The market is flooded with power banks from countless brands, some of which you may not recognize. While these devices are essentially large batteries and seem simple, choosing a substandard one can lead to serious issues like overheating or swelling. It's crucial to opt for reputable brands like Anker, Belkin, Mophie, and now even Energizer, which have proven track records in producing safe and effective power banks. Many of these now support Qi wireless charging, adding convenience, especially if you forget a USB-C cable.
When selecting a power bank, capacity is key. A 20,000mAh battery can provide about two full charges for an iPhone and one for a tablet, while higher output models can even power laptops, especially if they support at least 45W for standard laptops or more for gaming ones. Having tested numerous power banks, I'm here to guide you in choosing the perfect portable charger for your next trip.

However, its size can be a drawback. At 6.13 inches tall and 1.95 inches thick, it's larger than many laptops, and at 1.39lbs, it adds significant weight to your bag. Despite its bulk, it's invaluable for events like CES, where power outlets are scarce, and you need continuous power for work.

What to Look for in a Power Bank
Capacity
Capacity is the most crucial aspect of a power bank, measured in milliamp-hours (mAh). For a significant boost, choose a power bank with at least 3,000mAh, matching the typical capacity of flagship phones. Most power banks today have at least 10,000mAh, offering multiple charges on the go. Keep in mind that some energy is lost during transfer, so you won't get the full capacity stated.
Ports and charging speeds
Charging capabilities vary, with some power banks supporting standards like Power Delivery (PD) for faster charging. For quick phone charging, aim for at least 20W, with 30W being ideal for larger phone batteries. Tablets require at least 30W, while laptops need 45W or more. Consider the power bank's input speed as well, as a slow-charging battery can be inconvenient.
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 not in use.
Can you bring portable power banks on a plane?
Yes, you can bring power banks on a plane, but only in carry-on luggage. The TSA limits them to 100Wh or about 27,000mAh, so a standard 10,000mAh power bank is typically fine.
How long do power banks last?
Power bank longevity varies based on usage, build quality, and capacity. Reputable brands like Anker and Belkin typically last 2 to 4 years. Higher-capacity batteries often last longer. To extend their life, avoid overcharging, store in a cool, dry place, and charge fully every three months.
