Customer Ratings & Reviews

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

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.

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.

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 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.

Within days of buying it I had to jump start my wife's car at the train station where it had been sitting for days. So much easier to connect than using my truck. Also, I really dislike jumping batteries with my truck because I don't want to risk frying my electronics if something goes awry.

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.

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

My car wouldn't start. and I could not put the gear shift into neutral, to back the car our of the garage. .My friend takes me to Best Buy, where i purchased this jump starter. We went home , charged it for an hour and hooked it up to my car. Car stars instantly. great product, with handy flashlight!!

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.

bought it, used it and it works a snap! loaned it to a friend, gave it back in 30 seconds as it started his old beater in seconds.

It was not charging properly and battery life is not great

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.

Good, compact jump starter. Remember to recharge regularly. I do at oil changes.

I bought this jumper for my wife and she has had no problems using it. Very compact and powerful.

This thing was pretty neat. Very well packaged. It came with a cool storage case that I wasn't expecting. I had no complaints with it other than I didn't read the description well enough. It wan't strong enough for V8 motors. Perfect for 4 cylinder motors though!

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

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”.

I have had a different brand for some time now and it served me well. When I saw that Best Buy had it, and at a better price, I had to buy it and try it. Well, I'm happy with it, it's great quality and a great price. It's like 10 times more powerful than your standard USB battery pack.
