WOLFBOX 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

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.

Used this more often then I'd like to but it works everytime even in cold weather the tires fill up fine and jumps the battery fine

So far so good. Bought this baddie to figure out where a parasitic drain was coming from, ive had it for about two weeks. It has a battery tester, which was a pleasant surprise since i just had a hunch that the car battery was not bad. so ive used it for the jump at very least 3x a day (it gets embarrassing to do on a new car trust me) but id have to jump the car every time I started it until i was able to fully charge the 12v via driving+alternator. I only charged the car battery with this box for about 45 maximum max but I also did not check my battery to see where it was at before hand witha voltmeter because i knew it was completely drained. The wolfbox effectively repowered the entire car, all accessories ect after 45 minutes. I still had more than half the power left in the wolfbox, even after using the boost button a few times. Only charged the wolfbox when i bought it, and once more at the end of the week after jumping my car approximately 9x. I fully charged it again, carried me another week and only used half its power once again. its so small, easy to use and the manual is small but easy to understand with spanish and english directions. The 2 things i can shamelessly complain about are: length of cable lines (i have to rest the box by wiper blades when id like to be seated in my driverseat looking at stats) and the thickness of the clamps themselves... i have a hard time clamping the ground port (black) on my (car) battery because that part of the port is slightly under the lip of the dash, and the other is close against the battery box. Ill take a photo when i get some daylight or a video if its too difficult to make out via photo. Overall, saved me from having to buy another battery (230$) and murdering that one too- (i didnt know the drain was parasitic right away) the time and dignity of being able to diagnose and fix my own issue without the hassle of anyone else trying to blow smoke up my tailpipe (priceless, truly) also caught this baddie on sale. Kind of excited for the weather to change so i can add some air to my tires and not have to wait in a free air line 🙃 but I digress. Measure the clearance you have to clamp the ports and make sure you have (car) battery access first, note: before I bought this box, i asked someone with a 2025 explorer to give me a jump; his battery was within two compartments and the second was under the dash...there was absolutely no clamping access. Just a heads up for newer car people who are dealing with battery beef and are trying to avoid the dealership. ✌🏽

This is a life savor and a most have I’ve got this before going out on a road trip on the first drive one of out family members cars battery died and the whole trip was about to go south luckily, I reminded myself that I have this in my car. 15 minutes later we were all on the way. Thanks, God. For this small and compact feature packed air inflator. / battery starter. It’s powerful. And extremely easy to use and as a bonus it comes with a durable case.

This item works well to jump start a large vehicle or to pump tires. Leaving off one star because it has such a large, easy to read screen, yet it is all only used for the compressor. It would be nice if the screen gave information when using this as a booster, i.e., percentage of battery left, car battery voltage, jumper connection status, etc. Instead, there are two tiny lights on the cable plug that you need to check against a legend to see if everything is connected properly and ready to boost. Wolfbox makes tough, durable products, and this one is no exception,. I just wish they would’ve taken advantage of that awesome display screen to make this much better than all of the other combination booster/compressor units out there.

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.

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!!

Outstanding.... Battery and starting is off the charts good. Battery in my 4.0L Jeep had a cell die. I used this 4 times to start it over an hour and still had 80%+ battery life.... Disconnected battery on my 5.3L V8 and fired right up. Pump works well, just be patient. Plus I tested it on 35x12.50R16 so even my shop compressors, take time to affect pressure.. Lol. If Wolfbox reads these... 6 more inches would be great on jumper leads. It's not that it doesn't work and the lengths aren't different from other brands, but that 6" would sure be nice to make me feel better about securing it...
