Beatit Yellow B9-PRO 600A 14000mAh Portable Jump Starter (Up to 5.5L Gas or 4.0L Diesel Engines) Auto Battery with Smart Jumper Cables

I have actually had one of these for 2-3 years now, and just bought one of the same brand for a Brother-in-Law. The one I just bought didn't charge, but Beatit send a new one after a quick email conversation (always had a response within a day, usually within an hour). So their customer service is great! Onto the product:For the last 2-3 years I have used my Beatit a lot more then I even expected. Here's what I learned about it:ProsHolds a charge really well, when it isn't allowed to freeze or get extremely hot (talking 100+ degrees) very often.I have jumped a gas engine up to 6.0 liters (Chevy Suburban) many times, up to 5 times on one charge when I was trying to diagnose a battery drain issue. I also jump started a Cummins once for someone on the side of the road. This thing always jumped them like they had a new battery. Very impressive.Charges phones really well, and I like that I have two USB charging ports so I can make good use of the very large capacity by charging two devices at once.Comes in a strong and well made carry case, which has room to put USB charging cables along with the Beatit and its accessories.Beatit feels very solid, with a hard rubber around the case so it is easy to hold.ConsFlashlight is a nice touch, but don't expect to use it for much because it isn't very bright.Why did they bother putting that compass on there? It is garbage and useless...Jumper cables are VERY short, like barely long enough to reach each end of a big battery. This makes this useless for a Mercedes Sprinter, which used to be my work vehicle, because they have the battery cables under the seat with a jumper running to under the hood, but no where close to any metal that I can connect the negative jumper cable to.Overall, most vehicles will be able to be jumped by this. I couldn't believe it jumped that Cummins like it had a new built in battery in it! Very solid, has worked 2-3 years through fairly heavy use for a portable charger and jumpstarter. I would not recommend letting it freeze or get hot very often, it is a battery after all.

Worked great the first few months I had it. Needed it again about 5 months later for a jump. Fully charged it and nothing. It won't hold a charge anymore. Cant even use it as a battery pack for other electronics.

My AAA car battery was dying fast on me. I knew that I was still under warranty so I could call them and get it replaced for free but I still needed to use my car and I had no time to wait for the truck to arrive so I asked a few people for help when stranded. A few really nicely helped, some did not...Eventually, I was very glad to purchase the Beatit Yellow B9-PRO 600A 14000mAh Portable Jump Starter until I would get the free time to call AAA to come and replace it. I used it for a couple of days until that time.My car has a 3.8L V6 engine and this kit worked very well. It is small enough that you can keep it in your glove compartment (providing that it is not full like mine is) or simply in your car trunk.One full charge can restart your car more than 10 times. I am very impressed by it.You can also use it as a light or to recharge your phones. As a light it is not very powerful though.The kit can be recharged either via the standard power plug or in your 12v cigarette lighter adapter.I decided to not go for the more expensive models because this is something you need to use only once every blue moon.Apparently, it is a good idea to recharge it once in a while if you are not using it because it empties itself slowly.

This thing looks nice and charged well. Easy enough to connect. Sadly it would not start my car. I tried a couple of time over a 45 minute period. The last time I let it remain connected for a good 30 minutes prior to attempting to start it for the 3rd and final attempt.Thankfully another parent was watching and had jumper cables. Started up first try.

Beautifully designed, engineered and packaged - and most importantly - IT WORKS as promised!!!! I bought it because I camp frequently on fishing trips out of cell phone range and carry an electric food cooler I run from my car battery. I've run my battery down a couple times and luckily was able to find help for a jump. But I didn't want to worry, so bought this. It arrived fully charged and about a month after my brand new top of the line Sears battery ran down -VOILA!! I jump started it immediately on the first turn of the ignition. It will also charge your cell phone and computer. The storage case and all components are elegantly designed and high quality - worth twice the price.

Product is boarderline on a 5.4 liter ford v-8. Works great for ATV's Lawnmowers etc. but a cold start on a larger V-8 is problamatic.

I didn't expect much for $30 but the reviews were good so u have it a try when my car battery in my Kia was slowly going out and every day I drove it, it got worse. I was needing a jump about 10 times a day towards the end and this was a life saver. First it took literally 10 seconds to hook it up and another 10 to start the car. The first time, fully charged battery. This thing could run many many times without needing a charge. I would use it constantly and not charge it and it never got below the second to full line. I was amazed. Then my sister was impressed and she bought one and loves it. I went to Auto Zone for them to test my battery and his big ol commercial battery jumper wouldn't do the trick. My battery is tiny! It would crank but no start. So I pull out my little jumper to see if it might work and guess what, first try and it started. The Auto Zone guy was in awe that this tiny little jumper jumped the battery that quick first try. He was in disbelief and took pics of it to buy for himself. To summarize: recharges the battery in seconds, easy to hook up, cover with nice case and 2 chargers, takes a long time and many many uses to drain the battery. It's got tons of power. It's easily my favorite car gadget I own. Buy it, you will not be sorry!
