Power banks or portable battery packs can be life savers when traveling. Whether you use them to charge your phone or laptop, a power bank is a must-have accessory if you’re going to be away from a wall outlet for a long time. As such, you might be interested in the best high-capacity power banks for travel.

A standard power bank may only be able to charge your smartphone or other low-powered devices a couple of times. However, a high-capacity power bank may even charge bigger devices like laptops multiple times. Along with a high capacity, it’s also important to have a high wattage for power output to charge large devices. We’ve made a list of some of the best power banks that fulfill both these needs to help you while traveling.
