Scosche - Portable Car Jump Starter with USB Power Bank - Gray/Black

This product is awesome. I left the lights on in my car and instead of calling someone or buying jumper cables I decided it was time to invest in one of these. Ran to the store, charged it up and jumped my VW GTI. I drove it to run errands and the car battery hadn't recharged enough when I tried to start it again so I had to jump it a second time and it had enough charge to jump it twice! I was so relieved! This also can charge other electronics with the USB port. The flashlight not only turns on solid but can flash which would be good in roadside emergencies. The black case that holds everything was much nicer than I was expecting. Because the case is so nice I think this would especially be a good gift. There is also room in the case to hold a few other things. I added a ziplock bag with rubber gloves so I don't get my hands dirty from getting into the hood of the car. I do leave the battery in my car in 100F+ heat. I have noticed that the battery looses its charge sitting in my car even if I don't use it so I would recommend checking the charge on the device regularly. I estimate that over 50% of the charge was lost after 3 months in my car not being used. I did some research and that seems to be a fault of lithium ion battery technology and not this specific product; so keep that in mind if you purchase this. I make it a habit of opening the case and checking the charge when I vacuum the interior of my car. Overall good buy.

Picked this up because I ran my car battery down and needed to get ~something~ to fire it back up, and figured this would be far better for emergencies than jumper cables. Got it home, charged it, took it out and the car started up instantly. Drove it about a half-mile to the gas station to fill up (which wasn't enough to charge the battery) and had to use it again, and it worked just as well, no issues. Again, this morning when I left for work, it worked beautifully. Hopefully the distance was enough for the alternator to charge the car battery back up, but if not, this little jumper pack is still showing a full charge after three jumps, so I'm not worried at all about being stuck here. I don't know if it's got enough power to turn over an eight cylinder engine, but if you're running on four or six, this thing's got enough power to give you multiple jumps if need be. Highly recommended.

Nice to have this gadget handy when the unexpected happens. 2 weeks after purchasing this devise I unfortunately had an opportunity to use it. I must have left something on in my car overnight so I experienced a dead battery the following morning. Although I have AAA service, by the time it would have taken them to travel to the house, hours would have passed. I pulled out my jump starter , properly made the easy connections, and seconds later I was able to start my car. This is a must have product for the car glove box or trunk.

I was skeptical at first when I saw this and then I went out to the parking lot and my car wouldn’t start the battery was dead and so I purchase this and I plugged it in it was very easy and I noticed that the battery pack that comes with only had one light on so it was still very low and yet I plugged it in to my battery press to the boost button and within one minute the light came on and I could start my car it’s amazing and I can fit this thing in my glove box

I have an Outback 2011. It has worked when the battery has no enough power to start the engine but enough power to turn the radio on. If the battery is more dead than that it will not work. If I had to choose again I would go for a bigger battery version and with a fast charging capability as charging takes long. I think that for smaller engines will have probably more success. Outback is a 2.5L

Overall this is the last thing I will buy from bestbuy, I bought this 3 months ago because i drive 500 miles weekly to see my family, guess what first time i need it it’s not working, I went to bestbuy and they said sorry we don’t replace it after 15 days and now I will have to figure out how to contact the manufacturer. I will just buy from Amazon at least it’s easier to return.

I love bought 2 from different locations and somehow they work beautifully as an extended battery charger for USB powered devices and portable applications likea fan however before I used it as a powernoption for those devices, I used the BOOST featire to jump start my dads 6cyl car and my friends 4cyl... within moments the pack got so hot I couldn’t hold it without wrapping it in a towel.

I had some reservations about using this as an emergency jump starter, but it worked when my vehicle’s automatic headlights stayed on while shopping for groceries. The 300 amp was enough to start the SUV that still had some juice in its battery. Yes, the 700 amp model would probably be a better match for this vehicle, but this one worked.
