You grab a cordless trimmer on sale, get it home, and find out the box has only the tool. No battery, no charger. Now you're shopping again for a part that costs half the price of the whole thing. That's why it pays to search for a cordless string trimmer with battery and charger included. This guide is for homeowners with a small to medium yard who want to open the box and start trimming. Here are the 4 best cordless string trimmer with battery and charger kits in 2026, ranked by reviews and ratings. We read the listings and the reviews. We didn't test them ourselves.

What to Look For in a Cordless String Trimmer With Battery and Charger

Read the title for "tool only." Many Amazon listings for the same trimmer come in two versions: tool only, or a kit. Check that the title says battery and charger included before you click buy.

Voltage and amp-hours. Voltage is the power. Amp-hours (Ah) is how long it runs. A 20V or 24V kit handles a small yard and edging. A 56V kit cuts thicker grass and weeds and runs longer. A 2.0Ah battery is fine for a quick pass. A 4.0Ah battery gives you room to finish a bigger lot.

Cutting width. Twelve inches is plenty for flower beds and fence lines. Fifteen to 16 inches clears a lawn faster.

Weight and balance. You'll hold it for 15 to 30 minutes. A lighter 20V or 24V unit is easier on the arms. The heavier battery on a 56V model sits at the back to balance the head.

Warranty and battery system. A battery that fits other tools from the same brand is a real bonus. Look at the warranty on the battery too, since it's the part that wears out.

The 4 Best Cordless String Trimmer With Battery and Charger Kits in 2026

1. WORX WG163 20V 12" 2-in-1 Cordless String Trimmer and Edger

Best for: small to medium yards that need a trimmer and an edger in one tool.

Check Price On Amazon

This is the most reviewed cordless trimmer we found, with well over 28,000 ratings at 4.3 stars. It's a 20V, 12-inch trimmer that converts to a wheeled edger. The kit comes with two 2.0Ah batteries and a charger.

What makes it stand out: Two batteries in the box, so you can swap when one runs out. The Command Feed button lets you bump out more line without stopping, and the head pivots 90 degrees for narrow spots.

Good to know: It's a 20V tool, so thick weeds and tall grass will slow it down. It's best on lawn edges, not overgrown lots.

2. Greenworks 24V 12" Cordless String Trimmer / Edger with 2.0Ah Battery and Charger

Best for: a tight budget and a small lawn.

Check Price On Amazon

The cheapest kit in this list, and a long-time seller at 4.2 stars across more than 7,000 ratings. It's a 24V, 12-inch trimmer and edger with a 2.0Ah battery and a charger in the box.

What makes it stand out: The price and the adjustable design. It has a telescoping shaft and a 4-position pivoting head, and the listing shows a 3-year warranty on the tool and battery. The listing claims up to 40 minutes of runtime on a 2Ah battery.

Good to know: Prices on Amazon swing around for this kit, so check what you're actually paying. It's the lightest-duty trimmer here. Plan on short sessions with one battery.

3. EGO POWER+ ST1523S 56V 15" String Trimmer with 4.0Ah Battery and Charger

Best for: bigger lawns and thicker grass where a 20V trimmer struggles.

Check Price On Amazon

This is a step up in power. It runs on a 56V ARC Lithium system with a 4.0Ah battery and a charger, and it cuts a 15-inch path. It has a carbon fiber shaft and EGO's POWERLOAD head, where you press to wind new line instead of threading it by hand.

What makes it stand out: The power and the warranty. EGO shows 5 years on the tool and 3 years on the battery and charger. The 56V battery also fits EGO's mowers, blowers and other tools.

Good to know: It costs a lot more than the Worx. The 4.3-star rating comes from fewer reviews (around 430), and it's a fixed-length shaft.

4. EGO Power+ ST1611T 56V 16" String Trimmer with Telescopic Shaft, 2.5Ah Battery and Charger

Best for: people who want the highest-rated kit and an adjustable shaft.

Check Price On Amazon

The newest of the four, and the best rated at 4.6 stars. It has a 16-inch cutting swath, a telescopic carbon fiber shaft that adjusts to your height, POWERLOAD line loading and a 2.5Ah battery with a charger. The listing says up to 45 minutes of runtime.

What makes it stand out: The telescoping shaft. If you're tall or short, you can set it so you don't hunch. It's also the widest cut here.

Good to know: Only around 180 reviews so far, so the rating has less history behind it. It's the most expensive kit on this list, and the 2.5Ah battery is smaller than the one in the ST1523S.

How to Pick the Right Kit for Your Yard

  1. Small yard or townhouse lot: the Worx or the Greenworks. Both are light and cheap.
  2. Half an acre or more, or thick weeds: go with 56V. The EGO kits cut longer and stronger.
  3. Already own cordless tools? Check whether you already have batteries from the same brand. You may not need a kit at all.
  4. Keep the battery cool. Charge it indoors, not in a hot garage.
  5. Wear eye protection. Trimmers throw rocks and debris.

Frequently Asked Questions

How long does a cordless string trimmer battery last?

It depends on the battery and how hard you push it. Listings claim up to 40 to 45 minutes on 2.0 to 2.5Ah batteries, but heavy weeds and full throttle shorten that. Plan on less in rough grass.

Are cordless trimmers as powerful as gas?

The 56V models get close for normal yard work. A 20V or 24V trimmer is not a gas replacement for thick brush. For heavy brush, look at a bigger kit.

Is a 20V or 56V trimmer better?

56V is more powerful and runs longer, but it costs more. For a small lawn and edging, 20V or 24V is enough.

Can I use the battery in other tools?

Only with the same brand and voltage system. EGO 56V batteries fit EGO tools, and Worx and Greenworks work the same way with their own lines.

Final Thoughts

The Worx WG163 is our #1 for most people. It has the most reviews by a wide margin, two batteries in the box and an edger mode that covers the sidewalk too. If your yard is small and money is tight, the Greenworks 24V does the basics for less.

If you have a larger lot or thick weeds, step up to the EGO ST1523S for the bigger battery and 5-year tool warranty. Pick the ST1611T if you want the telescoping shaft and the highest rating, and you're fine with fewer reviews. If you're already buying batteries for a mower or blower, our lawn mower kit picks are worth a look first, since one battery system can run all of them.
