The Belkin BoostCharge Slim Magnetic Power Bank 5K in sand is a light, slim backup battery for keeping a phone going through long days away from a charger. Its 5,000 mAh battery is rated by Belkin for up to 25 hours of additional video playback on an iPhone 17 Pro, and the sand finish offers a softer alternative to black or white. Magnetic attachment aligns the phone for wireless charging at up to 7.5W. It supports Qi2-compatible devices, including iPhone and Google Pixel 10 models. The single USB-C port handles input and output. It delivers up to 15W to one device, or it charges two at once with up to 7.5W over USB-C and 5W wireless shared. Pass-through charging keeps your phone charging wirelessly at up to 7.5W while the bank recharges over USB-C at up to 15W. At 102 x 71.6 x 10.6 mm and 119 g, it sits comfortably in a pocket, works through MagSafe-compatible cases up to 3 mm thick and leaves the camera clear. Four status LEDs show remaining charge, SmartProtect safety features manage temperature and power spikes, and it is TSA carry-on compliant for air travel.
