The Icemag 3’s kickstand allows you to prop up your phone as it recharges. | Image: Cameron Faulkner / The Verge I’ve been testing compact, magnetic Qi2 power banks that can snap onto your phone for an upcoming buying guide. They make recharging much easier than bringing along a huge bat tery that weighs down your bag. One of my favorites so far is the Sharge Icemag 3, a 10,000mAh model that can wirelessly output 25W to iPhone 16-series phones and newer models. It also offers a built-in kickstand and a 35W USB-C cable that doubles as a lanyard, plus a USB-C port for passthrough charging. For a limited time, Amazon Prime subscribers can get it in either white or black for $69.90 ($10 off), and Sharge will include a basic 60W USB-C cable for free when you add both items to your cart. Alternatively, you can get the Icemag 3 for $2 less (sans the free cable) through Sharge’s own storefront. Using code ICE15 will knock it down to $67.92. Sharge Icemag 3 Power Bank Where to Buy: $79.9 $69.9 at Amazon (black, with Prime) $79.9 $69.9 at Amazon (white, with Prime) $79.9 $67.92 at Sharge (with code ICE15) I’ll save my detailed charging speed test results for a later date, but I’m impressed so far with the Icemag 3. While it’s thicker than some other Qi2 power banks, the build quality is stellar, and it’s speedy when it comes to both wired and wireless charging. I also adore its see-through window, which showcases an LED-packed fan that keeps the battery cool while it recharges my gear. Plus, a free USB-C cable is a nice little gift. ...read more read less
