5000A Jump Starter with Air Compressor, Portable Car Battery Jump Starter with 150 PSI Tire Inflator for Up to 10.0L Gas and 8.0L Diesel Engines, 12V Jump Box with 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 help Takes less space - more compact Cons: 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 fine. Does the job for MB GLK-350, starts the dead battery, need to wait a little sometimes

Loved it so much dad bought another one!!

Had the jump starter for about a year and a half now and never really had a need for it until recently when a neighbor needed to have their very dead battery jump started. The jump starter failed to start the car because as I later discover, the smart clip that I had that attaches to the battery won't work with a completely dead battery. I contacted customer support and they responded within 24 hours notifying me how to work with the completely dead battery but apparently, I needed to get an updated smart clip. In summary, after a few rounds of emails (all very polite and informative and all responding within 24 hours), they offered to send me the updated smart clip at no charge! I would have to rate that as excellent customer service!!!

I bought this unit to keep in my small suv just in case of a low battery. I was pretty sure it wouldn’t pack the punch that it claims and I doubt it does. I have jumped off a lawnmower, motorcycle and a compact truck. The truck wasn’t completely dead , but it was able to get it cranked. I think this unit is great for cars with”almost” dead batteries but if you have a V8, I would look for other options.

My car constantly draws power even when turned off. All cars do this, but the model I have is particularly bad for it. If it sits for a few days, like a long holiday weekend, it's dead. I had an old jump starter but it eventually stopped holding a charge. I bought this HPBS jumper about a year ago and have used it several times. On my own car and on other people's. It always starts my car on the first try and seems to deliver a lot of power. I've also used it to jump start my lawn mower for the first cut of the season. It holds a charge quite well, as I've gone months without charging it, and it works. It also holds enough power for multiple jumps on a single charge. I always plug the charger in once I use it, but did have to jump my car twice in one day, and the jump starter didn't drop below 80%.

I bought this because Aaa was using it to start my batteries. I have four other battery, chargers, and one other quick start. This is the best one by far.

I’ve given these to family and friends…I’ve started skid steers and pickups. Well worth having in each vehicle .
