Good to have.
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.

Great, well made product! Highly recommend!
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!

Awesome jump starter
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.

Compact yet powerful.
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

Great product and service
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.

Easily one of the best.
I've been using this for a little less than a year. I've used it several times as a jump starter and a lot as a battery bank. It's easily one of the best-built jump starter packs out there are justifies its price. The case is solid, the cables are high quality and it delivers on its promises. Here are a few of the ways I've used it. Jump starter: A 500 CC ATV (a lot) Several car engines from 2.0 to 4.7 liters. A 6.2-liter boat. 12V output: The DC output will handle some pretty meaty loads. I tested it with my ARB fridge and it handles it just fine, but only for about an hour. 90 Watt 12v to USB-C Charger. lots and lots of little projects like fans, and microcontrollers. USB: Phones tablets chromebooks MacBook Other Batteries (Anker Powerhouse II) NOTE: This model maxes out at 18 Watts output for USB-C but it will still put that amount of power into most USB-C computers like my MacBook and chromebook. It extends the runtime of my computer significantly, though it will still discharge the computer in use. Things I like: It's actually the thing people want from one of these devices - a reliable and durable jump starter and battery pack. Mine has seen real use and its still 100% minus cosmetic blemishes. Honestly this should be the minimum standard for this type of device, but I've had a few and this is the first one that actually meets the bar. I like that it has USB-C in/out. I can charge it with and charger I have and it supplies most of my usb needs. The speed charger is FAST. 60+ watts get's it fully charged in about an hour. Things I don't like: No case. Just a little crappy case or bag would be nice. The % display is inaccurate. It doesn't load compensate so you can go from 100% to 94% in a few seconds of putting on a load, and when you remove the load it will go back to 100%. I'm not sure I'm getting all the rated watt/hr. Seems a little light in my testing, but it's close. It's certainly enough for what it is. The fast charger is a special standard (16.8V/3.8A) and not a USB-c standard like PD so it ONLY fast charges on AC no matter what high-powered USB-C input you use. My USB tester doesn't even recognize the signal and it won't pass it on so I can't test it in speed mode. Honestly, if the input was USB-C PD at a full 60 watts in/out and came with a case this unit would be damn near perfect.

This is the brand you want. I chose the Alpha 85 which will start all GAS cars and V8 Gas trucks.
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.

An Amazing Piece of Kit - Excellent Purchase
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.

Che dire ..... tra tutti i vari avviatori starter auto credo prodotto al TOP !!!
Prodotto incredibile ottima fattura , plastiche e solidita' e robustezza .... non credevo ! Devo testarlo (spero di no ! ) ma dai vari video su youtube e dai vari commenti qui su amazon pare sia davvero uno dei pochi che funziona davvero e avvia un auto , anche SENZA la batteria , pazzesco ! Praticamente sono 4 batterie al LITIO da ben 5.000 A per appunto un totale come dichiarato dal produttore di ben 2.000 A ! ACCESSORI in dotazione anche quelli al TOP , 2 robusti cavi con coccodrilli , suo alimentatore caricatore e addirittura una femmina a 12V per caricare o usarlo per i vari accessori a 12 volt usabili sull'auto , fico ! Puo caricare uno smartphone ... quindi fa anche da Powerbank . Torcia a LED classica con varie possibilita' fissa varie luminosita' , lampeggiante , strobo e pure ROSSO lampeggiante , bello ! Che dire designer e progetto Americano ma Made in Cina , ma ripeto prodotto al top . PRO : - Solido e valido dovrebbe consentireben 3 avviamenti . - Torcia a Led con varie opzioni - Carica smartphone (powerbank) - uscita 12V per accessori in auto (comodo) CONTRO : - cavi un po' corti (ma forse meglio cosi per la caduta di tensione ! ) - GRAVE visto il costo .... manca una sua custodia in vendita a oltre 35 auro !!!! che dire stra' contento e .... SUPER CONSIGLIATO !
