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, choosing a substandard one can lead to serious issues like overheating or swelling. It's crucial to opt for reputable brands like Anker, Belkin, and Mophie, which are known for their reliable power banks. Energizer is also making strides in this market. The convenience of power banks supporting Qi wireless charging is a notable advancement, offering a seamless charging experience even if you forget your USB-C cable.

When selecting a power bank, capacity is key. A 20,000mAh battery pack can typically provide about 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. Having tested numerous power banks, I'm well-equipped to guide you in choosing the perfect portable charger for your next trip.

Forget the hassle of packing cables with the Belkin Boost Charge Plus 10K, which features built-in five-inch Lightning and USB-C cables. These cables neatly tuck away into slots on either side of the charger, ensuring organized storage. Despite the added cables, the power bank 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 many modern devices support USB-C charging. With a 10,000mAh capacity, it's sufficient for charging smartphones and some tablets. The maximum output of 18W per cable is suitable for quick charging iPhones, reaching 50% in under 30 minutes. It supports simultaneous charging of two devices at a total output of 23W and includes pass-through charging for recharging the power bank while using it.

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 displayCONSIts size can be cumbersome

Laptops demand more power than phones or tablets, and the Anker 737 meets this need with a 140W output, suitable for most laptops and some gaming models. Its 24,000mAh capacity can fully charge a laptop once or twice. However, its size is a notable drawback; it's thicker than many laptops and weighs 1.39lbs, which can add significant weight to your bag.

Despite its bulk, the Anker 737 is invaluable for on-the-go work, especially during events like CES where power outlets are scarce. Its high capacity and fast charging capabilities make it a reliable choice for professionals who can't afford to run out of battery mid-project.

Quality power banks can be pricey, often around $80, but the Charmast Portable Charger offers a 20,000mAh capacity at half the price. While it's limited to 20W output, it still supports fast charging. Its design resembles the Belkin Boost Charge Plus 10K but is thicker and heavier, weighing 0.8lbs.

Wireless charging power banks are less common, and many use the slower first-generation Qi standard. The Anker MagGo, however, supports Qi2, offering 15W output, close to the 20W fast charging standard. Its compact size and light weight make it highly portable, 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 the most critical factor when choosing a power bank. Measured in milliamp-hours (mAh), a higher capacity means more charges for your devices. A 10,000mAh power bank is standard and can provide multiple charges for most smartphones. 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 capabilities. Standards like Power Delivery (PD) can maximize energy transfer. For quick phone charging, aim for at least 20W, ideally 30W. For iPads, 30W is a minimum, while laptops require 45W or more. Consider the charger's input speed as well; 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 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 they must be in your carry-on luggage due to fire risk. The TSA limits them to 100Wh or about 27,000mAh, so a standard 10,000mAh charger is typically fine.

How long do power banks last?

Power bank longevity depends on usage, build quality, and capacity. High-quality brands like Anker and Belkin typically last 2 to 4 years. To extend their lifespan, avoid overcharging, store them in a cool, dry place, and charge them fully every three months.
