Top customer reviews
After posting a one-star review I was contacted by the manufacturer and they very kindly replaced my battery since it was still within the year warranty period. New unit is working great so far (haven't had to jump the kid's car all week though!). Will update review in the future if it doesn't last, but at least on the customer service front Kmashi is a manufacturer that stands behind their product and a brand to be trusted.
* Original Review*
Worked fine for the first few months - my teenager (and friends) are "unlucky" with frequent dead batteries. Jumped a variety of cars, including SUV's like a Ford Explorer, it's a lot easier to deal with than jumper cables. Unfortunately, after about 6 months I get a strong "burning electronics" smell when plugging it in to charge, and the battery gets super hot next to the charging port. So there's that. Keep some jumper cables in your car, just in case.
Its capacity was very low. One jump start would drain it completely.
The company promptly responded to my emails and replaced it, even though I should have been charging it at least ever 3 months.
I wanted to put the new one thru the paces before forming an opinion on it.
I have an old truck that has been sitting unused for almost a year. The battery was so dead a charger wouldn't even fire up.
After priming the carb, I hooked up this little wonder, waited for a solid blue light on the cable led and hit the key expecting to see smoke.
The truck started! then stalled. I started it again. After warming it up I decided to drive it around the block to loosen things up. It had developed a clutch issue from sitting so long so I had to start it many times. After close to a dozen starts the Kmashi still had 3 bars of charge.
I have killed a few of these over the years (other brands) as a professional mechanic by cranking to long and overheating them. All of today's crank were in the 2 second range.
I have set a calendar event to remind me to charge it every 2 months, I hope to get peace of mind for a long time with this.
I was not paid for this review or given a product. I highly recommend it.
It small product with a punch... I have a 14 years old vehicle that can drain the battery when there is too much load and the alternator is not running. When the alternator is operating battery reads at 14.7 volts and goes back down to 12.7 volts at rest. After visiting the park and leaving the headlights on by accident when I got back to the car, I could not find anyone willing to help. By the time the second time it happened I had already purchased this battery starter. What a difference... took it out of the box, hook it up just as the instructions indicate and on the first try, the pack was on for a few seconds, turned the key to the on position and all the lights in the dashboard turned on and when I turned the key to the ignition position the engine started like nothing ever have had happen. I recommend it, a must have tool...KMASHI 400A Peak 14.8V 8000mAh Compact Car Jump Starter Power Bank Battery Charger with LED Flashlight and Advanced Safety Protection
Upon arrival I fully charged the unit, and 18hours later it was totally dead again.
The unit is so weak that the built it led light will run it down in about an hour, for reference a tiny button battery will run an led for about 20 hours!
I never got to try to use it to jump a vehicle but I doubt it could jump start at motorcycle, and certainly never a car.
I won't ever buy this brand again, I have an Anker unit that does not have the jump start function, but holds a charge well and I've never had it run down unless connected to a load. This KMASHI is garbage.
