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

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.

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.

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

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.

Seems like a good charger looking at YouTube reviews and saying how fast to charge it up . One hour with 65w charger. It doesn't come with a 65w charger in UK and it doesn't work with other 65w chargers has to be their own one which isn't available in the UK. With normal charger apparently takes 4.5 - 5 hours to charge bit different to one hour. I will stick with my noco charger .
