About HULKMAN Alpha85S with -40 Preheat Tech Smart Portable Jump Starter
Overall Feedback:
85% positive
92% found it compatibile with vehicle
I used the jump-starter to start my full-size bronco with a 5.8 L V-8 engine and it worked perfectly.
84% appreciated the safety features
I purchased the 85s model for my small SUV and the quality and functionality are top notch.
This product is 100x better than other jump starters that are cheaply made and stop working after a year of not using them.
91% were satisfied with the starting power
The jump-starter was fully charged out of the box in about an hour.
I was skeptical about the number of jumps it would provide before needing to be recharged. However, I got over 30 starts before needing to recharge it. It seems to go down about 3% per jump on a 3.6 liter V6. The first time I used it, the car started twice after without needing to be jumped. It was like it gave life back to the battery.
I started the car on the first try with the jump-starter.
My full-size bronco with a 5.8 L V-8 engine wouldn't start, so I used the jump-starter to start the truck.
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.
I tried the jump starter on my car with a dead battery and it worked perfectly, giving me peace of mind that I won't be stranded waiting for help anymore.
The jump starter has an override feature that allows starting even if the batteries are completely dead.
