We’ve all been there: One minute, you’re listening to your favorite podcast or playlist, counting on the maps app to get you home, and the next, your phone battery says 5 percent. The best solution?

If you're wondering why this charger boasts a 4.3 out of 5-star rating with more than 13,000 (!) reviews, it’s about as compact as a lipstick tube and has an extended charging dock that can fit most iPhone models—even when the phone has a thick silicone case on it. The battery can also bring your iPhone (or AirPods) to a full charge, according to the manufacturer, and includes a power bank and USB cable for when the iWalk needs a recharge itself. (The LED lights at the bottom of the dock will let you know when the charger needs to be plugged into the power bank.)
