USB-Powered Mason Jar Vacuum Sealer

A lightweight (approx. 280g), handheld vacuum sealer purpose-built for standard-mouth mason jars. Dimensions: 10.4 × 9.4 cm. Housing made from heat-resistant, wear-resistant ABS plastic — BPA-free and food-safe. Driven by a 7.4V motor delivering 3.5L/min airflow at 5W power draw. Operates quietly at 55 dB. Powered by a 1200mAh internal battery charged via USB-C — enabling full portability without tethering to mains power. Includes 10 sealing covers, bottle opener, USB-C cable, and retail colour box. To use: place food in jar, secure iron lid, position sealer over mouth, press down firmly, then activate with the dedicated button. The display indicates elapsed vacuum time and current battery level. For best results, run for ≥20 seconds. The resulting vacuum slows spoilage, retains volatile aromas, prevents freezer burn, and maintains crispness in produce or crunch in snacks. Especially suited for UK households with limited kitchen space, students in shared flats, or those prioritising low-noise appliances. Compatible only with standard-mouth glass jars and their corresponding flat iron lids — not wide-mouth or plastic-lidded variants.
