As someone who travels frequently across the country with a bag packed full of gadgets, I've learned that running out of power can be a major inconvenience. Thankfully, modern power banks are so efficient and portable that they've largely solved this issue for me. I just ensure my power bank is fully charged before I leave, and I'm usually covered for my entire trip.

0See it at AmazonWith hundreds of power banks available on Amazon from lesser-known brands, it's crucial to choose wisely. These devices are essentially large batteries, and while they're not overly complex, a low-quality power bank can be hazardous, potentially swelling or overheating. Trusted brands like Anker, Belkin, and Mophie have established themselves as reliable manufacturers, and now even Energizer is making a mark in this space. The trend of integrating Qi wireless charging into power banks is a game-changer, offering convenience especially if you forget your USB-C cable at home.
Above all, you'll want a power bank with sufficient capacity to keep your devices powered. A 20,000mAh battery can typically charge an iPhone twice and a tablet once. For laptops, a power bank with at least 45W of output is essential, with gaming laptops needing even more. Although I haven't tested every power bank listed here, my extensive experience has equipped me to guide you in selecting the perfect portable charger for your next adventure.

Belkin Boost Charge Plus 10K
Best Power Bank
Our Top Pick### Belkin Boost Charge Plus 10K
1This 10,000mAh power bank comes with built-in cables, eliminating the need to carry extra ones. See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output23WPorts1 x USB-C, 1 x LightningSize6.1" x 2.9" x 0.7"Weight0.5lbPROSIntegrated USB-C and Lightning cablesCharges multiple devicesCONSLimited to built-in cables onlyChoose a power bank like the Belkin Boost Charge Plus 10K to avoid the hassle of remembering cables. It features integrated five-inch Lightning and USB-C cables, designed to tuck away neatly into the charger's sides, keeping everything organized and tangle-free. Despite its added cables, it remains compact, roughly the size of a smartphone and weighing only half a pound.
While the Belkin power bank only supports charging through its two built-in cables, this is generally sufficient for most users, as many modern devices, including the latest iPhones, support USB-C charging. With a 10,000mAh capacity, it provides ample power for smartphones and some tablets. Its maximum output is 18W for single-device charging on either cable, suitable for quickly boosting an iPhone to 50% in under 30 minutes. It can charge two devices simultaneously at a combined 23W and supports pass-through charging via its USB-C port.
Anker 737 Laptop Charger
Best Power Bank for Charging Laptops
### Anker 737
2This powerhouse keeps your laptop charged 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 chargingInformative displayCONSConsiderable sizeLaptops demand more power than phones or tablets, and the Anker 737 is built to meet that need with a 140W output, sufficient for most laptops and some entry-level gaming models. Its 24,000mAh capacity can fully charge a laptop once or twice.
The Anker 737's bulkiness, measuring 6.13 inches tall and 1.95 inches thick, is its main drawback. It weighs 1.39lbs, which can add up when you're already carrying a laptop and other items. However, its size is justified when you're working remotely and need reliable power, especially at events like CES where outlets are scarce.
Charmast Portable Charger
Best Budget Power Bank
### Charmast Portable Charger
4This charger offers many features similar to the Mophie Powerstation Plus at half the cost, though it's larger and charges more slowly.

While its output is limited to 20W, it's still capable of fast charging.
The Charmast resembles the Belkin Boost Charge Plus 10K in design but is thicker at about 1 inch and weighs 0.8lbs. You're trading off some speed and size for cost savings, with your phone taking an hour and a half to charge instead of one hour.

The Anker MagGo, however, supports Qi2, offering 15W for faster wireless charging.
Extremely portable at just 0.44lbs and 0.58 inches thick, the MagGo is easy to carry. Its 10,000mAh capacity might limit you to one or two full charges of an iPhone, but it compensates with fast charging via both wireless and USB-C methods.

What to Look for in a Power Bank
Capacity
Capacity is crucial when choosing a power bank. Measured in milliamp-hours (mAh), a 3,000mAh battery can double the life of most flagship phones. A 10,000mAh or higher capacity is standard, providing multiple charges on the go. Remember, some power is lost during transfer, so you might not get the full capacity.
Ports and charging speeds
Different chargers offer varying levels of power. Standards like Power Delivery (PD) can maximize charging speeds. For phones, aim for at least 20W, ideally 30W, for quick charging. iPads require at least 30W, while laptops need 45W or 60W to charge efficiently. Consider the charger's input speed too; a 20,000mAh battery with a slow 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 found in most power banks. Doing so can damage the battery and reduce its capacity. Charge your power bank before it's completely depleted and 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. The TSA allows them in carry-on luggage only, not in checked bags, due to fire risks. The size limit is typically around 100Wh or 27,000mAh, so a standard 10,000mAh power bank is usually fine.
How long do power banks last?
Power banks can last 2 to 4 years, depending on usage, build quality, and capacity. Brands like Anker and Belkin 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.
