HulkmanAlpha85S,Space Gray, 2000A 74Wh Smart Jump Starter with -40℉ Start Tech, 12V Portable Car Battery Booster, 3.3" LED Display, USB-C Power Pack, Jumper Cables for up to 8.5L Gas/6.0L Diesel

I wake up at 5:45 AM and my wife is saying her car doesn't start. We've both got to get to work and it's 20 degrees outside. I go out in shorts and slides with a flashlight and a prayer. Her hood is frozen shut, we pry that open. I get out the Hulkman 85S that's been sitting in her trunk for 6 months since I bought it. Connect it up. Car starts first try.Clutch.Also important is that this is easy enough to use that she can do it by herself with no help. Big plus for us. I like that it can keep her phone going too if she gets stuck somewhere (we both have long commutes). Glad I got it! Probably will get another for my car as well.

Edit: have started multiple stranded cars with this, it is a beast. Just not my own car luckily...This product is extremely well designed and well built, everything about it just oozes quality. The fit and finish is fsntastic the functionality is great and it has fast charge in and out and 12v dc out with included car charger outlet, really great, holding it feels really solid really high quality materials and great simple design so easy to use. I love it. It's exactly what i wanted and while it was more then i really wanted to spend it has everything i wanted plus some extras and i bought the carrying case in a combo so it all came out pretty pricey about 150$ after tax but the whole deal is acceptable to me because the quality is impeccable and i want to be able to start my car in emergencies and have the added benefit of the fast charge power bank. Im a happy customer. Unless the time comes that my car bat dies and this doesn't work... lmao that would suck but i honestly feel confident in this product at this point, I've tested its charging and it's fast charge for devices i have not tested the car starting but i may do that soon

I was in the market as I had an older lead acid jumpstarter that no longer worked. I was skeptical about this one since I wasn't sure about lithium ion. However it's been great! It has enough power to jump a mid size SUV (Hyundai Santa Fe Sport 2.0) 700CCA battery multiple times. It actually saved me recently when my battery went out. I had this with me when the battery went out and was able to use it to jump the battery 3 or 4 times on a single charge. It also works well for an air pump I have. I use the power port adapter to plug in my air pump and air up my tires without having to run the vehicle and idle it while I check my tires. I use the same adapter for an air mattress air pump to inflate a queen air mattress for camping. It's backyard camping for the kids to stay in the tent but also provides a way to charge their Kindles too. The light comes in handy for all modes. Love the quick charge feature too. Handy at the beach for inflatables as well, but just as great for deflating as well. Well worth it to keep in the car with a case. Get one for every vehicle just in case.

It comes with everything you need plus more, Just NO CASE.It just doesn't make sense not having the case but it seems like they did that for the case to make a little extra which is a great sales strategy based on how strong and good this battery is. The quality of it, it seems really durable so far too.When using other modes like DC(12v cig lighter) and USB or It also lasts a lot time too. I Played 2 8" marine bluetooth speakers off it with a ton of bass for about an hour and It only went down to 79% Not too shabby given the size of those heavy bass speakers. Weird to say but I almost can't wait to try jumping with it lol. I haven't had the chance to jump anything yet but based on all the youtube reviews it seems like you can get a ton of jumps out of it. "Also tip for people that want to get this battery to last forever when you don't use it much. Even-though it is Li-ion and not LI-PO. If you don't plan on using it for a long time, store it at a 75 or 85% charge. Lith batteries don't like being full or drained in general(even for LIPO ones which actually NEED to be stored at 50% if longer than a day or 2) .This will be fine at 100% but I am saying if you maybe use it once a year, would be the best to keep it at 75% to 85%.

Worked like a charm. Battery drained due to frigid weather, topped off the charger, connected it and used override feature. Started right up. Love it!

I got this by seeing one of my friend for jump start, amazing product to keep it at home or vehicle all the time. it's performance outstanding, not only car you can carry for anything to get charge like laptop, phone, etc...check at once home before you assume. but product is sold. They could have included a good carry case, that's why 4 star.
