So good!
I had a dead battery with the car in my garage. I was dreading the pushing the car out of the garage, etc., to jump the battery when my woman friend said let me use this! So quick and easy and saved the day. I immediately bought one for myself to have on hand. No more cables needed!

Product is a Lifesaver
I was having some charging issues with my motorcycle and occasionally needed to jumpstart the bike. I picked up this jump starter and have used it several times and it worked exactly as needed. It had plenty of power to start the bike. After one jump start I still had 3 of the 4 lights left which meant I had another jump start or two left. I typically charge it after use and once a month and it keeps a full charge. I would definitely recommend this to be kept as part of your motorcycle gear.

Amazing!
I opened this tiny little thing and thought it would never work. I charged it up and it takes quite a while to charge. It says 2 1/2 hours, figure more like 6! And first use: It started my old Massey Ferguson tractor from a dead battery that would not even click the starter! I clipped it on, turned the key. Hmm, not very great, it would crank but not very fast. I left it hooked up for 45 seconds or so making sure the gas was turned on and everything set. Hit the starter button and that thing cranked like it had a new battery in it! Amazing! And this tractor has a 4.2 liter motor!

Jump Starter works but flashlight doesn’t
Just opened and put it to charge … I had a feeling that something was no ok, no blinking lights showing that it was charging at all…. I left it charging anyway … after a few ours… tried the flashlight and does not work, long and short pressing the bottom, nothing …. For fortune the jump starter function is ok… that was for what I purchased it… but disappointed, because I bought it because of the brand , I have 3 battery chargers from them and are solid

Should also come with a wall adapter.
Seems like a great product. It needs to come with a 2A wall adapter plug in. This would allow you to do the initial charge.It comes with a tiny, thin storage bag. This is not good for protecting the item or cables and clampsCharge it in a well ventilated area or outside.For the price it should include the 2A wall charger (sold separately) and provide a storage box not a bag.If they were to put this in a plastic case like a flambeuo or Plano flat storage box it would protect all the components and separate them. It would also store easier in a car or truck. It may also prevent accidental water intrusion and corrosion on the electrical components.

Worked after over a year stored in trunk without re-charging
I received this as a gift over a year ago. I charged it, and put it in my trunk, forgot about it till I had to use it yesterday. There was only one blue light (since I had not followed the instructions to recharge it), and I’m happy to say that it worked on the first try to start a dead battery! I’m pleased!

I Like it
The size and weight are great. Charged right up even though it came fully discharged …no complaints because it was on sale for half off, and it charged right up to full charge like it should, and it worked great when I needed it to start my 1300 cc V4 cruiser.. as others have said there’s also a big piece on the end of the jumper cables that plugs into the battery pack.. it should be pictured but no points off; it doesn’t really make a difference since it’s in my backpack

I’ve owned and used an older Schumacher jump starter for a number of years and love it. Recently my neighbor vehicle problems and I loaned him my old one and replaced it with this new one. Even though it’s half the size and half the weight, it is just as, or more powerful as the old one.

The product may be good, but I was going to give this as a gift (auction item for charity basket).

No time to return it so took the manufacturer’s box my husband’s came in and transferred the charger to that box.
