CNN —  

As vaccines roll out all around the globe, some may be finally thinking about traveling again. And in case you’ve forgotten, traveling often brings about 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’s tough to figure out what kind of mobile chargers 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 batteries that contain them 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).

We found the best battery packs that are within FAA regulations so you can keep your smartphone, tablet, laptop or headphones juiced up during long airplane rides. 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. So 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.
