About HULKMAN Alpha85 Jump Starter 2000 Amp 20000mAh Car Starter for up to 8.5L Gas and 6L Diesel Engines with LED Display 12V Lithium Portable Car Battery Booster Pack

87% found it compatible with their vehicle, but 13% faced issues
I had a cheaper off-brand version of these lithium ion jump starters which worked great for starting miscellaneous items like a lawn mower, etc. But when I tried to start a small 4 cylinder (1.6L) car engine, it did not work. I researched and found that many of these battery pack jump starters won't work when the car battery is missing or too drained to be detected by the battery pack starting circuitry. I then bought NOCO GeniusBoost GB40 but it did not work. I then returned the NOCO and purchased this Hulkman Alpha 85. Under the same test (no connected battery at all), setting the Hulkman into override immediately provided power to the truck and easily started the 5.7L V8 engine. I recommend this product based on my experience with respect to feature: Compatibility.
Alpha can jump-start all types of 12V vehicles.
The jump starter was fully charged but couldn't turn over my boat's small 6 cylinder chevy inboard engine.
82% appreciated the safety features, yet 18% found them inadequate
The jump-starter has a special mode that enables totally dead cars to start, which is significant as many competitive battery packs cannot do this task.
I chose this jump-starter for its safety features and cold weather durability.
I appreciate the jump starter's ability to bypass safety features and start a vehicle with a completely dead battery. Many competitors do not have this feature, which may be why people think their jump box is defective.
I recommend adding venting and an internal heat sink or fan to keep the temperature down when charging.

88% were satisfied with the starting power, although 12% not
The jump starter can start cars and trucks with completely dead batteries or no batteries at all, and has plenty of power.
I was skeptical about the starter's size and whether it would start my engine or not. But as soon as I connected the starter and turned the key, my engine fired right up.
I can start a totally dead car with no battery in less than 1 minute using the jump-starter.
The car had just enough power to bring up lights and dings but not enough to start it.

86% found it portable, while 14% disaggred
The jump-starter has a significant feature of enabling totally dead cars to start with its special mode.
The jump-starter is bulky, so I rated it 4 for portability. Smaller car jumpers are available that can fit in a laptop bag.
The jump-starter feels unnecessarily heavy for the power it delivers to my electronics.
The unit is too big to fit under a seat or glove compartment.
