Hulkman Alpha100 Space Gray,4000A 118.4Wh Smart Jump Starter with -40℉ Start Tech,12V Portable Car Battery Booster,3.3" LED Display,PD65W in&Out Power Pack,Jumper Cables for up to 10L Gas/10L Diesel

My car battery was totally dead and the Hulkman started it right fast. I love the digital display and the built in heater for really cold weather. I expect to use it on my stubborn diesel truck this winter. I tested the Hulkman battery capacity with my Atorch DL24P. The rated capacity of the Hulkman is 118wh. Mine came out a bit short at 113.5wh. Other jump starters I tested. Yaber YA60...62.3wh. JF. EGWO F60...77.4wh. Noco GBX155...93.1wh. LOKITHOR J401X...60wh. I really like the Hulkman. It has more battery capacity and like I said I love the digital screen and the built in heater. The Noco GBX155 is ok. I like the attached, longer cables on the Noco. I'm going to keep the Hulkman and give the others away.

only used once so far, easy to use, simply charge up, plug cables into battery unit, hook up to battery on vehicle and it automatically is ready to go, after 1 jump still had 95% charge left. Great unit to have peace of mind for battery backup anywhere anytime. No need to find someone to give you a jump, stores easily.

We have a 2020 Ford F350 6.7 Diesel that was having some battery / electrical issues and the Hulkman Alpha 100 proved itself to be an absolute beast! The batteries were dead enough that the remote would not unlock the doors - hooked up the Hulkman Alpha 100 and it started without any hesitation.However, the real shock came when looking at the remaining charge on the Hulkman. It was charged to 100% and after the jump there was still 94% left. The next day the battery was dead (again, the remote could not unlock the doors because the batteries were completely run down) so I pulled the Hulkman out (still at 94%), jumped it and it fired right up. The charge remaining was showing 88% - unbelievable.This was not simply a remote issue, the power running boards could not deploy when the door was opened, no interior or exterior lights, no sounds, no dashboard, no nothing - the truck was completely dead.Hulkman - way to go on a superior product!As a side note - I paid for this charger and have no affiliation with the company - the product is truly remarkable. I highly recommend.

Works wonderfully well. Was recommended by a certain mechanic on you tube ( hint, Scotty Kilmer)

Solid and a bit heavy. But, for what this item was built to do, I can understand it's weight. For someone with a small vehicle this particular item may be a bit of over kill. This company does make smaller versions for vehicles with smaller cranking needs. If you have several vehicles: small and large, then this would be the item you would want. Whether you have a small vehicle or a large oversized p/u, you can't go wrong buying this product. You would never have to worry about having enough power to start any vehicle up to 10L engines. It also works as a back up charger for your phone. So, it is a bit bulky, but you can rest assured that you'll have the power when you need(which is the most important and number one thing on any list of needs). So, Yes! 5(FIVE) big stars.

After carefully reviewing the product and getting a replacement I came to the conclusion that this product is worth having. Finally..! I was able to put it to the test it actually came thru. Bottom line the first one I believe it was faulty but thanks for an outstanding company that stands behind their products; backs it up the way it should. Behind a good product there’s a great company. Bottom line I gave it a five stars because of their customer support and their prompt response. You don’t see such a response like this specially in these days anymore. Thank you for your time for reading this. Have a blessed day. I hope I was able to help.

I bought this back in October and had high hopes for it, but it certainly does not live up to its claims. I have attempted to inflate some tires with a small 12V air compressor, using the supplied adapter that hulkman included. It will run for about 3 sec and shut off. I've tried it with 2 different small, common, 12V air compressors, one of them brand new, same issue. Both work fine when plugged into the vehicle. Customer support was fairly quick to respond but you just end up running in circles with them because they offer no solutions at all. They only ask questions and answer none. They answered ZERO of my questions and have been of absolutely no help whatsoever. They kept telling me it was the compressor safety shutting off because the hulkman was over powering them. I guess that's supposed to make it ok? Hopefully I can just send this thing back as it is relatively useless if it cannot even inflate a tire. It does charge my phone and it did jump a friends car, but, then again, so does my cheap battery tender one I've had for 5 years. Certainly does not seem to be worth the price. I would look at other options especially at that high a price.

This battery charger is probably the best one on the market. It's extremely easy to use . If you buy it you won't regret your purchase. Just do yourself a favor and watch some YouTube videos to discover how to use all its features.
