   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.

   With a big truck or most any diesel or 10L V8 powered vehicle this is the best, highest capacity jump starter for me to keep available. This has the power to turn over my rig or a 10L V8 engine provided the battery isn’t totally dead from damage, cell loss, etc. Plus this has a 4 mode large LED flashlight (P.4)at one end that will strobe, run at 50% or 100% light and do a red SOS if needed, selectable with repeat button presses. I especially appreciate the extra heavy duty cable battery clamps and all the safety protective circuitry (last 3 pix.). This has a big LED display to show power pack status and if there are problems. In addition to that this huge jump starter has well covered outlets to allow me to use it as a big powerbank. The USB C In/OUT Port can deliver Power Distribution (PD) Standard 3.0 65Watts of power and serves as a recharging port too. Note the Orange USB out Port in P.2 which indicates that it has Quick Charge (QC) 3.0 capability at 5V-3A,9V-2A,12V-1.5A. There’s a normal (Black) USB A Out port for 5V 2.4A out also. There is even a 12V DC “cig lighter socket” that can do up to 10A/Max 150W out. Why buy a separate powerbank when this will do all of this plus provide jump start power for my rig! Naturally I can’t use all the outputs at once. Best to keep the deeply padded foam box this comes with as secure storage for this device though it appears ruggedized. Oh, one more thing I have never seen is that this has “Pre-Heating Technology”. The jump starter can be used at -40 degrees Celsius by self prewarming its internal battery pack for 100 seconds. Then it can operate as a jump starter. Lithium cells don’t do well in really cold weather so this has an automatic turn on of the intelligent temperature control function according to the environment. That and all the features account for the higher cost but makes this very well designed product superb. The instructions are excellent too. This has a 24 Month limited Warranty with a US company. It includes a plug in wall wart for fast charging of the Jump Starter Powerbank through the USB C In/Out Port in as little as 90 minutes. A USB A to C cable is also included. I Highly Recommend this HULKMAN Alpha100 Jump Starter 4000 Amp 32000mAh Car Starter with -40℉ Start Tech PD 65W Lithium Portable Car Battery Booster Pack for up to 10L Gas and 10L Diesel Engines. It is superb with everything but a separate case. Keep the box! I hope you’ve found the information and my review helpful.

   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.

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

   Classic lithium battery for jumping, however beautifully constructed. USB ports, get the carry bag.

   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.

   I bought this for my 2016 Camero that kept on dying, has a new battery but if I don’t drive it one day it’s dead!! The car was dead approximately a month I couldn’t jump it with a car. I was stuck with the Camero in my assigned parking space, at my apt, living in San Diego was a complete inconvenience!!!
   Anyway I connect it after charging it, I didn’t get a “Ready” green light! I watched a YouTube review & figured out how to force jump it (exact terms I don’t know) BUT IT WORKED!!!!
   This is completely EASY TO US, lightweight, holds battery, & DOES EXACTLY WHAT IT IS INTENDED TO DO!!!
   BEST MONEY SPENT!!!!
