After 10 months of use I have no complaints. I've used it multiple times to top off car tires in the driveway and several times to jump start vehicles and it's always come through for me. I like that I can leave it plugged in all the time and in case of a power outage I can use it to plug in my CPAP machine!

I ABSOLUTELY love this machine! I have aired up tires, boosted my friend's van, and used it to charge phones during a blackout. Easy to use, easy to charge, not heavy to carry.

I'm a technician who works on building automotation, primarily industrial buildings. Often I start work on construction sites before there is power, and sometimes our controllers need programming before they have power. I'll use a portable transformer and plug it into this guy, and I'm set. I'll plug a fan into it as hvac isn't done yet, and it will keep me cool. I'll charge my laptop on it, my phones, etc. Has a huge capacity, and will generally take care of my needs. My vehicle ended up with a bad battery and often needed to be jumped before Wheels would let it be serviced. I probably jumped my vehicle 20+ times, and with the ability to turn it on and off I never had to deal with sparks (still follow the manual and jump with the frame though, battery explosions are no joke)And when my vehicle got a nail in the tire this guy got me going until I could get the tire patched. An incredibly useful tool that goes with me everywhere.

I bought one of these at an auto-parts place, because my (almost new) battery was going dead unexpectedly. It's great for jumpstarting, no doubt about it. But it can also put air in a tire, keep your USB devices charged or powered, and even provide some 120VAC. This power pack will be darned handy in the next power outage! At the price, you can hardly afford not to have one of these. A few days after buying the one I needed, I ordered another as a gift for a friend who fishes--something LIKE this is almost a necessity, and this particular one works, is easy to use, and is a great value at the price I got from Amazon (June 2021). Can't beat it!

After years of jump starting vehicles with low batteries, using cumbersome jumper cables and another vehicle, it was great to just pick up this portable unit, carry it to our pickup, and securely hook it up to the positive pole of the battery and the engine block before turning the jump starter unit on, avoiding any accidental sparking of the jump starter connections before the setup was secure. In our first try, the V6 engine of our pickup, which had been exposed to subzero temperatures and had a nearly dead battery, started after a few seconds of engaging its ignition switch. Fully recharging this portable jump starter took less than half an hour after starting the pickup.

This is the third one I have purchased!! My original one is still going!! I mostly kept it on our boat !! Just in case!! I have used it at the boat ramp several times!! I even had to let someone else use it on Lake Cumberland Poker Run!! We where heading into State Dock and got waved down by another boat!! The original one started two huge big blocks no problem!!! My second one I purchased went to my son for his car!!! I just purchased the third one for my wifes car. We live in Florida now so I know she needs one for her car just incase!! She drives a hundred miles a day!! So, it's great insurance to have one of these in your car, truck, or boat!!! Getting ready to buy a fourth one just to keep in our boat!!

Lighter for what it is, but hefty due to good battery capacity.Best one I've owned. The others are not adequate for longer term use, nor for shorter term.This one has all you need to jump a car, just sit it in the battery area use it's clamps. Easy and jumps the car well with the 1200 amps. As an air pump, it is easy to use, set tire pressure and let it go.Nice that it can charge phones and such with USB, but they should add USBC now that Apple has that cord standard for it's chargers. I've never used the 12V "cigarette lighter" port. Flashlight is merely adequate, but nice it is bendable to the position you need.

No disliked qualities but do read the instructions on this item. It's a named Brand product that has been around for a long time. Quality and power & need I say more?

I had one of those Lithium bricks. Only a higher-end one. Took it out and tried to start my old F150 with the strait 6.20 deg outside. It cranked for 4 or 5 seconds. Then shut off and you had to reset it for another 4 or 5-sec try.4 or 5 seconds does not even get you in the range for starting here in Minnesota.Gave it to my son. Keep this in your car in case you leave your lights on or want to charge your phone.I ordered a Schumacher SJ1332 with sealed lead acid AGM batteries.15 deg out. Galant with a dead battery. Crank crank crank 15 seconds " Varoom!!!"Walked over to the F150 hooked her up. " Varoom!!" off she goes.Had the Farmall 400 plugged in to heat her up. Hooked up " Varoom!!!" off she went.Heavy as heck, but she did exactly what I wanted it to do.Took it back in the basement, plugged it in for the next time.

This is our second one-The first one we used for a brief electrical outage- was able to plug in a lamp, cell phone and laptop! It’s was great! Also, husband used it to jump start a friend vehicle. This one was purchased as gift.
