Very happy with the purchase, works as intended and is a great looking device. Review: Even better than I expected! - I have a Honda Element that I don't use much, and consequently the battery is always running low (especially if I forget to put it on the trickle charger). I've been caught a few times where it will act like it's charged and start up the first time, then after I've driven it to my destination, it won't start again when I need to drive back home. So I needed some insurance. I decided to buy this Wolfbox after seeing it tested, with very favorable results, on the Torque Test Channel. Even so, I was skeptical that such a small box could actually start a car engine, when the car's regular battery weighs like 25 lbs (small for a car battery, but still). But I tried it with a "mostly dead" battery (enough that the power locks worked but it chugged maybe 1 time when I tried to start it). It was night time so I turned on the integrated light on the Wolfbox - plenty bright enough and well positioned to see what I needed to do to hook it up. It took less than a minute to hook up, including finagling the hood open - way easier than dealing with jumper cables or the plug-in charger. The green START light lit up and I turned the key and the car started RIGHT up. I was shocked - the starter actually sounded like it had more pep than when using the regular battery to start normally. The best part is that I started with the Wolfbox at 100% charge, and after starting the car, it still read 97% full. I could drive the car around all day making multiple stops not worry about it with one charge on the Wolfbox. Also the included charger charges it super fast - it arrived about 70% charged and was charged to full in less time than my phone usually takes to charge (and it has a way bigger battery inside). Speaking of charging, I also used it to charge my phone using the bidirectional USB C port - kept my phone running at 100% using it as a hotspot for a whole afternoon, and only depleted a couple of percent of the battery. So this product gets an A+ from me. We'll see how the longevity is but it can't be worse than the regular car batteries. Which brings to mind a question - why are we still using lead car batteries when this lithium technology is clearly better AND cheaper? ## Features - 4000A&88.8Wh Jump Starter - Megavolt24 is equipped with a powerful 88.8Wh battery. this car battery jump starter is well-suited for 12V vehicles like cars, trucks, boats, and larger vehicles. wolfpack effectively restores your vehicle's power in emergency situations, supporting both gasoline and diesel engines with a capacity of under 10 liters - HD LCD Display - The LCD screen offers a transparent presentation of all the status indicators for the car jump starter portable supply.

We tried using the newer truck and a fork lift to jump it off... not even a click. I went to my truck and got my Wolfpack and hooked it up. regular jump mode made it click, so I pressed the BOOST button and it fired right on up. Shop supervisor was impressed with it so much, he had me order one for the company. It's small, compact but very strong. a must for anyone that needs a reliable jump pack for thier car or truck. ## Frequently Bought Together - WOLFBOX 4000A Jump Starter,12V Car Battery Jump Starter with 65W Quick Charger,LED Display,24000mAh Portable Jump Starter Battery Pack(10L Gas 10L Diesel Engine) with Booster,LED Light,Jumper Cables - WOLFBOX 12000mAh&150PSI Heavy Duty Tire Inflator Portable Air Compressor,Double- cylinder 58LPM Fast Air Pump for Car Tires,3.5'' LED Display,20'' Hose,Air Compressor for Car,Pickup Truck,Bike - WOLFBOX 12000mAh&150PSI Tire Inflator Portable Air Compressor, Cordless Air Pump for Car Tires with Digital Pressure Gauge, Portable Tire Pump, 1-Min Fast Inflation, Auto Shut-Off, LED Flashlight --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/613672911-wolfbox-4000a-jump-starter-12v-car-battery-jumper-starter-portable](https://www.desertcart.jp/products/613672911-wolfbox-4000a-jump-starter-12v-car-battery-jumper-starter-portable) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-06*
