Butchering day, a good fishing trip or a big batch from the dehydrator all end the same way: a pile of food that needs packing for the freezer or the pantry shelf. A vacuum sealer makes that job faster and neater, and you don’t have to spend much to get started. The MEGAWISE Vacuum Sealer (model VS6621) is a compact, budget-friendly countertop sealer. Here’s what it does, what Megawise’s listing says, where it falls short, and how to use vacuum packing safely.

Dry, Moist, Manual and Seal-Only Settings
The VS6621 has settings for both dry and moist foods. Use the dry setting for solid foods without liquid. The moist setting is meant for meat or fish, and Megawise says it removes small amounts of liquid (up to about 10 ml) before it seals. There’s also manual vacuum control, so you decide how much air comes out. That’s useful for soft or marinated foods you don’t want crushed. A seal-only option seals a bag without vacuuming, which is handy for resealing snack bags.
A note on the control panel: the Amazon listing’s text and its photos don’t describe the same panel. The photos show a newer layout than the bullets describe, so it isn’t clear which revision ships. Check the panel and the manual on the unit you receive before your first big sealing session.
Speed, Bags and Accessories
A typical cycle takes about 10 to 20 seconds per bag, and the 12-inch sealing wire handles standard vacuum-sealer bags. The built-in cutter lets you trim bags to size or make custom-length bags from a roll. The starter kit includes 10 vacuum bags to get you going, plus a hose for vacuum canisters and jar attachments. The canisters and jar attachments are sold separately, so budget for them if you want to vacuum-seal jars of dry goods.
At 15.2 inches long and only about 4 inches wide, it doesn’t need a permanent spot on the counter. It fits in a kitchen drawer between uses.
What to Seal on the Homestead
- Meat and venison: portion butchering day into meal-size freezer packs
- Fish: pack fillets for the freezer
- Dried foods: dried fruit and jerky from the dehydrator
- Bulk dry goods: rice and beans bought in bulk, split into smaller packs
- Pantry odds and ends: reseal snack bags with the seal-only option
Food Safety: Vacuum Sealing Is Not Canning
Vacuum packing removes air, but it doesn’t make perishable food shelf-stable. According to Clemson Cooperative Extension’s Home & Garden Information Center (HGIC 3865, Vacuum Packaging Foods at Home):
- It’s not a substitute for canning or other safe processing of perishable foods stored at room temperature.
- Refrigerate or freeze. Perishable vacuum-packed foods still need to be refrigerated (34–40°F) or frozen (0°F or below).
- Thaw in the refrigerator, never on the counter.
- Why it matters: low-oxygen packages can let C. botulinum grow in low-acid, moist foods kept at room temperature.
Think of the sealer as a way to pack food neatly for the fridge, the freezer or the dry pantry, not as a way to preserve perishables on the shelf.
Honest Limitations
- Budget build. It’s all plastic, with no bag holder or bag hooks.
- Suction. An independent lab test by ShouldIt.com measured noticeably less suction than Megawise advertises, and dense dry foods kept a little residual air. It’s fine for everyday freezer packs, but if you’re sealing a whole deer or hog in one session, look at a stronger machine.
- Wear parts. The foam gaskets and sealing strip wear over time. Megawise sells replacements.
- Panel mismatch. The listing’s photos and text describe different control panels, so check the unit you receive.
- Accessories cost extra. Canisters and jar attachments for the hose are sold separately.
Who It’s For
Homesteaders and small households who want an inexpensive way to start vacuum sealing: portioning meat, venison and fish for the freezer, packing dried fruit and jerky, and splitting bulk rice and beans into smaller packs. It’s also a good fit for small kitchens, since it stores in a drawer. If you put up large amounts of meat at once, you’ll want a heavier-duty sealer.
The Bottom Line
The MEGAWISE VS6621 is a simple, compact and affordable vacuum sealer for putting up food in small batches. You get dry and moist food settings, manual vacuum control, a seal-only option, about 10–20 seconds per bag, a 12-inch sealing wire, a built-in cutter and a starter kit with 10 bags and a hose. Keep its budget build in mind, and keep vacuum-packed perishables in the fridge or freezer.
