While a quick search on Amazon will reveal hundreds of power banks from lesser-known brands, it's crucial to choose a reliable one. Issues like battery swelling and overheating can occur with substandard units, which is something to avoid at all costs. Leading brands like Anker, Belkin, and Mophie have established themselves as trustworthy sources for power banks, with Energizer now joining the fray. The convenience of wireless charging is becoming more common in these devices, adding an extra layer of flexibility, especially if you forget to pack a USB-C cable.
When selecting a power bank, the most critical factor is its capacity. A 20,000mAh battery pack can typically provide about two full charges for an iPhone and one for a tablet. For laptop charging, a power bank with at least 45W output is essential, with gaming laptops requiring even higher output. Having used numerous power banks over the years, I'm well-versed in what to look for and am here to guide you in choosing the best one for your travels.

The Belkin Boost Charge Plus 10K features five-inch integrated Lightning and USB-C cables, making life easier. Worried about tangled wires? Belkin has a solution with each cable neatly tucking into a slot on either side of the charger for organized storage. Despite the cables, this power bank remains compact, similar in size to a smartphone and weighing only half a pound.
While limited to these two cables, the power bank is versatile enough for most devices, especially those supporting USB-C charging. Its 10,000mAh capacity provides ample power for smartphones and some tablets. With a maximum output of 18W for single-device charging, it's not suitable for laptops, but can get an iPhone to 50% in under 30 minutes.

The downside is its size; at 6.13 inches tall and 1.95 inches thick, it's larger than many laptops. Weighing 1.39lbs, it adds considerable weight to your bag. However, its utility is undeniable when working remotely, particularly at events like CES, where power outlets are scarce.

What to Look for in a Power Bank
Capacity
Capacity is the most crucial spec in a portable charger, measured in milliamp-hours (mAh). For smartphones with 3,000mAh batteries, a 10,000mAh charger can provide three or more charges. Keep in mind some power loss during transfer, so the full capacity isn't always available.
Ports and charging speeds
Chargers vary in their capabilities, with some supporting higher voltages and amperages, like Power Delivery (PD). Match the charger's output with your device's charging speed, and check which ports offer those speeds. For smartphones, 20W to 30W is ideal for quick charging. For iPads, 30W is a minimum, and laptops require 45W to 60W. Consider the charger's input speed as well, as a large capacity with slow 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 if they use lithium-ion or lithium metal batteries. They must be in carry-on luggage, not checked bags, due to fire risk. The TSA limits them to 100Wh or about 27,000mAh, so a standard 10,000mAh charger is well within limits.
How long do power banks last?
Power bank longevity depends on usage, quality, and capacity. Brands like Anker and Belkin typically last 2 to 4 years. Cheaper models may vary. Higher capacity batteries tend to last longer. To extend lifespan, avoid overcharging, store in a cool, dry place, and charge fully every three months.
