Like many folks, my car sits unused. My two year old battery decided it was weary of life and that holding a charge was against its physical beliefs.However, it would hold a charge for a week, then a couple of days, as long as I ran the engine for 30 minutes or so.Speaking of holding a charge, the first time it died, I had my neighbor help me jump the car, thinking this was a one time deal. The next time it happened, they were on vacation.I decided to see if there was a portable jump starter available. Searching Amazon, there are a plethora of products to choose from. I have to admit my choice was between others and it was reading reviews and overall price+product design that made my decision. I can't speak from knowledge of the device pre buying.I will admit, I was hesitant to buy this. I mean, a portable battery charger? Unheard back when I was a kid, and we trickle charged batteries for days, jumped our cars, debated whether we could touch the powdery leaking acid, and other things one did back when we walked uphill both ways to get anywhere.The charger arrives. The first thing that struck me was how small it is. The second thing was, no power cord. This thing charges via USB. I was thinking, no way, no way this can jump start a car. But, that's me, cynical and a disbeliever. So, I plug it in, watch the pretty blinking light, and think, OK, charge away little battery charger.The charge is full. Now, one thing, the cables are short, but that doesn't really matter, this thing is light and you just put it wherever there is a flat surface. I connect the cables. No spark, nothing. I am thinking wait, no spark? What? Oh, I guess you should turn it on. Important safety tip. Turn it on before using it.I get behind the wheel. Thinking, you know, if this doesn't work, how much is a tow truck. When is my neighbor coming home. Who decided we needed jam and jelly.I turn the key. Boom, it starts. Just like that. I disconnect the cables. I let the car run. I am thinking, wow.5 days go by. Same thing, battery is dead. Lovely. I check the charger. 4 bars. It holds a charge even after jumping my car. I jump it again. I go get some Mexican food from a local food truck. Luckily, I take my new charger. We are now calling him Mickey, after the trainer in Rocky. Just because. I get in my car. Turn the key. Nothing. Mickey is hooked up again, he starts my car.Rinse/repeat the above about 3 more times. I realize, not going to happen with my dead battery, need to buy a new one. So I take it in and Mickey is now idle.Now, filling up the tires. It's a little tricky, because you actually should read the instructions, not just plug it in and think whooshing thoughts. But, Mickey filled all of my tires. Oh, and Mickey overfilled my tires, as the person who replaced my battery told me, since my sensor detected the tires were more than full. Oh, and Mickey still had two bars after filling all four tires and jumping my car.In summary, this is a must have product. Must have for every car. Must have if the power goes out since you can charge your phone. Mickey will live inside my car for all time. He is a champion.Last thing, in terms of storage, everything fits inside the case. Even the medal I plan on giving Mickey as soon as I find an appropriate one. I might be gushing but this is an amazing product. And yes, it's put together very well, no loose parts, no scratches, no hidden nicks or anything like that. I know this because I have gone over every inch of Mickey (OK that sounds a little weird but this thing fascinates me, it's like I discovered alien tech or some cold war relic out of a secret Russian lab).Very much a buy recommend. I will stop now, I think I need to start my car and test the new battery ...

Very powerful, easy to use. Love it comes the needle for balls. With nice sturdy carrying case, convenient and functional. You can set the pressure and it stops when air filled to the level you set. Just make sure you choose the right measurement, it fills up really quick, choose wrong measurement will mess up your stuff quick. Haven't tried the jump start yet. But from the way air pump works, it has to be very powerful. Tried many handheld pump before, nothing comes even close.

Over all easy to use. I bought it to jump a car battery and it worked great. It packs enough juice to jump the battery a few times and charge my devices as well. The only gripe I have is the air pump nozzle came broken so I couldn’t air up my tire. Thankfully I had a separate air pump for that.
