It’s worked every time I needed it. Very reliable, charges fast, and it’s very easy to use that’s idiot proof

This a great item and has paid for itself already. I bought my first one, (yes, I now own 2. One for each vehicle) before a trip where I was leaving my vehicle in a long term parking facility while traveling by air. I was concerned that the vehicle camera would drain the battery even though it’s programmed to prevent this. Call it a backup plan. Well, we did not need it. We did drop our other vehicle off to be serviced while we were gone and arrived to a dead battery due to lights left on. Use this to jump the car and fired right up from a battery that would only make the starter click. After the jump the capacity on the Hulkman only dropped to 97% so this has plenty of jumps before a charge is needed. I bought the fast charger for home and a carry case to keep the hulkman and its accessories together in same unit. I call it cheap security. Not to mention since it has usb c port, makes a handy charger for phones etc when you’re far from power or it goes out. Built like a tank and well made, the first time you use it to save yourself from being stranded, you’ll be thankful you bought this. I looked at a lot of other models but I settled on this one for the build quality, the reviews and functionality. It’s a good one. No issues even starting my 5.0L V8 F150. It just did not care and easily started it. Like I said, it’s already paid for itself and why I bought one for our other vehicle. You’ll be happy with this one.

I Used this this to jump start a completely dead battery on my mom’s 2001 Nissan Altima. She rarely uses her car nowadays. Since the last oil change of her car in January of this year until October of this year, she drove a total of only 48 miles! The battery is less than a year old, but due to the lack of turning on the engine for weeks or months at a time, the battery completely drained to the point where the key remote did not open the doors, the car alarm did not sound when manually opening the door with the car key, nor were the headlights or interior lights working and when attempting to turn on the ignition, there was not even a clicking sound. After reading the ratings and reviews, I decided to purchase the Hulkman Alpha 85 jump starter. I am extremely glad I did. I received it today, read the simple instructions, charged the jump starter using the included usb cable. Th Hulkman was ready to be used in about 5 minutes after charging it. When I connected the included jumper cables from the Hulkman to the car battery terminals, the screen on the Hulkman displayed error code 2, meaning the battery is completely dead. This required the use of a forced charge from the Hulkman. This is performed by pressing the on/off button and the LED control button simultaneously. This initiates a very quick charge into the battery. Immediately after initiating the forced charge, a split second later, the car alarm system sounded, indicating a charge into the battery. Immediately afterward, I turned on the ignition and the car came back to life! I disconnected the Hulkman from the battery and let the car run a while and drove it for about an hour to charge the battery. I started the car 6 hours later to test out the battery and it still works. The Hulkman Alpha 85 truly works great. Simple to use, quick to charge and quickly jumps your car battery even when completely dead. Feels durable even though it is compact. I highly recommend this as a must have tool for your automotive needs. It

Outstanding jump starter. Easily starts large engines (up to 8.5L gas / 6.0L diesel), even with a completely dead battery thanks to BOOST mode. Bright display shows exact battery %, voltage check, 10 safety protections (reverse polarity, short circuit, etc.). Very compact, premium matte finish, powerful 400-lumen flashlight, and doubles as a solid 20,000 mAh power bank. Best value in its class. 100% recommended – stays in my car permanently.

Works great, easy to use. However, charge decreased from 97% to 88% after an easy jump start of a 3L gas engine, so "up to 60 jump starts" appears to be a very big stretch unless you're starting a really tiny lawnmower engine.

I bought this awhile back after having to call roadside assistance to charge my battery earlier this year. When I got it, I put it in my car and didn't give it much thought until today. I had hoped to came fully charged but I wasn't really sure until today. Thankfully it did come pre-charged and it had 76% when I went to use it. After reading the very thorough instructions, including the error message information which I did need, it was easy peasy and my battery was charged right up. I made it to my appointment in time and I was exceptionally pleased. Great value, totally helpful, and I avoided sitting hours waiting for roadside assistance to do the same thing that I just did with this product. Fabulous!
