I have 2 cars and don't drive much so a couple times a year I can find myself with a dead battery. The insurance company was getting annoyed about my regular use of roadside assistance. Purchased this and can confirm, it works like a charm.
Good test; I’m thinking of getting one of these as a 2nd starter. I have a Tacklife jump starter which looks almost identical but has less capacity. Even so I’ve used it several times on my Mazda when it has not been driven in a long time. I’ve also used it on my VW when it wouldn’t turn over in -4 deg F. I also used it during a multi-day late-summer power outage to charge my phone, LED lights, and even a small USB fan to try to keep comfortable. These usually aren’t useful for a completely dead battery. I suspect maybe it wasn’t completely dead but still very much discharged. (Wish we’d seen a voltage test across the battery terminals before using the starter.) But the fact that it worked is very good. Usually it’s only useful if the starter only “clicks” but doesn’t turn over the engine. I like the boost button feature on this; that seems to be what finally provided enough juice to start. Mine has that and it sometimes means the difference. Also these have a timeout feature; from the time you connect the clamps and press the boost button, you gotta get back in and try to start within maybe 30 seconds at most. (As you were making a video and describing the process I’m yelling “Get back in the car! 😅) Little tip: turn the key to “on” and let it run for a few seconds before cranking. This primes the fuel pump. I think that’s why it started and died on the 2nd attempt, because there wasn’t enough fuel at the injectors. But 3rd time’s a charm. 🎉

Bro roadside assistance for a simple jump start is craaazy 😭
Cool. I have same jump starter. Thanks for your video instructions. 👍

Wow really good too about the fuel injectors
The Rav4 negative battery terminal clamp is loose. You can see the clamp move when you attach the jump starter.
Thanks bud for your video
