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. ✌🏽

I have a Wolfbox rear view mirror/dash cam on my Tacoma and love the product. Good to have a battery jumper in your car for emergencies so I decided to try this product. It looks good and gets the job done. I do some mountain biking also so it's good that this thing can pump the tires up to the PSI I need.

This product works so well, instantly as I hooked it up to my Acura rdx that was sitting for a while turned right on. Battery life is great, quality build, and was easy to charge just used my iphone block.

This jump start box is everything we needed! Easy to use, portable, sturdy and well made. The battery seems to hold for a long time once charged and jump started quickly.

Very Impressed! Fast shipping with Prime to boot. Very well packaged, and great instructions, many companies lack in that area. Upon arrival had 1 bar of charge. Put on charger 1st thing, did take a good 6 hours to get to 100% (So beware). They do provide USB C cable, however no charge block, which I found odd, for a item of this price point, reason for 4 star, and not the 5. I will be using this in my Camaro (Small Trunk), and when / if needed on Ford Explorer. Tried / Tested Air and Boost mode, and work without any issues! Neighbor is a mobile mechanic, and recommended this item, and glad he did!

The WOLFBOX 3000A Jump Starter with built-in air compressor has saved me more times than I can count. It jump-starts my SUV effortlessly, even in freezing weather, and the 3000A peak power is no joke—it kicks the engine to life instantly. The built-in air compressor is fast, accurate, and easy to use, perfect for topping off tires or dealing with a slow leak on the go. The digital pressure gauge is spot-on, and I love that it shuts off automatically once the target PSI is reached.The flashlight is super bright and has multiple modes, which came in handy during a power outage and a roadside emergency at night. The unit feels sturdy, the battery holds charge for weeks, and USB-C fast charging makes recharging quick and easy. It even charges phones and laptops in a pinch. This thing is compact, powerful, and incredibly versatile—I honestly think every car should have one in the trunk.

bought 3 of these types of units from Amazon to give them a test.This one seems to be best for trucks or heavier use.Small cheaper unit was $50.The Acezuk was $60 and thewolf box was $95.Comparing it to the others:Battery capacity is likely largest although AceZuk states more capacity for $30 less.The small unit says it is 74wh, Ace states 81wh, Wolf states 59.2wh ( I’m not trusting these numbers )Small unit weighs 475g vs 1035g(Ace) vs 1500g(Wolf).It has the thickest jumper wire and seems to be well thought out. It has a boost battery mode the others don’t have.All the ports and outlets are labeled.The unit has pads on the bottom to dampen the vibration. So when you’re inflating something it shouldnt be jumping/ chattering on a hard surface.The unit has the biggest and brightest safety light of the 3.You can switch to PSI, bar, kg/cm, and kpa.Buttons feel good and the unit is big and heavy.Overall it seems to be in line with what you pay for. Probably good for someone with a truck or someone who has to jump more than one time between charges.

My van quit working and it seemed like it was the battery. I looked on Amazon and found this Wolfbox charger and thought I would give it a try so I bought it. It was delivered the next day and I attached it to my battery and immediately my van started up. I am so glad I bought this item because now I have peace of mind traveling knowing I can start my van if it happens again. So worth the money it’s fast, compact and has a nice case it comes in. Love it!
