Jump Starter - 3000A Car Battery Jump Starter for Up to 10L Gas and 8L Diesel Engines, 12V Portable Battery Jump Starter Box with 3.0" LCD Display

Compact, worth the money, easy to use, light weight, safer than cables.I Bought the 3000A models for our family midsize passenger cars. Charged them and put them in the vehicles, but who hopes for a dead battery?!Within a month it happened. Pulled out this compact little brick, popped the hood, and attached the cables. Perfect! Started my car. When it was time to return from my destination it succeeded on the first attempt. After two jumps, it still shows 91% charge. Cool thing is you can charge it from your vehicle's USB port while you drive. I have an appointment with BMW to replace the battery, but I am not sweating it. I keep driving with a dead battery because it is so easy to jump. It takes 1-2 minutes. I've driven four times, requiring a jump on each end of the trip (8 jumps). It has worked every time on the first attempt.IT WOULD BE SUPER COOL IF IT WERE ALSO A TRICKLE CHARGER!! No complaint though. I bought it to jump a dead battery and it performs like a champ. I imagine there is logic in the circuitry that prevents a cross connection, so when you start from this device, there is a delay of about one second (or less) then the engine turns.Pros over cables:Two connections versus four (most trouble jumping is due to bad cable connections)No danger cross connecting (I witnessed a battery explode in someone's face years ago)No issue getting a second vehicle in proper position to jump the dead car (like the shoulder of a freeway)No issue FINDING (or waiting for) a second vehicle for helpTakes less space - more compactCons:It must be charged to work (I've jumped 8 times with 100% success, but the device was always charged at least 80% - I do not know at what % it fails).

Works great! Started a V8 truck, riding lawnmower, and a motorcycle at the start of the riding season, great device to have. Quality built, and still using!

This purchace was for my daughter. She says the she used the portable charger on a friend's vehicle and got her charged up and home safely. It's small but a good design and the cables are easy to connect. Good deal for those who may travel alone.

Worked like it is supposed too. I jumped my car off in no time from a completely dead battery. Would give 5 stars but the battery clips feel cheap. Excellent for the price though.

I haven't had to use it yet but it's in a nice case. Looks real sharp. I like the flashlight on it.

Works well. Is that twice when the alternator went and the car turned right over. Only used 3% of battery each time.

Not impressed at all. Feels like there is no real batteries even inside it. Compared to my other one. Hope it works feels cheap & low quality at this point I'll try it out. Ad had me pumped up like it was a big unit with power even wires to clamps are cheesy thin. I already have a feeling it's not going to do what I need it to do

I was suspicious this could start a completely dead car, but it did quickly and with0out issues. It's also a USB jumbo battery to charge your cell phone if you need it. This was worth the price for peace of mind and its compactness.
