Muy necesario

I've had this for a while and just found the need to use it for a dead battery on a 2013 Jeep Cherokee - charged it up last night and tried it today and the car would not even turn over - the jumpstarter turns it's self off when I try to start the car - save your money and don't buy this POS!!

What I particularly like about this car jumper is that it isn’t a single tasker and that it charges quickly if you use a charger that’s more capable than those 5V 2.1A chargers. I’ve tested to see if it can jump a 4runner – yes it can. No problem. I’ve used it as a power bank, which it does fine. The flashlight function is fine if you don’t also have a really good flashlight. It’s as bright as good flashlights used to be before the super high brightness LEDs showed up.The build quality is good – it feels solid. Nothing rattles and the case isn’t thin and fragile.

The first thing I noticed is that it feels like a toy. It feels like thin, flimsy plastic. It is compact, which is nice, but it does not work. I have tried it on two different vehicles, and it has failed to start either one. I am not sure what it is good for, maybe just a power pack for charging cell phones. if you need something to start a vehicle, this is not it.

This unit worked well for me to jump off my 4.2L TrailBlazer last week. The car battery was very weak and after following the directions and getting the green light it fired right up. It took the battery on the unit down to 50% after a single jump so I would definitely recommend you recharge it after every use because that last 50% probably isn't as strong as the first 50%. I haven't used it as a battery bank for portable devices, so I can't comment on that but it is a cool feature. The flashlight is kind of a gimmick, but it works if you need it. It also has a flashing mode and a red mode if you ever happen to need it.My favorite feature is that it charges with USB type C and it supports USB PD so you can charge it with USB C to C cables. My last jump starter, which failed, had to be charged with a special charger that had a barrel plug.My main complaints are the leads are quite short. They will work in most cases, but a lot of newer cars have jump points that aren't together on the battery, so that could definitely cause issues. I also really wish it had a case. You can just keep it in the box to have everything together, but a dedicated case would be a much nicer option.Overall it does what it is supposed to do at a pretty fair price. It does feel a little cheap and has the cons I mentioned above, but I still feel like you won't be disappointed with it.

Thankfully, I've only had to use this once on my truck, but it started on the first try after I hooked it up.Recharging is easy, and it gives you piece of mind when you travel.Makes a great gift.

Glorified flashlight

It's yet to save ME, but I can tell you, everyone loves me when I get their car started with this tiny little box!It also has a flashlight, and can charge your phone!
