With the vast array of power banks available on Amazon, from brands you might not recognize, it's crucial to choose wisely. While power banks are essentially large batteries, opting for a substandard one can lead to serious issues like overheating or swelling. Trusted brands like Anker, Belkin, and Mophie have established themselves as reliable choices, with Energizer also making notable strides. Many of these power banks now support Qi wireless charging, adding convenience, especially if you forget a USB-C cable.

The key is selecting a power bank with sufficient capacity to keep your devices running. A 20,000mAh battery pack can typically provide about two full charges for an iPhone and one for a tablet. For laptops, a power bank with at least 45W output is necessary, with gaming laptops needing even more. My experience with numerous power banks has honed my ability to identify the best options for various needs.

Best Power Bank

Our Top Pick### Belkin Boost Charge Plus 10K

This 10,000mAh power bank comes with built-in cables, eliminating the worry of forgetting them. With integrated Lightning and USB-C cables, it's designed for convenience. The cables tuck neatly into slots on either side of the charger for organized storage, maintaining a compact size similar to a smartphone and weighing just half a pound. While it only supports charging via the two built-in cables, this is sufficient for most users, especially those with devices compatible with USB-C. The 10,000mAh capacity is ideal for charging smartphones and some tablets, though its 18W output per cable is better suited for phones. It supports simultaneous charging of two devices at a total output of 23W and includes pass-through charging for added versatility.

Laptops demand more power than phones or tablets, and the Anker 737 is designed to meet this need. With a 140W total output and a 24,000mAh capacity, it can charge most laptops once or twice. Its size, however, is a consideration—standing at 6.13 inches tall and 1.95 inches thick, it's larger than many laptops. Weighing 1.39lbs, it adds significant weight to your bag. Despite its bulk, the Anker 737 is invaluable for working on the go, ensuring you never run out of battery during critical moments, such as at events like CES where power outlets are scarce.

3. Charmast Portable Charger

High-quality power banks can be pricey, but the Charmast Portable Charger offers a cost-effective alternative. With a 20,000mAh capacity and a 20W output, it can charge your phone multiple times, though at a slower rate than premium models. It's slightly bulkier and heavier than top-tier options but provides excellent value. The design is reminiscent of the Belkin Boost Charge Plus 10K, but at half the price, it's a compelling choice for those looking to save without sacrificing too much on performance.

4. Anker MagGo Power Bank

Best Power Bank with Wireless Charging

### Anker MagGo

Wireless charging power banks are less common, and the Anker MagGo stands out with its support for Qi2, offering a 15W output for faster charging. Its compact size and lightweight design make it highly portable, though its 10,000mAh capacity limits it to one or two full charges for an iPhone. The MagGo's versatility and speed, whether charging wirelessly or via USB-C, make it an excellent choice for those who value convenience and efficiency.

5. Veektomx Mini Power Bank

The Veektomx Mini Power Bank is the epitome of portability, fitting easily into a pocket with its deck-of-cards size and weighing just 5.8oz. Despite its small size, it boasts a 10,000mAh capacity, capable of fully charging most smartphones. It features three charging ports—USB-A, USB-C, and microUSB—supporting fast charging up to 22.5W. Its durable design and LED battery indicator add to its appeal, making it a great value at around $25.

The Steam Deck's battery life can be a challenge, but the Jsaux Power Bank 20,000mAh 65W offers a solution. With a 20,000mAh capacity and a 65W output, it can charge the Steam Deck quickly, reaching full charge in about three hours. It includes a built-in USB-C cable and additional ports for other devices, though its bulkier design is a trade-off for its powerful performance. The Jsaux ModCase for the Steam Deck further enhances its usability, allowing the power bank to attach directly to the device.

What to Look for in a Power Bank

Capacity

Capacity is the most crucial 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 typically provide three or more charges for most smartphones. Keep in mind that some power is lost during transfer, so the actual capacity might be slightly less.

Ports and charging speeds

Different power banks offer varying charging capabilities. Look for standards like Power Delivery (PD) for faster charging. For smartphones, a minimum of 20W output is recommended, with 30W being ideal for larger batteries. For iPads, aim for at least 30W, and for laptops, 45W to 60W is necessary. Also, consider the power bank's input speed, as a higher input can reduce recharge time.

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 concerns. The TSA limits them to 100Wh or about 27,000mAh, so a standard 10,000mAh power bank is usually fine.

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.
