As a frequent traveler, I understand the frustration of having tech gadgets run out of power far from an outlet. Thankfully, modern power banks have become compact and efficient enough to resolve this issue. With a reliable power bank, I ensure it's fully charged before I leave home, which usually prevents me from being stuck with a dead device on my journeys.

With the vast array of power banks available, particularly on platforms like Amazon, it's easy to be overwhelmed by the options, many of which are from lesser-known brands. While power banks are essentially large batteries and might seem straightforward, choosing a low-quality one can lead to issues such as overheating or swelling. It's crucial to select from reputable brands like Anker, Belkin, Mophie, and now even Energizer, which have established themselves as leaders in the industry. The market has also evolved to include power banks with Qi wireless charging capabilities, adding convenience for users who might forget to pack a USB-C cable.
When selecting a power bank, capacity is key. A 20,000mAh battery pack can typically provide around two full charges for an iPhone and one for a tablet. For laptop users, a power bank with at least 45W of output is essential, with gaming laptops requiring even more power. From my extensive experience with various power banks, I'm here to guide you in finding the perfect portable charger for your needs.

What to Look for in a Power Bank
Capacity
When choosing a power bank, capacity is crucial. This is measured in milliamp-hours (mAh), and a higher capacity means more charges for your devices. Most flagship phones have a 3,000mAh battery, so a power bank with at least this capacity can double your phone's battery life. Standard power banks typically offer 10,000mAh or more, providing multiple charges on the go. Keep in mind that some power is lost during transfer, so you won't get the full stated capacity.
Ports and charging speeds
Not all chargers are equal; some offer higher charging speeds with different standards like Power Delivery (PD). For quick phone charging, at least 20W output is recommended, with 30W being ideal for larger batteries. For iPads, 30W is a minimum, and for laptops, 45W or 60W is necessary to outpace power consumption. Consider the charger's input speed as well; a high-capacity battery 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 in power banks. In fact, allowing them to completely drain can damage the battery and reduce its capacity. Charge your power bank before it's fully 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 around 27,000mAh, so standard 10,000mAh power banks are generally fine.
How long do power banks last?
Power bank longevity depends on usage, build quality, and capacity. Reputable brands like Anker and Belkin typically last 2 to 4 years. To extend their life, avoid overcharging, store them in a cool, dry place, and charge them fully every three months.
