Portable Car Jump Starter Compatible with Makita 18V- 11AWG Heavy Duty Jump Starter Cable 1 2FT for Car

This Makita 18v jump starter is nicely made and has a look and feel of quality. No complaints there. The main issue is it requires that the battery you want to jump start is not completely dead. There is 0v coming out of the jumper cable clamps with only the Makita 18v battery inserted. That means you can't even connect it to a completely dead car battery to even give it a little charge. If this jump starter had a "boost" mode like many of the portable lithium ion jump starters, it could be the perfect product. I ended up returning the item for this reason. Read more

I was skeptical at first, but this adapter works flawlessly. I used it compatible with my battery to jump-start my SUV after it sat for two weeks. The process was intuitive: connect, clamp, and ignite. The cables are heat-resistant and flexible, making them easy to position. The safety features are well-implemented—steady red light for wrong polarity, blinking red for low voltage. It’s not for deep charging, but it delivers a powerful burst to start your engine. Perfect for roadside emergencies. Read more

I've bought half a dozen little jump start kits over the year but I always forget to keep them charged and the batteries eventually crap out. I saw this and thought it would be perfect, since my Makita batteries are always charged up and I only need this at home to jump the lawnmower when it dies. The construction of unit feels sturdy and well made. It's easily carried/stored and it's especially nice that the cables disconnect so you don't have to worry about wrapping them up (they're pretty thick). My Makita battery fit in perfectly and the lights on the unit work as they should. The instructions tell you to connect it to the car battery and let it sit for a bit to give it a pre-charge, then crank the engine. I did this on a dead zero turn and it started right up. I expect small cars would work just as well, though I didn't have a dead car to test it with. I'm skeptical on how well it would work to jump my Ram (those little jump start kits have had problems as well) and hopeful I'll never have to test it. YMMV. If you're a landscaper or handyman who uses Makita tools (and why wouldn't you?), this is a tool that should definitely be in your truck! Definitely recommended. Read more

This is the most practical car accessory I’ve bought in years. I travel frequently for work, and having this jump starter adapter with my battery means I’m never stranded. The compact design stores easily, and the detachable cables are cleverly engineered. I’ve used it in rain and cold, and it performed without issues. The conductivity is impressive—it started my car faster than some dedicated jump packs. Remember to wait 5 minutes if it fails the first time. Highly recommended for reliability and convenience.
