1. EGO Power+ ST1521S

31+UlfjuOpL. SL500

EGO has been testing the limits of cordless technology since it started operations back in 1993.

Today, it is known in 65 countries as one of the biggest names in the design and manufacture of innovative power tools.

The brand took another big leap forward with the Power+ ST1521S.

This weed wacker runs on the industry-leading EGO Arc Lithium battery, delivering the power of gas without the noise, hassle, and carbon footprint.

It also features the super lightweight carbon fiber shaft, which is a gamechanger in the string trimmer technology.


Many things can be said about the EGO Power+ ST1521S.

Here are some of the highlights to help you decide if this is the right weed wacker for you:

  • Powerful Battery

EGO’s Arc Lithium 56V 5.0 Ah battery offers a different level of performance and is aptly coined “Power Beyond Belief.”

All EGO outdoor power tools use the same battery.

Therefore, if you have a spare from another EGO equipment, you can go for the basic configuration of this weed wacker and save on cost.

Each EGO battery is designed with unique arc technology that keeps the cells cool.

What’s great about this is that it prolongs battery life even under extreme conditions and heavy use.

Covered by three years of limited warranty, you can expect to get the most out of this product.

The Power+ ST1521S comes with an integrated fuel gauge that tells you how much power is left.

It would take around 40 minutes to charge the battery using the Rapid Charger and 100 minutes with the Standard Charger.

  • Carbon Fiber Shaft

Another key feature of the Power+ ST1521S 1 is its carbon fiber shaft.

As you may already know, carbon fiber is very durable and lightweight, making it one of the most preferred materials today.

EGO is one of the first brands to successfully introduce it to the home power tools space.

It answers one of the biggest challenges in using power trimmers, which involves weight distribution.

The design and minimal weight of the Power+ ST1521S reduces the stress on your back even after an hour of use.

Aside from having key ergonomic advantages, the carbon fiber shaft is also virtually unbreakable.

In fact, it is so strong that EGO offers a lifetime warranty on it.

  • Powerload Head

Despite all the innovations already discussed, the Powerload Head is, perhaps, what makes the Power+ ST1521S truly unique.

This feature allows you to feed a new line into the trimmer head without taking it apart or winding it manually.

All you have to do is pull the 0.095-inch line through a hole and then push a button at the back of the motor.

The power trimmer automatically ratchets the line up evenly.

What’s more, it does this at a safe speed, protecting you from being flogged as you load a new line.

While EGO is not the only brand that offers this technology, its version is definitely one of the most reliable.

  •  Brushless Motor

Adding to its long list of great features is this weed wacker’s high-efficiency brushless motor.

It registers a very quiet 80 dBA on the SPL meter, enough to let you trim your lawn before the sun is up without disturbing the neighbors.

The vibration caused by the motor is also minimal.

Hence, you can use the power trimmer continuously without feeling too much stress on your hands and arms.


  • Easy to load a new line
  • Durable and lightweight carbon fiber shaft
  • Excellent weight distribution
  • Long-lasting battery
  • Low noise and vibration


  • Small front handle
  • Needs more batteries for very large lawns
