I purchased this a year ago for the same price and it has come in handy multiple times. I wish I had one of these back in the early 2000s. Hold a charge well and has been able to jumpstart a large battery three or four times before needing to be recharged. Highly recommended

Had a similar type charger that sat through the Phoenix summers. Lasted for around 4-5 years before it wouldn't hold the charge. Same thing with my fatmax that used an SLA battery.

The updated version is 59.49 with a %40 coupon and does not appear to be prime only, for the orange color at least.

Have a couple of these. I am surprised at how well they work. They even started some larger engines, which was even more surprising. Usually just use them for our fleet of golf cart and tractors that come up with bad batteries at the most inconvenient times. This has solved that for us. I always keep one handy and a dead battery is never a prolonged issue.

When I saw these first appearing (with li-ion batteries) in the early 2010s, I thought they were going to wind up being a very handy product to have around. However, I have resisted buying one to date because I use my battery chargers about 100x more often than I actually jump start anything, and I also have concerns about temperature extremes. I'm okay with biting at this price point and model because I have a small engine that's inconveniently troublesome. And maybe I'll throw it in the car on long trips.

But if anyone wants to point me at a model with steady 12VDC output and/or 65W USB-C PD, I'm all ears (eyes?). AstroAI wants you to step up to the S8 Ultra at $49, which doesn't trigger my impulsiveness as immediately.

Now everything is AI and everyone is talking about AI, even who doesn't have a clue about it! 😀

The amp ratings on ALL of these jump starters are complete fiction. Consider the wire gauge requirements, 20amp is a 12 gauge wire (which is about what the wire connected to these battery clamps looks like). You would need 100 12g wires (on each pole) to handle 2000a.

Now these things do work surprisingly well for what they are, but lets not fool ourselves into thinking they are going to send thousands of amps out those thin little wires.

Bought one last time these were on sale and has worked as a great replacement for a generator battery. The old tractor battery wouldn't hold a charge anymore and this started it up no problem!
