A quick search on Amazon reveals a plethora of power banks from lesser-known brands. While these devices are essentially large batteries and relatively simple, selecting a substandard one can lead to serious issues, such as swelling or overheating. Reputable brands like Anker, Belkin, and Mophie are known for their reliable power banks, and even Energizer is entering the market. These brands often support Qi wireless charging, enhancing the convenience of charging on the go, especially if you forget a USB-C cable.

Choosing a power bank with sufficient capacity is crucial to keep your devices powered. A 20,000mAh battery pack can typically charge an iPhone twice and a tablet once. For laptops, especially gaming models, a power bank with at least 45W of output is essential. With extensive experience using various power banks, I'm here to guide you in selecting the ideal portable charger for your next journey.

1. Belkin Boost Charge Plus 10K

Best Power Bank

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

1This 10,000mAh power bank comes with built-in cables, eliminating the need to carry extra ones. See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output23WPorts1 x USB-C, 1 x LightningSize6.1" x 2.9" x 0.7"Weight0.5lbPROSIntegrated USB-C and Lightning cablesCan charge multiple devicesCONSNo additional ports for other devices

Forget the hassle of remembering cables by opting for a power bank with built-in cables. The Belkin Boost Charge Plus 10K includes five-inch integrated Lightning and USB-C cables, simplifying your life. Belkin ensures the cables remain tangle-free with a slot on each side of the charger for neat storage when not in use. Despite the cables, the power bank remains compact, similar in size to a smartphone and weighing just half a pound.

This power bank is limited to charging with its two cables, so you may need an adapter for less common devices. However, most modern electronics, including the latest iPhones, support USB-C charging, making this a non-issue for most users.

With a 10,000mAh capacity, this power pack provides ample power for smartphones and some tablets. It delivers up to 18W when charging one device via either the Lightning or USB-C cable, which is not ideal for laptops but can charge an iPhone to 50% in under 30 minutes. Two devices can be charged simultaneously, though the total output drops to 23W. Pass-through charging is supported, allowing you to recharge the power bank while charging another device.

2. Anker 737 Laptop Charger

Best Power Bank for Charging Laptops

### Anker 737

2This robust charger ensures your laptop stays powered throughout the day. See it at AmazonProduct SpecificationsCapacity24,000mAhTotal output140WPorts1 x USB-C, 1 x USB-ASize6.13" x 2.15" x 1.95"Weight1.39lbPROSHigh wattage for fast chargingInformational displayCONSSizeable and heavy

Laptops demand more power than phones or tablets, requiring robust charging solutions like the Anker 737. With a total output of 140W, this power bank is ideal for most laptops and some lower-end gaming models. It boasts a 24,000mAh capacity, sufficient to fully charge most laptops once or twice.

The downside is its size; the Anker 737 measures 6.13 inches tall and 1.95 inches thick, which is bulkier than many laptops. Weighing 1.39lbs, it adds significant weight to your bag, especially when combined with other items.

Despite its bulk, the Anker 737 is invaluable for working on the go, ensuring you don't run out of battery mid-project. It's particularly useful at events like CES, where I'm often writing without access to a power outlet.

3. Charmast Portable Charger

Best Budget Power Bank

### Charmast Portable Charger

4This portable charger offers many features of the Mophie Powerstation Plus at half the price, though it's bulkier and charges more slowly. See it at AmazonProduct SpecificationsCapacity20,000mAhTotal output20WPorts1 x USB-C/Micro combo, 1 x Lightning, 1 x USB-A Size5.91" x 2.83" x 1.09"Weight368gPROS20W fast chargingDigital display showing remaining powerCONSSlightly bulky

Reliable power banks can be expensive, often around $80, but the Charmast power bank offers a 20,000mAh capacity for half the price. While limited to 20W output, it still supports fast charging. Its design resembles the Belkin Boost Charge Plus 10K but is thicker and heavier at about 1 inch thick and 0.8lbs. Though it charges slower, it's a great value, even if it takes an hour and a half to charge a phone instead of one hour.

4. Anker MagGo Power Bank

Best Power Bank with Wireless Charging

### Anker MagGo

2The Anker MagGo may not have the highest battery capacity, but it excels in providing efficient wireless charging on the go.

While many power banks offer wired charging, few provide reliable wireless charging. Most use the first-generation Qi standard, limited to 7.5W, resulting in slow charging. The Anker MagGo, however, supports Qi2, delivering 15W, nearly matching the speed of 20W fast charging.

Weighing just 0.44lbs and only 0.58 inches thick, the MagGo is highly portable. Its 10,000mAh capacity may only provide one or two full charges for an iPhone, but it charges quickly, whether wirelessly or via the USB-C port.

While many power banks are portable, the Veektomx Mini Power Bank stands out for its compactness, resembling a deck of cards but thinner and weighing only 5.8oz. Despite its size, it provides a 10,000mAh battery, sufficient for a full smartphone charge and more.

With three ports (USB-A, USB-C, and microUSB), it offers versatility and supports fast charging up to 22.5W for a single device, with pass-through charging available. Its durable plastic body with ribbing prevents drops, and an LED indicator shows the remaining power. Priced around $25, it's a great value.

The Steam Deck's battery life can be challenging, even with the Steam Deck OLED's improvements. The Jsaux Power Bank 20,000mAh 65W is an excellent accessory, providing a 20,000mAh capacity for at least one full charge. With a 45W charging speed, it can fully charge the Steam Deck in about three hours.

A built-in USB-C cable simplifies charging on the go, and additional ports (one USB-C and two USB-A) allow for multi-device charging, though speeds may decrease. Despite its bulk, weighing around 1lb and being an inch thick, it's manageable and fits into bags. Jsaux also offers a ModCase for the Steam Deck with a strap to attach the power bank, making the integrated cable reach perfectly.

What to Look for in a Power Bank

Capacity

Capacity is the key spec to consider in a portable charger, measured in milliamp-hours (mAh). Most flagship phones have a 3,000mAh battery, so a charger with at least this capacity can double your phone's battery life. A 10,000mAh or higher capacity is standard and should provide three or more charges on the go, though some power is lost during transfer.

Ports and charging speeds

Not all chargers are equal in terms of charging capabilities. Some use standards like Power Delivery (PD) for maximum energy transfer. Compare the charger's output capabilities with your device's supported charging speeds, and check which ports offer these speeds. For quick phone charging, at least 20W is recommended, while 30W is ideal for larger phone batteries. For iPads, 30W is a minimum, and laptops require 45W to 60W to outpace their power consumption.

Consider the charger's input speed as well; a 20,000mAh battery with only 5W input will take a long time to recharge.

Power Bank FAQ

Should you drain your power bank before charging it again?

No, it's not necessary to drain lithium-based batteries, which are common in power banks. Fully draining them 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 planes, provided they use lithium-ion or lithium metal batteries. The TSA allows them only in carry-on luggage or as personal items, not in checked bags due to fire risk. The size limit is typically 100Wh or around 27,000mAh, making a standard 10,000mAh charger permissible.

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, while cheaper models may vary. Higher capacity batteries tend to last longer. To extend the lifespan, avoid overcharging, store in a cool, dry place, and fully charge every three months.
