USB Rechargeable Portable Vacuum Sealer

This Vacuum Sealer from Velleora Home Decor draws the air out of a bag and seals it, which is what genuinely extends the life of food - oxygen is what turns cheese, meat and cut fruit, and removing it buys days in a fridge and months in a freezer.

It also solves freezer burn, which is simply air reaching the surface of frozen food. A vacuum seal presses the bag against the food, so a steak or a loaf comes out months later without the grey dried patches that lead to it being thrown away.

Being cordless and rechargeable makes it usable at the point of packing rather than tethered to a socket behind a worktop. It suits freezer portioning, sous-vide and marinating, which works considerably faster under vacuum. Make sure the bag mouth is clean and dry before sealing - moisture or grease on the seal line is the main cause of a failed seal. Charge indoors.
