0See it at AmazonIn today's market, a quick search on Amazon reveals hundreds of power banks from lesser-known brands. While these devices are essentially large batteries and not overly complex, selecting a substandard one can lead to serious issues like overheating or swelling. It's crucial to choose wisely to avoid such hazards.
Trusted brands like Anker, Belkin, and Mophie have established themselves as leaders in producing reliable power banks. Even Energizer is making a mark in this space. What's exciting is the trend towards integrating Qi wireless charging into these devices, adding convenience for those who might forget a USB-C cable at home.
When selecting a power bank, capacity is key. A 20,000mAh battery can typically provide two full charges for an iPhone and a single charge for a tablet. For laptops, particularly gaming models, you'll need a power bank with at least 45W output to meet their higher power demands.
Having used numerous power banks over the years, I've developed a keen eye for what makes a portable charger stand out. I'm here to guide you in selecting the perfect one for your travels.

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 additional ones. See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output23WPorts1 x USB-C, 1 x LightningSize6.1" x 2.9" x 0.7"Weight0.5lbPROSFeatures a built-in USB-C and Lightning cableCapable of charging multiple devicesCONSNo additional ports for other devicesThe Belkin Boost Charge Plus 10K simplifies your life by including five-inch integrated Lightning and USB-C cables. These cables tuck neatly into slots on either side of the charger for tangle-free storage. Despite the built-in cables, the power bank remains compact, similar in size to a smartphone and weighing only half a pound.
Although this power bank is limited to the two built-in cables, it supports most modern devices, including the latest iPhones, making it versatile for the majority of users. With a 10,000mAh capacity, it's sufficient for recharging smartphones and some tablets. The maximum output of 18W per cable is ideal for quick charging iPhones, reaching 50% in less than 30 minutes. You can charge two devices at once, though the total output then drops to 23W. It also supports pass-through charging, allowing you to recharge the power bank and another device simultaneously.
Anker 737 Laptop Charger
Best Power Bank for Charging Laptops
### Anker 737
2This powerful charger ensures your laptop stays 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"Weight1.39lbPROSProvides ample wattage for rapid chargingFeatures an informational displayCONSIts size and weight may be cumbersomeLaptops require more robust charging solutions than phones or tablets, and the Anker 737 fits the bill. With a 140W output, it's capable of powering most laptops, including some gaming models. Coupled with a 24,000mAh capacity, it can fully charge a laptop one or two times.
The Anker 737's size is its main drawback. At 6.13 inches tall and 1.95 inches thick, it's bulkier than many laptops it's designed to charge. Weighing 1.39lbs, it adds significant weight to an already heavy bag. However, its utility is undeniable when working remotely, especially at events like CES where power outlets are scarce.
Charmast Portable Charger
Best Budget Power Bank
### Charmast Portable Charger
4This budget-friendly charger offers features similar to the Mophie Powerstation Plus at half the cost, albeit with increased bulk and slower charging. See it at AmazonProduct SpecificationsCapacity20,000mAhTotal output20WPorts1 x USB-C/Micro combo, 1 x Lightning, 1 x USB-A Size5.91" x 2.83" x 1.09"Weight368gPROSSupports 20W fast chargingIncludes a digital display for power statusCONSMore bulky than premium optionsHigh-quality power banks often come with a hefty price tag, but the Charmast Portable Charger provides a cost-effective solution. With a 20,000mAh capacity, it can recharge your phone multiple times, though its output is limited to 20W, suitable for fast charging but less than premium models.
Resembling the design of the Belkin Boost Charge Plus 10K, the Charmast charger is thicker at about 1 inch and weighs 0.8lbs. While it offers more power for less money, the trade-off is slower charging and added bulk. However, at half the price, it's a reasonable compromise, even if it means waiting an extra half hour for a full charge.
Anker MagGo Power Bank
Best Power Bank with Wireless Charging
### Anker MagGo
2While its battery capacity may be modest, the Anker MagGo excels in providing efficient wireless charging on the go. See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output15W (Qi2), 30W (USB-C)Ports1 x USB-CSize4.09" x 2.78" x 0.58"Weight0.44lbPROSCompact and lightweightSupports 15W Qi2 wireless chargingCONSLimited to 10,000mAh capacityWireless charging is a premium feature in power banks, and the Anker MagGo stands out with its Qi2 support, offering up to 15W output—close to the 20W fast charging standard. Its compact design, weighing just 0.44lbs and only 0.58 inches thick, makes it an ideal travel companion.
The downside is its 10,000mAh capacity, which limits it to one or two full charges of an iPhone. However, the Anker MagGo compensates with relatively quick charging, whether through its wireless feature or the USB-C port.

What to Look for in a Power Bank
Capacity
The capacity of a power bank, measured in mAh, is crucial for determining how many times it can charge your devices. For smartphones with 3,000mAh batteries, a power bank with at least that capacity can double your phone's battery life. Most power banks today offer 10,000mAh or more, capable of providing multiple charges on the go. Remember, some power is lost during transfer, so you won't get the full capacity stated.
Ports and charging speeds
Different power banks offer varying charging capabilities, with some supporting standards like Power Delivery (PD) for faster charging. For quick smartphone charging, aim for at least 20W, ideally 30W, to keep up with larger battery capacities. For iPads, 30W is a minimum, while laptops require 45W or more to outpace their power consumption. Consider the power bank's input wattage as well; a higher input means faster recharging of the power bank itself.
Power Bank FAQ
Should you drain your power bank before charging it again?
It's not necessary to fully drain lithium-based batteries found in power banks. In fact, doing so can damage the battery and reduce its capacity. Charge your power bank before it's completely depleted, or every few months if it's 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 or as a personal item due to the risk of fire. The TSA allows lithium ion or lithium metal batteries up to 100Wh or about 27,000mAh, so a standard 10,000mAh power bank is typically fine.
How long do power banks last?
The lifespan of a power bank varies based on usage, build quality, and capacity. Reputable brands like Anker and Belkin typically last 2 to 4 years. To extend the life of your power bank, avoid overcharging, store it in a cool, dry place, and charge it fully every three months.
