A quick search on Amazon reveals hundreds of power banks from lesser-known brands. While these devices are essentially just large batteries and relatively simple, choosing an unreliable one can lead to serious issues, such as overheating or swelling. To avoid such risks, it's wise to stick with reputable manufacturers like Anker, Belkin, and Mophie, with Energizer now joining the fray. Many of these power banks now support Qi wireless charging, adding convenience for those who might forget to pack a USB-C cable.

When selecting a power bank, capacity is crucial. A 20,000mAh battery can typically provide two full charges for an iPhone and charge a tablet once. For laptops, especially gaming ones, a power bank with at least 45W output is necessary due to their higher power demands.

Having used numerous power banks, I've gained insight into what makes a great portable charger. Here's a detailed look at some of the best options available, tailored to different needs and preferences.

This 10,000mAh power bank comes with built-in cables, eliminating the hassle of forgetting to pack them. The Belkin Boost Charge Plus 10K features integrated Lightning and USB-C cables, making it incredibly user-friendly. These cables neatly tuck away into slots on either side of the charger, ensuring a clutter-free and compact design that's about the size of a smartphone and weighs just half a pound.

While it's limited to these two cables, the majority of modern devices, including the latest iPhones, support USB-C charging, making it versatile for most users. The 10,000mAh capacity offers ample power for smartphones and some tablets, with a maximum output of 18W when charging one device, or 23W when charging two simultaneously. It also supports pass-through charging, allowing you to recharge the power bank while charging another device.

The Anker 737 is a powerhouse designed to keep laptops charged throughout the day. With a total output of 140W and a 24,000mAh capacity, it's capable of charging most laptops once or twice, and even some lower-end gaming laptops. The downside is its size; at 6.13 inches tall and 1.95 inches thick, it's larger than many laptops it's designed to charge, and weighs 1.39lbs, which can be a burden in a packed bag.

Despite its bulk, the Anker 737 is invaluable for those working on the go, particularly during events like CES where power outlets are scarce. Its high wattage ensures fast charging, and an informational display keeps you updated on its status.

3. Charmast Portable Charger

The Charmast Portable Charger offers a budget-friendly alternative to premium options, delivering 20,000mAh of power at a 20W output. While it's bulkier and charges slower than high-end models, it provides excellent value, costing around half the price of similar high-capacity chargers. Its design resembles the Belkin Boost Charge Plus 10K but is thicker and heavier at 0.8lbs.

Despite its slower charging speed, the Charmast charger still offers fast charging capabilities and includes a digital display to show remaining power, making it a practical choice for those watching their budget.

The Anker MagGo stands out for its wireless charging capabilities. With a 10,000mAh capacity, it might not be the largest, but it supports Qi2 wireless charging at 15W, nearing the speed of wired fast charging. Its compact size and lightweight design, at just 0.44lbs and 0.58 inches thick, make it an ideal travel companion.

While its capacity limits it to one or two full iPhone charges, the Anker MagGo's fast charging, both wirelessly and via USB-C, compensates for this limitation, offering a convenient and efficient solution for on-the-go charging.

This power bank is not only perfect for the current Switch but also compatible with the upcoming Nintendo Switch 2, making it a future-proof option for gamers.

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), it determines how many times you can charge your device. A 10,000mAh capacity is standard and can provide multiple charges for most smartphones. However, there's always some energy loss during transfer, so you won't get the full mAh rating.

Ports and charging speeds

Not all chargers are equal in terms of ports and charging speeds. Some support standards like Power Delivery (PD) for faster charging. For smartphones, at least 20W is recommended, with 30W being ideal for larger batteries. For iPads, 30W is the minimum, and laptops require 45W to 60W to keep up with their power needs. Also, consider the power bank's input speed to ensure quick recharging.

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. Instead, charge it 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. The TSA requires them to be in carry-on luggage only, with a size limit of 100Wh or about 27,000mAh, making standard 10,000mAh chargers perfectly acceptable.

How long do power banks last?

The lifespan of a power bank varies based on usage, build quality, and capacity. High-quality 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.
