I carry this on my motorcycle. Have already used it twice, not on my bike though. For friends that needed it. Does what it says and battery life is good.

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.

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

Had to use it recently. My only regret is not ordering more than 1. I am so upset they are sold out. Worth every penny.

Works well and comes in a nice travel case. Was able to charge laptop off of this in a pinch too.

It was not charging properly and battery life is not great

never worry about a dead battery again with this emergency product in your car. Easy "jump" to get you home or to a battery store and no call to roadside.

Bought this after needing a jump on my battery. My coworker had this and it was beyond convenient and got me the help i needed. Now it just fits in my car with no space taken.

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.

Good size for a motorcycle, I will also carry in the car for an emergency.

Very compact and easy to use. I threw away my old bulky jumper cables.

Both the Car Jump Started since my battery charged, but periodically drained and I needed a jump from the auto club. Instructions were easy to understand, the unit was easy to charge with the included USB cable. The charger comes with accessories to charge a cell phone and other equipment

They are really easy to use and small to have in the car!

Got this because I have a car battery that keeps dying & not sure why. Product works great, is quick and love its size. Fits in my glovebox and center console great so it's out of the way when I don't need it. Love that I can charge my phone on it as well.

This portable car battery jumper has saved my a ton of money on calling road side assistance, and charged my phone on numerous occasions. This jumper in a box goes everywhere with me. Had to purchase more than one, and it’s a good deal if you can find it on one of the “deals of the day”.

Easy instructions easy to use. I hooked the charger up to my completely battery dead battery, hit the boost button, waited a minute to charge the car battery, turned the key and I was on the road! Also handy to have around as an emergency charger for the Florida hurricane season.

Did exactly as intended. Every female driver should have one available in vehicle.

I was able to get this as a "Deal of the Day" item, so the price was perfect for me. It does surprisingly well as a jump-starter and even cooler that it is a battery pack for electronics. It doesn't take too long to charge, but make sure to keep it charged for roadside emergencies.

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 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
