HULKMAN Alpha85 Smart Jump Starter 2000 Amp 20000mAh Car Starter for up to 8.5L Gas and 6L Diesel Engines with Boost Function for Totally Dead Battery 12V Lithium Portable Car Battery Booster Pack

Had this over a year now, I have used it a lot, without ever an issue. It frequently is used to jump a 40 year old Landcruiser 2.5L Diesel in Balkan winters down to -25c - With dual 12v batteries and has no issues, drops to maybe 85% if it's really struggling on a cold day. We just had a battery issue with a VW Golf and it required jumping every start, this has been jumping endlessly and rarely even with 5 jumps goes below 75% on the 1.6L VW. It always sits in these vehicles, outside, in those minus temps, over night and that doesn't seem to bother it. It feels of great quality and I'd highly recommend. If I had one qualm, it should have come with a carry case.

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.

Very handy tool that can save your time and money in need. Love it.

Used on a few different cars, all started fine. Some vehicles if your battery is really low, you may need to override the unit, check the instructions!

Very good

Seems very well made and by all accounts hopefully it will work as described by the very positive reviews on Amazon and elsewhere - I just wanted to express my disappointment in that there is no 65 watt fast wall charger included. The Hulkman promotional videos on Amazon and the instruction manual that comes in the box indicate a supplied 65 Watt fast wall charger - but it seems in the UK this is not the case and all we get is just the USB-A / C cable. The Amazon “small print” of “what’s in the box” does say it excludes a wall charger in the UK. I have discussed the matter with Hulkman and their reasoning is to reduce electronic waste as most people have compatible USB-C chargers. Excluding such an item allows smaller packaging, reducing electronic waste and overall more environmental responsibility - all of which are very reasonable reasons. Just be aware if you want to use a 65 watt charger than an extra £10-15 cost will need to be factored in to your purchase. I have given 4 stars rather than 5 stars as I think the marketing Hulkman promotional video is a little misleading and despite Hulkman's reasonable environmental reasoning it still seems I think that the product is sold in USA with a wall charger?!

Jumper is of a high quality. Fast charging is highly useful as well. I wanted to keep it, but I can hardly justify keeping it.

It failed after using it 3 times in 10 months.

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.

Aparato bien resuelto.. He arrancado una autocaravana que tenía la batería literalmente muerta.. (no sé encendía ni el cuadro de instrumentos) Pues conectar el arrancador y zas.. a la primera y solo consumiendo un 5% de la batería del arrancador.. prueba de fuego, superada con éxito rotundo!!

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.
