As a frequent traveler across the country with a bag brimming with tech, I've faced the challenge of devices running out of power far from an outlet. Thankfully, modern power banks are so advanced and portable that this issue is largely a thing of the past. I just ensure my power bank is fully charged before I hit the road, and I rarely find myself stranded with a dead phone.

A quick search on Amazon reveals a vast array of power banks from brands you might not recognize. While these devices are essentially giant batteries and relatively simple, opting for a substandard product can lead to issues like overheating or swelling. It's crucial to choose wisely to avoid such hazards.
Trusted brands like Anker, Belkin, and Mophie have established themselves as leaders in the power bank market, with Energizer also making notable strides. The proliferation of power banks has led to innovations such as Qi wireless charging, adding convenience especially when you forget your USB-C cable.
When selecting a power bank, capacity is key. A 20,000mAh battery pack can typically provide about two full charges for an iPhone and one for a tablet. For laptops, especially gaming ones, a power bank with at least 45W output is essential due to their higher power consumption.
While I haven't tested every power bank listed here, my extensive experience with various models equips me to guide you in choosing the perfect portable charger for your next trip.

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 remember to pack them. 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 devicesForget the hassle of packing cables with the Belkin Boost Charge Plus 10K, which includes five-inch integrated Lightning and USB-C cables. These cables tuck neatly into slots on either side of the charger, ensuring a clutter-free and organized storage solution. Despite the added cables, the power bank remains compact, roughly the size of a smartphone and weighing just half a pound.
This power bank is limited to the two built-in cables for charging, so you may need an adapter for more unique devices. However, most modern electronics, including the latest iPhones, support USB-C charging, making this a minor concern for most users.
The 10,000mAh capacity is sufficient to charge smartphones and some tablets multiple times. With a maximum output of 18W when charging a single device via either the Lightning or USB-C cable, it's not ideal for laptops or other high-power devices. Nevertheless, an iPhone can reach 50% charge in under 30 minutes. It supports simultaneous charging of two devices at a total output of 23W, and pass-through charging allows recharging the power bank via the USB-C port while charging another device.
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 chargingIncludes informational displayCONSSignificantly largeLaptops, inherently more powerful than phones or tablets, require robust charging solutions like the Anker 737. This power bank offers a total output of 140W, sufficient for most laptops and even some lower-end gaming models. With 24,000mAh of power, it can fully charge most laptops once or twice.
The primary drawback is its size; at 6.13 inches tall and 1.95 inches thick, it's larger than many of the laptops it charges. Weighing 1.39lbs, it can add considerable weight to an already heavy bag.
Despite its bulk, the Anker 737 is invaluable for on-the-go professionals, particularly during events like CES where access to power outlets is scarce.
Charmast Portable Charger
Best Budget Power Bank
### Charmast Portable Charger
4This charger offers most features of premium models like the Mophie Powerstation Plus at half the cost, though it is bulkier and slower. 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 for remaining powerCONSMore bulky than premium optionsThe market for reliable power banks often comes with a high price tag, typically around $80. However, opting for a more affordable model like the Charmast Portable Charger can save you money. With a 20,000mAh capacity, it can charge your phone multiple times, but its output is limited to 20W, which is slower than many premium chargers.
Resembling the Belkin Boost Charge Plus 10K, the Charmast charger is thicker at about 1 inch and weighs more at 0.8lbs. While it's bulkier and slower, the lower price point is a compelling trade-off, especially if you're okay with a slightly longer charging time.
Anker MagGo Power Bank
Best Power Bank with Wireless Charging
### Anker MagGo
2While the Anker MagGo's battery capacity isn't the largest, its support for fast wireless charging on the go is a significant advantage. See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output15W (Qi2), 30W (USB-C)Ports1 x USB-CSize4.09" x 2.78" x 0.58"Weight0.44lbPROSCompact and lightweightSupports Qi2 wireless charging at 15WCONSLimited to 10,000mAh capacityWireless charging is a convenient feature, but few power banks do it well. Most use the first-generation Qi standard, limited to 7.5W. The Anker MagGo, however, supports Qi2, offering 15W output, nearly as fast as the typical 20W wired fast charging.
Weighing just 0.44lbs and only 0.58 inches thick, the MagGo is highly portable. However, its 10,000mAh capacity means it can only provide one or two full charges for an iPhone. Despite this, both wireless and USB-C charging are relatively quick.
Veektomx Mini Power Bank
Best Compact Power Bank
### Veektomx Mini Power Bank

At the size of a deck of cards but thinner and weighing only 5.8oz, it's perfect for pockets. Despite its small size, it packs a 10,000mAh battery, capable of fully charging most smartphones and more.
The Veektomx Mini Power Bank provides versatility with three ports: USB-A, USB-C, and microUSB, all supporting fast charging at 18W to 22.5W for a single device, along with pass-through charging.
Its durable plastic body with ribbing enhances grip and prevents drops. An LED battery level indicator adds convenience, and all this is available for around $25, making it an excellent value.

Versatile enough to charge other devices, including the upcoming Nintendo Switch 2, this power bank also features additional USB-C and USB-A ports. For a different approach, consider specialized Switch battery cases.
What to Look for in a Power Bank
Capacity
Capacity is the key specification to consider in a portable charger, measured in milliamp-hours (mAh). Most flagship phones have around 3,000mAh batteries, so a power bank with at least this capacity can double your phone's life. A 10,000mAh or higher capacity is common and can provide multiple charges on the go, though some power is lost in transfer.
Ports and charging speeds
Chargers vary in their charging capabilities, with some supporting higher voltages and amperages through standards like Power Delivery (PD). Match the charger's output with your device's supported charging speeds, and check which ports offer those speeds. For fast phone charging, aim for at least 20W, preferably 30W. For iPads, 30W is a minimum, while laptops may require 45W or 60W. Consider the charger's input speed as well; a 20,000mAh battery with only 5W 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. In fact, doing so can damage them and reduce their 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 as long as they use lithium-ion or lithium metal batteries. They must be in carry-on luggage due to fire risk, with size limits typically at 100Wh or around 27,000mAh, making a standard 10,000mAh charger safe to travel with.
How long do power banks last?
Power banks' longevity depends on usage, build quality, and capacity. High-quality brands like Anker and Belkin typically last 2 to 4 years, while less reputable brands 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.
