About Product Overview

The M18 HOTSHOT Jump Starter runs off the same M18 battery platform as the rest of your Milwaukee lineup, so there's no separate charger or dedicated battery to keep track of - if you've got M18 tools, you've already got the power source for this. It delivers 2000 amps to get a dead vehicle battery running again, with reverse polarity protection built in to guard against a bad connection during a rushed roadside jump.

Switch between automatic and manual modes depending on the situation, and count on it whether you're working in the driveway, the shop, or out in the field. It's a solid pick for anyone who runs a fleet, works on equipment regularly, or just wants a jump starter that doesn't need its own charging routine.

  • 2000 amp output
  • Runs on M18 lithium battery (sold separately)
  • Automatic or manual operation
  • Reverse polarity protection
  • Boxed packaging
  • Made in Vietnam

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
