Saved the day ... err, days!
I bought this for "in case of the battery dies" to carry in a car I tow behind a motor home. Battery has been tested, but there are enough electrical gremlins using more than my alternator can feed. I thought I had it charging, but once again stopped for lunch and the battery would not turn the engine over. Good test time. I grabbed this jewel from the back seat, and followed the instructions. Wife turned the key, Vvrrrooooom! Ignition, Houston. Great. Over the past 4 months, we have had occasion to jump the car, same conditions. Finally, the battery warranty expired, and so did it's reliability. Wife went to the car wash and the staff left the key on which drained the battery (which was getting to the end of it's service life anyway). A line of cars coming out of the big robo, and the car won't start. Staff was trying to figure out how to get something close enough and who might have jumper cables. Wife reached in the back seat and handed them Mr. Bolt Power. They looked at her like she had lost it, and then at each other ... wondering what this little thingy was going to do to spin the engine over. They hooked it up, she turned the key, and Vvrrroooooooooom back in to life, one more time. New battery time ... that's handled, but we will keep the little green machine handy, ICoEmergency for someone else hopefully. The indicator after multiple starts, and 4 months, shows we had gone from 100% to 98%. I decided to charge it back up to 100%, which takes some time (slow charge), and put it back in the car. One minor complaint ... the flashlight doesn't work at all. Not what I bought it for anyway, so I could care less, and in my case not enough of an issue to return it or mark it down more than .01%. And that nice little case keeps it all together.

Incredible 900 peak amps cranking power.
Updated 6-5-17: I just used this jump start my Ford F-350 with 6.2 liter V8 engine, it jump started instantly in a seconds.
This car jump starter is awesome. It features 900 peak amps, 18000mah to charge smartphones and tablets for a few time, dual USB, and the most importantly there is a Digital display to indicate power level.
Bolt Power finally developed a jump starter with 900 peak amps for heavy duty vehicles. Battery deliver high output current, extended cranking power, numerous jumps per charge and a 12 months warranty. This unit also feature with SMART CABLE CLAMPS that offers reverse polarity protection. Like all the jump starters units, D29 has rugged construction and safety components to stand up to everyday use.
It is made with high graded industrial copper to ensure maximum power transfer to the vehicles such as SUV and trucks. Bolt Power claimed the unit can handle 6.5 liter gasoline engine and 4 liter Diesel engine.
Package included USB charging cable, car charger, wall charger, user manual, jump start instruction and D29 portable charger that packed in a soft shell bag. I also took a few pictures to display the product.
Overall, I love this unit. I purchased it a week ago and it works flawlessly.

... bought this thing a few months ago and it's like buying an insurance policy
I bought this thing a few months ago and it's like buying an insurance policy. I haven't used it yet but it is nice knowing you have it along. This thing stores easily and it looks nice. Well protected with the hardened kind of shell it comes in and it should hold up well. For such a little item, it is supposed to be able to start almost anything and if the quality of it is such this should be what the Dr. ordered. I think I might buy one for each of the grandkids and their parents....that would be 16 more of these.
Update; I have used this several times and it is well worth the money. It is so compact and easy to use....not getting out the jumper cables and trying to get the other vehicle maneuvered into position to jump start. It recharges easily as well and stores in small spaces.

Works great!!! Much better than anticipated
This thing works great. I'm really surprised how well. I jumped my son's Dodge truck with Hemi V-8 when all it would do is click, and it fired right up. I checked the charge on the booster afterward and it showed 98%!!!! I jumped it again a day later (been working on truck) and same thing, clicking but booster fired it right up. Checked charge on booster after two boosts, still had 97%. This thing is much better than I thought it would be.

A handy device.
A very handy device. I tested it on my SUV by disconnecting the battery and attaching the clamps to the battery cables and it started up my vehicle twice without draining the device from a 100% charge. You must first press the override button on the clamps till it displays a steady green. This is done because the device was reading a completely dead battery due to it being directly connected to the battery cables. All of this is explained in the device's manual.
It haves some weight to it but it do haves a nice carrying case. The con I have against the product is that it's made in CHINA and not in the USA. There are other products that are made in USA but unfortunately this is not one of them.

Really compact and multi-use!
This external power source for jumping your car is a great addition to anyone’s car emergency pack! It is much smaller than I imagined from the picture and comes with a variety of assessor he’s including charging cords for both the car and the wall and USB plug-ins for iPhone micro USB and others. Thankfully I have not had to use the jumper cables yet, but I don’t have any doubt by looking at the construction. Will update it for some reason this assessment is wrong.

It is compact and easily stored in the car.
My truck storage in winter for a few months. This little beauty will start autos and cycles literally all day long although something is wrong in your life if you need so much jump starting a car or truck. Nothing wrong with this unit except it makes you long for dead battery to jump so you can show off! It worked like a charm, small and compact, easy to handle. This item works as advertised and provides sufficient power for portable devices as well as jumping a car battery. It is compact and easily stored in the car. It also recharges with wall charger or cigarette lighter charger easily.

this worked awesome to jump my jeep
this worked awesome to jump my jeep. It even jumped my 6.7 liter diesel ford when the dual batteries in the diesel wouldn't start the truck. I am super impressed. The manual says it won't start an engine that big, but it worked that time for me.

Bolt Power D29 review
I recently had a chance to use it, and I was to jump to cars. Just make sure to check the video on you tube with regards
to the over load button which needs to be press when the battery charge is low.
I am going to purchase another one for a second car.
