It’s the middle of summer for those of us in the northern hemisphere, which means many of us are getting out and about to make the most of the warm weather. But there’s little worse than finding yourself mid-hike or with several more acts to go at a festival only to find your phone is out of juice. To help you stay in touch with friends and share envy-inducing photos on Instagram, you might need a <\/a>, and a solid Anker options is currently on sale.<\/p>\n The Anker 334 MagGo Battery with a 10,000mAh capacity is <\/a>. It typically costs $40.<\/p>\n Anker<\/p>\n<\/div>\n<\/div>\n This MagSafe-compatible power bank is on sale for $31.49. That’s 21 percent off the regular price.<\/p>\n<\/p><\/div>\n $31 at Amazon<\/a><\/div>\n<\/div>\n This model is a strong choice for iPhone users as it’s MagSafe-compatible. According to Anker, you’ll be able to charge an iPhone 15 Pro 1.7 times over and an iPhone 15 Pro Max 1.2 times thanks to its decently sized battery. The company also suggests that the power bank could add up to 22 hours of video playback time to an iPhone 14.<\/p>\n The power bank delivers 7.5W of wireless charging. It’s unlikely to easily budge from the back of your iPhone as it has 10N of magnetic force, which is more than Apple’s own MagSafe charger.<\/p>\n On the downside, you’ll need a compatible device to use this. The Anker 334 MagGo Battery only works with the iPhone 12 and later models. If you have a case that isn’t MagSafe-compatible, you’ll need to remove that first too. In addition, wireless charging is slower than simply plugging your phone in, but that’s perhaps less of a concern when you’re off camping for a weekend.<\/p>\n Follow <\/em>@EngadgetDeals<\/em><\/a> on Twitter and <\/em>subscribe to the Engadget Deals newsletter<\/em><\/a> for the latest tech deals and buying advice.<\/em><\/p>\n<\/div>\n![](\"https:\/\/s.yimg.com\/uu\/api\/res\/1.2\/rueqAMObekYcGWibfEAmbQ--~B\/Zmk9c3RyaW07aD03MjA7dz0xMjgwO2FwcGlkPXl0YWNoeW9u\/https:\/\/media-mbst-pub-ue1.s3.amazonaws.com\/creatr-uploaded-images\/2024-07\/0ca23410-4e7d-11ef-858f-d09b197a5208\")
