There are drawbacks to non lead acid or gel batteries. Lithium batteries lose charge at a rate of 5-10% per 30 day period. So in a shop or store where you can potentially keep it plugged in it would be a decent device.
Cons: lithium is energy dense. (Average energy density 2. 5x3x2/8 will give you about 3500mha at 3. 7vdc) dropping a lithium battery on the ground can expose, pinch, short a cell. Which will possibly cause a runaway reaction. Lots of fire and smoke and you cannot put it out with water or by removing oxygen.
Positive points. Smaller, lighter more convenient.
Now the boost button. why would they not want you to use it? Simple. Charging lithium requires a smart charge controller. If the lithium batteries get to hot crystals will form and short the battery. So the charge controller will not allow the voltage to dip below the 19volt power range. Because that will likely mean the cell is compromised and charge will discontinue. Boost likely bypasses the charge controller and gives you direct power to the cells. So dont use it unless you are stranded.

18 months ago I got myself a rather bulky jump starter pack, which claimed to produce 600 CCA and 900 peak A. Based on SLA, has rather thick jump leads, and it worked fine for me. I still have it but haven't had my car battery go flat on me after the few times I got to use it. I have jump started a couple other people's cars with it though. Been replenishing the charge every 3 months or so as advised in the instructions. It has two cig lighter sockets, USB, and work light, reverse polarity indicator. 15V 800mA home charger, and a cig lighter charger which I haven't tried. It cost me 70 EUR, about as much as the battery I got for my car later.

Thanks, Eric, I been looking at your shows for almost a year I live in South Carolina and wanted to have my own shop someday but even after my injury in the military I still drive tank truck and work on cars in my spare time I just love the way you get into the troubleshooting to find what is the cause of each problem you face thanks once again for giving me a skill that makes me feel like I can find any problem in any situation keep up the good work. Your new best fan Johnny G.
PS: I must ask can I get the part number for that jumpstart kit

I'm not surprised at all. They have lithium batteries that put out 50 times their nominal amperage in burst mode. So if you have a 12 volt 5 amp battery, it becomes 15 volt 250 amps, and you can pretty much start anything with that. It's got a few issues, the lithium stuff is very volatile. It will also heat up like crazy and can cause itself to melt and set ablaze. What that jumppack is missing is some ultra caps in it to basically make it maintain the voltage and have more amperage.

Thank you Eric this has been a very helpful video in two ways. first, my 800 AMP Strongway booster box jump starter has a dead battery and now I know that it should cost me about 40 for a new battery. Secondly, since the thing weighs 800 pounds I have an alternate choice in jump starting systems in this new technology. I will still fix the Strongway jump starter as it was pretty spendy, but am definitely going to get one of these Rockford jump starters as well! Awesome little unit! :-)

Actually I totally enjoyed this product review by you because it was genuine. It had your first impression and interpretation of what you had in your hands. Then it had your genuine response to the idea that this thing actually works! Sure crank up that propane-fired forklift for yours pretty good! Do some more brother! I'd rather have a genuine first impression and then last impression then some scripted nonsense. In my own words,

My wife got me 1 for Christmas a few years ago. I looked at it and giggled. Then I bought a few auction cars for our car lot with dead batteries. I pulled the little giggle box out of my truck. It started every single car. It's actually started every single car I've ever used it on. Needless to say we now have 3 of them on the lot. The Noco brand are my favorites because of the serious jumper cables they come with. Great video: )

I have had mine for 3 years, I have jump started about 7 people stranded in gas stations or parking lots with mine. I liked it so much I bought one for my wife to keep in her car, very easy for her to use, without the possibility of connecting it wrong, she has used it once after leaving her lights on while at work. Delivers a strong performance in a small package. like me; )

I funded the Juno Power jump starter on Kickstarter years ago and it seems similar to this. Higher quality maybe, and it's 20, 000mah with all the outputs and an AC dock. Couldn't be happier with it. I jump people with it all the time, so much more convenient than cables. I don't leave home without it in the car.

bought a power booster at Walmart, it went the way of the doe doe bird after three years, it was always dying:
I'm still wondering,
those were 3 & 4 bangers, I had mine for big blocks, got any 400 cubes round about to plug that mighty man booster to.
just wondering.
