Foodsaver 4840 2 In 1 Vacuum Sealing System Review


Let’s get real here; sometimes, we become too purchase-happy whenever we do the grocery rounds. We buy plenty of perishables like vegetables, fruits or meats that we can’t finish off right away.

We also cook larger-than-normal quantities of food, or throw parties and deal with a load of leftovers later. And because of this, a a lot of food goes to waste.

However, modern technology has given us a solution for all that wastage. The FoodSaver 4840 is capable of maintaining the freshness of your food items in a longer manner so you can enjoy it later.

This particular innovation will help homeowners keep their food fresh for a time while still sustaining their usual flavors and most especially, the nutrition these foods provide.


Oxygen oxidizes food, resulting into spoilage will be the thing of the past. With a vacuum sealer, your items will remain fresh for a long period of time.

The Foodsaver 4840 has the following features:

  • It has a fully-automatic operation to help users pack foods without any hassles.
  • It has an integrated retractable handheld sealer.
  • It has Moist/Dry settings.
  • It features a removable drip tray and is dishwasher-safe.
  • The whole package includes roll storage and a bag cutter, bag roll, assorted heat-seal and zipper bags.
  • Is backed-up by a 5-year limited warranty.


The device works fast, is practical and cost-effective as compared with similar models and prices available in the market today. Its 2-in-1 scheme makes the device a significantly effective machine when it comes to securing a selection of plastic bags. Its handheld removable sealer offers manageable operations using containers and bags with zip functions, and these items can be a challenge to handle when it comes to employing them to a device like this.

The device works in an automatic manner, meaning once it perceives the presence of a plastic bag within its vicinity, it begins its work of removing the air and securing the bag without too much manual assistance. It has user-friendly buttons too which makes handling the device a cakewalk. They do not feature a complicated format that even novices can easily hack the procedures.

The presence of the tray was convenient too, since clean-up is faster and users will be able to avoid leakage on their kitchen surfaces during the sealing process.

The 4840 also includes a jar sealer which comes in handy for homeowners who love making their own batches of jams, jellies or the bulk of a fruit/veggie harvest or purchase.

The pulse feature is great when it comes to sealing flakey or powdery foodstuff. You won’t have to fret over broken cookies or loads of crumbs anymore. In addition, the whole package is assembled in full so you won’t have to do any additional work on it.

The device comes with a 5-year limited warranty, which is another nice bonus from the company.

Other than its food-packing abilities, users can also employ the device for packing non-edible items like silverware, jewelry, paper items and lots more. It is not only for the kitchen, it’s for your own protection of valuables too.


Now that we have discussed the pros, it’s now time to get into the cons. The 4840 was recounted by several users to be practically inefficient when it comes to sealing the bags and storing liquid-based food items. Some individuals also thought that the device was unyielding.

The creators, engineers behind the device surely must have made the unit with domestic use in mind, since it is not that capable of securing items by the bulk. It needs plenty of cool-down periods after an extended run of sealing procedures.

However, some have argued that this is to ensure that the device will continue to do its good work and last longer. Thus, if you want to pack by the bulk, keep in mind to invest on an industrial-grade vacuum sealer.

The device’s automatic detection feature can be a bit challenging to employ. Sure, the unit did have a straightforward control panel, but its automatic detection feature might prove to be a handful for some, especially beginners.

Several who have used the product said that learning how to position and feed the bag to the sealer took them some time to get the hang out of it.

To prevent ruining the rest of those expensive FoodSaver plastic bags, do take the time to fully study the instruction manual provided.

The unit, like other FoodSaver devices, only takes in the brand’s own line of plastic bags. And they can be pretty expensive.


The most prevailing downsides of the FoodSaver 4840 were its supposedly “need for plenty of cooling-down after bulk sealing processes” and its challenging automatic detection.

The former can be easily solved by investing on an industrial-use vacuum sealer since the device being discussed is designed for domestic use only.

As for the latter, read the manual extensively to prevent wasting more plastic bags and once you get the hang of it, you will learn that the device is really a good buy.

You will save money, keep your edibles longer and avoid so much spoilage. It is also lightweight, so you can tuck it anywhere you wish in the kitchen. Other than dealing with food, you can also secure your valuables using the device.
