Car Jump Starter, 12V Portable Battery Charger (up to 7.5L Gas&5.5L Diesel Engine) Auto Lithium Battery Booster 2000A 18000mAh Jump Pack with Smart Jumper Clamps, USB QC3.0, LED Light, Compact

Handy to have in your car.
Great little jumper. It holds a charge for about a year without using it. Depending on what type of car or truck you are jumping you can get 1 to 3 jumps out of it before it needs to be charged. It takes about 4 to 6 hours to fully charge.

Better than getting a boost from a live car battery
When I got in my SUV to go to church it started just fine. When I came out of church my battery was completely dead. A couple of men there at church tried to boost my vehicle off, but it wouldn’t turn over. After leaving the cables on both batteries for more than a half hour the battery would allow the horn to honk but the engine only made a clicking noise. I called and asked my son to go to my house and get this charger and bring it. I had recently purchased it and had not used it yet. I bought it to boost my riding lawn mower. My son reluctantly agreed to go get the charger, but stated that if a car battery could not start it then it was a waste of time to go get the charger. He had purchased one of a different brand and he had to return it because it started his car but the engine died and the charger didn’t have enough energy to start it again. He did get my charger and bring it to the church. The engine wouldn’t make a sound when I tried it before he put the charger on. As soon as he connected it my vehicle started. He and the other guys were surprised. But my engine died. My son almost lost it because he just knew that it was not going to start again. He put the charger back on and right away it started. Again the engine died, and again it started right up. My son and the guys that were helping me all marveled at the power of this little charger. I got the vehicle running but I had to stop and get gasoline before I went home, so I had to kill the engine at the service station, and it wouldn’t turn over without the charger. After I got started again I went to the auto store to get the battery checked. I had to get a new battery because that one had dead cells. Since the battery was still under warranty I didn’t have to pay but a few dollars for the new battery.I am so pleased with with this charger not only because it is a great product. But also because I am a little ol’ 73 year old lady and I had a piece of equipment that the young men said wouldn’t work. I will tell every woman that you need to get this charger. And all of the men, who are not too proud, need to get one also. (Just joking about you all being too proud).

IDK how but this thing works great
When I first bought this and seen how small the wires going to the jumpers cables are I figured they would be no way it would work. I know about electricity and according to my math anyways The wires are too small, no way they could carry the amperage necessary to start a V8 engine with a completely dead battery. Then I tried it my 98 Buick with a 3.6 liter v6 had a completely dead battery. When I say completely dead I mean no lights on the dash not even an interior light I mean capital D dead. . I plug the The peace in to the end of the unit hooked up the jumper cables and it didn’t do anything I had to turn it on and off a few times I’m sure there is something I’m missing I’m not one for directions eventually the light came on and showed a voltage The car came back to life I turn the key and the car started right up. I figured that would have drained the battery but it still showed all four lights. I was impressed put it in the trunk of the car and forgot about it. About a month later left the interior light on again in my 1998 Ford van with the larger V8 engine. I grabbed it hooked it up and it actually cranked the van right up though it did turn it slower than The V6 in the Buick. But honestly who cares as long as it starts. That knocked it down to two lights out of four. I recharged it forgot about it. Then the stupid hurricane came and I gave it to my girlfriend down in Tampa. She used it to charge her phone three or four times Because her power was off for almost a week. Once it was completely dead the unit does take forever to charge from a USB port. I don’t have an exact figure but it’s over an hour per 25% when using a 3 amp charger. So she gives the unit back to me I put it in the Little rescue bots I have I keep in the trunk of whatever car I’m driving and forget about it this time for several months. Then I go to my dad’s house we go to move his early 2000 Chevrolet truck with the larger V8 yet again completely dead battery no lights or anything and though yet again it turned the engine much slower than normal It cranked it up though it did take two or three tries taking two lights off of the battery indicator. For the money this thing is most definitely worth the price. I’ve since used it for everything from riding lawn mowers to jet skis 4 cylinder six-cylinder and V8 cars I probably jump 10 or 12 vehicles with this so far. I don’t know how it works I’m guessing it has some kind of a capacitor in the little piece that plugs into the battery bank that has the jumper cables on it and I’m at the age now where I really just don’t care how it works but I definitely know that it does. So if you’re one of the people like me that’s kept from getting one of these because you’re like oh that thing’s entirely too small to start my V8 automobile I assure you it will. I will say if you hook it up and it doesn’t do anything turn it on and off a few times it seems to not want to do its thing occasionally. How are you as it is I hook it up I turn it on and off until the unit boots up on this little screen with dashes and then it’ll show a voltage Then you can crank the car.
