Shoppers love it, calling it “a travel essential” and “a lifesaver on the go.” Haiara Magnetic Power Bank, $24 (was $92) at Amazon Why do shoppers love it? This power bank is smaller than most of the latest iPhones and features an incredibly powerful magnet that’s compatible with caseless phones and MagSafe cases. Simply slap it onto the back of any compatible phone or case, and watch it transfer its power quickly and efficiently, saving your phone’s battery from dipping into the red. Its 10,000 milliampere-hour battery can charge an iPhone 17 to full 1.5 times, but older models can be charged to full as many as two times. You can even continue to use your phone as it charges magnetically, and it won’t weigh your phone down too much considering it’s so small. Of course, it doesn’t just power devices up through its magnet. There’s an input for both USB-A and USB-C, which can all be used simultaneously along with the MagSafe charger. “It’s fast, compact, and reliable,” one shopper said. “The size is perfect — small enough to slip into a pocket or purse, but powerful enough to recharge my phone twice with battery to spare.” Aside from being safe for air travel, this charger also includes a myriad of safety features, including overcharge, overcurrent, overvoltage, and short circuit protection.
