This is a cordless lithium ion battery powered weed trimmer made by DeWalt. It's about 2 months old. This comes with the charger and the more powerful 40v 4aH battery. It is very powerful and has two power ranges for normal trimming or heavy duty use. As far as power I would put it up against a gas trimmer. Due to a shoulder injury I'm able to use it. These were $400 new. This is a cash sale. No scammers. Thanks. Please call or text with questions.
