Air travel can be stressful and exhausting, especially when you pack electronics like smartphones and battery packs into your carry-on bag. It’s tough to figure out what kind of mobile devices are approved by the Transportation Security Administration or Federal Aviation Administration, so they won’t get taken away during security check-in.
All battery packs face very strict guidelines for air travel. Lithium ion (rechargeable) batteries and portable rechargers that contain them can only be packed in carry-on baggage. They’re limited to a rating of 100 watt hours per battery. With airline approval, you can bring two larger spare batteries (up to 160 Wh).
We found the best battery packs that are within FAA regulations, so you can keep your smartphone, tablet, or laptop juiced up during long airplane rides. Don’t worry, the TSA won’t take away any of the batteries listed below, so you can use them to keep your mobile devices charged and ready to go.
The TravelGo Portable Charger is a sleek and lightweight battery pack that’s perfectly compact to include in your carry-on bag. But don’t let its size fool you. It’s a small but mighty battery pack that pumps out 10,400mAh of power at 5 volts for fast charging iOS and Android smartphones and tablets. In fact, feel free to charge two devices at the same time with the pack’s dual USB-A ports.
While it only includes a micro-USB cable for charging, TravelGo encourages customers to use the charging cables that came with their own smartphones to protect from short circuits and over-voltage, so your mobile device will last longer without overcharging or diminishing its battery life. On Amazon, the battery pack has a 4.6- out of 5-star rating with more than 90 reviews.
This top-rated battery pack from Anker packs the most power you’re allowed to take on a flight. The Anker PowerCore+ comes in at just under the FAA’s 100-Wh battery restriction, with 26,800mAh (milliAmp hour) of power and a 3.7-volt standard lithium cell. The battery pack provides fast charging for smartphones and tablets, while it can even give some juice to premium laptops like the MacBook Pro via a USB-C port.
The Anker PowerCore+ comes with one USB-C port and two USB-A ports, which are perfect for travelers with an iOS or Android mobile device — such as the iPhone XS, iPad Pro, Samsung Galaxy S10, Google Pixel 3, and more. The battery pack includes a wall charger, micro-USB cable, USB-C cable and a handy travel pouch. It has a 4.3- out of 5-star rating on Amazon with nearly 1,000 reviews and is listed as an “Amazon Choice” .
If you’re not concerned with having the most power ever, Anker’s PowerCore 10000 is one of the lightest and smallest external batteries on the market. It can provide about three and a half charges to an iPhone 8 or two and a half charges to a Galaxy S8. It provides universal high-speed charging, and has become one of my travel musts. And I’m not the only one who loves it. The Anker PowerCore 10000 boasts a 4.5-star rating with almost 12,000 reviews on Amazon.
With a 4.2- out of 5-star customer rating, this portable and compact battery pack is ideal for traveling because it’s within the FAA’s carry-on flight regulations. It features a 10,000mAh polymer battery with two USB-A ports for dual charging iOS and Android smartphones and tablets. The charging battery lives inside a rugged and slim plastic case that’s designed to regulate temperature to reduce overheating and voltage fluctuation.
In addition, the Belkin Pocket Power features four LED indicator lights to show power level status at a glance. And when the Belkin Pocket Power runs out of juice, just plug the battery pack into an outlet with a USB wall charger and its included micro-USB charging cable.
For less than $35, the “Amazon Choice” Jackery Bolt offers the best bang for your buck as an ultra-portable battery pack for just about any iPhone or Android device. In fact, this battery pack is so compact that it includes two built-in charging cables; one Lightning for iPhone or iPad and one micro-USB for Android. However, if your Android device doesn’t have a micro-USB charging port, the Jackery Bolt also includes one USB-A port, so you can simply plug in your own charging cable to get some quick juice on the go.
The battery pack is powerful, with its 6000mAh power bank, while its aluminum body is compact and smaller than a standard credit card. It also includes a micro-USB port for charging when plugged into a wall charger (which is not included), and the Jackery Bolt has a handy, built-in LED flashlight for emergencies — which is a nice touch for traveling.
