3000A Jump Starter with Air Compressor, 59.2Wh&160PSI Portable Car Battery Jump Starter with 65W Fast Charge, 12V Battery Pack (8L Gas 6L Diesel Engine) with Boost, Light and Jumper Cables

Jumps my Diesel no problem, Air compressor is surprisingly fast for a small unit. The included case is really well made and stores easily. These are lifesavers to just keep in your car and I highly recommend

A quick summary is that this little unit holds a lot of power/features and is much better than my older lead-acid style jump starter/inflator device. I purchased this Wolfbox portable jump starter/air compressor to replace and older unit I previously kept in my vehicle. Although the old unit does still work, it is massive/bulky, taking up a lot of floor space in the back seat (it is the big yellow CAT unit in the photos/videos). And what a difference it is, sitting at less than half the size even in the carrying case. Apparently the Lithium-ion batteries in the Wolfbox are the way to go these days compared to the AGM lead-acid battery in my old unit. The Wolfbox unit comes with the jump starter/inflator, jumper cables, inflator hose, a few valve attachments, and a USB-C charging cable all packed within a nice carrying case. (and also a manual). Great presentation overall, and it feels sturdy/premium. The only note I can think of for Wolfbox to improve here would be to add a piece of foam in the center of the case to act as a divider/protection. This would keep the jumper cables/other contents stored in the pouch from touching/scratching the jump starter unit stored in the other half. Not a huge issue by any means, and I rectified this by cutting out my own piece of thin foam (you can see it in the pics). It looks so nice I would hate to see it scratched up over time. I charged it as-directed out-of-the-box, and it took less than 30 minutes to top it off. Reading in the manual, it says it would take 1.5-2hrs time for a full charge. My old unit recommended charging for 24 hours, so a big improvement there as well. Given this time of year, the cold temperatures have come in and caused all of my tires to lose some air pressure, setting off the dashboard warnings. So I thought this would be a perfect opportunity to compare the air compressor feature vs my old one since all tires needed to be filled 6-8psi. The short story is that the Wolfbox wins out again. I had two tires that both showed they were 6psi low exactly, so I set my old unit on one tire and the Wolfbox unit on the other. My old unit took 3:51 (3 minutes and 51 seconds) to inflate 6psi, while the Wolfbox took all of 1:13 to inflate 6psi. So the Wolfbox is 3x faster than my old unit. Quite impressive for being half the size. I love how big the display is. The screen is bright and I can easily read the numbers while standing up compared to the tiny screen on my old unit. It also has cool functionality that lets you set the target PSI, and it will auto-shutoff when complete. There are presets for a vehicle, motorcycle, bicycle, and ball, but you can set it higher/lower than those and also update the preset if you want. While I have not been able to test the jump starter functionality yet, it advertises 3000A compared to the 1200A of my old unit. I'm unsure how that translates to actual cranking amps, but seems to be more than capable for my medium size SUV. Overall, I am quite impressed at the power/functions/features. Coming off of my old unit, it seems to be an improvement in almost every way. The price is reasonable for what you get. Hopefully I won't have a dead battery and have to test the jump starter, but good to know it's there.

While getting prepared for the upcoming snow storm, I found my diesel generator was COMPLETELY dead. I had been thinking about a jumper box for a while now, even more so now that my son drives daily to college. This one being well reviewed, with a solid/ flashing light and built in air compressor caught my eye. It was delivered this morning, and I charged it fully as recommended. I was also unsure of is power because this small thing is a lot smaller than the old heavy type jumper box I'm used to. When I tell you I was very pleasantly surprised when this generator jumped to life immediately!! I bought one for my car and one for my sons car. I will probably add a third for the wife's car. Since I will have it in the other 2 cars, that almost guarantees that it would be the vehicle without the jumper to need it! I do wish the cables were a little longer. That shouldn't be a problem in a vehicle, but a little awkward on the generator. I contacted the company about something and they were SUPER responsive. It's only day one and I jumped the generator 2x already, looks like I'll probably need to replace the battery on that. Im pleased to know that is I need the generator before I replace that battery that I can get it started. So far so great and my initial impression is to recommend. Will update if necessary, positive or negative.

So far so good ! I've only had it a month and use it to fill air in tires a couple times. It has held the charge in its case in my car in cold Michigan winters, though I try to remember to bring it in out of the cold. I haven't had to use the jumping feature yet but everything looks good, it's user-friendly and nice and compact with a sturdy carrying case that sits nicely under a seat.

I've only had it a few days, and haven't used the jump yet, but AAA had to jump one of my cars from a battery not putting out anything, and it jumped it immediately as if I had put a brand new battery in. What I have used is the air pump. I topped off all 4 of my truck tires with 10 pounds each to 60 psi, 8 more tires @ 3-5 pound top offs on 2 SUVs, and my boat trailer 4 tires plus spare from current 70 psi to 90 psi. It was impressively fast for such a small package on the cars, and decent on the boat tires (tractor trailer size tires), but it took the entire battery down to 1 blinking bar that was close to running out. No slow down in pumping and it did the entire job, so I'm sold and will be buying 2 more once I see the longevity of these. I hope it holds up because I really like this unit, just wish it had a cig lighter plug in. I'll add the 5 star if it holds up.

I bought the WOLFBOX 4000A Jump Starter because I was tired of being at the mercy of dead batteries and slow, bulky compressors. This thing earns its spot in the car. The jump starter is strong enough to fire up a truck without hesitation, and the air compressor doesn’t struggle the way the cheap ones do. Tires, bike wheels, sports gear—it handles all of it. The 65W fast charge is just a bonus, but it’s one you end up using more than you expect. What I like most is that it’s built like something you can depend on. The screen is clear, the attachments aren’t flimsy, and it packs down small enough to keep in the Jeep without eating up space. I’ve already used it twice helping other people who weren’t prepared. And here’s the thing: this is one of those Christmas gifts people need, not just something that gets opened and forgotten. Adults, teenagers with their first car, even college kids who drive home on weekends—everyone should have one of these in their trunk. It’s practical, it’s useful, and it’s the kind of gift that actually solves a problem before it happens. If you’re building a list of “smart gifts” this year, put this right at the top.

Where has this been all my life? I bought this when I was stuck in traffic behind a vehicle whose battery died. I got out to assist and another driver jumped out with one of these. Started their car right up, no clunky jumper cables, no maneuvering cars in different, awkward positions. Just attach and go. Also no more trying to hunt down free, broken down air stations that charge $2.50 plus tax for a low tire. I wrote the name of this down, came home and placed an order. Not too heavy, easy to store (comes with a case), and easy to use!!

Great battery jumpstart device! Comes with a beautiful case that holds the main unit and supplied accessories. It is so easy to use! I filled my bicycle tires easily after topping off the charge and charged my drone battery, too. I can either charge it from my laptop, or with a USB wall voltage converter (not supplied with unit).
