Travel often means long days for both you and your electronics. The best way to keep your devices charged throughout usage is by using a power bank. But, it can be tough to figure out what kind of mobile chargers fit within the Transportation Security Administration or Federal Aviation Administration’s rules so they won’t get taken away during check-in or at the security checkpoint.
All battery packs face very strict guidelines for air travel. Lithium-ion (rechargeable) batteries and portable batteries that contain lithium-ion can only be packed in carry-on baggage. They’re limited to a rating of 100 watt hours (Wh) per battery. With airline approval, you can bring two larger spare batteries (up to 160 Wh).
Here are our favorite battery packs that are within the FAA and TSA’s rules so you can keep your smartphone, tablet, laptop or headphones juiced up during long airplane rides. Whether you need a boost to keep binge-watching your favorite series or keep up with calls before boarding, these portable chargers will have you covered.
This top-rated battery pack from Anker packs the most power you’re allowed to take on a flight. It features a 45-watt USB-C port to charge your laptop back to full battery and 15-watt USB ports to charge smartphones and other small devices. The extra battery itself charges quickly and will reach a full charge in less than three and a half hours. It comes with a 60-watt USB-C wall charger and USB-C cable as well so you’re equipped with everything you’d need. It’s on the pricier side, but the speed at which it can repower your devices and the included wall charger and charging cable make the battery worth the splurge.
We like this pick from Anker because of the low price and slim design. It’s super lightweight and easy to slip into a purse, backpack or pocket. It features trickle charging mode so you’re able to safely charge smaller devices like your earbuds. You’ll need to get your own charging cables, as the only one included with the battery is a Micro USB to recharge the battery (it’s also rechargeable via the USB-C input port, but you’ll need your own cable). It’ll take 5.5 hours to recharge if you use a 10-watt wall charger. Overall, the slim design makes this a great pick for super-convenient portability.
After testing, this was our pick as the best overall portable chargerand it’s also perfect for travel. It boasts an impressive 13,000mAh, which is enough to charge an iPhone 11 two and a half times. In our testing, this small but mighty — and affordable — charger packed a ton of value in its three ports.
