The Belkin BoostCharge Slim Magnetic Power Bank 5K is a slim backup battery for people who need their phone to last through a full day away from a desk. At 102 x 71.6 x 10.6 mm and 119 g, it stays attached to the back of a compatible phone and still fits in a pocket. The magnetic alignment ring holds it in place without blocking the camera, and it works through MagSafe-compatible cases up to 3 mm thick. The 5,000 mAh cell delivers up to 7.5W wirelessly or up to 15W through the single USB-C port. Belkin rates it at up to 25 additional hours of video playback on an iPhone 17 Pro. With a phone on the magnetic pad and a second device on USB-C, output is shared at up to 7.5W (USB-C) plus 5W (wireless). Pass-through charging lets you recharge the bank over USB-C while it keeps charging your phone wirelessly at up to 7.5W. Four status LEDs show the remaining charge in 25% steps. SmartProtect guards against excess temperature and power spikes, and the unit ships pre-charged. The housing uses at least 85% post-consumer recycled plastic, and the packaging is plastic-free. Belkin covers the power bank with a 2-year warranty and a $2,500 Connected Equipment Warranty. For field staff, travelling teams and anyone who relies on a phone for work, it is a small, light way to add a meaningful top-up without carrying a cable-bound brick.
