Customer Reviews
I haven’t tested it on the car yet, but I like it so far. The built quality is top-notch. I’m confident that when that day comes that I need to use it, it won’t let me down. Also, now I have a power bank for my laptop and phone!
Had an Alpha 100 shipped to my Buddy in NY, Well worth the hassle, I am so pleased with it. Canadian winters will not seem as daunting from now on.
Got caught out last year at minus twenty, bring it on Jack Frost.
This is an amazing product! I have a ‘92 F250 7.5L with a completely dead battery, I jump started it with Hulkman 10.0 and had it running in no time . This product is the best in the market worth every penny .
I bought a box store special jump box and it literally did nothing for my Harley or my diesel manlift. I had to put jumper cables on my truck and wait 30 minutes to start the lift. This little thing started it after sitting for 3 months, in the cold, INSTANTLY! What? Get one!
I haven’t had a chance to use my 4000A yet, but I have it in my truck and ready to go.
The unit, cables and case have a high quality feel and I love the high viz read out.
Simply unbelievable:
Had a question about the item and customer service person was rude. Will not recomend.
I have used this a few times already. It is great!

“I bought this little device for the cold Kansas winters, and it has already saved me from a dead battery a couple of times. I even used it to jump‑start a stranger’s vehicle, so it definitely works when you need it.It charges quickly, especially with the included AC charger, and mine arrived already at 74% power. I really like its compact size, and the price $99 was great. The unit doubles as a power bank with both USB‑A and USB‑C ports, which is a nice bonus.Overall, this is a great unit. It would be absolutely perfect if it had a built‑in tire inflator, but even without that, it’s been a reliable and handy tool to have.”

“I already have the Hulkman 85, and it is a very reliable device.I bought my adult daughter one for her car because her 3-y.o. likes to play with her car's lights.The new Hulkman is considerably less expensive than the one I bought for myself 3-years ago. One way they were able to sell it for less was by not including a fast charging unit (65-watt capacity) for the model 85. I discovered that the fast charger could recharge my unit in about an hour. However, the standard charger can take half a day to fully recharge the unit. Unfortunately, nobody sells this fast charger and even Hulkman has trouble keeping them in stock.I wrote to Hulkman and told them about this situation.I was very pleasantly surprised that Hulkman sent me a free fast charger for my daughter's car.Not only do they make a great product, they also have awesome customer service.”

"I've had my battery starter for about 2 years and never had to really use it. I think I've used it to charge my phone a couple times. I charged it up initially when I got it and it has held 96% for that whole 2 years without charging it again. It just happened the battery in my car was dead today. I took it out to the car hooked it up and the car fired right up. I was very skeptical that it would jump start my car but it sure did. So easy to use. So convenient. I think it just gives one piece of mind to know that if you got this in your car and your battery goes dead you're good to go. I'm so pleased with it that I ordered another one today so I would have one for each vehicle. They are all so great in the event you have a power outage. You can get one of these cheaper but I know this one works."

"This thing is worth every penny! I just had to use it last night. Easy to set up and had my car started in no time. My battery was really dead so I had to use the force start feature. I also used the flashlight that is on the unit and it worked great. After starting the car with the force start, the unit still has a 95% charge. Ready to go for next time. Great product! I am buying one for all of our vehicles and for family!"

"Wow. This thing is amazing. It arrived with a 67% charge and I immediately tried it on my 1.9 diesel Zafira which was completely and utterly dead. Didn't even have enough power to manage the central locking. I switched my Hulkman on, connected the jumpers and turned the key. It started immediately. The charge on the Hulkman fell to 64%. Amazing. I've now charged it up to 100% via its USB-C and it took about 40 minutes. Definitely recommend. Wish I'd bought one sooner."
