Portable Car Jump Starter Master Thread
I am skeptical of such a small unit as well. This thing has an 800A peak output and but more importantly, like closer to 300-350A in cranking amps. This is not that much. In addition to the guy in the reviews who started his car in a snowy condition as well as the tester who started his JEEP without a battery (not recommended to do this of course), here is some anecdotal experience. Just received the unit this morning and charged it up to the max. Downside, you can only charge it via the 15v/1A input port which is only compatible with the provided wall charger and accessory socket (cigarette lighter) charger. So I assume charging an 18000 mAh battery from 0% would be quite slow and require at least overnight charging. Once it's at 100%, took it to a buddy who has had an older car parked for 5 years with a totally dead battery. Once the GOOLOO unit was attached to the battery, no indicator lights. As per the instruction manual, this means the battery has gone bad. It also said to hold the ON/OFF Switch for a few seconds until the BOOST light (green light) stays on. Went through that and did 2 cranks on the old car. First crank would keep cranking but not start up the car. Did that for 5 seconds. Second crank started it right away. This car has not been started for 5 years and the car's battery was connected and left as is. The recommended battery for this car is rated at 590CCA so given this GOOLOO is only rated at Start Current of 350A (3 secs) and 300 Start Current of 300A (5 secs), it was still able start the car. Conclusion, this is not a severe condition as it's a car and not a massive truck engine and it's not below freezing. But in short, for $75 on sale right now, this unit is worth keeping. The only downside I can see is the lower cranking amps and only being able to charge via a slow 15v/1A port. The bright side of this slow charging port is you can charge it via the cigarette lighter plug that comes with the unit. Hope that helps.

So, I noticed there is a great car battery thread. I thought we could use a car portable jump starter master thread given that many people are driving their cars less during this Coronavirus outbreak. So many are reporting that their battery have died even with just a few minutes of leaving the lights on. Amazon Canada has a good supply of portable lithium ion batteries that is supposedly able to jump start an automobile. Some are good and some will just NOT do the job.
This is the most comprehensive review video but the better brands are not available in Canada.
This is someone showing the 800A unit working after 30 days of not starting his vehicle, which is in the extreme (snow) cold and it worked:
Here is a reviewer who used the older 600A one to start a Jeep without the car battery!
Let's use all RFD personal experience and expertise and create a master thread about portable portable jump starter. Let me start with 1 find. After extensive reading of reviews and videos, this one seems like a good mid-level jump starter. And seller reviews seem more reliable than most on Amazon. https://www.amazon.ca/gp/product/B06X9R ... M3VY&psc=1
Add brands and units so others can benefit. In fact, if you have technical expertise to add, do share. Watts, amps, mAh, voltage are difficult to grasp for the average joe.
