In the midst of summer in the northern hemisphere, many of us are enjoying the warm weather outdoors. However, it’s frustrating to run out of battery mid-hike or during a festival. To avoid this, consider investing in a portable charger like the Anker 334 MagGo Battery, currently on sale for $31.49, a 21 percent discount from its usual $40 price. This power bank is MagSafe-compatible and can charge an iPhone 15 Pro 1.7 times and an iPhone 15 Pro Max 1.2 times. It provides 7.5W of wireless charging and has a strong magnetic force to stay attached to your phone. Keep in mind that it only works with iPhone 12 and newer models, and if your case isn’t MagSafe-compatible, it will need to be removed. While wireless charging may be slower than wired, it’s a convenient option for camping trips.
