Electric jar opener: what it is, how to choose, and 3 that work
An electric jar opener is a battery-powered unit that sits on top of a jar and twists the lid loose when you press a button. It grips the jar and turns the lid by itself, so your hands only have to set it in place and press. You'll also find it sold as an automatic or battery jar opener.
Also sold as: automatic jar opener, one-touch jar opener or battery jar opener.
How to choose an electric jar opener (automatic jar opener, one-touch jar opener)
An electric jar opener takes the grip and the twist out of opening a jar: you set it on the lid, press a button, and lift it off once the lid is loose. Models differ in which jars they fit and in how much handling they still ask of your hands.
- Lid range. Each model lists the smallest and largest lid it can grip. Most cover ordinary grocery jars; small bottle caps and very wide lids are where they part ways. Measure across the lids you open most often and compare before you buy.
- Single press or press-and-hold. Some run after one press; others only run while you keep the button down. Holding a button for several seconds is hard when your fingers are weak or sore, so check which kind you're getting. A large, raised button is easier to find and press than a small flush one.
- Batteries or rechargeable. Many run on AA batteries, and the battery hatch can turn out to be the fiddliest part of the whole thing. Rechargeable models skip the hatch but need a charging cable within reach. If a battery model starts stalling on lids it used to open, try fresh batteries before anything else.
- Weight. You lift the unit onto every jar, so check the weight if lifting or a shaky hand is part of the problem. A heavier unit isn't automatically a stronger one.
- What it won't open. It turns screw lids and screw caps. Push-and-turn child-resistant caps, flip-tops and cans all need a different tool.
Who should skip it. If you can turn a lid once the seal is broken and only the first twist defeats you, an under-cabinet opener or a rubber gripper costs much less and needs no batteries. And if most of what you struggle with is bottles, pill caps or cans, this won't help with them.
What the numbers mean
- Lid range (mm)
- Small bottle caps and very wide lids are where models differ most, so check the range against the jars you actually open.
- Power
- Battery hatches can be fiddly to open with weak fingers; a rechargeable model avoids that but needs a charging cable within reach.
- Weight
- You lift it onto every jar, so a lighter unit is easier to place with one hand or a shaky one.

Automatic electric jar opener for 1.2–3.5" lids
Electric jar opener
$21.99 price as of Sep 27, 2026 at 4:47 pm ET
Check price on Amazon (opens new tab)- Why it works
- Set it on the lid and press the button for 3 seconds: it clamps and turns the lid itself, and you don't hold the opener while it works. Reviewers with arthritis use it for everyday jars.
- Who it won't suit
- It only takes lids from 1.2 to 3.5 inches and won't work on plastic lids such as mayonnaise jars; one owner learned that cheap batteries aren't strong enough.

Electric jar opener
$21.74 price as of Sep 27, 2026 at 4:47 pm ET
Check price on Amazon (opens new tab)- Why it works
- A higher-torque motor for tight, vacuum-sealed lids: one press and the adjustable jaws clamp and turn the lid, with no grip or twist from you.
- Who it won't suit
- The maker says to hold it steady while it runs and that it is for screw-top glass jars only, not cans or plastic containers.
What reviewers report
Reviewers who bought it when arthritis or wrist fatigue turned factory-sealed lids into a painful job say the motor does the first turn for them. — Our summary of customer reviews on Amazon · read the reviews (opens new tab)
nubadam electric jar opener for 1.2–3.5" lids
Electric jar opener
$21.49 price as of Sep 27, 2026 at 4:47 pm ET
Check price on Amazon (opens new tab)- Why it works
- Place it on the lid and press the button: two vice grips clamp lids from 1.2 to 3.5 inches and the motor does the twist. One reviewer with limited grip after cut tendons uses it.
- Who it won't suit
- It takes two AA batteries that aren't included, and the maker doesn't recommend it for plastic jars holding liquids.
What reviewers report
Reviewers describe the specific losses they are working around: arthritis in the thumbs bad enough to weaken a grip, and cut tendons that left one hand with little strength. — Our summary of customer reviews on Amazon · read the reviews (opens new tab)
Guides where we recommend electric jar openers
Questions people ask about electric jar openers
Do electric jar openers work on vacuum-sealed jars?
Yes, that's the main job they're built for. On a very tight seal the motor can stall; fresh batteries often fix it, and so does letting air in first by levering the edge of the lid with a spoon handle, if you can manage that. Once the seal is broken, the lid turns easily.
Can you use an electric jar opener with one hand?
Mostly, yes. You place it on the lid with one hand and press the button, and the unit holds the jar while it turns the lid. Stand the jar on a non-slip mat or a damp cloth so it can't slide while the opener grips it.
What size jar lids does an electric jar opener fit?
It depends on the model, and the listing should state the range. Most handle standard grocery jars; the ones that trip people up are small spice and sauce bottles at one end and wide pickle or peanut butter jars at the other. Measure across the lids you open most and compare.
Can an electric jar opener open pill bottles or child-proof caps?
Not child-resistant caps, which need pressing down while you turn; the opener only twists. It can open ordinary screw-cap bottles if the cap is inside its size range, so check the minimum lid size, since small caps may fall below it. A pill bottle opener is the tool made for child-resistant caps.
