  • Great replacement charger!
Purchased as a replacement to charge the battery for my Worx HedgeTrimmer. Works great! Charges fast, and the charge appears to last. Very easy to use, fits the battery perfectly. Seems like it will last me a great while. Perfect for what I needed it for and great value for the price. Highly recommend if you're also looking for a replacement to charge this type of battery. ... show more

  • Great product
Great replacement for the original Worx battery. Charges super quickly and the charge lasts even longer than the original one- even when it was new. Definitely recommend!

  • Great replacement
We bought this as a replacement charger since the original charger broke. My husband says it works well and the charge lasts a good while when using it for our lawn equipment. It was easy to use and a good value for the price paid. I would definitely buy this again if needed.
