We live in a world of power-hungry devices that require daily charging. But when we travel, keeping the multitude of smartphones, tablets, laptops, and gear charged is difficult. When we run out of juice on the road, we turn to portable power banks to keep things charged.
Not all power banks are the same. Like buying AA batteries for a remote, you need a good quality battery to give you a long-lasting charge. But how can you spot a good power bank on Amazon when the site is flooded with cheap knockoffs?
I’ll list the key factors to consider when buying a power bank, explain the FAA regulations about flying with them, and review the best power banks for travel.

What to Consider When Buying a Power Bank
Many numbers are involved when buying a power bank – capacity and max output being the top two. But what do all these numbers mean? And what else should you consider?
Here’s a complete breakdown of everything to consider when buying a power bank.
Capacity
The capacity of a power bank is measured in milliamp hours, expressed as mAh. Without getting technical, it’s the measurement of power the battery can hold.
To put this into perspective, the iPhone 15 Pro Max has a 4,441 mAh battery, the Samsung Galaxy S23 Ultra has a 3,900 mAh battery, and the iPad Pro 12.9” has a 10,758 mAh battery.
When choosing a power bank, consider how many charges you’ll get in your devices. A 20,000 mAh battery is a good standard.
Max Power Output
The measurement of flowing power is measured in watts. A power bank’s max power output tremendously impacts how it is used.
The maximum output of a power bank is the amount of power output by all USB ports combined. The maximum output of individual ports can vary depending on how many USB ports are used simultaneously. Better power banks have a greater power output when multiple ports are used.
The maximum output of any single USB port determines what can be charged. Most smartphones require at least 15W, and laptops require about 60W. Anything less is called a trickle charge – it takes significantly longer to charge, and you can’t use the device while charging.
Number of USB Ports
The number of USB ports determines how many devices can be charged simultaneously. Three USB ports are a good standard – it allows you to charge two smartphones and another device simultaneously.
The type of USB port is only a minor issue. Now that Apple has ditched the Lightning port in favor of USB-C, keeping all your devices charged is easier than ever. The USB-C port is the most common on power banks, but having at least one USB-A is still necessary.
Size and Weight
The size and weight of a power bank determines how easy it is to pack in your luggage and whether you can put it in your pocket.
Smaller power banks, wall chargers, and USB cables are easy to pack in tech bags. But larger power banks are difficult to pack inside tech bags, requiring them to be stuffed between packing cubes or inside a dedicated pocket in your luggage.
Weight is typically only a factor when you’re flying. FAA regulations require all lithium-ion batteries to be carried onto the plane. Heavier power banks mean you have less available weight for clothes and accessories.
FAA Regulations
The good news is that you can fly with most power banks. But before you head to the airport, check this list of FAA regulations and procedures:
- All lithium-ion batteries must be in the carry-on bag
- The batteries must be removed from the bag during inspection
- Lithium-ion batteries are limited to 100 Watt-Hours per battery
- Battery terminals must be protected
So, what does all this mean?
100 Watt-Hours includes almost all portable power banks, so there is nothing to worry about there.
But the thing to watch out for is “battery terminals must be protected.” This means your power banks must be stored in pouches, dedicated pockets in tech bags, or specialized carry cases for the power bank. Many power banks have additional carry cases – I recommend you get them.
Best Power Bank
Anker Prime Power Bank
With a 20,000 mAh capacity and 200W max output, this is the smallest and most powerful power bank on the market, perfect for charging smartphones, tablets, and laptops.
Anker Prime is a new ecosystem of portable chargers and power banks perfect for remote working and travel. The powerful devices work wonderfully individually but create an unparalleled charging experience when combined.
The Anker Prime 20K Power Bank is their most powerful, with a 20,000 mAh capacity capable of charging an iPhone 15 Pro Max four times, a Samsung Galaxy S23 Ultra five times, an iPad Pro 12.9” twice, and a MacBook Pro once.
The power bank has two USB-C ports and a single USB-A port. It features a powerful 200W maximum output using both USB-C ports simultaneously, allowing you to charge two laptops. The USB-A port has a 40W to 65W max output.
The Anker Prime Power Bank has a tremendous capacity in a small package. The power bank is 5” tall, 1.96” wide, and 2.15” deep and weighs 1.19 pounds. It’s not a power bank you can stuff into your pocket, but it easily packs in a tech or laptop bag.
The integrated Smart Display is unique among power banks. The full-color digital display provides information about the remaining battery percentage, the time until the power bank is recharged, and the power output of all the ports.
When paired with the Anker Prime 67W Charger, you can charge the Prime Power Bank in a few hours. You can charge three devices simultaneously with two USB-C ports and a single USB-A.

It’s a small unit for such a large capacity, measuring 5.4” long, 3.3” wide, and 1.2” thick and weighing just over a pound. It’s not small enough or light enough to carry in your pocket, but it’s certainly good enough for packing in luggage and gear bags.

Best Power Bank for Camping
Goal Zero Sherpa 100PD

Satechi Duo Wireless Charger Stand & Power Bank
This versatile device is a wireless charger, power bank, and stand perfect for travel, although it’s mostly geared toward Apple users.
The Satechi Duo Stand and Power Bank has a 10,000 mAh battery capable of charging an iPhone 15 Pro Max twice, a Samsung Galaxy S23 Ultra twice, and barely one charge for an iPad Pro 12.9”.
It’s a curious 3-in-1 device that is universally compatible with many rechargeable devices. First, the power bank features a single 18W USB-C port capable of charging any smartphone or other device.
Second, the top of the power bank tilts, creating a portable stand. A 10W Qi charger is integrated into the stand for charging any compatible smartphone. However, the stand is only strong enough to support a phone – touching the screen while in the stand pushes the stand flat against the power bank.
Finally, raising the power bank’s stand into place reveals a 5W Qi charge integrated into the base. This charger is perfect for Apple AirPods Pro 2 and trickle smartphone charging.
The 3-in-1 device’s small size is impressive considering the features. It measures 5.12” long, 2.83” wide, and 0.87” thick. Weighing just 10.2 ounces, it’s an ultraportable power bank that fits in your pocket.

The integrated Qi charger is great for compatible phones that include more than just the iPhone, but it only includes iPhone 11 and older models. The Qi charger is not compatible with the newer MagSafe iPhones.
The power bank has a single 12W USB-A port, a single 18W USB-C port, and a 5W Qi charger.
At 6.4” long, 2.9” wide, 0.7” thick, and at just 10.9 ounces, it’s a super portable power bank that slides into any zippered pocket or tech pouch.
The Satechi 165W 4-Port Charger is a great companion to this power bank. Depending on how many are used simultaneously, the ports range from 100W to 30W max output. The charger includes a wall plug and a stand for desktop use.

The Mophie Powerstation has a 10,000 mAh capacity and can charge an iPhone 15 Pro Max twice, a Samsung Galaxy S23 Ultra twice, and barely one charge for an iPad Pro 12.9”.
The power bank has a single 18W USB-C port and a single USB-A port. You can charge two devices at once, and the 18W output of the USB-C will charge an iPhone in about an hour.
