Hulkman Alpha85 Smart Portable Jump Starter, 2000A Battery Booster Pack with LED Display, Flashlight, 74Wh Power Bank & Jumper Cable, 12V Jump Box for up to 8.5L Gas & 6.0L Diesel, Cars, SUVs & Trucks

This thing is awesome! I was having trouble in the winter with my car battery not having enough juice to start my car if I let it sit for more than 5 days. So I bought one of those $45 lead-acid battery jump starters that also has a built-in air compressor. Let's compare that jump starter's performance to the Hulkman's. First of all, the $45 jump starter is the size of 2 big lunch boxes and weighs over 10lbs. After charging up the $45 jump starter for a few hours, I could get maybe 5 jumps of a weak battery out of it before it would need to be recharged. Then, if I left it unplugged in my house for a week, it wouldn't have enough juice left to get a single jump out of it. So I started leaving it plugged in all the time to ensure that if I ever needed it, it would be charged and ready to use. If I needed to use the $45 jump starter in the morning before going to work, when I got to work, I would take it inside and plug it in to make sure that when I left later that day I'd have enough juice to jump start my car if necessary. This whole arrangement was not convenient to say the least. Then, I read about these new lithium ion battery jump starters like the Hulkman. I decided to pay the bucks to get one and try it, and it was worth it. The Hulkman is about the size of box of legal envelopes, and weighs less than 4lbs. In December, I charged up the Hulkman in less than an hour (it came partially charged). At that time, my battery was completely dead, so a single jump depleted about 10% of my juice as indicated by the charge indicator on the Hulkman which read 90%. The car cut off once after the 1st jump, so I had to do it again. I estimate the Hulkman could jump start a completely dead battery like mine (small 4 cylinder Japanese car) maybe 6 times before running out of juice. Using it regularly over the next 3 or 4 weeks to jump a weak, not completely dead battery, barely any juice would be depleted for each jump. The display told me I still had 98% charge after the first jump. I had no fear that I wouldn't have enough juice when I needed it. Then, I fully charged it to 100% and left it in my car outside in my driveway throughout the whole winter from January to May before using it again. I live in Hampton Roads, Virginia, so the winters aren't severe, but we did have plenty of sub-freezing days during that period. After all that time, it was still at 100% charge. I used it to jump a very weak battery - not completely dead, but very depleted - and it said I had 90% charge left. That's after sitting OUTSIDE ALL WINTER LONG FOR MONTHS!!! I had to jump it again because, as usual, the car cut off after the 1st jump. Now I had 84% juice. When I got to work, I took it inside, and it recharged to 100% in LESS THAN 30 MINUTES while I was talking to my boss and a coworker about how awesome it is. Moral of the Story: For God's sake, just pay the extra bucks an get yourself a jump starter that is reliable, convenient, and that will give you peace-of-mind. I wish I hadn't wasted my money on the $45 piece of junk.

Really happy with this jump starter! It feels well made, is compact enough to keep in the car, and is very easy to use. The display is clear, the built-in flashlight is a nice bonus, and it has plenty of power when you need it. I also like that I don’t have to rely on another vehicle to get a jump. Definitely a great item to keep in the car for emergencies and gives me extra peace of mind. Highly recommend!

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 have had this for almost FIVE years now! This is an amazing product!! Buy with confidence!! I previously had a cheaper ($60) battery pack and not only was it not strong enough to jump start my motorcycle, I ended up swelling and non-functional after only 1 year! After that I did a lot of research and decided on this unit and I am SO GLAD I did! This thing will jump start a full size SUV and only drop to 5% It will charge 2 cell phones 3 times (6 full charges) on a camping trip and still have 35% left! I think it may have lost about 5% of it's strength after 5 years but it's still going strong! I liked this brand so much, I bought a battery tender/refurbisher for my motorcycle and I swear it has extended the life of that battery by keeping it connected in the winter. THIS THING JUST PLAIN WORKS! I am gushing over it simply because so many other products out there disappoint. THANK YOU HULKMAN... I'm your customer for life!

