The Belkin BoostCharge Slim Magnetic Power Bank 5K is a pocket-friendly backup battery for anyone whose phone has to last the full working day. It holds 5,000 mAh, which Belkin rates for up to 25 hours of additional video playback on an iPhone 17 Pro. The black finish suits professional use. The bank attaches magnetically for aligned wireless charging at up to 7.5W and supports Qi2-compatible devices, including iPhone and Google Pixel 10 models. Its single USB-C port handles input and output. It delivers up to 15W to one device, or it charges two at once, sharing up to 7.5W over USB-C with 5W on the wireless pad. Pass-through charging keeps your phone charging wirelessly at up to 7.5W while the bank recharges over USB-C at up to 15W (5V 3A or 9V 1.67A). It measures 102 x 71.6 x 10.6 mm, weighs 119 g and works through MagSafe-compatible cases up to 3 mm thick without blocking the camera. Four status LEDs show remaining charge, SmartProtect safety features guard against temperature and power spikes, and the bank arrives pre-charged. It is TSA carry-on compliant, so it can travel in cabin baggage. The housing uses a minimum of 85% post-consumer recycled plastic, and the bank ships in plastic-free packaging with a 2 ft (0.6 m) USB-C to USB-C cable. Belkin provides a 2-year warranty and a Connected Equipment Warranty of up to $2,500.
