i've only had one day, but this thing is awesome. I got it because I like how the PSI is over twice as powerful as most most are only at 1:20 I think this one is 260. It's all on my bike tires super fast and actually the air pressure gauge works to a T I use the manual gauge to make sure that I didn't rely on it and then I use the gauge on this jumper and it is right to the T, so much easier just let it go and measure . Like I said I pretty much just got this to jumpstart if needed and the fast psi, I have no idea head all these other extras such as USB radio light etc. I had gotten a Duracell one and anything under this psi super slow 120 psi even a bike tire takes forever we can walk back-and-forth & even for a bike tire took forever +++ If you go on road trips it's much safer to have the faster psi because if you're stuck on the road you don't wanna be a silly target waiting for your tires to if you go on road trips it's much safer to have the faster psi because if you're stuck on the road you don't wanna be a sitting target waiting for your tires to inflate.so much this is more compact some of the big wide ones that you can't even fit between truck seats

I have used this product several times over now. When I had a power outage, it helped keep my cell phone charged (which was my lifeline), and at other times allowed me to fill my car tire and basketballs with air. The radio also came in handy to keep up on current events. It has so many features that it is the perfect solution for a product that has a small footprint, but packs a punch for function-ability in the things it can do!

Everyone should have this., especially in California, where the electric utility turns off the power very often to prevent wildfires due to dry, windy conditions causing them. It will start your car, run your refrigerator/freezer, charge your phone, keep your computer/wifi running, and any number of life's necessities: lights, TV, if it's there to run, weather, emergency service contacts telling whether you should be evacuating, etc. It's a lifesaver, for so little money you'll find it hard to believe you didn't have it all this time! Need lights, not candles? Get this puppy! It really does the job; not gasoline in your garage, or MUCH MORE EXPENSIVE generator.

This little power supply is awesome. I use it for car camping. I use the radio/aux the most, followed by the light and usb charger. Haven't had to jump my vehicle or fill up tires yet, so I can speak on those, but I don't anticipate any issues. Feels solid, everyone's impressed with this little guy.

It matches expensive lithium power supplies with you consider the fact that lithium shouldn't be run below 50%.

This only thing I'm a little disappointed with is the lack of a storage space for the wall and dc chargers. I just tie them to the handle and it works fine.

Best power supply our there with all the amenities I need.

I really like this as a back-up power source when the lights go out. Only downside is the master switch has to be engaged to anything to work. When the master switch is on, there is a really bright LED on the front that lights up to the point where it is difficult to see the front switches.

Ran a 9W florescent lamp, 12v fan and charged iPod during the last power outage for over 3 hours on a full charge.

Update: After about 6 months the battery started to take only a partial charge. It now only runs a 9w florescent lamp for about 1/2 hour. I purchased a Duracell 300W, which runs the same lamp for about 6 hours, but not continuously.
