals hundreds of power banks from various brands, many of which you might not recognize. While these devices are essentially large batteries and relatively simple, opting for an unreliable one can lead to serious issues like overheating or swelling. Trusted brands like Anker, Belkin, and Mophie are known for their reliable power banks, and now Energizer is also entering the market. The convenience of wireless charging, such as Qi technology, is becoming more common in these batteries, offering a great feature for those who might forget their USB-C cables.

When selecting a power bank, consider its capacity to ensure it meets your device's needs. A 20,000mAh battery pack can typically charge an iPhone twice and a tablet once. For laptops, especially gaming models, you'll need a power bank with at least 45W of output. Having tested numerous power banks, I can guide you in choosing the perfect portable charger for your next trip.

1. 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 remember to pack them. 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 devicesOpt for a power bank with built-in cables to simplify your travels. The Belkin Boost Charge Plus 10K comes with integrated five-inch Lightning and USB-C cables, making charging easier and more convenient. Belkin ensures the cables are neatly stored in slots on either side of the charger, maintaining a compact size similar to a smartphone and weighing just half a pound.

This power bank is limited to charging via the two built-in cables, so you might need an adapter for less common devices. However, it supports most electronics, including the latest iPhones, through USB-C charging. The 10,000mAh capacity can power up smartphones and some tablets effectively, with a maximum output of 18W for single-device charging. It can charge two devices simultaneously, though this reduces the total output to 23W. Pass-through charging is also supported, allowing you to recharge the power bank while charging another device.

2. Anker 737 Laptop Charger

Best Power Bank for Charging Laptops

### Anker 737

2This powerful charger keeps your laptop running 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 chargingIncludes an informational displayCONSIt's bulkyLaptops demand more power than phones or tablets, and the Anker 737 meets this need with a total output of 140W, sufficient for most laptops and some gaming models. Its 24,000mAh capacity can fully charge most laptops once or twice.

The main drawback is its size, measuring 6.13 inches tall and 1.95 inches thick, which is larger than many laptops it charges. Weighing 1.39lbs, it adds significant weight to your bag. Despite its bulk, it's invaluable for on-the-go work, especially during events like CES where power outlets are scarce.

3. Charmast Portable Charger

Best Budget Power Bank

It supports 20W fast charging, though this is less than many premium models. Its design resembles the Belkin Boost Charge Plus 10K but is thicker and heavier at about 1 inch thick and 0.8lbs.

The Anker MagGo uses Qi2 technology for 15W wireless charging, nearing the speed of 20W fast charging. Its slim profile and light weight of 0.44lbs make it easy to carry, though its 10,000mAh capacity limits it to one or two full iPhone charges.

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 battery in most flagship phones means you'll need at least that much capacity to double your phone's life. Most power banks offer 10,000mAh or more, providing multiple charges on the go, though some power is lost during transfer.

Ports and charging speeds

Chargers vary in their output capabilities, with some supporting standards like Power Delivery (PD) for faster charging. For quick phone charging, aim for at least 20W, ideally 30W. Tablets require at least 30W, while laptops need 45W or more to charge effectively. Consider the charger's input speed too; a 20,000mAh battery with only 5W input will take longer 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 in power banks. In fact, doing so could damage them, reducing capacity. Charge your power bank before it's completely depleted or every few months when 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, but only 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 fine.

How long do power banks last?

Power bank longevity depends on usage, build quality, and capacity. Brands like Anker and Belkin typically last 2 to 4 years, while cheaper models vary. Higher capacity batteries tend to last longer. To extend life, avoid overcharging, store in a cool, dry place, and charge fully every three months.
