As a frequent traveler across the country, I often find my bag packed to the brim with technology. One of the biggest challenges I face is keeping all my devices charged, especially when I'm far from an outlet. Thankfully, modern power banks have become so efficient and portable that this issue is largely a thing of the past. All I need to do is remember to charge my power bank before I leave home, and I'm set to avoid the inconvenience of a dead phone on the go.

A quick search on Amazon reveals hundreds of power banks from brands you might not be familiar with. While these devices are essentially large batteries and not overly complex, selecting an unreliable one can lead to serious issues like battery swelling and overheating.
Fortunately, brands like Anker, Belkin, and Mophie have established themselves as leaders in reliable power bank manufacturing. Even Energizer is now entering the market. With the rise in Qi wireless charging, many power banks now support this feature, adding convenience especially when you forget your USB-C cable at home.
When choosing a power bank, the most crucial factor is ensuring it has enough capacity to keep your devices running. A 20,000mAh battery pack typically provides about two full charges for an iPhone and can charge a tablet once. For laptops, a power bank with at least 45W output is recommended, with gaming laptops needing even more.
Through my extensive experience with various power banks, I've honed in on what makes a good one. Here's a detailed look at some of the best options available to help you pick the perfect portable charger for your next trip.

Our Top Pick### Belkin Boost Charge Plus 10K
1This 10,000mAh power bank comes with built-in cables, eliminating the need to carry extras. See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output23WPorts1 x USB-C, 1 x LightningSize6.1" x 2.9" x 0.7"Weight0.5lbPROSHas a USB-C and Lightning cable built inCharges multiple devices CONSDoesn't have additional ports for other devicesForget the hassle of packing cables with the Belkin Boost Charge Plus 10K, which features integrated five-inch Lightning and USB-C cables for seamless charging. Belkin cleverly designed the cables to tuck away into slots on the sides, keeping them organized and out of the way. Despite the cables, the power bank remains compact, similar in size to a smartphone and weighing just half a pound.
While limited to these two cables, this power bank is versatile enough for most devices, especially those supporting USB-C. Its 10,000mAh capacity is sufficient for smartphones and some tablets, providing up to 50% charge for an iPhone in under 30 minutes. It supports simultaneous charging of two devices at a total output of 23W and includes pass-through charging for added convenience.
### Anker 737
2This robust charger is perfect for keeping your laptop powered all day. See it at AmazonProduct SpecificationsCapacity24,000mAhTotal output140WPorts1 x USB-C, 1 x USB-ASize6.13" x 2.15" x 1.95"Weight1.39lbPROSTons of wattage for fast chargingInformational display CONSIt's BIGLaptops demand more power than smartphones or tablets, necessitating a heavy-duty charging solution like the Anker 737. With a 140W output and a 24,000mAh capacity, this power bank can fully charge most laptops one to two times, and even handle some lower-end gaming laptops.
The downside is its size; at 6.13 inches tall and 1.95 inches thick, it's larger than most laptops it charges. It weighs 1.39lbs, adding significant weight to your travel bag. Despite its bulk, it's invaluable for on-the-go professionals, especially during events like CES where power outlets are scarce.
### Charmast Portable Charger
4This budget-friendly charger offers many features of premium models at half the cost, though it's bulkier and charges 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 showing remaining powerCONSA little bulkyHigh-quality power banks often come with a steep price tag, but the Charmast Portable Charger offers a cost-effective alternative. With a 20,000mAh capacity and 20W output, it provides fast charging for multiple devices, though at a slower pace than premium models.
Resembling the Belkin Boost Charge Plus 10K in design, it's slightly thicker at about 1 inch and weighs 0.8lbs. While it offers more power for less money, it's bulkier and takes longer to charge your devices, typically about an hour and a half instead of one hour.
### Anker MagGo
2The Anker MagGo may not boast the largest capacity, but its wireless charging capabilities make it a standout choice. See it at AmazonProduct SpecificationsCapacity10,000mAhTotal output15W (Qi2), 30W (USB-C)Ports1 x USB-CSize4.09" x 2.78" x 0.58"Weight0.44lbPROSExtremely portable and lightweightQi2 wireless charging at 15WCONSOnly 10,000mAhWhile many power banks require a wired connection, the Anker MagGo supports Qi2 wireless charging at 15W, nearly matching the speed of 20W fast charging. Its compact size and lightweight design, at just 0.44lbs and 0.58 inches thick, make it an ideal travel companion.
However, its 10,000mAh capacity limits you to one or two full charges for an iPhone. Despite this, its fast charging capabilities, whether wireless or via USB-C, make it a valuable asset for on-the-go charging.
### Veektomx Mini Power Bank

It features three charging ports (USB-A, USB-C, and microUSB) with fast charging outputs of 18W to 22.5W, and supports pass-through charging. Its durable plastic body and LED battery level indicator enhance its practicality, all at a budget-friendly price of around $25.

A built-in USB-C cable simplifies charging on the go, and additional ports allow for multi-device charging, though at slightly reduced speeds. Despite its bulkier design, it's manageable and can be paired with Jsaux's ModCase for a seamless integration with the Steam Deck.
### Emperor of Gadgets Portable Power Bank

It supports charging at 15W, suitable for the Switch's 18W maximum, and includes an integrated USB-C cable for easy connection.
This power bank is versatile enough to charge other devices as well, making it a practical choice for Switch owners looking to extend their gaming sessions without adding too much bulk.
Capacity is the most crucial aspect of a power bank, measured in milliamp-hours (mAh). A 3,000mAh battery in most flagship phones means you'll want a power bank with at least that capacity to double your phone's battery life. Most power banks today offer 10,000mAh or more, providing multiple charges on the go. Keep in mind, however, that some energy is lost during transfer, so you won't get the full stated capacity.
Not all chargers are the same; some offer higher charging speeds through increased voltage and amperage. Standards like Power Delivery (PD) can maximize energy transfer. For quick phone charging, aim for at least 20W, preferably 30W to keep up with larger phone batteries. For iPads, a minimum of 30W is recommended, while laptops require 45W or 60W to stay powered. Also, consider the power bank's input speed; a 20,000mAh battery with only 5W input will take longer to recharge.
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. It's best to charge your power bank before it's completely depleted or every few months if it's not in use.
Yes, you can bring power banks on a plane if they use lithium-ion or lithium metal batteries. According to TSA regulations, they must be in your carry-on luggage, not checked bags, due to fire risk. The size limit is typically 100Wh or about 27,000mAh, making standard 10,000mAh chargers safe to travel with.
The lifespan of a power bank depends on usage, build quality, and capacity. High-quality brands like Anker and Belkin typically last 2 to 4 years. Cheaper models may vary in longevity. Higher capacity batteries tend to last longer. To extend the life of your power bank, avoid overcharging, store it in a cool, dry place, and charge it fully every three months.
