Same here - never owned one of these.
They have Lii-on or some other battery and needs to be charged.

How do u maintain it? Do you need it to be plugged in at home all the time?
Because you rarely use them - only in emergency. Rest of the time?
These are the things that I am considering.

Besides the reviews can not be trusted. They are from China I believe.

I've owned other jumpstarters. They only have to be charged a few times a year when not in use. Although extreme heat is not good for their longevity, I keep mine in my car year round. The one I'm now replacing still works after 6 years, but is just beginning to swell.

Amazon seller is false advertising this product. I just got it and the manual doesn't state the peak Amp, but if u look at the official website on the J450 model, it says 2000A

I bought a gooloo didn't know anything about the brand i have had it for over 5 years now and I had a car with electrical issues and had to use it every time i started my car for about 6 months.
I could use it over 10 times before it reached 40 percent and charging it was pretty quick I left it in the car in 110 degree weather and in the winter when it was snowing it has never failed me and I have dropped this thing several times and now there is something rattling inside but it still works like new I had to tape it together because dropping it broke the case and it looks like crap but has not ever let me down I jumped a fork lift with it and even used it to move a car without a battery from one side of the yard to another I paid about $140 but it was definately worth it I would say I have used it over 200 times at least probly even more
