The RAVPower AC Outlet Portable 100W Charger is an ideal travel gadget because it has ports for pretty much everything. In fact, this portable charger even has an AC outlet, so you can plug your wall plugs directly into it. That means you can work wherever you want without having to worry about your proximity to an outlet. This power bank is powerful, too, as it can charge your MacBook about one and a half times. Not only that, but it can give your iPhone more than seven full charges. With the ability to charge three devices at one time, this portable charger provides a maximum output power of 100 watts. Finally, the 27,000 mAh battery capacity can fully recharge in just about five hours.