I purchased this JSPB back in 2022'. Its worked flawlessly ever since. I recent had my car battery go dead after 5 years but my new battery was not arriving for a week. Fortunately, the alternator was still good. So all I had to do it jump it, which I did with the Alpha85 for a week. My SUV has a 6.2L V8 and this would jump start it with no problems. Simply hook it up, watch for the "Ready" note and simply crank it. I will say the battery became so depleted that the #2 errpr would light up which mean the voltage was too low to regiester. In that instance, I simply held the power and flashlight to enter force power mode and again it would light "Ready" and fired right. Great device to have. No bulky jumper cables needed, no having to flag down a stranger for help for a jump, no AAA neeeded, NO WAITING!. Quick and abolutely convenient!

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 device far exceeded my expectations. It even exceeded my hopes. I plugged it in and charged it up when I got it. Then the first time I used it to jump start a car it went from 100% to 97%. I thought "at this rate it should handle 30 to 40 starts, so the display must be wrong." After using it for 22 starts it says 48%, so it's real !! It's mind blowing. it really has me wondering about car batteries now. If your cars sit for long periods and you can't trickle charge them, this is a super easy way to get them running. I honestly was expect about 5 jumps on a charge, not 42. The clamps are fine, the disconnect is fine, the display is fine. USB charging is great. Hulkman, thank you for a fine product.

I have bought different versions of this device from different brands and many of them I found to be unintuitive and difficult to use. This one, on the contrary, is very easy to use, and very effective as well. I have used it twice, already to help jumpstart cars of a couple of friends, and he did not let me down either time. The size is comparable to other battery jump starters so I keep it under my front seat where it doesn’t bother me. I believe it’s a good value for the money.

Trés bon produit, j'en avais déjà acheté un il y a plusieurs années et il fonctionne toujours aussi bien, on peut le laisser dans le coffre de voiture durant des mois, même en hiver, la batterie est toujours pleine quand on en a besoin. J'ai donc commandé celui-ci pour mon père qui en cherchait un qui fonctionne vraiment. Je recommande!

Ho acquistato questo avviatore di emergenza dopo aver avuto alcuni problemi con la batteria dell’auto e devo dire che si è rivelato un prodotto estremamente valido e affidabile. Fin dal primo utilizzo trasmette una sensazione di qualità costruttiva, con materiali solidi e una buona cura dei dettagli. Le dimensioni compatte lo rendono facile da tenere in auto senza occupare troppo spazio, ma allo stesso tempo la potenza disponibile è sorprendente e più che sufficiente per avviare il motore in pochi secondi anche con batteria completamente scarica. L’utilizzo è semplice e intuitivo, grazie al display ben leggibile che fornisce informazioni chiare sullo stato di carica e sul funzionamento generale, evitando qualsiasi incertezza durante l’uso. Ho apprezzato molto anche la presenza delle protezioni di sicurezza, che fanno sentire tranquilli anche chi non è particolarmente esperto, riducendo il rischio di errori o danni. Oltre alla funzione principale di avviamento, si dimostra estremamente utile come power bank per ricaricare smartphone e altri dispositivi, soprattutto durante viaggi lunghi o situazioni di emergenza, con una velocità di ricarica davvero soddisfacente. I cavi risultano robusti e ben isolati, dando un’ulteriore impressione di affidabilità nel tempo. Nel complesso è un acquisto che consiglio vivamente a chi cerca una soluzione pratica, potente e versatile per affrontare imprevisti con l’auto, offrendo un ottimo rapporto tra prestazioni e utilità quotidiana.

To be honest I don’t know if it’s 1 or stars at this point. What I can say is that despite reading reviews and comparing products I did not get what I wanted. The reviews that talk about starting a vehicle with a completely dead battery are misleading unless you purchase /have the boost Option. In clear terms. If the battery does not have any (the tiniest) voltage flow measurable by the device, it does not detect and or switches to „ready“ which actually gives you the current. You can buy a different cable that has a boost function on button press (I assume it simulates minimal flow“ that gets the product to ready. Feel free to comment if you feel I have a defective device in general or just got it wrong. Didn’t work on my 911 where I need a current through the fusebox just to open to the hood to get to the battery (MGM battery) Didn’t work with my Spitfire with a completely dead battery Didn’t move to ready with my Audi with a new MGM battery because apparently it would switch to ready if the battery is healthy / has a healtybvoltage / current either. 🤪 A 7m jumper cable would have probably been cheaper and would work. Not sure if I go for the boost cable option. Found 3rd party only so far.
