I’m watching for a deal on NOCO Boost jump starter for vehicles and boat.
I own this one from Gooloo, and highly recommend it. Well worth the price, and is $20 off right now (check the box just below the price in the description). The difference is that this Gooloo model has a pre-heat setting so that it works just as well in below zero temps, and we know that cold temps is when you are most likely to need a boost in your car. Can be used as a power bank also, it has three USB ports, including one that is 15V/10A for powering more robust tools and such. Also has a built in 400 lumen flashlight and the digital readout is fantastic.
Posting links is sketchy here at best, so just search Amazon for this item:
